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…

This study examined factors that have been shown to predict middle school students' (grades 6-8) task values (utility value related to engaging with science in the future). Using structural equation modeling students' (N = 1015) responses to a career aspiration survey were analyzed to determine relationships among the factors. The model of best…

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…

This study investigated whether students' motivational beliefs about learning science (i.e., self-concept in science and intrinsic value of science) varied significantly across grade levels and genders. The study also examined the relations between students' motivational beliefs about learning science and their science achievement by grade level…

This research was the first research integrating decision making trial and evaluation laboratory (DEMATEL) and structural equation modeling (SEM) to analysis factors, including interest in science, value in science and confidence in science, affecting female students' science achievements from the Trends in International Mathematics and Science…

Girls and women are underrepresented in science, technology, engineering, and mathematics (STEM) fields. Research has investigated various explanatory factors (e.g., lack of role models, sexism) in these patterns. However, to date, the roles of media use and body concerns have not been examined. This study investigated associations among…

The purpose of this study was to investigate the mediating role of 7th grade students' motivation toward learning science in the relationship between their science learning environment perceptions and science achievement. The correlational research design was utilized in this study and data were collected from 922 7th grade students using…

In this systematic literature review, we examined the theoretical frameworks, construct operationalisation, and quantitative results as they relate to student motivation and science achievement in TIMSS studies. Our synthesis of findings derived from an international dataset present notable value in that the patterns identified regarding the…

Trends in International Mathematics and Science Study (TIMSS) is an international comparative study that has been implemented by the International Association for the Evaluation of Educational Achievement (IEA) since 1995. This proposed study is aimed to identify the affective factors contributing to eighth graders' science achievement in TIMSS…

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…

This study aimed to examine the mediating effects of motivational beliefs in the relations between parental involvement and science achievement. Three types of motivational beliefs, namely, self-concept, intrinsic value, and utility value were addressed based on the Expectancy-Value Theory model. A representative national sample from Taiwan of…

The present research aimed to determine the relationship between Jordanian students' 21st century skills (Cs21) and academic achievement in science. The sample of the research consisted of a total of 96 eighth-grade students drawn from four rural and four urban schools in Irbid Qasaba in the governorate of Irbid. Randomly cluster sampling was used…

The present study describes science expectancy-value motivation classes within a nationally representative sample of students who were U.S. ninth graders in 2009. An expectancy-value model was the basis for science-specific profile indicators (self-efficacy, attainment value, utility value, interest-enjoyment value). Using exploratory latent class…

According to the TIMSS 2015 international study findings, students who enjoy learning mathematics a lot scored much higher (average 61 points) than the students who do not enjoy it a lot. Enjoying learning mathematics is one of the indicators of the construct "intrinsic motivation" towards mathematics, and this type of other constructs,…
