A number of validated survey instruments for assessing technological pedagogical content knowledge (TPACK) do not accurately discriminate between the seven elements of the TPACK framework particularly technological content knowledge (TCK) and technological pedagogical knowledge (TPK). By posing simple questions that assess technological,…

Objective: To translate and evaluate the psychometric properties of an Arabic-language version of the Depression Anxiety Stress Scales (DASS). Method: The items were translated, back translated, refined, and tested in an Australian immigrant sample (N = 220). Results: Confirmatory factor analysis showed that the Arabic DASS discriminates between…

The purpose of the research is to examine the effect of different response formats on student performance on introductory accounting exam questions. The study analyzes 1104 accounting students' responses to quantitative questions presented in two formats: multiple-choice and fill-in. Findings indicate that response format impacts student…

The aim of this study was to develop a scale to determine the barriers affecting psychological help-seeking in college students. In line with this purpose, the validity and reliability of the scale were examined in five different studies. Exploratory factor analysis results suggested that the scale consists of five dimensions, labeled as…

Objective: This article reports a study that developed and validated the Perceived Social Work Competence Scale (PSWCS) for assessing social work students' competence in Mainland China. Method: The indicators were generated by a broad empirical review of recent literature, confirmed by experts, and indigenized by means of two focus groups of…

This study defines subpopulation item parameter drift (SIPD) as a change in item parameters over time that is dependent on subpopulations of examinees, and hypothesizes that the presence of SIPD in anchor items is associated with bias and/or lack of invariance in three psychometric outcomes. Results show that SIPD in anchor items is associated…

Sex differences in typical development can provide context for understanding ASD. Baron-Cohen ("Trends Cogn Sci" 6(6):248-254, 2002) suggested ASD could be considered an extreme expression of normal male, compared to female, phenotypic profiles. In this paper, sex-specific M-CHAT scores from N = 53,728 18-month-old toddlers, including n…

School self-evaluation (SSE), as an important leverage for quality assurance, often relies on surveys among staff members to collect information on the schools' functioning. The extent to which respondents cognitively process items as developers intended them determines the cognitive validity of SSE results. However, it is unclear what problems…

This study investigates the psychological effect of a wrong question with wrong items on answering to the next question in a test of structure. Forty students selected through stratified random sampling are given 15 questions of a standardized test namely a TOEFL structure test in which questions number 7 and number 11 are wrong and their answers…

Educational systems typically contain a large pool of items (questions, problems). Using data mining techniques we can group these items into knowledge components, detect duplicated items and outliers, and identify missing items. To these ends, it is useful to analyze item similarities, which can be used as input to clustering or visualization…

The concept of variability is central to statistics. In this research report, we review mathematics education research on variability and, based on that review and on feedback from an expert panel, propose a learning progression (LP) for variability. The structure of the proposed LP consists of 5 levels of sophistication in understanding…

Main idea and summary are essential elements of reading comprehension. We report results from Grades 4 and 5 student performance on two years of state-mandated standardized reading testing which indicate that students perform statistically significantly lower on main idea and summary questions on the tests than any other question category. In this…
