Background: Concerning students' difficulties with fractions, many explanatory approaches are based on the distinction between conceptual knowledge and procedural knowledge. For further research in this field, it is thus crucial to make these constructs accessible to valid measurement. Aims: In this study, we aim at developing a test instrument…

In the process of educating physically literate individuals, physical educators are tasked with assessing health-related fitness of their students. It is essential to identify or develop appropriate field tests of muscular power for use in physical education settings. This study assessed jumping power in a sample of fourth, sixth, and eighth…

While school self-concept is an important facilitator of a student's school engagement, previous studies rarely investigated whether it may also explain the change in students' school engagement during secondary school. Moreover, as social relations play an increasingly important role in adolescence, the current research distinguishes between the…

Research on learning through serious games has been gaining importance in recent years. We develop the serious game "Tempoly," concerning the learning of the four arithmetic operations on polynomials. A quasi-experimental study was carried out with 95 students of 8th grade, to evaluate the reactions of the students to the game, the…

The New York State Education Department (NYSED) has a partnership with Questar Assessment Inc. (Questar) for the development of the 2020 Grades 3-8 Mathematics 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 Grades 6-8…

Objective: The objective of this study was to compare caffeine consumption in the morning, afternoon, and evening in adolescents with and without ADHD and examine associations with sleep functioning. Methods: Participants were 302 adolescents (ages 12-14) with (n=140) and without (n=162) ADHD. Adolescents wore actigraph watches to assess total…

The study tested the hypothesis that there are sex differences in the pathways to mathematical development. Three-hundred and 42 adolescents (169 boys) were assessed in various mathematics areas from arithmetic fluency to algebra across 6th to 9th grade, inclusive, and completed a battery of working memory, spatial, and intelligence measures in…

Understanding the structure, antecedents, and outcomes of students' emotions has become a topic of major interest in research on mathematics education. Much of this work is based on the Achievement Emotions Questionnaire--Mathematics (AEQ-M), a self-report instrument assessing students' mathematics-related emotions. The AEQ-M measures seven…

Introduction: This study evaluated performance and engagement on the tactile science alternate assessment based on alternate academic standards (AA-AAS). This assessment was designed for students with significant intellectual disabilities and visual impairments (i.e., blindness and low vision). Four primary research questions guided this study.…

This research is a causal study that examines the moderator role of parental exam anxiety in the relationship between eighth-grade students' exam anxiety and high school entrance exam success. Participants of the study consisted of a total of 353 eighth-grade students attending seven different middle schools in the North region of Türkiye.…

Background: Gamification is the use of game design elements, such as rules of play, point scoring and competition, in a non-game context, in learning activities. We designed a game, based on the famous augmented reality game "Pokémon GO," called Insects GO in which players should capture images of real insects with their mobile phones.…

Adolescents with positive attitudes towards the legal authorities are unlikely to adopt delinquent behaviours. To examine the role school can play in shaping such attitudes, we questioned 465 middle school students to assess how their emotional relationships with teachers (teachers' compassionate love, teachers' esteem) relate to their attitudes…

The authors examined middle level teachers' perceptions and experiences of leadership support during the sudden transition to emergency remote teaching (ERT) during the COVID-19 pandemic. For this qualitative case study, the research questions were: How did middle school teachers perceive their leaders' support for teaching online? What were…

For some students, the transition from primary to secondary school is a difficult and stressful event that can have potential negative effects on their psychological wellbeing, social adaptability, and academic achievement. Although several individual, environmental, and family protective factors have been investigated, direct and indirect…

This study evaluated the construct validity of six scoring traits of an automated writing evaluation (AWE) system called "MI Write." Persuasive essays (N = 100) written by students in grades 7 and 8 were randomized at the sentence-level using a script written with Python's NLTK module. Each persuasive essay was randomized 30 times (n =…
