This study capitalizes on response and process data from the computer-based TIMSS 2019 Problem Solving and Inquiry tasks to investigate gender differences in test-taking behaviors and their association with mathematics achievement at the eighth grade. Specifically, a recently proposed hierarchical speed-accuracy-revisits (SAR) model was adapted to…

The aim of this study is to develop a theoretically sound, valid, and reliable scale to examine seventh and eighth grade students' attitudes towards so-called skill-based mathematics questions (SBMQ). The sample of the study was 820 seventh and eighth grade students at three different middle schools in Etimesgut District of Ankara Province. A…

It is well understood that when students are experiencing hunger, their ability to learn suffers. What is less understood is why this is the case and the role of the learning environment. Using Trends in International Mathematics and Science Study (TIMSS) 2019 data, this brief examines how student hunger is correlated with how disorderly the…

This study focused on the relationships between teacher characteristics and students' mathematics achievement in EU countries, including Hungary, Italy, Lithuania, Malta, Slovenia, Sweden, and Turkey, which are the only EU countries participated in TIMSS 2015 at the eighth-grade level. The data consisted of the sample of 31,969 eighth-grade…

This study examines the factors affecting the mathematics achievement of 8th-grade students in Türkiye using data from the TIMSS in 2011, 2015, and 2019. The data were analysed with multilevel (two-level) modelling. The first level was the student, and the second level was the school. At the student level, such affective characteristics as…

This study aims to develop a valid and reliable achievement test to measure the achievement of eighth-grade students in the "Seasons and Climate" unit of the science course. The research was carried out using a survey model. The study group consists of 298 eighth-grade students studying in various cities in Turkey in the 2020-2021…

Unfavorable test-taking behaviors, such as speededness and disengagement, have long been a validity concern for large-scale low-stakes assessments. Understanding the presence and extent of such behaviors is important for ensuring the validity of inferences based on test scores. This study examined test-taking behaviors using item response time…

Good learning devices greatly assist teachers in conveying the process of seeking knowledge to students. This study aimed to develop a STEAM-C (Science, Technology, Engineering, Art, Mathematics and Culture) integrated learning device in Masjid Kuno Taman, Indonesia to improve students' creative thinking skills. The learning devices included…

The ultimate aim of this research was to explore the contribution of teacher preparedness or readiness (in terms of their academic background, confidence in teaching science and career satisfaction) towards the achievement in science among Malaysian and Singaporean eighth-graders. The TIMSS 2011 international assessment of student achievement at…

Trends in International Mathematics and Science Study (TIMSS) 2019 data revealed that Grade 8 science teachers in several Asian countries (Chinese Taipei, Hong Kong SAR, Japan, and South Korea) reported lower job satisfaction levels than the international average. For example, while Japanese Grade 8 students ranked among the highest in science…

We investigated two research questions: which students are more likely to respond inconsistently to mixed-worded questionnaire scales, and which country samples have larger shares of inconsistent respondents? We defined an inconsistent response as strongly agreeing or disagreeing with both positively and negatively worded items of the same scale.…

National and International standardized assessments have shown sharp differences between native and foreign students' performance in both text comprehension and mathematics. Based on the data gathered yearly by the INVALSI (Italian National Institute for the Evaluation of Educational Systems) at the national level, we performed a two-step…

In Slovenia, textbooks are an integral part of the curriculum. Nationally certified textbooks guarantee both teachers and students that they provide all of the necessary knowledge in each subject. There are many available certified textbooks for each subject and teachers must decide which will be the source of instruction for their students. Our…

Background/purpose: Teachers play a critical role in student learning processes and in their academic success, and as such their job satisfaction directly impacts upon their teaching efficacy and lecture quality. In light of the importance of job satisfaction in educational practice, this study investigates the impact of work environment factors…

Nearly 14 million species are estimated to exist on Earth, of which 1.8 million have been identified, and new species are being added to the world of science every day. Therefore, scientists are aware that there are still unidentified species living globally. Biodiversity is a wide concept encompassing all living things in our living space. This…
