Oceanographic Properties Essay Example for Free

Oceanographic Properties Essay Oceanography is the study of the sea and oceans. It is composed of the geological study of the ocean floor and ocean features. The geological aspects of the oceanography include physical oceanography which is concerns with the physical attributes of the ocean water for example currents and temperatures and the chemical oceanography whose main focus is on the chemistry of ocean waters. Marine biology is the study of the oceanic flora and fauna. Oceanography also studies the meteorology which is the interaction between the atmosphere and the ocean. The Indian Ocean, Atlantic Ocean, the Pacific Ocean, Arctic and Antarctic oceans and the Mediterranean Sea among others are integrated in oceanography. Naturalists as Thompson, a Scot, and John Murray a Canadian were among the first pioneers to discover and study oceanography. (Johnson 2005). The paper examines some of the physical, chemical and the marine features present in the oceans. Oceanographic Properties Physical oceanography refers to the discovery and the study of physics and the geography of the ocean currents and water properties. The major components are the dynamics of ocean currents on scales from centimeters to global, the ocean wave phenomena the distribution of heat and salt and their transport through the ocean basins, the exchange of the momentum, heat and freshwater between the ocean and the atmosphere, the interaction between the ocean and rivers, estuaries, ice and marginal seas. Physical geography has important application in global climate, oceanic mixing and coastal studies and in the studies of primary production, hydrothermal vents and oceanic flux and storage of carbon dioxide (Robert 2005). The ocean is composed of a mixture of 97% pure water and 3% other materials examples as salts, gases, organic substances, and the undisolved particles. Pure water determines the physical properties. The ocean is measureless covering 71% of the earth surface of which 65 % is considered open ocean- waters that lie far away from the costal ocean. Oceans are different with an averaging depth of more than two miles and containing vast life all over it even in the deepest bottoms. Oceanic life is composed of two major categories; the pelagic (ocean water) and the benthic (the sea floor). Pelagic is further divided with accordance of water depth. Fig 1. 0 parts of the ocean The first 200 meters of the ocean water is called the neritic zone which includes the seashore and offers abundant food for the larger animals due to the plentiful of small organisms. The ocean zone extends from 200 meters deep to the bottom of the ocean. Often the ocean zones are classified according to the amount of sunlight they receive. The top part which photosynthetic life is found called euphotic zone while the preceding zone is the dysphotic zone where light is too dim to support photosynthesis. The aphotic zone where there isn’t any light rays. Littoral zone is closest to the seashore covering a distance of 600 feet from the shoreline and is divided into three zones namely; the supralittoral which is submerged due to unusual high tides or during storm. The intertidal zone lies between the high and low tide lines then the sub-littoral which extends from low tide up to 200 meters. Ocean water salinity refers to the amount of salt found in the 1,000 grams of water. Majority of the salt content in the ocean comes from land but some originates from the undersea volcanoes thus the average ocean salinity is 35 grams of salt per 1,000 milligrams. An estuary refers to the point where fresh river water meets the oceans salty waters. Its salinity is different from the salinity of the ocean adjacent to it Most estuaries are found at river mouths and are thus long and narrow, resembling a channel. The water pressure increases with the increase in depth while the temperature which is the measure of hotness or coldness of an object is divided into three temperature vertical zones. ? Top layer is the surface or mixed layer and it’s greatly influenced by the solar system. ? The following layer is the thermocline and the temperature drops with the increase in depth, ? Then the third layer is deep-water layer and at this point the temperature decreases slowly with an increase in depth. In the ocean, the water density depends on the temperature, pressure and its salinity. For instance cold salty water is denser than fresh and warm water. The density further subdivides the ocean into three layers namely, the surface mixed where the temperature and saline content differs hence no great effect on density since it’s in direct contact with the air. Next layer is the transition zone where water remains cold and dense and it’s the barrier between the surface and the bottom zone allowing little water movement between the two zones. The bottom zone is where water remains cold and dense. This has been illustrated by the figure 2. 0 below. Fig. 2. 0 Density layers in the ocean Ocean currents The current keeps the ocean in a constant motion and moves large amounts of water into great distances. It is driven by wind forces, gravitational forces and tidal movement. There exists different types of current namely the Antarctic Circumpolar Current, Eats wind drift, the North and Southern equatorial currents, the Peru currents, the Kureshio current and last the Gulf Stream. They flow in gyres which are loops of water. The gyres spin in a clockwise direction and in the southern hemisphere they do spin in anti-clockwise direction. The currents can be illustrated in the Figure 3. 0. The United States of America normally experiences the effects of the Gulf Stream currents in the Northern Atlantic zone, the equatorial current and the Canary current. Mostly affected coastlines are the Florida’s East coast, North Carolina and the Newfoundland. Figure 3. 0 oceanic currents Marine Biology By looking at the ocean surface, it is difficult for one to see the great diversity of life that exists in the ocean. The ocean inhibits different kinds of flora and fauna. They include the mammals, which are animals with backbones hence they are vertebrates. They unique features is that they breath air lungs, give birth to young ones, produce milk, are warm blooded and are covered with fur. They are the seals, sea lions, walruses, the sea oter and the polar bear. Other oceanic creatures include the giant squid, angelfish coelacanth, lantern fish, gulpers whales, sharks, fishes of all kinds. Other forms of ocean features are the coral reefs. (Cone 1992) Oceanic coasts There are various types of coasts in the ocean and the beaches are only but one type. They are divided into two categories namely the primary coasts and the secondary coasts. The primary coasts were created by non-marine processes. They happen because of changes in the land, such as river deltas or lava flows while the secondary coasts were formed by marine action and are caused by changes in the ocean, such as the creation of barrier islands or coral reefs.

Four Basic Principles That Underpin Construction Projects Economics Essay

Four Basic Principles That Underpin Construction Projects Economics Essay Construction economics like pure economics, its mainstream equivalent is concerned with the allocation of scarce resources. This is far more complex that as it first appears. Many of the worlds resources (factors of production such as land, labour, capital and enterprise) are finite, yet people have infinite wants. We are therefore faced with a two-pronged problem; at any point in time there is a fixed stock of resources, set against many wants. In an attempt to reconcile this problem, economists argue that people must make careful choices, in terms in construction choices about what investments are made, how these are constructed and on whose behalf. Construction is greatly dependent on the changes in the UK economy, and particularly on those which are the direct result of the government policy. Construction output is a response to the demand for buildings, and this is result of derived demand for other products and service. Variations in the Gross national product will, in this way, influence the demand for construction work and the associated level of employment. There are four basic principles that underpin construction projects; supply, demand, markets and types of business. Supply The word supply used in economics is normally defined as; the total amount of good or service available for purchase; along with demand, one of the two key determinants of price. This definition states that supply can be calculated by looking at the demand. Supply can also be affected in many ways the main one being demand. However there can be other factors that can affect supply as well, it could be the price of other related goods for example; paper is made from trees, therefore a tree would be considered a related good to paper. If the price of harvesting a tree increases the supply for paper will decrease. The line marked S is the supply curve. The curve depicts the relationship between two variables only; the price and quantity supplied. The supply curve can also shift left or right if there is an increase of supply for a certain product of service, it will increase the quantity and reduce the price. A change in supply refers to a change in behaviour of sellers caused because a factor held constant has changed. As a result of a change in supply, there is a new relationship between price and quantity. As the supply has changed or shifted to the right, we can see that the quantity has increased but the price has decreased. Supply must always be looked at when beginning a construction project, for example if the supply of housing has decreased there would be no point in purchasing a house for refurbishment and selling it on as the demand would have also decreased. Therefore when beginning a project, the related supply should be checked carefully and the project should be started at the estimated time of equilibrium. Demand The word demand is used widely through out the economics world and it simply means; desire, a desire for someone to own a good or service also having the ability and willingness to pay. Just like supply there are several factors that can affect demand the main one being supply. However there are other factors that can also affect demand this can be the price of related good or even income. The more income a person gets it is more likely that they will buy something. The preference of a certain good can also increase demand, for example if a large amount of people prefer a pair of jeans over a pair trouser then the demand for jeans will increase and the demand for a pair of trousers will decrease. The red line shows the demand curve. The curve is two dimensional and depicts the relationship between two variables only; price and quantity demanded. Looking at the diagram on the right, we can see the red demand curve, there is a shift to the right, this tells us that the demand has increased; therefore supply has increased along with the increase of price and quantity. For example, there would be a sudden demand for pancakes on Pancake Day, because of this the supply will increase, the price and quantity will also increase. Elasticity of demand can be defined as, the responsiveness of quantity demanded to a change in price. (John Sloman, 2003, page44). If the price elasticity of a product is known then predications can be made on the effect of price and quantity for a supply curve. The size of change in supply and in demand can be calculated for comparison. It is measured in percentage. This graph shows three constant-elasticity demand curves. D1 is a vertical curve; the quantity does not change if the price changes, therefore it has zero elasticity. D2 is a horizontal curve; this is infinitely elastic. Any price below P0 gives an infinite demand and any price above gives a demand of zero. The curve D3 if unitary elastic, this means when there is a given percentage change in the price of the good it will result in an identical percentage change in the quantity that is demanded. In terms of a construction demand is very similar to supply, for example after completing refurbishment works on a house, it should not be sold immediately. It should be sold at a suitable time; it should be sold when the demand is high. The reason for this is, when the demand for housing is low the price of the house will decrease, and when the supply increases so does the price. Markets A command economy is where supply is controlled by the government, they decide what type of good and services are needed and decide how they are distributed. A free market economy is all allocation of scares resources is determined by supply and demand. There is no control from the government, and there is free trade without any major problems. A mixed economy has the best of both; there are parts of the command economy and parts of the free market economy, a mixed economy is an economic systems that allows for the simultaneous operation of publicly and privately owned enterprises. Depending on the type of market there is a construction project can be affected in many ways. For example a command economy will just build houses if they are needed, they will sell house if they need to be sold, and there is little room for choice. A free market will build entirely out of will; if it is needed then it will be built. If someone has the desire and the correct funds to build a house, then they will. And if someone wishes to purchase a house, they will agree an amount and pay it off. As above a mixed economy is the best of both, however in many circumstances the price for housing price does rise and fall. But, anyone person can build at their own will, but they will need planning permission. Types of Business There is a large extent of business structures they all have different purposes but all have the same goal to be successful. The types of business are; a sole traders, partnerships, public limited companies, private limited companies, housing associations, non-profit making organisations. A sole trader is; an individual owns and runs their own business without the need for employees. For example this could be a small corner shop. A partnership is; there are two or more people working together to make a profit. The partners together own the business and normally share out profits equally between each other. This could be a small/medium sized grocery store. A public limited company (legally abbreviated to plc with or without full stops) is a type of limited liability Company in the United Kingdom and the Republic of Ireland (and other jurisdictions where companies law is derived from English law) which is permitted to offer its shares to the public. For example Natwest bank is a public limited company. Housing Associations provide housing, they are more commonly known as Registered Social Landlords or RSL for short. They function as a normal business and any profits that may be made a put back into the business, so it is a non-profit making business. An example of a housing association is London and Quadrant housing trust. Non-profit making organisations tend to help the local area or community and all surpluses are not distrusted but it is put back into the company to help it grow and achieve its goal. When the recession hit the UK the supply and demand for housing were affected. Banks were not lending money for people who wanted to buy houses and many people were not interested in buying at all, as interest rate were too high. Therefore the demand for new housing dramatically decreased as a consequence the supply also decreased. Scarcity Scarcity is the fundamental economic problem of having seemingly unlimited human needs and wants, in a world of limited resources. It states that society has insufficient productive resources to fulfill all human wants and needs.  [1]  Certain goods are likely to remain inherently scarce by definition or by design; examples include land and positional goods such as awards generated by honor systems, fame, and membership of elites. These things are said to derive all or most of their value from their scarcity. This can be a large problem, many thing in the world are scarce this includes land, food, and other resources. For example land is a scarce resource as there is only a limited amount available, but it is always in demand. Also, scarcity can affect many things in construction for example raw materials are a scarce resource as it is always in high demand. Raw materials are sold in what is called the factor market. This is because  raw materials are factors of production alon g with labour and  capital. Raw materials are so important to the production process that the success of a countrys economy can be determined by the amount of natural resources the country has within its own borders. A country that has abundant natural resources does not need to import as many raw materials, and  has an opportunity to export the materials to other countries.  [2]  Timber being a raw material, is a very scarce resource as the amount of time taken for it to grow is not quick enough for the ever growing human demand. Task 2 The construction industry is heavily reliant on borrowing money to complete many projects. Many people can not afford to pay off a construction project completely. Hence, when the rescission hit the United Kingdom it had a large affect on it. Banks could not afford to lend any money that would go towards constriction projects; from this moment on the construction industry is still suffering as clients can not get hold of necessary funds to pay off the contractor. Due to the downfall of the construction industry the housing industry has also declined as a result of this. Office for National Statistics modelling suggests that the sector declined by 0.7 per cent in the first quarter of 2010, following the 0.9 per cent fall in the final quarter of 2009. UK GDP as a whole rose 0.2 per cent in the first quarter of 2010, the same data revealed. The weak data suggests that the brief growth period in mid-2009 was a false dawn as the construction sector has lagged behind ever since. Most predictions had suggested that 2010 would see further decline in construction, however, with many predicting falls of around 5 per cent this year to add to the double digit declines of 2009. While the reasons for the further contraction in the sector were unclear, some surveys have suggested there is lower spending in the public sector as projects are delayed in the run up to the election on 6 May. The rate of growth in the whole economy of 0.2 per cent is a slowdown f rom 0.4 per cent growth in the final quarter of 2009.  [3]   The UK government has plans for public spending and it is hoped that these will include major construction projects, such as roads, schools and other public buildings. This would help the construction industry and those companies that supply the construction industry to ensure continued employment for many. Construction accounts for about 6 per cent of the economy, but analyst said that, despite its modest size, the rapid deterioration in the sector does not bode well for the economy, particularly following poor manufacturing figures last week.  [4]   Quite simply the main economic problem in construction is the fact that no one wants to build anything, because they can not build anything if they have no money. When a construction project commences the client needs to get a hold of enough funds to be able to complete the project. Since the recession many construction projects have been put on hold, the reason for this is that bank were reluctant to give out any loan and any loan that they did give had very high interest rates, as a result of this many people were put off to even consider taking out a loan. Hence many people have been made redundant as companies could not afford to keep them employed. As more and more people became redundant, people became competitive, to try and fight for their job. Only after the recession can work go back to normal, but it will take time for construction projects to go back how they were as construction projects are very expensive, and many of them are based on credit or loans given out by banks or other similar sources. The term business cycle (or economic cycle) refers to economy-wide fluctuations in production or economic activity over several months or years. These fluctuations occur around a long-term growth trend, and typically involve shifts over time between periods of relatively rapid economic growth (expansion or boom), and periods of relative stagnation or decline (contraction or recession). These fluctuations are often measured using the growth rate of real gross domestic product. Despite being termed cycles, most of these fluctuations in economic activity do not follow a mechanical or predictable periodic pattern.  [5]   Construction activity in the UK continued to decline in Q1 2009, but at a marginally slower pace than in Q4 2008. The net balance of surveyors reporting a decline in activity increased from -47 to -45. All sectors experienced declines in workloads, although such declines moderated in the private and, particularly, the public housing sectors. Private industrial and private commercial workloads continued to fall at pretty much the same rapid pace as in the previous quarter. Meanwhile, declines in infrastructure workloads accelerated and public non-housing workloads resumed their decline having increased in the previous quarter. Private housing workloads continued to fall sharply Q1 2009, but a slower pace than in Q4 2008. Workloads fell at a slower pace in the South West, the Midlands/ East Anglia region, the North, Scotland and the London/ South East region. In Wales, workloads continued to fall at the same sharp pace as in the previous quarter. In Northern Ireland, private housing workloads fell at slower pace. Public housing workloads continued to fall, but only mildly. Workloads increased in the Midlands/ East Anglia region, they stabilised in Wales and they fell elsewhere. In Northern Ireland and Scotland, the pace of decline in public housing workloads picked up sharply.  [6]   Capital costs are costs incurred on the purchase of land, buildings, construction and equipment to be used in the production of goods or the rendering of services. In other words, the total cost needed to bring a project to a commercially operable status. However, capital costs are not limited to the initial construction of a factory or other business. For example, the purchase of a new machine that will increase production and last for years is a capital cost. Capital costs do not include labour costs except for the labour used for construction. Unlike operating costs, capital costs are one-time expenses, although payment may be spread out over many years  [7]  in financial reports and tax returns. Capital costs are fixed and are therefore independent of the level of output.

HNES Native Species Gardens Misrepresentation and Dismissal of Exotic

Public green spaces are complementary areas in urban centers, designed to create recreational space for public use and cultivate-natural scenery. There are many public green spaces on York University's Keele campus such as the woodlots, the green roof near Ross building, Passy garden, Maloca community garden, and HNES Native Species Garden. The Native Species Garden is a naturalization project founded in 2005, in front of the Health, Nursing and Environmental Studies building. The project led by Dr. Gerda Wekerle and various members of the Environmental Studies Faculty, and grounds management staff to propagate native species as there are many exotic species on campus. Although, the objective is pure and beneficial to the ecology of the campus, the ramifications are lacklustre. The garden invites xenophobic principles, formulates stereotypes and cultivates misinformation about exotic species. The purpose of this essay is to discuss the different images of exotic species and the integ ration of these species into public green spaces on campus. Exotic species -sometimes invasive- are organisms either moved via human disturbances or geological and meteorological events, often displacing species from their habitat. Yet, the word "invasive" is attached to exotics as a negative construct without considering advantages or disadvantages of the plants to humans and the environment. The story of exotic species is learned as a militaristic metaphor and Larson (2008) confers, "We have made an enemy of invasive species to justify controlling and subjugating them"(p 16). One example is Garlic Mustard, a herb species native to Europe and some parts of Asia; mainly used as spice.

Trends in Computer Architecture Essay -- essays research papers fc

Trends in Computer Architecture Since the introduction of the first computer, the search for computer architecture that is faster, smaller, and more efficient has been a constant goal of the computer industry. The first computers were large, heavy machines composed of thousands of vacuum tubes. The development of the transistor created the next evolution in computer architecture, the microchip. This is the architecture used in the current generation of computers. Like its vacuum tube predecessor, this architecture of utilizing transistors, can only go so far. Moore’s Law predicts that the number of components on a chip doubles every 18-24 months. At this rate each switch will eventually become the size of an atom. When this happens the laws of quantum mechanics must be used. A new evolution in computer architecture will need to be developed to handle the unique laws of quantum mechanics. This architecture is already being developed and is called a quantum computer. Quantum computers work in a rather distinctive way. Instead of using traditional bits, they use quantum bits, or qubits. These qubits are particles that can take on the unique states required for quantum computing. The best way to understand how a quantum computer works is by example. A basic example is to take a register composed of 2 bits. Using a classic register, these two bits can have a value of 0,1,2, or 3. Now using a quantum register with two qubits, the register can have a value of 0, 1, 2 and 3 all at ...

Bluetooth Applications

BLUETOOTH APPLICATION ABSTRACT In the current scenario the world is plagued by accidents which are primarily due to human errors in judgment and hence thousands of lives are lost. These accidents can be avoided if only there was a mechanism to alert the driver of approaching danger. This can be done by monitoring the distance between nearby cars and alerting the driver whenever the distance becomes too short. This is precisely the aim of this paper.In this paper we propose the use of Bluetooth Technology by which we can check the speed of the car whenever it comes dangerously close to any other vehicle up front, thereby saving very many lives. CONTENTS: 1. INTRODUCTION 2. ROAD ACCIDENT STATISTICS 3. OPERATION 4. AUTOMATIC BRAKING SYSTEM 5. REPRESENTATION OF OUR IDEA 6. CONCLUSION 7. REFERENCES INTRODUCTION Since Bluetooth devices are capable of communicating with eight other devices simultaneously we can monitor and check the speeds of up to eight cars simultaneously, thus preventing accidents.Thus if we have two Bluetooth enabled devices in two cars the devices automatically communicate with each other when they come in the range of up to 100 meters of each other. The range is dependant on the power class of the product. Power transmission rates vary in many Bluetooth devices depending upon the power saving features available in a particular unit, bandwidth requirements, transmission distance. The statistics of road accidents is tremendous and highlights the need for such a system. The following is a statistic on the number of road accidents occurring each year.ROAD ACCIDENT STATISTICS OF INDIA 1970-2003 | |   |   |   |   |   |   | |Sl. No. | |Source:   Data received from States/UTs. | s OPERATION Because of traveling at high speeds there is a possibility of having accident. The figure 2 shows that when two cars or more come within the distance of 10 km at high speeds there is a possibility of having accidents. The Bluetooth radio is a short dist ance, low power radio operating in the unlicensed spectrum of 2. GHz and using a nominal antenna power of 20 dBm. [pic] At the 20 dB the range is 100 meters, meaning equipment must be Within 100 meters to each other (about 328 feet) to communicate using the Bluetooth standard. With the help of this technology we can send data to the eight devices. The group of eight devices is known as piconet. Here we have a piconet and a scatternet, in the piconet M is the master and S1 to S7 are the slaves [pic] Radio communication is subjected to noise and interference, as the 2. 4 GHz frequencies are shared between the all device in piconet.So the Bluetooth specification has solved this problem by employing what is called as spectrum spreading, in which the Bluetooth radio hops among different frequencies very quickly. There are 79 hops starting at 2. 402 GHz and stopping at 2. 480 GHz, each of which is displaced by 1 MHz. The Bluetooth avoids interference by hoping around these 79 frequencies 1600 times per second. So in order to avoid it we use bluetooth equipped car, in which each car have bluetooth transmitter and receiver. And the every car should have mini computer to monitor the relative position of the car with the other car. pic]When any car comes close together bluetooth device sends warning signal to the car. Based on the type of warning signal received the computer sends signal to the brake control system to slow down the speed of the car. There are two types of control signals. First type of signal control the speed of the car and the second type of signal is to overtake the car which is moving forward. Schematic diagram of car: [pic] AUTOMTIC BRAKE SYSTEM: The automatic brake system is the next generation braking system for controlling the speed of the car.On receiving the control signal from the traveling car the computer inside the car manipulates the signal and gives control signal to the braking system. There are four main components to an automatic brak ing system: †¢ speed sensors †¢ pump †¢ valves †¢ controller [pic] Automatic braking pump and valves The computer constantly monitors the distance between each of these cars and when it senses that the car is getting too close it moves the hydraulic valves to increase the pressure on the braking circuit, effectively increasing the braking force on the wheels.If the distance between two vehicle is within the 100m the Bluetooth devices get enabled and if the distance come closer within 10m the automatic braking system takes the control. After the speed of the car is reduced and distance increased the hydraulic valves decreases the pressure on the braking circuit, thus effectively decrease the braking force on the wheels. The following steps show the various functions of the hydraulic valves: †¢ in position one, the valve is open; pressure from the master cylinder is passed right through to the brake. in position two, the valve blocks the line, isolating that b rake from the master cylinder. This prevents the pressure from rising further should the driver push the brake pedal harder. †¢ in position three, the valve releases some of the pressure from the brake.REPRESENTATION OF OUR IDEA In the figure 7 when car A and car B come within the range of 100m both the Bluetooth devices get enabled and if any one of the car comes too fast then the bluetooth device sends a warning signal to the other car and it processes the signal and gives it to the automatic braking system. pic] CONCLUSION: The Bluetooth technology is being widely adopted by the Industry leaders. The possibility for new applications is very exciting with this Versatile technology. It provides a simple, logical answer to all the Problems-which is built a single common radio into every mobile computer, then neither do companies have to worry about WAN, nor do communication companies need to worry about building external cables. The Bluetooth communication device will thus be a small, low powered radio in a chip that will talk to other Bluetooth enabled products.Bluetooth has been designed to solve a number of connectivity problems experienced by the mobile workers & consumers. Thus, this technology helps make the electronic devices more user friendly and helps address various other problems like accidents. ———————– Fig 1 CAR 1 CAR 6 CAR 4 CAR 3 CAR 7 CAR 8 CAR 5 CAR 2 MINI COMPUTER INSIDE THE CAR Fig 2 M S72222222 S1 M2 S2 S1 M1/S S1 S1/S3 M1 S3 Fig 3 Fig 4 Fig 5 Fig 6 Within 10m Sends warning signal Receives signal and control the speed of car Fig 7

Growth Mindset Essay

Asking Effective Questions Problem Solving Approach in mathematics classroom because it engages student in inquiry, prompting them to build on and improve their current knowledge as they â€Å"construct† explanations and help them solve tasks at hand. In a â€Å"Constructivist classroom† students are seen as the ones who are actively creating their own knowledge†. This is done through questioning to h I need respect, motivation, encouragement, determination, to have confidence in your students. 8 Tips for Effective Questioning 1. Anticipate Student Thinking (plan the possible questions to stimulate thinking and deepen student understanding 2. Link to Learning Goals 3. Pose open ended questions 0 help build students’ self-confidence, help them respond at their own stage of development and allow for differentiation Invitational stems that use plural forms and exploratory language invite reflection. Huinker and Freckman (2004, p. 256) suggest the following examples: As you think about†¦ Given what you know about†¦ In regard to the decisions you made†¦ From previous work with students†¦ When you think about..As you consider†¦ In what ways†¦ In your planning†¦ Take a minute. 4. Pose Questions that actually need to be answered 5. Incorporate verbs that elicit higher levels of Bloom’s Taxonomy Verbs such as connect, elaborate, evaluate and justify prompt students to communi- cate their thinking and understanding, to deepen their understanding and to extend their learning. Huinker and Freckman (2004, p. 256) provide a list of verbs that elicit specific cognitive processes to engage thinking: observe notice remember contrast interpret evaluate summarize visualize (â€Å"see†) differ distinguish decide identify compare predict explain conclude infer relate consider describe 6. Pose Questions that Open up conversations to include others. 7. Keep Questions Neutral 8. Provide Wait Time (use strategies such as turn and talk, think-pair-share and round robin to give students time to articulate and clarify their thinking Ms Hastings does use different Instructional Strategies. She builds strong relationships with her students, set high expectations for performance and has a good understanding of their needs to reach success in her classroom. Ms Hastings first has a strong belief in the â€Å"Growth Mindset† by setting high expectations and showing student they can learn as opposed to the belief of â€Å"either you are good at math or not†. Teacher shows students how they can succeed and achieve through â€Å"application and experience†. Their words and actions make it clear that the past does not dictate the future. If a teacher promotes the â€Å"growth mind-set†, they can focus students on â€Å"self-development, self-motivation and responsibility† and help them develop the mental determination to continue to improve. She clearly sets objectives and provides feedback to her students to help them progress. By reinforcing effort and providing recognition, students believe they can succeed. These strategies all provide students with the belief that they can positively affect their learning She also uses various strategies to promote thinking and learning in the classroom. She uses cooperative learning, uses effective questioning and graphic organizers. She uses team building exercises and forms a base group, in which they learn and work together for the semester. In reading the Capacity Building Monograph in â€Å"Asking Effective Questions in Mathematics† in showed how you can change Learning to becoming something you get for a short time to permananence and building a deeper understanding. In Ms. Hastings class, the 8 tips provided in this monograph are great strategies being used in Ms. Hastings class. One of the most important influences in student achievement is the relationship between teacher and students (Hattlie, 2009). By Ms. Hastings telling success stories this provides encouragement to her students. Ms. Hastings class is preparing her students with the skills of the â€Å"21st Century Learner†. She is doing this by helping her students set personal learning goals, self-assessment for understanding, therefore, making learning permanent, accessing tools and resources for enhancing their understanding and using their learning in rich meaningful tasks in real-world contexts. These students will learn problem-solving, critical thinking and using their prior knowledge and skills to apply them to new situations. Two challenges faced by adolescents is the belief they are not good at math, therefore, find it challenging and are less engaged in math class. The second challenge is to make math learning become permanent through student engagement. This means using Instructional Strategies to ensure students are engaged in their own learning and self-assessment. One of the challenges faced by adolescents is the belief they are â€Å"not good at math†. This may be imparted by their parents belief they were not good at mathematics and do not ask more from their children. There needs to be a shift from this belief from all adults involved. They must recognize and affirm the importance of mathematical literacy for all. In the Ministry’s Numeracy Report (2004), students need the â€Å"ability to deal with the  fundamental notions of number and change in order to make sense of mathematical information presented in everyday contexts† (Paulos, 1988, pg.). Mathematical literacy in important for both employment and post-secondary admissions. Therefore, as teachers, we need to take advantage of the abundant opportunities for fostering mathematical literacy across the curriculum. As with Ms. Hastings, has a strong belief in the â€Å"Growth Mindset† by setting high expectations and showing student they can learn as opposed to the belief of â€Å"either you are good at math or not†. Teacher shows students how they can succeed and achieve through â€Å"application and experience†. Their words and actions make it clear that the past does not dictate the future. If a teacher promotes the â€Å"growth mind-set†, they can focus students on â€Å"self-development, self-motivation and responsibility† and help them develop the mental determination to continue to improve. She clearly sets objectives and provides feedback to her students to help them progress. By reinforcing effort and providing recognition, students believe they can succeed. These strategies all provide students with the belief that they can positively affect their learning She also uses various strategies to promote thinking and learning in the classroom. She uses cooperative learning, uses effective questioning and graphic organizers. She uses teambuilding exercises and forms a base group, in which they learn and work together for the semester. The second challenge faced by adolescent if to ensure their learning has â€Å"permanence†. This is done through strong conceptual foundations in math and ample opportunities for students to demonstrate their knowledge. I also believe that as teachers we need to use effective instructional strategies to emphasize student ability to think, use problem-solving skills and build on prior knowledge. Ms. Hastings uses various strategies to promote thinking and learning in the classroom. She uses cooperative learning, uses effective questioning and graphic organizers.

To be able to prepare our students as 21st Century Learners, we need to increase our math competence through professional learning to be more effective. The Expert Panels Report on Student Success in Ontario Mathematical Literacy, Grades 7-12 (May 2004) looked at at-risk mathematical learners and came up with a number of themes: Effective teaching and learning begins with the needs to the adolescent learners and have a good understanding of their development stages Connect the learning in math to the lives of the students (having rich meaningful tasks that connect to real-life contexts) Ensuring they have a strong conceptual foundations to be able to apply their knowledge and continue their learning Instructional learning strategies empahisize problem solving and building and one’s own understandings To improve students’ performance, teachers need to link instruction more closely to assessment More professional learning opportunities for teachers to strengthen their competence in math Technology to support learning and have more accessibility to students who are struggling in math Also extra support for  Ã¢â‚¬Å"at risk† students to close the gap Strong leadership and strong planning to create an effective learning environment in which all the needs of the students are met and success is promoted. 2.

Abraham Lincoln Bio Essay

Since his death in 1865, Abraham Lincoln has been immortalized as one of, if not the greatest hero in American history due to his role in ending the Civil War and abolishing slavery. He led our country through its’ darkest days and was able to prevent the south from successfully seceding and preserving the United States. Throughout history many have been called heroes, some deservedly and others not. Lincoln’s recognition as a hero is valid because of his many achievements and his leadership style. Lincoln was born in February 1809, in Kentucky. His early life was difficult, losing his mother to illness at 9 years old. The family was poor and Lincoln needed to work to help support them. As a result, he had very little formal education, but it was this hard work and humble beginnings that ignited the spark in Lincoln to learn. When he was a young man the family moved to Illinois and it was there that Lincoln learned the law and became interested in local politics. In 183 4 he was elected to the Illinois State Legislature. He taught himself the law, was admitted to the Bar in 1836 and also began a career as a successful lawyer. Between 1847 and 1849 he served one term in the U.S. House of Representatives. As a result of the increased opposition to slavery, the Republican Party was born and Lincoln joined the party in 1856. It was his anti-slavery views and the continuing passing of laws to protect slavery that further sparked his interest in politics. He ran unsuccessfully for the U.S. Senate but obtain national exposure from the race due to his unique communication and debating techniques. It was this exposure that found him as a candidate for President in 1860. He was elected the 16th President of the United States and the first President from the Republican Party. Because of his well-known views on slavery, the  secessionists began their plans to split from the Union prior to his taking office. The Civil Was began in April of 1861 with the attack on Fort Sumter in South Carolina. Almost immediately in his role as President, Lincoln was faced with the most challenging situation of any President prior to him. His decision-making and communication skills, though unpopular at times, would be a vital part of his success over the next several years. Lincoln possessed strong social intelligence skills. He was sensitive to other people’s feelings and moods, and he was particularly adept at reading people. Lincoln had a great ability in understanding the motivations of others, and was skillful at getting others to cooperate with him. He knew to be pleasant and approachable while also being fierce when fighting for causes he believed in. One tool that Lincoln would use was storytelling. He would use stories from his past which would put people at ease while at the same time relaying his point in a clear way. Another method he would use was to ask questions to get his rivals to see things his way. His communication style and speeches were simple and logical. Abraham Lincoln’s most famous speech was the Gettysburg Address given in 1863 at the dedication of the National Cemetery after the battle at Gettysburg. The speech last just over two minutes and was an example of how Lincoln understood his audience. There had been much â€Å"Pomp and Circumstance† throughout the ceremony and many long speeches prior to his. The words he chose were short and to the point, but were full of inspiration and emotion. The speech focused on the principles of the founding fathers of our nation and the words from the Declaration of Independence that â€Å"all men are created equal† and that all men have the unalienable rights to the pursuit of life, liberty and happiness. One of the main things Lincoln wanted to accomplish with this speech, was to rally support for the 13th Amendment, which would abolish slavery and was in jeopardy of failing to pass in Congress. Lincoln again used his influence as a communicator to get the 13th Amendment passed. He would spend hours with his political rivals building relationships. It was important that he understood their perspectives on the issues and would give them the opportunity to express their views and needs. His approach was thoughtful and personal. This bill was met with much opposition and it took great skill and tenacity on Lincoln’s part to insure its passage. Many Presidents since Lincoln have also faced challenges when trying to pass  legislature, among them our current President Barack Obama. Whether or not you are a supporter of our current President aside, some similarities can be seen between the two. As was the case with Lincoln, Obama is known for his listening skills, and taking in ideas from all sides. He is a skilled orator and there is a strong sense of morality in his tone when speaking. There are many references to President Lincoln in Obama’s speeches which show the influence the former President has on him. Abraham Lincoln led our nation through one of its most turbulent times. He used his communication skills and understanding of people to obtain success. His ability to talk to people and understand what they stood for while moving them to see things his way led him to be regarded as one of our greatest Presidents. References A-E Networks.
