A psychological framework for different types of items commonly used with mixed-format exams is proposed. A choice model based on signal detection theory (SDT) is used for multiple-choice (MC) items, whereas an item response theory (IRT) model is used for open-ended (OE) items. The SDT and IRT models are shown to share a common conceptualization…

Large-scale standardized tests are regularly used to measure student achievement overall and for student subgroups. These uses assume tests provide comparable measures of outcomes across student subgroups, but prior research suggests score comparisons across gender groups may be complicated by the type of test items used. This paper presents…

Speeded tests set time limits so that few examinees can reach all items, and power tests allow most test-takers sufficient time to attempt all items. Educational achievement tests are sometimes described as "timed power tests" because the amount of time provided is intended to allow nearly all students to complete the test, yet this…

Prior research suggests that males outperform females, on average, on multiple-choice items compared to their relative performance on constructed-response items. This paper characterizes the extent to which gender achievement gaps on state accountability tests across the United States are associated with those tests' item formats. Using roughly 8…

Prior research demonstrates the existence of gender achievement gaps and the variation in the magnitude of these gaps across states. This paper characterizes the extent to which the variation of gender achievement gaps on standardized tests across the United States can be explained by differing state accountability test formats. A comprehensive…

Mixed-format tests containing both multiple-choice (MC) items and constructed-response (CR) items are now widely used in many testing programs. Mixed-format tests often are considered to be superior to tests containing only MC items although the use of multiple item formats leads to measurement challenges in the context of equating conducted under…

Many innovative item formats have been proposed over the past decade, but little empirical research has been conducted on their measurement properties. This study examines the reliability, efficiency, and construct validity of two innovative item formats--the figural response (FR) and constructed response (CR) formats used in a K-12 computerized…

The study examined the effects of item format, self-concept and anxiety on response changing behaviour. Four hundred undergraduate students who offered a counseling psychology course in a Nigerian university participated in the study. Students' answers in multiple--choice and true--false formats of an achievement test were observed for response…

Results in the engineering literature on "k out of n system reliability" can be used to characterize tests based on estimates of the probability of correctly determining whether the examinee knows the correct response. In particular, the minimum number of distractors required for multiple-choice tests can be empirically determined.…

To test further for efficacy of three-option achievement items, parallel three- and five-option item tests were distributed randomly to college students. Results showed no differences in mean item difficulty, mean discrimination or total test score, but a substantial reduction in time spent on three-option items. (Author/BS)

Do choice-type tests (multiple-choice, true-false, etc.) measure the same abilities or traits as free response (essay, recall, completion, etc.) tests? A large number of studies conducted with several different methodologies and spanning a long period of time have addressed this question. In this review, attention will be focused almost…

The proposition that the optimal number of options in a multiple choice test item is three was examined. The concept of functional distractor, a plausible wrong answer that is negatively discriminating when total test performance is the criterion, is discussed. Three distinct groups of achievers (high, middle, and low) on a national standardized…

The item difficulty and item discrimination of three multiple-choice item formats were compared in experimental and non-experimental settings. In the experimental study, 104 graduate students were randomly assigned to complete one of three forms of a multiple-choice test: (1) a complex alternative ("none of the above") as the correct answer; (2) a…

Commercial achievement tests often provide limited instructional guidance and seldom provide feedback specific to any given classroom. The most instructionally relevant achievement tests are those developed by an individual teacher for use with a particular class. This digest describes the steps of test construction and presents suggestions for…

A review of the development and innovation of testing at the higher education level focuses on Ralph Tyler's testing emphasis on the educational process and the objectives of instruction, a precursor to the current trend of integrating formative evaluation into the curriculum development process.
