This study aims to identify foreign-origin words found in reading texts in secondary school Turkish textbooks. The study was conducted in a qualitative research design and the research object is Turkish textbooks prepared by the Ministry of National Education Publications for the 5th, 6th, 7th, and 8th grades of secondary school. A total of 95…

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…

This study aims to demonstrate the optimal way to determine the cut-off score to be used to interpret the total scores obtained from an achievement test or scale using the Artificial Neural Networks method. To this end, the multiple-choice item responses in the Booklet-11 Mathematics subtest at the 8th grade level in the TIMSS 2015 Turkey sample…

Starting at the school level, language education develops comprehension and expression skills. It is important to develop literacy skills as it is the basic way of acquiring information. Native language textbooks created with a text-based approach are an integral part of this process. Accurate, qualified, and purposefully selected texts help…

In this study, in line with TIMSS 2019 data, 8th grade students' school engagement in the Turkish education system and various variables in the field of science and mathematics, which are thought to be related to school engagement, were examined with the Random Forest method, a method amongst data mining methods. This research focuses on student…

E-learning platforms have become increasingly popular in K--8 education to promote student learning and enhance classroom teaching. Student interactions with these platforms produce trace data, which are digital records of learning processes. Although trace data have been effective in identifying learners' engagement profiles in higher education…

Geometry is an important part of the mathematics curriculum. In the late 1950s, Pierre Van Hiele and Dina Van Hiele-Geldof developed a theory of learning geometry. Theory helps determine students' geometric thinking levels, design appropriate instruction for their level, and students move to the next level. This study aims to examine the studies…

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…

Students' socioeconomic status (SES), school climate, and students' attitudes stand out as important factors that determine academic achievement. The current study investigated the relationship among SES, attitude toward science, school climate, and academic achievement comparatively in terms of countries. Trends in International Mathematics and…

In this study, games were prepared that will contribute to improving the vocabulary of children learning Arabic. Considering the target audience, it is known that game techniques and word teaching offer a fun and lively course environment and increase the motivation of the student. In this study, qualitative research methods were used. Document…

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…

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…

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…

The purpose of this study was to investigate the interplays among the critical thinking disposition, cognitive flexibility, math anxiety and math achievement with structural equation modeling and determine the degree of the mediating effect of math anxiety in primary, middle and high schools. Within the scope, we also focused on the predicting…

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…
