Abstract Common student errors and misconceptions can be addressed through the method of classroom voting, in which the instructor presents a multiple-choice question to the class, and after a few minutes for consideration and small-group discussion, each student votes on the correct answer, using a clicker or a phone. If a large number of students have voted for one particular incorrect answer, the instructor can recognize and address the issue. In order to identify multiple-choice questions that are especially effective at provoking common errors and misconceptions, we recorded the percentages of students voting for each option on each question used in 25 sections of integral calculus, taught by 7 instructors, at 4 institutions, over the course of 12 years, on a collection of 172 questions. We restricted our analysis to the 115 questions which were voted on by at least 5 different classes. We present the six questions that caused the largest percentages of students to vote for a particular incorrect answer, discuss how we used these questions in the classroom, and examine the common features of these questions. Further, we look for correlations between question characteristics and the mean percentage of students voting for common errors on these questions, and we find that questions based on general cases have higher percentages of students voting for common errors.

In order to alleviate the burden for the time-consuming and tedious tasks to make multiple choice questions, we proposed the system that generates multiple choice questions from the sentence with multiple component keywords and then relocates the questions selected by an array with random numbers instead of random functions in order to reduce the relocation time, after the system searches for the group of informative sentence with multiple component keywords by using special idioms. In this paper, the idiom is the CRm type idiom that has several components at the right side of this idiom including in a main informative sentence. The next sentences consist of other informative sentences including the components keywords. To make multiple choice questions, the system randomly selects an informative sentence including a component keyword and it also converts the informative sentence into a question. The selected component keyword is used as the correct answer and the three other component keywords are used as distractors. To produce many different questions about the same contents with different positions of the question and items, the system uses a random number array to reduce the relocation time.

<p class="abstract"><strong>Background:</strong> Multiple choice questions (MCQs) are routinely used for formative and summative assessment in medical education. Item analysis is a process of post validation of MCQ tests, whereby items are analyzed for difficulty index, discrimination index and distractor efficiency, to obtain a range of items of varying difficulty and discrimination indices. This study was done to understand the process of item analysis and analyze MCQ test so that a valid and reliable MCQ bank in otorhinolaryngology is developed.</p><p class="abstract"><strong>Methods:</strong> 158 students of 7<sup>th</sup> Semester were given an 8 item MCQ test. Based on the marks achieved, the high achievers (top 33%, 52 students) and low achievers (bottom 33%, 52 students) were included in the study. The responses were tabulated in Microsoft Excel Sheet and analyzed for difficulty index, discrimination index and distractor efficiency.  </p><p class="abstract"><strong>Results:</strong> The mean (SD) difficulty index (Diff-I) of 8 item test was 61.41% (11.81%). 5 items had a very good difficulty index (41% to 60%), while 3 items were easy (Diff-I &gt;60%). There was no item with Diff-I &lt;30%, i.e. a difficult item, in this test. The mean (SD) discrimination index (DI) of the test was 0.48 (0.15), and all items had very good discrimination indices of more than 0.25. Out of 24 distractors, 6 (25%) were non-functional distractors (NFDs). The mean (SD) distractor efficiency (DE) of the test was 74.62% (23.79%).</p><p class="abstract"><strong>Conclusions:</strong> Item analysis should be an integral and regular activity in each department so that a valid and reliable MCQ question bank is developed.</p>

The Impact

Multiple choice exams are ubiquitous, but advice on test-taking strategies varies and is not always well informed by research. This study evaluated the question of whether students benefit or are harmed when they change their initial answers on multiple choice questions in the context of physiology and biology courses. Previously marked examinations were reviewed for eraser marks that indicated answer changes, and the impact of these changes on exam grades was tabulated. In addition, faculty and students were surveyed for their opinions about changing answers. A plurality of faculty (36%) reported a belief that answer changes usually harm student grades, whereas a slim majority of students (51%) believed that answer changing helped their scores (χ2 = 60.52, P < 0.0001). Empirically, across two exams, students changed their answer from an incorrect answer to a correct one 2.8 times (SD 2.2) compared with 1.0 time (SD 1.4) changing in the negative direction. Therefore, on average, students benefited ( V =  123.5, P < 0.0001) from answer changing. Furthermore, comparing across two exams in the same course, some students were consistently more likely to change their answers than others (adjusted R2= 0.23, P < 0.0001), but the impact of changing answers on the first exam provided no prediction of how much a student would benefit from answer changing on the second exam (adjusted R2= −0.004, P = 0.42). These data support the argument that students should be advised to review and revise responses to exam questions before submitting them.

The Social

This demonstration illustrates principles of group dynamics and dynamic social impact and can be used in classes in social psychology or group dynamics. Students discuss their answers to multiple-choice questions with neighbors and answer them again. Discussion consistently leads to the consolidation (reduced diversity), clustering (spatial-self-organization), correlation (emergent linkages), and continuing diversity of responses. “Truth” does not necessarily win, showing that the social reality of the group may be more important than objective reality.
