Factor loadings and item discrimination parameters play a key role in scale construction. A multitude of heuristics regarding their interpretation are hardwired into practice--for example, neglecting low loadings and assigning items to exactly one scale. We challenge the common sense interpretation of these parameters by providing counterexamples…

The aim of this research is to develop a reliable and valid scale to determine the mathematical thinking skills of gifted students. In addition, with the developed scale, thinking skills of gifted students was examined in terms of various variables. In this context, the research was carried out on two different study groups. The first stage of…

Purpose: The answer-copying tendency has the potential to detect suspicious answer patterns for prior distributions of statistical detection techniques. The aim of this study is to develop a valid and reliable measurement tool as a scale in order to observe the tendency of university students' copying of answers. Also, it is aimed to provide…

Statement of Problem: Although there is a rapidly increasing interest in creativity in specific domains such as science and math, there are not enough valid and reliable scales to assess students' creativity in these domains. If mathematical creativity potential can be measured, then the curriculum can be adapted to address the needs of creative…

Organizational stressors can potentially elicit a number of undesirable consequences for sport performers. It is, therefore, imperative that psychologists better understand the demands that athletes encounter via their exploration and assessment. However, although researchers have identified a wide range of organizational stressors in competitive…

Administration of the Test of Spoken English (TSE) yields tapes of oral performance on items within six sections of the test. Trained scorers subsequently rate responses using four proficiency scales: pronunciation, grammar, fluency, and overall comprehensibility. This project examined the consistency of statistical relations among TSE scores with…

This study examined the relationship of a machine-scorable, constrained free-response computer science item that required the student to debug a faulty program to two other types of items: multiple-choice and free-response requiring production of a computer program. The free-response items were from the College Board's Advanced Placement Computer…

To explore theoretical issues inspired by the Likert response format, 2 social insight scales were developed and administered to 391 Air Force recruits. Results demonstrate the applicability of the probabilistic response format to measure differences in nontraditional knowledge domains and the existence of a factor that may be interpreted as…

The Administrator Professional Leadership Scale (APLS) was developed to measure the professional leadership quality of a school principal, and to provide principals with anonymous feedback on teachers' perceptions of their leadership. Further refinement was carried out to increase its reliability; to discover categories of administrator behavior…

This study examined the relationship of multiple-choice and free-response items contained on the College Board's Advanced Placement Computer Science (APCS) examination. Subjects were two samples of 1,000 randomly drawn from the population of 7,372 high school students taking the 1988 examination of the APCS "AB" form. Most were high…
