Standardized Testing The Best Tool For Evaluating Student...
In 2200 B.C. Chinese, civil servants were assessed using some of the earliest forms of standardized testing. Men would be tested on everything from archery to rites and ceremonies. The archery test would consist of shooting three arrows into a target and would be graded based on how many landed. Three arrows would equate to an excellent grade, two was good and one was passable. Standardized tests have evolved since the 2200s. Today, standardized testing is used as the main form of assessment for students in the American school system. Children as young as four years old are required to take standardized tests when entering school. Is standardized testing the best tool for assessing student development and teacher competency? There are some that would argue that standardized testing has its place, but there is an overwhelming majority that would disagree. From California to New York, there is evidence against high stakes standardized testing. Students and teachers alike buckle under t he weight of these tests. Who could blame them when the tests determine, not only who is eligible to graduate high school but also which schools will receive the funding they need? Standardized tests may have had their place in the American school system fifty years ago, but today they are outdated, unreliable, and should be abolished as the main form of assessment in the public-school system. Standardized tests are unreliable in many ways. Poor and minority students, for instance, often scoreShow MoreRelatedEvaluation Of A Clinical Evaluation Essay2196 Words à |à 9 PagesWith the continuous changes in healthcare, evaluation of studentsââ¬â¢ clinical knowledge and skills relies on the need for continuous evaluation.

The newspaper has some interesting topics and itââ¬â¢s not a chore to indulge in as sometimes other newspapers are. Currently, the DOW Jones, a huge stock, is almost 21,047 points. That s very close to the current all time high. Eighty - five years ago, it was nothing like this. In the month of June in 1932, the DOW Jones stock fell to an all time low of 770.26 points. This was part of the aftermath of the Great Depression. Herbert Hoover, the president during the theâ⬠¦show more contentâ⬠¦An investor would contribute a small percentage of the amount of money they would need to buy a stock. A stockbroker or a bank would loan a balance on almost no guarantee they would get their money as needed. This posed a problem. Later, when companies needed it the most, the companies realize that people were still not paying off loans as quickly as needed. The banks and stock brokers start ed to lose large sums of money. They were desperately needing more and more money from people who didnââ¬â¢t have what they needed to begin with. The dismal cycle lead to the stock market crash of 1929. From May 1929 to May 1933 Herbert Hoover served one term as the 31st president of the United States. Hoover was a member of the Republican political party. In his election, he won against Al Smith with 444 of the electoral college votes. A few months into his presidency, the Stock Market Crash occurred. Naturally, the United States as a whole started to look to the president and the government agencies for direction. There were many ideas that Hoover had that didnââ¬â¢t provide relief to the civilians during the Great Depression, they actually worsened the crisis. At some points, he rejected bills that would remedy some of the country s problems, because he believed that the government should not play a huge part in the bettering of the country. This belief was called laissez- faire. (Herbert Hoover) When the stock market crashed, many people were affected. Anyone who had money in the
Absolute Advantage Versus Comparative Advantage - Free Solution
Question: Describe about the Absolute Advantage Versus Comparative Advantage? Answer: On a Valentines Day greeting cards and roses become necessary commodities. The demand for both the goods rises followed by the rise in price. The price of roses always increases more than the price of cards because of price elasticities. The supply elasticity of greetings card on Valentines Day is more elastic than the supply of roses. This is because manufacturers of greetings card can easily increase its production and stock up greetings card. Thus, the supply of cards is relatively elastic. But roses are perishable and are costly enough to increase its supply just for the Valentines Day. This is why the supply is relatively inelastic. (Png et al., 2008) The government imposes a price ceiling of $11 per dozen roses. Price ceiling is the maximum price that the seller can sell to the buyers. The price ceiling provides gains for buyers but some loss is involved for the sellers. (Objectives for Chapter 8 Price Floors and Ceilings, 2015) The gap between the demand and supply causes a shortage of roses. If monitored properly, then this law can be effective to maintain a reasonable price. 2: In consumer behavior what appears to be an irrational behavior to the outsider may be a rational behavior to the individual himself. In this case, the student who was engaging himself in drinking, a day before his exams may seem to be an irrational individual. The irrational behavior arises when an individual has inadequate reason to act, suffering from emotional distress or cognitive deficiency or when individuals interest differs from their expectation, when situation is out of control or one may be fearful, nervous or full of stress. Here the student might be nervous or stressful about his exam the next day and hence he is depicting an irrational behavior by intoxication. The professor might find this rational as some belief that relieving stress is important for exams. (Ariely, 2011) The student can behave rationally by exercising certain stress free techniques to release his nervousness. This could be done by eating well, sleeping well, preparing well for the exam, if possible exercise too be stress free. All these can relieve stress and make the student behave rationally. The profit maximizing condition is given by: Where MR= Marginal Revenue and MC= Marginal Cost. Total Revenue, TR= P(Q)*Q TR= [240 0.10*Q]*Q TR= 240*Q 0.10*Q2 Now: MR= 240 - 0.2*Q Now from the maximizing condition 240 0.2*Q = 30 240 30 = 0.2*Q Q*= 1050 The 1050 wave runners will St. Martin Rentals rent per day.

The opportunity cost of producing 1 cup of hot chocolate per hour is 2.66 for Anna. The opportunity of producing 1 cup of hot chocolate per hour is 1.25 for Elsa. The opportunity cost of producing 1 snow cone per hour is 0.375 for Anna. The opportunity cost of producing 1 snow cone per hour is 0.8 for Elsa. Since the opportunity cost of producing 1 cup of hot chocolate for Elsa (1.25) is lower than that of Anna (2.66), Elsa has comparative advantage in producing hot chocolate per hour. And since the opportunity cost for producing 1 snow cone per hour for Anna (0.375) is lower than that of Elsa (0.8), Anna has comparative advantage in producing snow cones per hour. (Absolute Advantage Versus Comparative Advantage, 2015) Hot chocolate Snow cones Anna 15 8 Elsa 32 20 Clearly Elsa has absolute advantage in producing hot chocolate and snow cones. The opportunity cost of producing 1 snow cone per 3 hour is 1.85 for Anna The opportunity cost of producing 1 snow cone per 3 hour is 1.6 for Elsa. Since opportunity cost for Elsa is lower than that of Anna, Elsa has comparative advantage in producing snow cones. The opportunity cost of producing 1 cup of hot chocolate per 3 hour is 0.53 for Anna. The opportunity cost of producing 1 cup of hot chocolate per 3 hour is 0.625 for Elsa. Since opportunity cost for Anna is lower than that of Elsa, Anna has comparative advantage in producing hot chocolate. Anna specializes in hot chocolate and will sell it to Elsa. On the other hand Elsa specializes in snow cones and will sell it to Anna. In this way they will develop trading relationship be better off. 4: Purchasing a Tig Welder would involve an opportunity cost of the spending $90,000 immediately. There will be a loss of annual interest rate on $90,000 which is 0.05*90,000 = $4500. If $90,000 was lent out then $4500 would have been gained. But purchasing this welder would save only $700 in labor costs per year forever which can save a lot of money in the long run. Hence, this investment can be made. By purchasing a three-dimensional printer, $6500 will be incremented in the revenue per year. But by lending $80,000, an interest of (0.05*80,000) $4000 would have been obtained. This interest rate of return is much lower than the incremental revenue. Thus this investment must be made. By lending out $25000, a return of (1.05*25000) $26250 will be earned. But by organizing this six-sigma training, there will be a one time savings of $26000. Hence, it is not advisable to make this investment. By spending $5000, an interest of $250 is lost and by spending $12000 for the next year, $600 is lost. If $17000 were lent out for two years then there would have been a gain of $18700 which is higher than the return from the completion of the six sigma training of $16000 for one time. Thus, this investment must not be made. 5: A fall in the cost of screen manufacturing by 15%, increases the supply. As producers are now able to sell more quantities of good at the same price. The cost reduction also leads to increase in profit. (net, 2015) Uncertainty regarding the nutritional value of drinking carbonated soda reduces the demand for the same at the existing price. The exchange rate of Canadian dollar in terms of US dollar has increased which implies that Depreciation of Canadian dollar had taken place which implies Canada will now import less and export more. Thus a situation of excess supply arises. (CMS Forex, 2015) The popularity gained by the one inexpensive beef brisket had led to increased demand. This increased demand has resulted in increase in price of beef brisket based on The Wall Street Journal. (CAMPOY and KOPPEL, 2015) References Absolute Advantage Versus Comparative Advantage.

Explain Why It Is Impossible to Derive An Analytic Essay Example For Students
Explain Why It Is Impossible to Derive An Analytic Essay al Formula For Valuing AmericanPuts. Explain why it has proved impossible to derive an analytical formula for valuingAmerican Puts, and outline the main techniques that are used to produceapproximate valuations for such securitiesInvesting in stock options is a way used by investors to hedge against risk. Itis simply because all the investors could lose if the option is not exercisedbefore the expiration rate is just the option price (that is the premium) thathe or she has paid earlier. Call options give the investor the right to buy theunderlying stock at the exercise price, X; while the put options give theinvestor the right to sell the underlying security at X. However only Americaoptions can be exercised at any time during the life of the option if the holdersees fit while European options can only be exercised at the expiration rate,and this is the reason why American put options are normally valued higher thanEuropean options. Nonetheless it has been proved by academics that it isimpossible to derive an analytical formula for valuing American put options andthe reason why will be discussed in this paper as well as some main suggestedtechniques that are used to value them. According to Hull, exercising an American put option on a non-dividend-payingstock early if it is sufficiently deeply in the money can be an optimal practice. For example, suppose that the strike price of an American option is $20 and thestock price is virtually zero. By exercising early at this point of time, aninvestor makes an immediate gain of $20. On the contrary, if the investor waits,he might not be able to get as much as $20 gain since negative stock prices areimpossible. Therefore it implies that if the share price was zero, the putwould have reached its highest possible value so the investor should exercisethe option early at this point of time. Additionally, in general, the early exerices of a put option becomes moreattractive as S, the stock price, decreases; as r, the risk-free interest rate,increases; and as , the volatility, decreases. Since the value of a put isalways positive as the worst can happen to it is that it expires worthless sothis can be expressed as where X is the strike price Therefore for an American putwith price P, , must always hold since the investor can execute immediateexercise any time prior to the expiry date. As shown in Figure 1,Here provided that r 0, exercising an American put immediately always seems tobe optimal when the stock price is sufficiently low which means that the valueof the option is X S. The graph representing the value of the put thereforemerges into the puts intrinsic value, X S, for a sufficiently small value ofS which is shown as point A in the graph. When volatility and time toexpiration increase, the value of the put moves in the direction indicated bythe arrows. In other words, according to Cox and Rubinstein, there must always be somecritical value, S`(z), for every time instant z between time t and time T, atwhich the investor will exercise the put option if that critical value, S(z),falls to or below this value (this is when the investor thinks it is the optimaldecision to follow). More importantly, this critical value, S`(z) will dependon the time left to expiry which therefore also implies that S`(z) is actually afunction of the time to expiry. This function is referred to, according toWalker, as the Optimum Exercise Boundary (OEB). .u8fb39267f2737d903ed0255e8e278e4f , .u8fb39267f2737d903ed0255e8e278e4f .postImageUrl , .u8fb39267f2737d903ed0255e8e278e4f .centered-text-area { min-height: 80px; position: relative; } .u8fb39267f2737d903ed0255e8e278e4f , .u8fb39267f2737d903ed0255e8e278e4f:hover , .u8fb39267f2737d903ed0255e8e278e4f:visited , .u8fb39267f2737d903ed0255e8e278e4f:active { border:0!important; } .u8fb39267f2737d903ed0255e8e278e4f .clearfix:after { content: ""; display: table; clear: both; } .u8fb39267f2737d903ed0255e8e278e4f { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u8fb39267f2737d903ed0255e8e278e4f:active , .u8fb39267f2737d903ed0255e8e278e4f:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u8fb39267f2737d903ed0255e8e278e4f .centered-text-area { width: 100%; position: relative ; } .u8fb39267f2737d903ed0255e8e278e4f .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u8fb39267f2737d903ed0255e8e278e4f .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u8fb39267f2737d903ed0255e8e278e4f .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u8fb39267f2737d903ed0255e8e278e4f:hover .ctaButton { background-color: #34495E!important; } .u8fb39267f2737d903ed0255e8e278e4f .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u8fb39267f2737d903ed0255e8e278e4f .u8fb39267f2737d903ed0255e8e278e4f-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u8fb39267f2737d903ed0255e8e278e4f:after { content: ""; display: block; clear: both; } READ: George Orwell Research EssayHowever in order to be able to value an American put option, we need to solvefor the put valuation foundation and then optimum exercise boundary at the sametime. Yet up to now, no one has managed to produce an analytical solution tothis problem so we have to depend on numerical solutions and some techniqueswhich are considered to be good enough for all practical purposes. (Walker,1996)There are basically three main techniques in use for American put optionvaluations, which are known as the Binomial Trees, Finite Difference Methods,and the Analytical Approximations in Option Pricing. These three techniqueswill be discussed in turns as follows. Cox et al claim that a more realistic model for option valuation is one thatassumes stock price movements are composed of a large number of small binomialmovements, which is the so-called Binomial Trees (Hull, p343, 3rd Ed). Binomial trees assume that in each short interval of time, , over the life ofthe option a stock price either moves up from its initial value of S to , ormoves down to . In general, ; 1 and ; 1. The probability of an up movementwill be denoted by thus, the probability for a down movement is . The basicmodel of this simple binomial tree is shown in Figure 2. Furthermore, the risk-neutral valuation principle is also in use when using a binomial tree, whichstates that any security dependent on a stock price can be valued on theassumption that the world is risk neutral. Therefore the risk-free interest rateis the expected return from all traded securities and future cash flows can bevalued by discounting their expected values at the risk-free interest rate. Theparameters p, u, and d must give correct values for the mean and variance ofstock price changes during a time interval of length . By using the binomial tree, options are evaluated by starting at the end of thetree (that is time T) and working backward. The value of the option is known attime T. As a risk-neutral world is being assumed, the value at each node at timeT can be calculated as the expected value at time T discounted at rate r for atime period . Similarly the value at each node at time T can be calculated asthe expected value at time T discounted for a time period at rate r, and so on. When we are dealing with American options, it is necessary to check at eachnode to see if early exercise is optimal rather than holding the option for alonger while. Therefore by working the binomial backward through all the nodes,the value of the option at time zero is obtained. For example, consider a five-month American put option on a non-dividend-payingstock when the stock price is $50, the strike price is $50, the risk-freeinterest rate is 10% per annum, and the volatility is 40% per annum. With ourusual notation, this means that S = 50, X = 50, r = 0.10, = 0.40, and T = 0.4167. Suppose that we break the life of the option into five intervals of length onemonth (= 0.0833 year) for the purposes of constructing a binomial tree. Then =0.0833 and using the formulas,The top value in the tree diagram above shows the stock price at the node whilethe lower one shows the value of the option at the node. The probability of anup movement is always 0.5076; the probability of a down movement is always0.4924. Here the stock price at the jth node (j = 0, 1, , i) at time is calculated as. Also the option prices at the penultimate nodes are calculated from theoption prices at the first final nodes. First we assume no exercise of theoption at the nodes. This means that the option price is calculated as thepresent value of expected option price in time . For example at node E theoption price is calculated as while at node A it is calculated asThen it is possible to check if early exercise of the option isworthwhile. At node E, the option has a value of zero as both the stock priceand strike price are $50. Thus it is best to wait and the correct value at nodeE is $2.66. Yet the option should be exercised at node A if it is reachedbecause the option would be worth $50.00 $39.69 or $10.31, which is obviouslyhigher than $9.90. Options in earlier nodes are calculated in a similar way. .u48a6e2f413b325582bef2fadab37c777 , .u48a6e2f413b325582bef2fadab37c777 .postImageUrl , .u48a6e2f413b325582bef2fadab37c777 .centered-text-area { min-height: 80px; position: relative; } .u48a6e2f413b325582bef2fadab37c777 , .u48a6e2f413b325582bef2fadab37c777:hover , .u48a6e2f413b325582bef2fadab37c777:visited , .u48a6e2f413b325582bef2fadab37c777:active { border:0!important; } .u48a6e2f413b325582bef2fadab37c777 .clearfix:after { content: ""; display: table; clear: both; } .u48a6e2f413b325582bef2fadab37c777 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u48a6e2f413b325582bef2fadab37c777:active , .u48a6e2f413b325582bef2fadab37c777:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u48a6e2f413b325582bef2fadab37c777 .centered-text-area { width: 100%; position: relative ; } .u48a6e2f413b325582bef2fadab37c777 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u48a6e2f413b325582bef2fadab37c777 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u48a6e2f413b325582bef2fadab37c777 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u48a6e2f413b325582bef2fadab37c777:hover .ctaButton { background-color: #34495E!important; } .u48a6e2f413b325582bef2fadab37c777 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u48a6e2f413b325582bef2fadab37c777 .u48a6e2f413b325582bef2fadab37c777-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u48a6e2f413b325582bef2fadab37c777:after { content: ""; display: block; clear: both; } READ: Contrast Of Romeo And Juliet An West Side Story EssayAs we keep on calculating backward, we find the value of the option at theinitial node to be $4.48, which is the numerical estimate for the optionscurrent value. However in practice, a smaller value of would be used by whichthe true value of the option would be $4.29. (Hull, p347, 3rd Ed)The second technique that is commonly used is the so-called Finite DifferenceMethods. These methods value a derivative by solving the differential equationthat the derivative satisfies. The differential equation is converted into aset of difference equations and the difference equations are solved repeatedly. For instance, in order to value an American put option on a non-dividend-payingstock by using this method, the differential equation that the option mustsatisfy isThe Finite Difference Methods are similar to tree approaches inthat the computations work back from the end of the life of the derivative tothe beginning. There are two different methods involved; one is called theExplicit Finite Difference Method and the other is the Implicit FiniteDifference Method. The former is functionally the same as using a trinomialtree. The latter is more complicated but has the advantage that the user doesnot have to take any special precautions to ensure convergence. The maindrawback of these methods is they cannot easily be used in situations where thepay-off from a derivative depends on the past history of the underlying variable. Finally there is also an alternative to the numerical procedures which is knownas a number of analytic approximations to the valuation of American options. The best known of these is a quadratic approximation approach proposed byMacMillan and then extended by Barone-Adesi and Whalley. This method involvesestimating the difference, v, between the European option price and the Americanoption price since v must satisfy the differential equation for both. They thenshow that when an approximation is made, the differential equation can be solvedusing standard methods. The techniques mentioned in this paper are those commonly used in practise. Although they are not perfect, they are still considered good enough forpractical purposes. So far no one has managed to create a direct analyticalvaluation method for valuing American put options.

What Extent Can Virtual Learning Environments Essay Example
What Extent Can Virtual Learning Environments? Essay There has been a significant increase in the number of students enrolled in universities in the United Kingdom over the last two decades (Saunders and Gale, 2012:847). With a larger number of students, this results in larger class sizes in many institutions. Larger classes with traditional face-to-face teaching may not be efficient enough for students to obtain sufficient knowledge. A solution to this problem is the use of virtual learning environments (VLEs). Shea and Bidjerano (2010, cited in Matzat, 2013:40) stated that online and blended learning is likely to become an important part of the educational system. According to Zhang and Xie (2012:2236), nowadays, technology has developed to such a stage where high speed internet and broadband networks allow the access of actual laboratory resources. This will allow students to access laboratory tools and high performance software from their homes. Reid (2001, cited in Khorsandi et al, 2012:481) reported that there have also been the development and use of online faculty evaluations for students. Virtual learning environments, as defined by Leese (2009:72), are described as an environment which is computer-based and involves the sharing of information between learners and tutors. This essay will assert that using VLEs in an efficient manner can help improve the learning experiences of the student and also encourage behavior of students to take part in and out of class activities. The first part of this essay will look at the positive aspects of VLEs starting with how they are beneficial to students and teachers, then how VLEs encourage students to engage with in and out of class activities, and lastly how VLEs can be used to modify and enhance traditional face-to-face teaching in higher education. To begin with, there are many benefits that both students and teachers can gain from using VLEs.

In a study by Saunders and Gale (2012:857), 90 % of students found that access to course materials through the use of VLEs was ranked highly for enhancing the learning experience. The reason for this was because VLEs allowed all students to gain access to the course material flexibly even in large classes. Furthermore students who missed the lecture could also review their class materials and test their understanding. In another study by Lonn and Teasley (2009:91), the findings report that students find podcast material to be beneficial to their studying. Podcast materials are used for reviewing concepts and issues that were presented in lectures. Once again, for students who missed some lectures they could still acquire the knowledge, issues and concepts that were presented in class. At the end of a course, VLEs can still be used for gathering teaching evaluations. From Khorasandi et al (2012:483), the results showed that students preferred performing evaluations online. Two of the main reasons why the students preferred online evaluations were because of anonymity and privacy. Apparently, it can be seen that VLEs benefit both students and teachers because it allows flexibility for students to access materials and allowing privacy and anonymity in performing evaluations. According to Leese (2009), it has become important that students need to develop certain skills in order to succeed in higher education. The objective of the study was to encourage student engagement in and out of class activities in order to obtain certain skills through the use of VLEs. At the end of the study, students commented that they were able to acquire a number of skills including using technology, teamwork, and presentations. Zhang and Xie (2012:2236) also reported that VLE helped students engage in investigation of authentic problems. Through the use of high speed internet, students could access laboratory tools and high performance software which aid their out of class assignments. Seemingly, it can be seen that technology and the internet can encourage behavior of student to engage in and out of class activities. As living in the 21st century the internet performs a considerable role. Supposedly, it is able to provide access to many resources from serious educational knowledge to humorous entertainment; it can change and enhance traditional face-to-face teaching in so many ways. With the help of VLEs course materials can be accessed easily and students can always review materials through podcasts, it is time for instructors to change their teaching styles not only improve the performance of students in and out of class but also get higher outcomes . From Heaton-Shresthaââ¬â¢s et al (2005:383) study, the staff reported that VLE had an impact on their teaching processes. Some staff had to change the way materials were prepared and designed moreover, how feedback was assessed and given to their students. According to Lonn and Teasley (2009:92), podcasting can allow instructors to focus on the main concepts and devote the time to other teaching strategies. With more time available, instructors are able to devote more time into face-to-face discussions and other innovative activities. With some changes add on the traditional face-to-face teaching, learning experience of students can be greatly enhanced. In conclusion, the essay has shown that VLEs can improve student engagement and performance. Used in an efficient manner, it can help improve the learning experiences of the students and also encourage students to perform better with in and out of class activities. Nevertheless, VLEs may not be able to replace the face-to-face lectures but when it is used in an efficient manner, VLE enhances the studentsââ¬â¢ learning. Students have found VLEs useful for downloading course materials and accessing multiple choice quizzes and case studies. Furthermore, students are able to acquire a number of skills through VLEs such as teamwork, presentation skills and also development in process of learning. While there are many factors that affect student interactions with VLEs, it can be said that VLEs greatly enhance the studentsââ¬â¢ learning experience in higher education. It is also important to know that with the aid of VLEs, the traditional face-to-face teaching must be modified. In future, instructors must change their teaching styles from merely lectures to student-centered approaches and create better environments for a wide variety of learning opportunities as a whole.

ACT Question of the Day Complete Guide
ACT Question of the Day Complete Guide SAT / ACT Prep Online Guides and Tips Are you studying for the ACT? One great way to add some extra prep to your day is with ACT Questions of the Day. They are a fast and easy way to get in some additional prep and figure out where your strengths and weaknesses lie. Read on to find out where you can get the best ACT Questions of the Day, and how to use them most effectively to maximize your ACT score. Where to get the Best ACT Questions of the Day (QOTD) Online The best ACT QOTD can be found on the official ACT site. Every day they present a new question with a detailed explanation of the correct answer. Hereââ¬â¢s an example of an official QOTD grammar question embedded within a larger passage. You can also find decent quality questions here. This site also gives you an explanation of the correct answer, though itââ¬â¢s not always as detailed as the explanations of the official QOTD. The following is an algebra Question of the Day. On your Smartphone You can conveniently access ACT test prep materials on your phone. For Android users, download the ACT QOTD app here. This app makes it easy to access ACT questions anywhere at any time, and it lets you save your answers and look back at any previous ACT questions you may have missed. For iPhone users, you can download the free ACT Student App. While this app is more geared towards general practice than QOTD, you can use it to answer practice questions and learn vocab words. As you can see, itââ¬â¢s as easy to access QOTD as it is to add an extra ACT prep question to your daily routine. So how can adding a question a day help you prepare for the ACT? How to Prep Effectively with QOTD One question a day may not seem like it could accomplish that much, and itââ¬â¢s definitely not a replacement for more extensive study. However, it can be very effective in exposing you to a great variety of ACT questions. ACT Question of the Day involves all types of questions, including English, Math, Reading, and Science (but excludes Writing), so you can get a sense of what you know well and what you need to study up on. Maybe an algebra question is a breeze for you, but coordinate geometry leaves you feeling lost? Mark down any difficult questions or mistakes in your notebook, and use this discovery as a launching off point to overcome your weaknesses. Even if you got the answer correct, make sure you understand exactly why you got it right and can confidently answer similar types of questions that test the same skill. By understanding your answers and analyzing your mistakes, youââ¬â¢ll be able to figure out your strengths and weaknesses and customize your ACT study plan so itââ¬â¢s most effective for you. Start early - even months ahead of your test date. This will ensure you get exposed to the most variety of questions. Always set aside time to do them as a daily habit - if they start to pile up and get backlogged, thereââ¬â¢s not a big chance youââ¬â¢ll have time to go back to them in your busy schedule! ACT QOTD are most effective when they are just that - questions of the day, every day. A Few Limitations of ACT QOTD One limitation of ACT Question of the Day is that you canââ¬â¢t choose the difficulty level of the questions, easy, medium, or hard. However, you can try to determine the difficulty level on your own, as part of analyzing your strengths and weaknesses and figuring out where you need the most practice. You also can't select questions by subject - you can't get an ACT Math Question of the Day, for example. If you ignore your strengths and weaknesses across subjects - and within a subject - you won't make as much progress. Unlike practice tests, QOTD are a quick injection of test prep to your day - they are not helpful for understanding the timing and pacing of the test, or how to keep up your stamina and focus. Taking a practice test under simulated testing conditions is best for that. Finally, they are not helpful for practicing for the ACT essay, if youââ¬â¢re taking the ACT Plus Writing. To Sum Upâ⬠¦ ACT QOTD are effective for preparing you for the ACT a little everyday, as well as allowing you to encounter a variety of questions and figure out your strengths and weaknesses. They are fast and convenient, though not a replacement for your general ACT prep. Start early and youââ¬â¢ll be familiar with the types of questions on the ACT by the time you take the real test! Whatââ¬â¢s Next? To best prep for the ACT, you need official ACT practice tests and strategies for effective studying. Youââ¬â¢re in luck! Check out our free ACT practice tests and learn how to use them to maximize your score. Aiming for that top composite score of 36? We have a comprehensive guide for how to achieve your perfect score by a 36 full scorer. Read about what he did to prep and how you can use the same approach.
