The advantages and disadvantages of ability grouping for student achievement are strongly contested, with studies presenting different results. However, much of this research has focused on class-level or subject-level ability grouping. Relatively less research has focused on school-level ability grouping. More importantly, the role of teacher…

The relation between cognition and life satisfaction is shaped by several factors. The present research investigated whether mindreading skills are linked to subjective well-being and anxiety during the transition into adolescence. Specifically, our aim was to investigate individual differences in those constructs and gendered relational patterns.…

This study aims to compare the G and Phi coefficients as estimated by D studies for a measurement tool with the G and Phi coefficients obtained from real cases in which items of differing difficulty levels were added and also to determine the conditions under which the D studies estimated reliability coefficients closer to reality. The study group…

Background: The development of learning attitudes during middle school transition and adaptation is critical, as shown by Self-Determination Theory (SDT). However, the development of adolescents' learning attitudes throughout middle school and the impact of parenting styles on this development remains largely unexplored. Objective: This research…

This study is a case study within a three-year-long design research study. The purposes of this study are twofold. The first purpose includes investigating whether there is a significant difference in seventh-grade students' proportional reasoning skills before and after a teaching experiment conducted in line with the perspectives of Hypothetical…

The authors of the scientific study examine the impact of the relationship of theoretical knowledge on practical skills in technical subjects at the lower secondary level of education in the Slovak Republic. After determining the research problem and hypotheses, they bring the processed results in the form of tables and figures. Quantitative…

The aim of this paper is to analyze a set of didactic materials developed to teach English as an Additional Language at a Brazilian public school in Rio de Janeiro. Such materials were designed to invite 7th grade students with diverse social, racial, and economic backgrounds to learn about the world and the English language from viewpoints that…

Based on control-value theory (CVT), we examined longitudinal relations between students' control and value appraisals, three activity-related achievement emotions (enjoyment, anger, and boredom), and math achievement (N = 1,716 fifth and seventh grade students). We assessed appraisals and emotions with self-report measures of perceived competence…

This article presents an analysis of students' conceptual understanding of technology. The study focused on two groups of seventh-grade students located in Bogotá, Colombia, living in rural and urban areas and participating in activities developed in a virtual learning network. The methods used in this study followed grounded theory (Strauss &…

The main aim of this research is to examine the effect of an instructional design based on the Algo-Heuristic Theory of Instruction (AHTI) on students' mathematics performance and logical thinking skills in the subject of 7th grade mathematics. The research is grounded in a mixed method. In the quantitative part of the research, a…

One of the primary goals of teacher education is to aid preservice candidates in formulating a personal philosophy of teaching that is research-based. Teacher candidates should recognize that their philosophy of teaching and learning must be grounded in research-affirmed theory, certain dimensions of which (e.g., motivation) are critical to…

In this article, we present the first results of the project OPEN-MATH. The research project aims at acknowledging the need for learning environments with differentiation strategies for all. We developed a model for inclusive mathematics learning, based on the Theory of Objectification and a broad idea of differentiation realized through Open…

This study evaluates the psychometric properties of three different forms of the Writing Apprehension Test (WAT; Daly & Miller, 1975) through Rasch analysis. For this purpose, the fit statistics and correlation coefficients, and the reliability, separation ratio, and chi-square values for the facets of item and person calculated for the…

The study aims to examine whether differential item function is displayed in three different test forms that have item orders of random and sequential versions (easy-to-hard and hard-to-easy), based on Classical Test Theory (CTT) and Item Response Theory (IRT) methods and bearing item difficulty levels in mind. In the correlational research, the…

This study investigated longitudinal associations between mathematics- and literacy-related causal attributions and self-concepts of ability among Finnish adolescents (N = 237). Questionnaires were administered to adolescents in Grades 7 and 9 to obtain information on their causal attributions and self-concepts of ability. The results showed that…
