Purpose: This study aimed to determine the expectations of students from mathematics teachers in the planning phase of lesson study (LS) in mathematics classrooms. Design/methodology/approach: This study reported only a part of large-scale action research. The participants were Grade 8 students selected by the convenience sampling method. The data…

One of the main objectives of international large-scale assessments is to make comparisons between different countries, education policies, education systems, or subgroups. One of the main criteria for making comparisons between different groups is to ensure measurement invariance. The purpose of this study was to test the measurement invariance…

Writing is the result of our desire to express our feelings, thoughts, dreams, and ourselves. In today's education, with the penetration of technology into our lives, what we express not only on paper but also on the screen is within the scope of writing skills. Writing is a language skill that requires high-level mental skills such as producing a…

This study aims to first investigate the effect of the extreme response style (ERS) which could lead to an attitude-achievement paradox among the countries participating in the Trends in International Mathematics and Science Study (TIMSS 2015), and then to determine the individual- and country-level relationships between attitude and achievement…

Purpose: Cross-cultural comparisons based on ordinal Likert-type rating scales have been threatened by response style which is systematic tendencies to respond to items regardless of the item content. So, this study aimed to investigate the effect of extreme response style and acquisance response style on TIMSS 2015 data. Method: The sample of…

Trends in International Mathematics and Science Study (TIMSS) data reveal that setting high standards for the overall mathematics curriculum and ensuring teachers adhere to these standards may not necessarily lead to better learning outcomes for students. There are significant gaps between the intended and implemented grade 8 mathematics curricula…

In the literature, response style is one of the factors causing an achievement-attitude paradox and threatens the validity of the results obtained from studies. In this regard, the aim of this study is two-fold. Firstly, it attempts to determine which item response tree (IRTree) models based on the generalized linear mixed model (GLMM) approach…

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…

Academically resilient students are those students who are academically successful, despite coming from the socioeconomically disadvantaged backgrounds that have typically predicted poorer educational outcomes. These students are an important group to study because if policymakers can understand what factors may have contributed to their…

Background: The present study investigates what factors related to the school context influence student achievement on TIMSS mathematics tests across countries. A systematic review of the literature on PIRLS, TIMSS, and ICCS was conducted upstream to identify those school, teacher, and classroom factors shown to be useful predictors of student…

Teacher motivation is one of the factors that affect the realization of the teaching objectives, motivation and academic achievement of student. This study aimed to answer to the question "How is the relation between the students' academic (sciences and mathematics) achievement and teachers' morale/motivation in Singapore, Japan, Finland and…

The "Comparative Indicators of Education" report series has been published on a biennial basis since it began in 2002, although this year's is the first to expand its focus to the G-20 countries, having previously been focused on the G-8 countries. "Comparative Indicators of Education in the United States and Other G-20 Countries:…

This study used a diagnostic testing approach to compare the mathematics achievement of eighth-grade students across a sample of 20 countries, analyzing data from the Third International Math and Science Study-Revised (TIMSS-R, 1999). Using the rule-space method, student mastery was measured on 23 specific content knowledge and processing…
