Cheating in Education Today

On the last day of the term, I needed to grade a set of papers while my class was taking the same test in order to distribute exam waivers by the end of the day. Suspecting that students coming to my desk might accidentally see answers on the key for the one multiple choice page, I coded the answers on my answer key the multiple choice responses so that I AB, BC and so on and proceeded to grade papers. My suspicions were correct: Of the fifteen or so students in the room, six came to my desk once or twice, returning to his seat with a smug smile. I felt a twinge of guilt as I watched them quickly scribbling answers, considering the situation had a flavor of entrapment, but decided these students might learn an unexpected lesson. The slickness of their moves was dismaying, but I felt worse seeing which students were cheating-- only those I had held in highest regard. When all papers finally were in, I said I had bad news for all those people who had cheated. Innocent cries of Who cheated, ensued, loudest from those who had. But they ceased when I said the cheaters had reproduced a perfect pattern of wrong answers. I had believed cheating in my classes was tightly controlled. I rarely gave credit for rechecked answers, I kept assignments until students can no longer get credit for turning in copied work, and I rarely gave multiple choice tests. Nevertheless, during final exam week I found a little crib sheet stuck on a shelf and another lying on the floor. Perhaps more telling, a few students who rarely complete their work left the room once they realized cheating on the essay exam would be impossible. Apparently, their experience had given them confidence that they can get away with cheating. I wondered if this confidence made studying seem a waste of time. A Nationwide Problem Survey results about the prevalence of cheating in high school taken by Whos Who Among American High School Students in 1993 revealed that an alarming 89% of high school students thought cheating was common and 78% had cheated.It seems logical to assume that successful cheating in high school inspires cheating at the college level, for surveys taken in 1990 indicate as many as 45% college students cheated in one or two courses and 33%, in eight or more courses. The problem, however, is not just with the students themselves, in a recent U.S. News Poll 20% of adults felt there was nothing wrong with parents completing their childs homework. Resources That Help Detect Cheating and Plagiarism While, discouragingly, there are many internet sites that give examples of slick cheating techniques and sell pre-written term papers, there are many other online resources to help teachers catch cheaters. One of the best is Grammerly, which has a plagiarism checker as well as providing strong grammar checking tools.

The Media Of Body Image - 2000 Words

Once upon a time, you probably liked your body and appreciated the many things it could do, but the route to adulthood, doubts and insecurities may have crept in. The images the media exposures the society to are of thin and beautiful women and extremely muscular men.

Database Optimization Saving Time and CPU Usage Essay

Database optimization is something, that while may go unnoticed, is very important a very important for saving time and CPU usage. In attempting queries on the math database downloaded form stackexchange. A query is an expression written in a programming language, in this case SQL, that is used for data look up in a database. Stackexchange is a large compressed file that contains a record of all the forums from the website I specifically used the math files since they are one of the largest files in size and serve as a perfect example for why database optimization, and finding efficient SQL queries is important. I have noticed that complicated queries can be optimized to make for faster, more complete results. With the†¦show more content†¦( Query Optimization in Database Systems) To sum it up query optimization is important so that these costs can be reduced as much as possible even as the amount of data increases. Using the schema: users id integer, name text, rep, integer, about text) posts( id integer, title text, owner_id text, post_id, created text) com(comment_id integer, post_id integer, comment_text text, user_id integer), I ran a query â€Å"SELECT COUNT(post_id), created FROM posts GROUP BY created† to get a count of how many posts were made and on what days. This took anywhere from five to ten seconds to run which is a pretty good amount of time. The problem with the query is that it is too simple. Every time it is run it is searching the entire database and printing everything out. For one thing this is not ideal since it is not very readable and the information is not very specific. To make this query better I added on â€Å"WHERE† clauses to give it a specific target. If looking for a how many posts where created on 2010-03-27 14:53:20.727 then run query â€Å"SELECT count(post_id) FROM posts WHERE created = 2010-03-27 14:53:20.727.

Impacts of Automatic Cars

Question: Explain about the how automatic cars have affected the financial structure of the country but it has some good impacts on the society as well. Answer: Introduction: Two organizations have merged together and implemented a new innovative car which is to be operated without drivers. Google has developed a robotic programming and has implemented this as futuristic driver less cars. The organization has taken the full responsibility of the passengers. It has been observed that it is white technology that has supported such an auto pilot system and has increased the awareness of the drivers in controlling the vehicle in emergency situation (Stanton, 2015). The organization has not changed the basic design of the cars such as steering wheel, pedals, clutch and break. The organization has named the new vehicle Catch 22 (Litman, 2014). The organization has already implemented driverless cars and is continuing the research process. The organization expects that this product will be released in the market within a couple of years . Main body: Article 1: It has been observed the utopian vision of the motor vehicle has helped the organization in implementing the auto driving facility in the cars. Therefore, the drivers can work or take rest while driving the cars. The organization has claimed that it is the highest technological achievements till now (Fagnant Kockelman, 2014). However, the organization has not changed the basic settings of the mechanical parts of the cars because with these the drivers can control the vehicle in case of an emergency. The necessary parts of the cars such as steering wheel, pedal, clutch and break remain same so that the drivers can drive the cars smoothly. The organization has renamed this as Catch 22 (Burns, 2013). The organization has claimed that the drivers will not require to drive the computer drive cars. As stated by Le, Zolfaghari and Polak (2015), sometimes the computer driven cars are reliable but the reliability cannot be guaranteed. As argued by Verberne, Ham and Midden (2012), the drivers can understand the road conditions better than the programmers and engineers. It has been observed that customers are often facing regarding reading, working, internet and email usage and other such facilities in these driverless cars. However, nobody is aware about the facilities of these driverless cars (Merat et al., 2012). According to the 20 Years research report it has been found that drivers are far more necessary than an automatic system(Firnkorn Mller, 2015). As stated by Firnkorn and Mller (2015), the human drivers fail to intervene when these automatic driving systems. According to Litman, (2014), the organization needs to develop a new system which delivers continuous information to the drivers. On the other hand, it has been found the automated braking system is 5 times slower than the manual braking system (Firnkorn Mller, 2015). The organization has observed such robotic cars reduce the responsibility of the drivers as they have little or no control on the vehicle. Article 2: Google has already released footage of the prototype of the driverless cars. On the other hand, the organization has already influenced people about the potential of the self-driving cars. This idea may not be new, but the implemented excellent technological innovation is. It has been observed that large car manufacturers have already installed the old 1920s autonomous car programming system named as magic highway (, 2014). Customers seem to extremely be confused about their choice because most of the cars have a bad impact on the environment. It is understood that often such specific cars face difficulty in sustaining themselves in the market due to the presence of stiff competition. As stated by Verberne, Ham and Midden (2012), customers seem to be perplexed about more than one million car models present in the market (Firnkorn Mller, 2015). The numbers of car owners have increased in the rapidly developing economical countries such as Brazil, China and India (M erat et al., 2012). Moreover an increase in emissions has also resulted in the oil crisis and loss of sustainability. Therefore, it has been observed that such a disruptive trend cannot be sustained for long term without compromising on future generations. It has been observed that companies have implemented electric cars to decrease the dependency on fuel. As stated by Verberne, Ham and Midden (2012), the manufacturers have implemented various electric operated vehicles to the market. However, maximum customers prefer fuel powered vehicles to electric cars (Firnkorn Mller, 2015). Therefore the electric cars cannot be considered as a substitute for the fuel cars. As argued by Le, Zolfaghari and Polak (2015), the self driven cars are safe for the people who cycle or walk on the road. It has been observed that self driven cars have been programmed to avoid any kind of obstacles. Google on the other hand has decided to implement the self driven cars as a replacement for the taxi (Firnkorn Mller, 2015). The organization is hopeful that the cars will beneficial for short distances. The driverless cars also require a strong internet connection. It has been observed that more than 87% of people in the UK have a driving license (Firnkorn Mller, 2015). Therefore the self driving cars would not be beneficial for the professional drivers. Article 3: Uber has declared that their autonomous cars will be complete by 2025 and they will finally swap the autonomous cars by 2030 with the normal cars. As stated by Narla (2013), the environmental problem will make a fundamental restructuring economy. It has been observed that Tesla Motors has already implemented the self driven electric cars in 2015 (, 2015). On the other hand the General Motors (GM) has planned to launch their self driven electric cars by 2017 (Firnkorn Mller, 2015). The CEO of GM has remarked that the smart monitoring and controlling system will control the steering, acceleration and breaking in self driving condition. It has been observed that Google and Tesla Motors have planned to implement a fully autonomous car (Merat et al., 2012). It is believed by these organizations that such cars will be publicly available by 2020 (Litman, 2014). According to the experts review, the customers will be slow to purchase the autonomous cars. The organization has observed that the cost of the ownership is nearly $US 9, 000 per year (, 2015). However the automobile industry is hopeful that many people will buy automated cars. On the other hand, the ride sharing service like Uber and Zipcar will gain the popularity as an alternative to car ownership. As stated by Le Vine, Zolfaghari and Polak (2015), the autonomous car movement will reduce the vehicle population by 99%. This may also affect the insurance market, automotive finance market, parking industry and automotive aftermarket. Conclusion: It has been observed that the automated cars have affected the financial structure of the country but it has some good impacts on the society as well. The self driven cars will reduce 90% crashes and save approximately 30,000 lives every year. On the other hand, the automated cars will prevent more than 2.12 million injuries every year. It has been observed that 30% city traffic will reduce. The parking place, bus terminus and garages become obsolete. Therefore ample free space will available for real estate and metropolitan development. Reference list: Burns, L. D. (2013).
