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…

Research shows that motivation is a critical precursor to students' science achievement. However, research on the topic yields ambiguous results in different cultural contexts. While the positive association between motivation and science achievement has been evidenced universally, the relatively predictive effect and strength of different…

In this study, we investigated the relationships between three pivotal factors that influence student performance, including opportunity-to-learn (OTL) factors, which included proximal indicators that represent science-specific learning opportunities, student motivation (propensity factor), and crucial student and teacher antecedent factors by…

Our research aims to predict students' academic performance by considering the variables affecting academic performance in science courses using the deep learning method from machine learning algorithms and to determine the importance of independent variables affecting students' academic performance in science courses. 445 students from 5th, 6th,…

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…

The study aims to investigate how confidence in mathematics/science, amount of books in the home, gender, whether a student likes being in school, and computer software predicted mathematics and science achievements of students in the Trends in International Mathematics and Science Study (TIMSS) 2019. The sample of the study consisted of…

This study investigated student and classroom level variables related to student science achievement by using the Trends in International Mathematics and Science Study (TIMSS) 2015 dataset. Multilevel modeling was applied in this secondary analysis to examine how science self-concept, school relatedness, and science teaching quality predicted…

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…

A hotly debated topic is the effectiveness of inquiry-based instructional practice in science classrooms on student achievement and motivation. Numerous studies based on multinational large-scale education data show such student-centered instructional practice positively led to students' motivational beliefs but was negatively associated with…

The individual problem-solving (IPS) and collaborative problem-solving (CPS) have received a lot of attention, yet little research has been conducted to investigate whether CPS and IPS are equally effective in improving students' understanding of physics concepts, problem-solving abilities, and minimizing achievement gaps. Therefore, the present…

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 study investigated gender disparities in students' science motivational beliefs, conceptualized as self-concept and intrinsic value, from Grades 4 to 8 in 22 countries. The gender-specific relation between science motivational beliefs and achievement was also scrutinized. Data from the 2011 and 2015 national cohorts of the Trends in…

Current studies reveal that meta-level variables are very important in learning; however, little research has been devoted to the role of metaconceptual and meta-affective variables on student achievement. With the aim of filling this gap in the literature, the present study investigated the relationship between metavariables (metaconceptual…

The purpose of this study was to examine eighth-grade students' science performance in terms of two test design components, item format, and cognitive domain. The portion of Taiwanese data came from the 2011 administration of the Trends in International Mathematics and Science Study (TIMSS), one of the major international large-scale assessments…

The authors designed and conducted this study using the predictive analytics to determine the different science performance predictors of the first batch of K to 12 curriculum in Valencia District, Valencia, Negros Oriental. The authors had chosen three kinds of predictors namely; student-related predictors, teacher-related predictors, and…
