Top 8 Reasons Non-Teachers Can Never Understand Our Job
Believe it or not, I once had an older family member approach me at a party and say, ââ¬Å"Oh, I want my son to talk to you about teaching because he wants a career thatââ¬â¢s easy and not stressful.â⬠I donââ¬â¢t even remember my response to this illogical and bizarre comment, but obviously this ladyââ¬â¢s cluelessness made a major impression on me. Iââ¬â¢m still confounded by this idea even ten years after the incident occurred. You may have been on the receiving end of similar comments, such as: Youââ¬â¢re so lucky to have so much vacation time, especially summers off. Teachers have it so easy!You only have 20 students in your class. Thatââ¬â¢s not so bad!It must be so easy to teach elementary school. The children donââ¬â¢t have attitudes when theyââ¬â¢re so young. All of these ignorant and annoying comments just go to show that people who arenââ¬â¢t in education simply canââ¬â¢t understand all of the work that goes into being a classroom teacher. Even many administrators seem to have forgotten about all of the trials and tribulations we face on the front lines of education. Summers Arenââ¬â¢t Enough Recovery Time I do believe that every teacher appreciates our vacation times. However, I know from experience that a summer vacation isnââ¬â¢t nearly enough time to recover (emotionally and physically) from the rigors of a typical school year. Similar to childbirth and moving houses, only time away can offer the necessary respite (and memory failure) that allows us to gather the strength and optimism required to attempt teaching anew in the fall. Besides, summers are shrinking and many teachers use this valuable time to earn advanced degrees and attend training courses. In the Primary Grades, We Deal With Gross Bathroom-related Issues Even a high school teacher could never understand some of the crises related to bodily functions that a typical K-3 teacher has to deal with on a regular basis. Potty accidents (and more instances too disgusting to reiterate here) are something that we canââ¬â¢t shy away from. Iââ¬â¢ve had third grade students who still wear diapers and let me tell you ââ¬â itââ¬â¢s stinky. Is there any amount of money or vacation time worth cleaning up vomit from the classroom floor with your own two hands? Weââ¬â¢re Not Just Teachers The word ââ¬Å"teacherâ⬠just doesnââ¬â¢t cover it. Weââ¬â¢re also nurses, psychologists, recess monitors, social workers, parental counselors, secretaries, copy machine mechanics, and almost literally parents, in some instances, to our students. If youââ¬â¢re in a corporate setting, you can say, ââ¬Å"Thatââ¬â¢s not in my job description.â⬠When youââ¬â¢re a teacher, you have to be ready for everything and anything to be thrown at you on a given day. And thereââ¬â¢s no turning it down. Everythingââ¬â¢s Always Our Fault Parents, principals, and society in general blame teachers for every problem under the sun. We pour our hearts and souls into teaching and 99.99% of teachers are the most generous, ethical, and competent workers you can find. We have the best of intentions in a messed-up education system. But somehow we still get the blame. But we keep teaching and trying to make a difference. Our Job is Really Seriousà When thereââ¬â¢s a mistake or a problem, itââ¬â¢s often heart-breaking and important. In the corporate world, a glitch might mean a spreadsheet needs to be redone or a little money was wasted. But in education, the problems go much deeper: a child lost on a field trip, students lamenting parents in jail, a little girl sexually assaulted on the walk home from school, a boy being raised by his great-grandmother because everyone else in his life abandoned him. These are true stories that Iââ¬â¢ve had to witness. The pure human pain gets to you after awhile, especially if youââ¬â¢re a teacher out to fix everything. We canââ¬â¢t fix everything and that makes the problems we witness hurt all the more. Work Outside the School Day Sure, school only lasts 5-6 hours per day. But thatââ¬â¢s all weââ¬â¢re paid for and the job is constant. Our homes are cluttered with work and we stay up til all hours grading papers and preparing for future lessons. Many of us take phone calls and emails from parents during our ââ¬Å"personalâ⬠time. The problems of the day weigh heavy on our minds all night and all weekend. Zero Flexibility When Youââ¬â¢re a Classroom Teacher When you work in an office, you can simply call in sick when you wake up unexpectedly ill on a given morning. But, itââ¬â¢s extremely hard to be absent from work when you are a teacher, especially if it happens without notice or at the last minute. It can take several hours to prepare the lesson plans for a substitute teacher which hardly seems worth it when youââ¬â¢re only going to be absent for five or six hours of classroom time. You might as well just go teach the class yourself, right? And dont forget the last one... Teaching is Physically and Emotionally Taxing To put it bluntly: Since bathroom breaks are hard to come by, itââ¬â¢s said that teachers have the highest incidences of urinary and colon problems. There are also issues with varicose veins from having to stand all day. Plus, all of the above difficulty factors, combined with the isolated nature of being the only adult in a self-contained classroom, make the job especially grueling over the long term. So for all you non-teachers out there, keep these factors in mind the next time you envy a teacher for her summers off or feel the urge to say something about teachers having it easy. There are some things about the profession that only teachers can understand, but hopefully this little gripe session has shed some light on the true nature of the job! And now that weââ¬â¢ve got most of the complaints out of the way, keep an eye out for a future article that will celebrate the positive side of teaching!

Environmental Benefits Of Wind Energy Essay - 1216 Words
For years the United States has been one of the leading countries in greenhouse gas emissions. Wind energy has the potential to become the base of sustainable energy for Americaââ¬â¢s future. Although there are a few disadvantages to wind energy, the protection it offers along with the economical and environmental advantages provide many reasons to use more wind energy and less coal and fossil fuels in America. Wind energy can build a safeguard for the United States to protect us from outside adversity and harm. Increasing the number of wind turbines will help the country become less energy dependent. In 2015, the United States imported over 2.5 million barrels of crude oil from the Organization of Petroleum Exporting Countries alone (Wind Vision). Because this group is responsible for over two thirds of the countryââ¬â¢s oil imports, This orginiation could sharply increase or decrease the price of oil in America by raising or lowering the price per barrel of crude oil. By introducing more wind energy into the United States we lower our dependence on other countries to provide us with the resources we need to create electricity. Along with the United States becoming less dependent on other countries, America would find itself less susceptible to an increase in the prices of resources due to lack of fossil fuels (Wind Vision). Wind energy acts as a safeguard and stabilizer for any p roblems that may arise with more common forms of energy, namely coal and fossil fuel, both ofShow MoreRelatedClimate Change And The United States928 Words à |à 4 PagesOne of the great parts about wind energy is that it has a large amount of positives to the environment and hardly any negative effects. Because wind energy uses the wind for the energy there is no emissions generated from the energy produced. It is estimated that the use of one million kWh of wind power can save around 600 tons of carbon dioxide emissions (Saidur, Rahim, Islam, Solangi, 2011).

A Research Study On Ivf - 890 Words
Before this systematic review published, only two reviews were available of outcomes for singletons after IVF techniques. In comparison with natural conception, it has been proposed that the obstetric results of pregnancies are poorer with IVF/ICSI. Today, it is reported that the number of women that undergo IVF/ICSI process is increasing around the world. With this, I am curious about the risks for women having IVF/ICSI and how perilous it is to them since the process is not natural. I would also like to know what causes the risks and specifically the factors that increase them. As a nurse who had IVF education and practice and worked with such renowned IVF specialists such as Dr. Buckett, Dr. Holzer and Dr.Tan, I decided to conduct a synthesized evidence search on the systematic review so that I can help these patients to have more attentive care to prevent or minimize the possible risks of In Vitro Fertilization techniques that may potentially endanger them. In this synthesized, evidenced search, I wanted to learn whether IVF pregnancies are bound to greater precarious risks and whether there is the way to minimize possible risks by providing more antenatal care to the clients. I find this important since most of the patients having IVF/ICSI are very delicate, so they would require more systematic care based on recent studies. I used the key search terms.

International Trade and Trade Restrictions free essay sample
Trade restrictions can be in the form of tariffs, which are taxes on imports; quotas, which are limits on the quantity of a particular good that can be imported or exported; or other trade restrictions. International trade efficiencies, trade restrictions, and the consequences of these restrictions will be discussed further. World trade offers many advantages to the trading countries: access to markets around the world, lower cost through economies of scale, the opportunity to utilize abundant resources, better access to information about markets and technology, improved quality honed by competitive pressure, and lower prices for consumers (McEachern, 2012, p. 733). Comparative advantage, specialization, and trade allow people to use their scarce resources most efficiently to satisfy their unlimited wants. Comparative Advantage is the ability to make something at a lower opportunity cost than other producers face (McEachern, 2012, p. 32). The ability to make a good at a lower opportunity cost gives that individual, firm, region, or country a comparative advantage. Even if a country has absolute advantage in all goods, they should specialize in producing the goods in which it has a comparative advantage. If each country specializes and trades according to the law of comparative advantage, everyone would benefit from greater consumption possibilities. McEachern provides three reasons for international specialization: countries having different resource endowments, greater economies of scale can be achieved when firms participate in international trade, and tastes differ from country to country (McEachern, 2013, p. 719-720). Every country has a comparative advantage in the production of some products. This means that the labor and capital resources available in the reason are more productive when focused towards a particular industry and thus are able to be produce that product better as a result. In the case of the textile industry, Pakistan enjoys a comparative advantage as it has many cotton fields, providing it direct access to the raw material for the industry. It further has been operating in that industry for a long time that has spawned a lot of trained workforce relating to that industry in the country. Therefore, law of comparative advantage dictates that it should produce textile materials. The World Trade Organization (WTO) is the only global international organization dealing with the rules of trade between nations (WTO, 2012). Their goal is to help producers of goods and services, exporters, and importers conduct their business. The WTO and agreements such as NAFTA open up free trade, allowing goods to move freely and thereby aiding consumers in various countries in terms of prices and quality. It also spawns healthy competition in the local industries. Trade restrictions can lead to a breakdown in competition and can lead to adverse effects in the local and international market. Restrictions can benefit certain domestic producers that lobby their government for benefits. Congress tends to support the group that fights back, so trade restrictions often persist, despite the clear and widespread gains from freer trade. For example, U. S. growers of sugar cane have been protected from imports, which results in an increase in U. S. sugar prices. Higher prices hurt domestic consumers, but they are usually unaware. As McEachern states, ââ¬Å"Consumers remain largely oblivious. â⬠Who is responsible for trade ethics? Government might be the initial answer but all constituents involved should be aware and be transparent. An example is Nike, Inc. They provid a statement in understanding how to change the way an industry views its labor force. It does not happy by monitoring factories alone. Monitoring reveals the issues, issues that in turn are locked into a complex web of root causes. The ability to address these root causes should be shared by many, owned by no single constituent (Nike, Inc. , 2013, p. 1). One of their strategies is to transform working relationships with their contracted factories to incentivize change that will benefit workers. Are trade restrictions effective? Trade protection can foster inefficiencies. The immediate cost of such restrictions includes not only the welfare loss from higher domestic prices but also the cost of resources used by domestic producer groups to secure the favored protection (McEachern, 2012, p. 732). These costs may become permanent if the industry never realizes the economies of scale and never becomes competitive. Protecting one stage of production usually requires protecting downstream stages of production as well. The biggest problem with imposing trade restrictions are that other countries usually retaliate which shrinks the gains from trade. Some experts believe the costs of protecting the jobs of workers in vulnerable industries, which are ultimately borne by taxpayers or consumers, far exceed the potential cost of retraining and finding new jobs for those workers (Globalization 101, 202, para. 1). In addition, that it may not promote firms and industries to make necessary changes to challenge foreign competition and find efficiencies to which then would make them become even more dependent on government protection. As international trade has increased, conflicts over trade have also increased. Trade restrictions may continue to be very political in nature. The more companies like Nike and consumers start being more aware of ethical behavior around international trade, the more everyone will benefit. The U. S. government does take responsibility for workers who lose their jobs by international trade and have programs established to assist in training and support to re-employ those workers. As countries specialize and trade according to the law of comparative advantage, consumers should also benefit from efficient production and cheaper prices. The increase of technology may have an impact that will increase the speed at which international trade and efficiencies happen. References McEachern, W. A. (2012). Economics, 9e (9th ed).

Physics IA bouncing ball Essay Example
Physics IA bouncing ball Paper 1. Put the ruler perpendicular to the flat surface.Ã 2. Place the ruler in the arm of the metal stand and secure it tight so that the ruler can stay still; it must be perpendicular to the surface and parallel to the stand.Ã 3. Grab the rubber ball and place it with one hand besides the 10cm mark in the ruler.Ã 4. With the other hand have the chronometer in 0 seconds and be ready because as you are going to release the ball you have to start the count in the chronometer.Ã 5. Drop the ball and start the count in the chronometer simultaneously. 6. Wait until the ball to stop bouncing completely, this is, wait for the ball to start rolling so that you can see movement just in the horizontal way or x-axis and not in the vertical way or y-axis, and in that specific time, stop the count.Ã 7. In your physics lab table write the resultant time t for the height h of 10cm.Ã 8. Repeat steps 3-6 twice and write the multiple resultant times in your physics lab table in order to have three time samples. This is for avoiding random errors.Ã 9. Continue the pattern of releasing the ball from each multiple of 10 until reaching 100cm, measuring three times from each multiple of 10cm. Write the results in your physics lab table.

Calculate the average of the three times you measure for each multiple of 10cm to 100cm by using this formula:Ã Taverage= (T1+T2+T3)/3Ã and write it in your physics lab table in an extra column.Ã For more accurate results:Ã -Do not move the experiment while taking your measurements. If you change the place of the experiment, the surface texture, evenness, or slope may change as well, making the results less accurate.Ã -Use the SAME ball throughout all the experiment; each ball has in general the same characteristics, except that they usually are not perfectly round and they have different sizes and masses. By using the same ball you are increasing accuracy in your measurements. Uncerntanties The uncertainty of the dependant variable, which is the time t, is 0.35 s. This has been measured by subtracting the smallest value to the greatest value of time in every measurement of the height, and then the result of that was divided by 2. It can be better explained with this equation:Ã After that, the greatest difference of all the results is going to be the one that is chosen to be the uncertainty of time in every measure of height. In this experiment the greatest difference was found in the value of height 80cm, which was 0.35 because. Therefore, 3.5 is going to be the uncertainty of time. All values of time have been rounded to 0.10cm.Ã The uncertainty of the independent variable, which is the height h, is 0.1cm. This has been settled without any formal guidelines; the factor that just the human eye is used for this experiment and no other more accurate mechanism, gives an uncertainty because the human being is not perfect when measuring something. In this case, the hand can shake at the point of the ruler, or just the perspective of the experimenter can create some error coefficient when measuring the height using a ruler. All values of height have been rounded to 0.1cm.Ã The following graph was made with Logger Pro Software. I included the uncertainty bars and the computer generated the best straight line and determined the gradient.Ã Now, the graph is repeated with maximum and minimum gradients based on the extremes of the first and last data point uncertainty bars. Conclusion and Evaluation In Figure 1.3, which is the first graph of our results, there seems to be a direct relationship between the increase of time and the increase of height in the experiment. The straight line that the computer generated shows an increase in both x and y axes which represent the height and the time, respectively.Ã I can conclude by saying that the experiment of releasing a ball at certain heights, that in this case they were from 10cm in multiples of 10 till reaching a meter, and measuring multiple times to get an average, that in this case was measuring 3 times per measure of height the time it took for the ball to stop bouncing completely and then making a average time, that the hypothesis of height being proportional to time was right and has been proved by analyzing the results and graphs. Time t and the height h were proportional to each other because in the result graph we find a straight line with a slope that proves that proportionality. This makes the experiment successful because the objective of proving the hypothesis was achieved.Ã After analyzing these factors, the answer to the question How does altering the height when releasing a bouncing rubber ball affect the time until its complete rest in the vertical sense or y-axis? is that as the height increases where the ball is released, it is going to take more time until its rest in the vertical sense, and in the other hand, as the height decreases, the ball is going to take less time to stop bouncing. Problems and Improvement Originally, the experiment was meant to measure the time until the ball reached complete rest (in both x and y axes) so that it could be easy to stop the chronometer and be more accurate. The problem was that the ball would roll on the floor, and as the floor is an even texture, the ball would stop completely taking a lot of time doing it, and sometimes the time it would take to stop in some cases would be very different to other cases because the ball rolls in different directions every time. Changing the experiment of measuring the time until the ball achieved complete rest to measuring time till the ball achieved complete rest in the vertical sense or the y-axis was the solution to overcome this problem. It created a minor problem though. The problem is that the eye cant really see when the ball stops bouncing completely because there are some bounces in the y-axis that cannot be seen by the human eye because they are really minor, making the stopping of the chronometer count a little subjective and decreasing the accuracy of the experiment.
