Background/purpose: This study aims to examine the validity and reliability of factors influencing students' decisions in selecting the elementary education study program and to identify the most dominant factor. Materials/methods: This quantitative study employed a cross-sectional design involving 722 students from various universities across…

The SPARK cohort was established to facilitate recruitment in studies of large numbers of participants with autism spectrum disorder (ASD). Online registration requires participants to have received a lifetime professional diagnosis by health or school providers although diagnoses are not independently verified. This study was set to examine the…

Evaluators are often called upon to assess the effects of programs. To assess a program effect, evaluators need a clear understanding of how a program effect is defined. Arguably, the most widely used definition of a program effect is the counterfactual one. According to the counterfactual definition, a program effect is the difference between…

This study aimed to determine the validity of the ActiGraph wGT3X-BT for step counts (SC) at five different body locations in laboratory settings. A total of 29 male adults participated in this study. The participants walked or ran for different speeds on the treadmill while wearing ActiGraph wGT3X-BT on their right wrist (RW), left wrist (LW),…

Systematic reviews and meta-analyses are essential for drawing conclusions regarding etiologic associations between exposures or interventions and health outcomes. Observational studies comprise a substantive source of the evidence base. One major threat to their validity is residual confounding, which may occur when component studies adjust for…

Many mathematics departments have transition to proof (TTP) courses, which prepare undergraduate students for proof-oriented mathematics. Here we discuss how common TTP textbooks connect three topics ubiquitous to such courses: logic, proof techniques, and sets. In particular, we were motivated by recent research showing that focusing on sets is…

Sensory issues are highly prevalent in autism and previous findings support a relationship between questionnaires of sensitivity and autistic symptoms and traits, whereas studies that examine this relationship through behavioural assessments of sensitivity are less consistent. The current study explores these differences and suggests that…

A negative association between symptoms of teacher burnout (e.g., emotional exhaustion) and students' academic outcomes has been demonstrated in previous research. Although, in theoretical models, it has been suggested that this association can be explained through changes in teachers' instructional behavior, these mediating processes have not yet…

Objective: Currently, no clinically feasible objective measures exist that are specific to the signs of adductor laryngeal dystonia (LD), deterring effective diagnosis and treatment. This project sought to establish concurrent validity of a new automated acoustic outcome measure, designed to be specific to adductor laryngeal dystonia (AdLD): the…

Understanding the response process used by test takers when responding to multiple-choice questions (MCQs) is particularly important in evaluating the validity of score interpretations. Previous authors have recommended eye-tracking technology as a useful approach for collecting data on the processes test taker's use to respond to test questions.…

In the article, we prove 18 inequalities involving inradius, a length of one side and one additional element of a given triangle. 14 of these inequalities are the necessary and sufficient conditions for the existence and uniqueness of such a triangle. All proofs are based on standard methods of calculus and can serve as a good demonstration of the…

One of the challenges of discussing validity arguments for machine scoring of essays centers on the absence of a commonly held definition and theory of good writing. At best, the algorithms attempt to measure select attributes of writing and calibrate them against human ratings with the goal of accurate prediction of scores for new essays.…

School psychologists often have reason to suspect that students may not be putting forth full effort during diagnostic tests, or that questionnaire or rating scale data are not credible. However, such suspicions must be tested carefully to yield data-based conclusions. Structured, empirically supported methods for assessing the "response…

This study sought to develop and validate an instrument to test the self-efficacy of teaching engineering design. This study is part of a larger effort to develop an instrument for both pre-service and in-service teachers of Science, Technology, and Engineering education. The focus of this study is on the initial instrument creation process and…

This article documents the results of a meta-analysis of available correlational validity evidence for the Social Skills Improvement System Performance Screening Guide (SSIS-PSG), which is a brief teacher-completed rating scale designed to be used as part of universal screening procedures. Article inclusion criteria included (a) published in…
