Students often gauge their performance before and after an exam, usually in the form of rough grade estimates or general feelings. Are these estimates accurate? Should they form the basis for decisions about study time, test-taking strategies, revisions, subject mastery, or even general competence? In two studies, undergraduates took a real…

Understanding genetic drift is crucial for a comprehensive understanding of biology, yet it is difficult to learn because it combines the conceptual challenges of both evolution and randomness. To help assess strategies for teaching genetic drift, we have developed and evaluated the Genetic Drift Inventory (GeDI), a concept inventory that measures…

Discusses answer justification, a technique that allows students to convert multiple-choice items perceived to be "tricky" into short-answer essay questions. Convincing justifications earn students credit for missed items. The procedure is reported to be easy to administer and very popular among students. (Author/GEA)

Complex multiple choice (CMC) items are frequently used to test knowledge about repetitive information. In two independent comparisons, performance on the CMC items surpassed that of the multiple true-false clusters. Data indicate that performance on CMC items is inflated, and distractors on CMC items fail to prevent guessing. (Author/PN)

The test-preparation program in this guide covers all forms of test taking to help students deal with real-world problems like test anxiety and insufficient preparation time. The chapters are: (1) "Finding Out about the Tests You Must Take"; (2) "Making a Study Plan"; (3) "Carrying Out Your Study Plan"; (4) "Learning Strategies"; (5) "Coping with…

Examines the conventional scoring formula for multiple-choice tests and proposes an alternative scoring formula which takes into account the situation in which the student does not know the right answer but is able to eliminate one or more of the incorrect alternatives. (Author/AV)

Investigates the circumstances under which answer changing is beneficial or detrimental to test performance. Analyzes the success of answer changing in relation to the reasons offered for changing. Concludes that students who reported guessing as their reason for changing answers were not nearly as likely to benefit from changing as were students…

Undergraduates (N=141) completed different versions of Palmore's Facts on Aging (FAQ) quizzes to test effects of "don't know" (DK) answers. Findings suggest the DK option yields more accurate knowledge scores, eliminates guessing, enhances the use of FAQ as a research instrument and for pre/post evaluation of training in aging.…

Discusses statistical procedures for increasing test unreliability due to guessing in multiple choice and true/false tests. Proposes two new measures of test unreliability: one concerned with resolution of defined levels of knowledge and the other with the probability of examinees being incorrectly ranked. Both models are based on the binomial…

A new scoring procedure for multiple choice tests attempts to assess partial knowledge and to restrict guessing. It is a variant of Coombs' elimination scoring method, adapted for use with the carbon-shield answer sheets commonly used with answer-until-correct scoring. Examinees are directed to erase the carbon shields of choices they are certain…

The effects of option familiarity, length, and technicality on guessing or multiple choice items were investigated in two experiments. Generally, these college undergraduates tended to favor familiar, non-technical, and longer options when guessing on multiple choice tests. (JKS)

Accuracy of students' judgments of learning (JOLs) in predicting recognition versus recall was investigated in 4 experiments involving 263 college students. Accuracy was greater for delayed JOLs than for immediate JOLs, and the accuracy of JOLs was lower in predicting recognition than recall. (SLD)

A statistical test of the knowledge or random guessing model is presented. A version of the model is introduced in which it is assumed that alternatives can be ordered according to a Guttman scale. Three examples illustrate its application to data from a total of 590 college students. (Author/SLD)

The Musical Aptitude Profile (MAP) and four levels of the Iowa Tests of Music Literacy (ITML) were administered to university non-music majors to investigate the use of the "in doubt" test item response. The "in doubt" response was not used indiscriminately by the university students on either test battery. (Author)

Students in an introductory college course (n=275) responded to equivalent 20-item halves of a test under number-right and formula-scoring instructions. Formula scores of those who omitted items overaged about one point lower than their comparable (formula adjusted) scores on the test half administered under number-right instructions. In contrast,…
