"Mythbusters" uses multiple research methods to test interesting topics, offering research methods students an entertaining review of course material. To test the effectiveness of "Mythbusters" clips in a psychology research methods course, we systematically selected and showed 4 clips. Students answered questions about the clips, offered their…

This article proposes procedures for simultaneously assessing and controlling acquiescence and social desirability in questionnaire items. The procedures are based on a semi-restricted factor-analytic tridimensional model, and can be used with binary, graded-response, or more continuous items. We discuss procedures for fitting the model (item…

This article reports on a collaboration project between South Africa and Sweden, in which we want to investigate whether the emphasis in undergraduate mathematics courses for engineering students should be more conceptual than the current traditional way of teaching. On the basis of a review of the distinction between conceptual and procedural…

The development of phonological awareness (PA), the ability to reflect on the sound structure of words independent of their meaning, has been extensively explored in English-speaking children. However, this is not the case for other languages. The aim of this study was to develop a comprehensive PA test battery for German-speaking preschool…

A readily implemented procedure is discussed for interval estimation of indexes of interrelationship between items from multiple-component measuring instruments as well as between items and total composite scores. The method is applicable with categorical (ordinal) observed variables, and can be widely used in the process of scale construction,…

This article introduces the Measurement Skills Assessment (MeSA), which was designed to evaluate the mastery of measurement in elementary school students. The primary objectives for the MeSA include covering a broad range of measurement concepts, distinguishing between major subtypes of measurement, and constructing a continuum of items varying in…

As Rupp and Templin (2008) stated directly, diagnostic classification methods "are confirmatory in nature." Methods, though, are neither inherently confirmatory nor exploratory. Diagnostic classification modeling, with its analytical and computational obstacles eventually yielding as a comprehensive and potent discipline emerges, will…

Handheld calculators have been used on the job for more than 30 years, yet the degree to which these devices can affect performance on employment tests of mathematical ability has not been thoroughly examined. This study used a within-subjects research design (N = 167) to investigate the effects of calculator use on test score reliability, test…

We used collaborative testing in a veterinary physiology course (65 students) to answer the following questions: 1) do students with individual correct responses or students with individual incorrect responses change their answers during group testing? and 2) do high-performing students make the decisions, that is, are low-performing students…

This article investigates several questions regarding the impact of different item formats on measurement characteristics. Constructed response (CR) items and multiple choice (MC) items obviously differ in their formats and in the resources needed to score them. As such, they have been the subject of considerable discussion regarding the impact of…

There is much debate on the merits and pitfalls of standardized tests for college admission, with questions regarding the format (multiple-choice versus constructed response), cognitive complexity, and content of these assessments (achievement versus aptitude) at the forefront of the discussion. This study addressed these questions by…

Previously, a small scale, interview-based, 3-year longitudinal study (ages 11-14) in one school had suggested a learning progression related to the concept of a substance. This article presents the results of a large-scale, cross-sectional study which used Rasch modeling to test the hypothesis of the learning progression. Data were collected from…

Due to the wide application of advanced technology in education, many attitude scales have been developed to evaluate learners' attitudes toward educational tools. However, with the rapid development of emerging technologies, using blogs as one of the Web 2.0 tools is still in its infancy and few blog attitude scales have been developed yet.…

A taxonomy of learning objectives generally refers to a schema to classify the levels of learning. In 1956, Benjamin Bloom, with a group of educational psychologists, created a taxonomy for classifying educational objectives using six major categories of thinking skills: (a) knowledge (recalling information), (b) comprehension, (understanding the…

Developed for the Armed Services Vocational Aptitude Battery (ASVAB) Career Exploration Program, the Find Your Interests (FYI) inventory was designed to help students learn about their career-related interests. The FYI is a 90-item interest inventory based on Holland's (1973, 1985, 1997) widely accepted theory and taxonomy of career choice. The…
