The aim of this study was to identify students' motivational beliefs in science and revealed the connections between the profiles and three cognitive dimensions of science achievement through the examination of the socio-economic status (SES) and gender covariates of the profile memberships. Latent profile analysis using science motivational…

The aim of this study is to examine whether or not the positive and negative items in the Mathematical Self-Confidence Scale employed in TIMSS 2015 lead to wording effect. While examining whether the expression effect is present or not, analyzes were conducted both on the general sample and on a separate sample for female and male students. To…

The knowledge, skills and attitudes of prospective pre-school teacher towards science education enable more effective classroom practices and science teaching. Teaching scientific processes at an early age affects students' attitudes towards science in the coming years. In this context, this study was designed to examine the relationship between…

Big-Fish-Little-Pond-Effect (BFLPE) suggests that students form their own self-concept by comparing their abilities to those of their peers. This study aims to examine how students' gender, socioeconomic status, science achievement, and engagement dimensions (motivational and behavioral engagement) predict students' self-concept in science by…

In this paper, it is aimed to evaluate different aspects of students' response time to items in the mathematics test and their test effort as an indicator of test motivation with the help of some variables at the item and student levels. The data consists of 4th-grade Singapore and Turkish students participating in the TIMSS 2019. Response time…

Measurement invariance analyses are carried out in order to find evidence for the structural validity of the measurement tools used in the field of educational sciences and psychology. The purpose of this research is to examine the measurement invariance of Science Motivation and Self-Efficacy Model constructed by Instrumental Motivation to Learn…

Using IEA's Trends in International Mathematics and Science Study (TIMSS) 2019 data, this brief explores the relationship between students' gender, their confidence and achievement in mathematics and science, and their aspirations to pursue careers in these fields. We find that more boys than girls at grade 8 want to have a mathematics- or…

In this study, the effects of some student (e.g., gender, bullying, etc.) and school variables (e.g., emphasis on academic achievement, clarity of teaching, etc.) on the TIMSS 2015 science and mathematics achievement of eighth grade students in Türkiye were examined by controlling for the socioeconomic status of the students at the student and…

This survey design study was designed to test whether the graph skills and affective states of middle school students about graphs differ by their gender, grade level, and graph types (line, bar, and pie). The data collection instruments consisted of two scales developed by the authors and a Graph Skills Test, which consisted of graph questions…

In the current study, the appropriateness of the Mathematics Attitude Questionnaire administered to middle school 8th grade students in the TIMSS 2015 application to the exploratory structural equation and confirmatory factor analysis models was examined. The study was conducted on 6079 students making up the sample of Turkey. In the TIMSS 2015…

Women's underrepresentation in mathematics-related careers continues to concern policymakers, economists, and educators. This study addressed the issue by examining data from two international databases, namely IEA's "Trends in International Mathematics and Science Study 2015," and the World Economic Forum's "Global Gender Gap…

Science, technology, engineering, and mathematics (STEM) education is an international focus in teaching and learning, and factors influencing students' science achievement vary throughout the world. Guided by the Social Role and Expectancy-Value Theories, we investigated the role of fourth and eighth graders' gender and attitudes toward science…

School climate which is strongly related with the students' outcomes includes some of the components, among which disciplinary climate in schools was expressed as the dominant one. Safety and order in schools which is strongly related with the physical and emotional security stated as one of the indicator of disciplinary climate in schools. In…

In this research, the effect of using learning logs in the learning of length subjects of primary school fourth graders was investigated. The study group was composed of 35 state primary school students, determined by an easily accessible sampling method in the province of Tokat in 2014-2015 academic years. The method of the study is an…

Purpose: Studies in the literature have generally demonstrated that the causes of differential item functioning (DIF) are complex and not directly related to defined groups. The purpose of this study is to determine the DIF according to the mixture item response theory (MixIRT) model, based on the latent group approach, as well as the…
