In this study, an attempt was made to develop a valid and reliable measurement tool to determine teachers' self-efficacy levels for teaching metacognitive listening strategies. The study group consisted of 205 teachers for EFA and 248 teachers for CFA. As a result of the analyzes, a scale consisting of 16 items with 4 factors was developed. It was…

In this paper, a simple proof of the Morley's Trisector Theorem is presented which involves basic plane geometry only. The use of backward geometric approach, trigonometry or advanced mathematical techniques is not required. It is suitable for introducing to secondary or undergraduate students, as well as teachers or instructors for learning or…

The "k"-means clustering method, while widely embraced in college student typology research, is often misunderstood and misapplied. Many researchers regard "k"-means as a near-universal solution for uncovering homogeneous student groups, believing its success hinges primarily on the selection of an appropriate "k."…

In response to a call for research on using the SATs and ACTs for U.S.-based college and university admissions, researchers systematically interrogated the literature surrounding both tests, using a framework for validity evidence built upon the "Standards of Educational and Psychological Testing" and Kane's contemporary view of…

Fuzzy regression-discontinuity evaluations of college remediation often find negative and null estimates of local average treatments effects (LATEs), but with substantial heterogeneity. We find that a remedial quantitative skills course at Wellesley College has a modestly positive LATE on participation in mathematically intensive fields of…

Teaching mathematical modeling is a demanding task. Thus, fostering teachers' competencies in this regard is an essential component of teacher education. Recent conceptualizations of teachers' competencies include situation-specific skills based on the concept of noticing, which is of particular interest for the spontaneous reactions needed when…

This study aims to (1) produce an instrument for measuring college student entrepreneurial skills; (2) describe the quality of the measurement instrument for college students' entrepreneurial skills; (3) describe the practicality of the measurement instrument for college students' entrepreneurial skills. The method used in this study is the…

The Motivated Strategies for Learning Questionnaire (MSLQ) is one of the most widely used instruments to measure students' motivation and self-regulated learning. However, the MSLQ was developed and has been predominantly used in the Western context, is a domain-general measure, and is quite lengthy. Hence, adapting the MSLQ to the Chinese…

This study aimed to develop a two-tier light concept test to identify student concept understanding of light. The development of the test was carried out through the content validity, construct validity, and reliability test stages using the Item Response Theory (IRT). The sample consisted of 81 students during the second semester at five…

The aim of this study was to develop and validate a psychometrically-sound instrument to assess students' perceptions about class cohesion. Two studies were conducted. In Study 1, four steps were established: (1) development of the Class Cohesion Questionnaire (CCQ); (2) item selection; (3) item compression; and (4) exploration of psychometric…

There is a clear need for highly competent health sciences experts. No instrument currently exists for assessing the generic competences of health sciences students. The aim of this study is to develop and psychometrically test the Health sciences Generic Competence (HealthGenericCom) instrument. The instrument development four step process has…

Introduction: The objective was to evaluate the factor structure and propose a new version of the Rosenberg Self-Esteem Scale with only positive items to overcome the method effect associated with negative items. Method: A version A (positive and negative items) and a version B (only positive items) were considered. A sample of 350 university…

This study aims to validate a Korean version of the Brief Version of the Child Abuse Potential Inventory (BCAP-K) for use with childcare providers in South Korea. By employing a stratified sampling method, 808 childcare providers in charge of infants' classes were selected for participation. Participants completed a questionnaire that included…

The Content Proximity Project was designed to improve the content validity of the MAP® Growth™ assessments while retaining the ability for the test to adapt off-grade and meet students wherever they are in their learning. Two main features of the project were the development of an enhanced item selection algorithm, and a spring pilot study…

The Cognitive Test Anxiety Scale (CTAS) is a unidimensional scale designed to measure the cognitive aspect of test anxiety. The instrument has been adapted in several countries, and convincing psychometric properties have been found; however, uncertainties remain regarding its factor structure. Therefore, the aim of this study is twofold: to…
