This article presents a simple, cognitive theory of science and learning. The first section of the paper develops the theory's two main propositions: (i) A wide range of scientific activities rely heavily on one type of reasoning, hypothetical thinking, and (ii) This type of reasoning is also useful to students for learning science content. The…

Doctoral qualifying exams are considered essential in assessing a student's readiness for research and advanced studies. Despite their significant role in many physics programs, questions have been raised about their format, execution, and relevance. Our research investigates perceptions held by faculty members regarding the graduate doctoral…

This study is the first statewide analysis of the effectiveness of the Texas Teacher Incentive Allotment (TIA) program. Introduced in 2019, TIA is the most significant and unprecedented teacher merit-pay system in the U.S. Leveraging the Synthetic Control Method (SCM), we construct a counterfactual scenario to assess the causal impact of TIA on…

Across the United States, suspension bans have become a popular policy response to address excessive and inequitable use of suspension in schools. However, there is little research that examines what strategies school staff employ when suspension is no longer permitted. I examine the effect of New York City's suspension ban on the use of a…

Students' experience errors in solving proportional problems and prospective teachers' experience were the same thing. Research that explained the wrong strategy for understanding proportional problems still needed to be completed. Objectives to describe the wrong strategies chosen by prospective teachers in solving proportional questions and the…

Considering the undeniable importance of examining the role of domain- and skill-specific individual difference factors in second-language (L2) writing research, this study examined the possible roles of English-as-a-foreign-language (EFL) learners' ideal L2 writing self and growth L2 writing mindset in their L2 writing grit, which may in turn…

This study addresses the underexplored terrain of conceptualizing and operationalizing race and ethnicity as grouping variables in Differential Item Functioning (DIF) studies within the context of psychometric research. The investigation extends beyond the identification of DIF and delves into the theoretical framing and communication of findings…

Middle school is one of the most important times during which students gain knowledge. However, a large proportion of adolescents have continued to complete middle school without mastering essential knowledge of, and skills in, vocabulary and reading comprehension. Adolescents who miss school in the 30-60 days leading up to high-stakes exams…

We collected data on students' self-assessment behavior from four sections of a Calculus II course. Students were asked to write their expected scores on each of the weekly in-class quizzes and problems in the exams, immediately after they completed them. They were then asked to justify their expectation in writing. One-on-one interviews were…

Objective: The aim of the present study was to test the factorial invariance and convergent validity evidence of scores on the Somatic Symptom Scale (SSS)-8 with a national sample of adults living in the United States. Method: A data collection contracting service was hired to recruit a national, non-clinical sample (N = 821) of adults in the…

The proposed paper utilizes teacher and student data from the 2014 U.S. National Assessment for Education Progress 8th grade Civics test (NAEP-Civics8) to explore the relationship between teacher pedagogical practices and other factors (i.e., teacher credentials, teacher professional characteristics, individual traits, and teachers' education…

As long-term effects of educational programs cannot be sufficiently addressed by evaluators during short duration implementation grants, researchers become responsible for investigating sustainability of effects and addressing concerns of policy makers and grant funding agencies. This study examines the impact of the TAP System for Teacher and…

No research has been conducted on PTSD manifestation in children with severe or moderate intellectual disability (SID; IQ 20-49) and no PTSD measurement instrument was available. This pilot explores the psychometric properties of a new diagnostic instrument to investigate trauma and to classify PTSD in children with SID. The Diagnostic Interview…

The growing use of analytics has increased the demand for more highly data literate graduates. Awareness of ambiguity in data has been suggested as a new data literacy skill. Here, we describe a student-centered semester-long project that can be used to teach this skill in an introductory analytics or database course. The project requires students…

While test anxiety is a problem in asynchronous online courses, few studies have systematically investigated learning factors influencing test anxiety in asynchronous online courses. Additionally, emotional engagement has been identified as a mediator between learning factors and test anxiety. Therefore, this study clarified the mediating role of…
