Extract of sample "Item Analysis and Marks"

Item Analysis and Marks Item analysis refers to a group of procedures that are used in the assessment of the quality of exam items. There are two types of item analysis: qualitative and quantitative item analysis. Qualitative item analysis procedures include the careful proofreading of the exam to identify typographical errors, grammatical cues and for appropriateness of the reading level of the material before administration. Qualitative item analysis includes a thorough analysis that uses three numerical indicators: item difficulty, item discrimination and distractor power statistics (Kubiszyn & Borich, 2010). The two item analysis procedures are beneficial to learning and assessment because they help improve the quality of an exam by identifying items that prepare candidates for retention, revision or removal. Item analysis identifies both good and deficient items and clarifies concepts that the examinees have not mastered (Kubiszyn & Borich, 2010).
The risks that come if these items are not administered are that the wrong impression will be got of the student that is not true. Students may fail because there were errors that gave rise to multiple interpretations and not that they did not know. An example of imperfect test may be for example: who was the President of America between 2000 and 2008? A second one may be: Assess the importance of not examining students after end of the course. It is important for the teacher to use both qualitative item analysis and quantitative item analysis because they help to fine tune a test and build reliability and credibility into a test. When we look at qualitative analysis we find that it is subjective as opposed to quantitative analysis and therefore a combination is important to eliminate errors and build credibility into the test (J., 2009).
The authors say that marks reflect only academic achievement and not other factors like attitude and effort because of many reasons. One is that factors like attitudes and effort cannot be graded in terms of marks and therefore it would be difficult to rate a student at the end of the learning period. Secondly students come to school to gain knowledge in a specific field and they are subjected to a syllabus and content that thy must cover in order to show their understanding of various aspects of the course. Their understanding of the knowledge covered in the syllabus can only be done by giving them a test to using marks to gauge their achievement (Kubiszyn & Borich, 2010). Unfortunately attitudes and efforts do not compose the content of the syllabus because of the difficulty in assessing them. Third factors like attitudes and effort are subjective such that various teachers will give varied information about the students’ efforts and attitudes and thus will lead to confusion in giving the overall image of the students’ achievements. Marks make it very easy to rate students as they are objective (Kubiszyn & Borich, 2010).
The incorporation of these factors into the marking data will affect instructional decisions that need to be made simply because the modes of instructions will need to be changed. The current ones only reflect or help in ensuring that the student will be graded at the end. If efforts and attitudes were included it means that other methods need to be devised both for instructions and for assessment. It is impossible to use the current grading system in rating learners because they do not define what effort and attitude is on the reports and how they can be measured by the teacher (Allen, 2005).

Item Analysis

...Item Analysis When designing a test, quiz or exam, it is necessary that the chosen items help in certain key areas of assessment by providing valid results. The test should be able to reliably measure the ability of the test takers so that there is a possibility of comparison amongst members of a group on the basis of the scores obtained. A test should also allow us to understand the overall performance of the group; and to form training or further assessment decisions on the basis of the trends seen amongst the scores of test takers. Individual items of a test need to help us discriminate between people who have understood the concept and those who have not; while helping us understand the extent to which basis concepts have been learnt...

Economic Analysis on BMW Cars in the US Car Industry

Mini and the 1-series rapidly grew at a much higher rate through 2008. Since the early days of the new millennium, BMW has been one of the first automakers to utilize flexible factories in which more than one vehicle model could be produced at the same time. This enabled the company to meet shifts in market demand more effectively than BMW’s competitors could. BMW challenges to retain its market position in the international market for luxury cars. Many automakers, such as Hyundai with its Genesis sedan or Nissan's Infiniti brand are increasingly successful in realizing higher margins earned on luxury vehicles. BMW is rated behind luxury brands such as Lexus, Porsche, Mercedes, and Infiniti for these reasons

Personal Choice: A Comparative Analysis

Published in 1915, the poem’s elements of individual freedom and choice owe much to the nation’s foundational thought that can be traced from Thomas Jefferson to the very core of Ralph Waldo Emerson and can even be seen to embody a European existentialistic spirit. Today, Frost’s poem represents us all, whenever we face the diverging paths in our own lives.

The essential symbolism behind The Road Not Taken is the freedom of choice. Frost advances this metaphor by comparing the decision-making process to, “Two roads diverged(ing) in a yellow wood.” It’s notable that Frost uses the ‘roads’ for his symbolic task over the perhaps more clichéd choice of ‘paths&rsqu...

Analysis of Employement Law Cases

For instance, Section 82(1) of the Sex Discrimination Act 1975 provides statutory protection to workers who are working under a contract personally to execute any work or labor. It also covers self-employed people2.

Other statutes, such as the Working Time Regulations 19983 and the National Minimum Wages Act 19984, are appliable to workers, in addition to employees5. Hence, all these rights and protections are available to Fred, even if he were to be deemed a self-employed person.

Analysis of the Oil Industry

In 2001 alone, the US reported earning from the industry close to two hundred billion US dollars. According to a previous study, the middle east tops the list as the largest exporters of crude oil taking over sixty-six percent of the global production of oil. Europe is the least producers of oil taking only two percent of the market share (Green, 4).
According to the American Association of Petroleum Geologists, the major problem facing the industry is lack of workforce and the increase in demand for oil. The report indicated that by 2030, the world’s oil demand is expected to increase from one hundred and three to one hundred and thirty million barrels per day. Natural gas, on the other hand, will expectedly increase t...

Rhetorical Analysis of Obama Inauguration Address

Not only was the Republican regime of the two Bush Presidents now formally over, but for the first time in history an African American man was taking on the highest and most powerful role in America, and arguably also in the modern world. The weight of history on his shoulders was very heavy, and expectations from all around him were impossibly high. He was no doubt well aware that this speech would be broadcast across the world and closely analyzed by supporters, opponents, and other observers, and he very probably had a team of advisors and coaches helping him to get the content and tone just right, trying to meet as many conflicting expectations as possible, without antagonizing rivals or causing alarm. In the end, the speech w...

Analysis of Documentary about Jerusalem

The documentary is historically accurate and generally fair. There is a lot of room for error, but Jennings is careful to present a balanced perspective.

Religion clearly plays a dramatic role in the Middle East. The truth is that nationalism also plays a huge role. The conflict has a long and bloody history and many people have tried and failed to solve it before. Nothing new has happened in the last few years to make it any easier to solve. In fact, some things have gotten quite a bit worse. There is little visionary leadership available on either side. As things stand now, it is unlikely this conflict will be resolved. The two sides are intractably opposed to one other. Furthermore, the Arab world is poorly developed...
