Schools often have to decide between extending the length of the school year or the school day. This paper examines the effects of changes in the distribution of instructional time on eighth-grade student achievement through a methodological framework that disaggregates total yearly instructional time into separate inputs for days per year and…

Background: Spatial skills and mathematical ability have been repeatedly identified as critical for achievement in Science, Technology, Engineering, and Mathematics (STEM). Previous studies have identified correlations between spatial skills and mathematical achievement; however, questions remain regarding improvements in non-spatial areas…

The New York State Education Department (NYSED) has a partnership with Questar Assessment Inc. (Questar) for the development of the 2020 Grades 3-8 English Language Arts Tests. Teachers from across the State work with NYSED in a variety of activities to ensure the validity and reliability of the New York State Testing Program (NYSTP). The 2020…

Smartphone addiction among adolescents has become a major concern. The present study aims to investigate the psychometric properties of the Persian Smartphone Addiction Scale - Short Version (SAS-SV). A sample of 398 adolescents (52% girls and 48% boys) completed the SAS-SV, the Kutcher Adolescent Depression Scale (KADS), and the Young Internet…

The Concept Formation subtest of the Woodcock Johnson Tests of Cognitive Abilities represents a dynamic test due to continual provision of feedback from examiner to examinee. Yet, the original scoring protocol for the test largely ignores this dynamic structure. The current analysis applies a dynamic adaptation of an explanatory item response…

Undergraduate students majoring in mathematics often face difficulties in comprehending mathematical proofs. Inspired by a number of studies related to students' proof comprehension, and Mejia-Ramos et al.'s study in particular, a test was designed in relation to the proof comprehension of the Cauchy Generalized Mean Value Theorem (CGMVT). The…

Objective: To evaluate the measurement structure of the "Job Satisfaction of Persons with Disabilities Scale" (JSPDS) in a sample of employed U.S. Americans with disabilities. Design: A quantitative descriptive design using exploratory factor analysis (EFA) and correlational analysis. Participants: Two hundred and fifty-nine individuals…

Achievement tests are used to make high-stakes (e.g., special education placement) decisions, and previous research on norm-referenced assessment suggests that errors are ubiquitous. In our study of 42 teacher trainees, utilizing five of the six core subtests of the Kaufman Test of Educational Achievement, Third Edition (KTEA-3), we found that…

This study examined the validity of a 14-item two-factor person-environment fit scale for creativity (PEFSC) to measure the personal and environmental components of creativity. A sample of 2,475 participants completed the PEFSC for evaluating the factor structure. For convergent, discriminant, and incremental validities, a subsample (N = 362)…

Assessment of learning within the online classroom is a growing point of discussion, particularly with regard to student exam performance. In 2017, an online Organizational Behavior course offered by a large, Christian university was revised to include a change in the quizzes offered to students to prepare for each of four exams. This study…

Learning outcomes are the first and most essential element of the curricula and the correct and rigorous determination of the learning outcomes is very important in order to ensure formal education in schools to be well-planned and to design and apply curriculums effectively. Because, the other elements of the curriculum which are content,…

Multiple choice questions (MCQs) are commonly used for assessing students, but medical teachers may lack training in writing them. MCQs often have imperfections called item-writing flaws (IWFs) that can affect students' results and impede objective evaluation of their knowledge. This study aimed to evaluate a guideline-based faculty development…

Background/Context: When new, rigorous standards are adopted, teachers often need to learn new content and new ways of teaching while concurrently attending to accountability demands. Both formal and informal school structures potentially enable this new learning, and school leaders likely influence the nature of these structures.…

Selective cutoff reporting in primary diagnostic accuracy studies with continuous or ordinal data may result in biased estimates when meta-analyzing studies. Collecting individual participant data (IPD) and estimating accuracy across all relevant cutoffs for all studies can overcome such bias but is labour intensive. We meta-analyzed the…

This article presents the adaptation of the MacArthur Communicative Development Inventory (CDI; Fenson et al., 1993, "Guide and technical manual for the MacArthur Communicative Development Inventories." San Diego, CA: Singular Press; Fenson et al. 1994, Variability in early communicative development. "Monographs of the Society for…
