This paper describes a study that focused on developing, validating and standardizing a dyscalculia test, henceforth called the Dyscalculia Test. Out of the 4,758,800 students in Nigeria's upper primary and junior secondary schools, I randomly drew a sample of 2340 students, using a multistage sampling procedure that applied various sampling…

Teachers' digital competence (DC) is an important condition for the effective application of technology in education. Although several DC tools have been designed, adjustments to digital education and pedagogical or professional components are still scarce. Therefore, this study aims at developing a new instrument for assessing teachers' DC…

Multiple-choice questions (MCQs) are commonly used in undergraduate introductory science, technology, engineering, and mathematics (STEM) courses, and substantial evidence supports the use of student-created questions to promote learning. However, research on student-created MCQ exams as an assessment method is more limited, and no studies have…

In Japan, school teachers experience mental health issues, leading to absences or leave from their duties. While extended working hours significantly contribute to this problem, diminished self-esteem has emerged as the primary causal factor. Reduced self-esteem is frequently correlated with diminished self-efficacy across multiple facets of…

Students who hold minoritized identities are underrepresented in science, technology, engineering, and math (STEM) fields. Educational institutions often apply a deficit lens to understanding disproportionate outcomes between minoritized students and those from the cultural majority. Community Cultural Wealth (CCW) is an asset-based framework that…

We are developing the Equitable Screening to Support Youth (ESSY) Whole Child Screener to address concerns prevalent in existing school-based screenings that impede goals to advance educational equity using universal screeners. Traditional assessment development does not include end users in the early development phases, instead relying on a…

This study sought to develop an Academic School Climate Scale measuring students' perceptions of the learning environments at their schools. With a pilot sample of 1,265 students and validation sample of 14,773 students in Grades 4-12 in schools across the U.S., results of EFA and CFA supported a bifactor model with a general factor and three…

Analyzing heterogeneous treatment effects (HTE) plays a crucial role in understanding the impacts of educational interventions. A standard practice for HTE analysis is to examine interactions between treatment status and pre-intervention participant characteristics, such as pretest scores, to identify how different groups respond to treatment.…

The "Morbidity and Mortality Weekly Report" ("MMWR") series of publications is published by the Office of Science, Centers for Disease Control and Prevention (CDC), U.S. Department of Health and Human Services. Articles included in this supplement are: (1) Overview and Methods for the Youth Risk Behavior Surveillance System --…

The washback effects of high-stakes tests have become conspicuous and prevalent in Thai educational contexts. Yet, researchers in language assessment still have much to strive towards to understand the nuanced role of teacher factors as a mediator between the washback effects of high-stakes tests and teaching. This study aimed to investigate how…

This study aims to develop a valid and reliable scale for determining the self-efficacy of teachers toward context-based science education. This study employed a survey design. The sample has formed 433 science teachers working in Kayseri province in the 2020-2021 spring semester. Firstly, an item pool of 85 items was developed by reviewing the…

Hundreds of articles have explored the extent to which individuals accept evolution, and the Measure of Acceptance of the Theory of Evolution (MATE) is the most often used survey. However, research indicates the MATE has limitations, and it has not been updated since its creation more than 20 years ago. In this study, we revised the MATE using…

Developing new scales to measure aspects of mentoring, including guidance in scientific communication (SciComm), is important to enhance success among trainees pursuing research careers in science and medicine. This study examined the psychometric properties of three new measures, based on social cognitive career theory (SCCT), as mentors address…

Background: In many countries and regions, such as the United States, Europe and China, a trend has emerged in which students' enthusiasm for STEM is declining. This decline may be related to students' lack of science self-efficacy. An accurate examination of students' science self-efficacy can provide a research foundation for how to cultivate…

In this paper, we described the development of the High School Wave Optics Test (HSWOT). Firstly, 56 conceptual, multiple-choice items with a single correct answer and three distractors were created. Next, we conducted an initial review of the items which resulted in reducing the item pool to 44 highest quality items. Validity evidence and…
