This study investigated the relationships of teacher-directed approaches with science achievement in Australian schools. The data for this study were drawn from the Program for International Student Assessment (PISA) 2015 database and analysed using multilevel modelling (MLM). MLMs were estimated to test the contribution of each item to students'…

Background: A solid foundation in science is critical to students' success in the 21st century workforce, especially in fields related to science, technology, engineering, and mathematics (STEM). Therefore, high-quality science education is critical to prepare students for the challenges of the future. However, Emirati students have consistently…

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…

The study examined the impact of students' absolute age-position at the time of testing by grade level and gender on their achieved level of mathematics, reading and science performance. An analysis was conducted based on a sample of 11,500 15-year-old pupils in the United Arab Emirates who participated in the OECD's Programme for International…

This study, drawing on data from the third cycle of the Program for International Student Assessment (PISA) and employing three-level hierarchical linear modeling (HLM) as an analytic strategy, examined the relations of inquiry-based science teaching to science achievement and dispositions toward science among 170,474 15-year-old students from…

Drawing on data from the fifth cycle of the Program for International Student Assessment (PISA), the authors examined the relations of reported acculturation orientations--heritage as well as host culture-orientations--and perceived cultural distance between host and heritage culture with academic performance among 399 first- and second-generation…

This study, drawing on data from the Trends in International Mathematics and Science Study 2007, examined the predictive effects of multiple dimensions of mathematics and science self-concept--positive affect toward mathematics and science and self-perceived competence in mathematics and science--on mathematics and science achievement among 1,752…

This study explored the predictive effects of science self-beliefs on science achievement for 24,680 13-year-old students from Gulf Cooperation Council member countries--Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates--who participated in the Trends in International Mathematics and Science Study (TIMSS) 2007. The…

This study, drawing on data from the Trends in International Mathematics and Science Study (TIMSS) 2011, examined whether mathematics teachers' perceptions of their students' mathematical competence were related to mathematics achievement, affect toward mathematics, and engagement in mathematics lessons among Grade 8 students in Singapore and…

This study, employing hierarchical linear modeling (HLM), sought to investigate the student-level and school-level factors associated with the science achievement of immigrant and non-immigrant students among a national sample of 22,646 students from 896 schools in Canada. While student background characteristics such as home language, family…

This study, drawing on data from the Trends in International Mathematics and Science Study (TIMSS) 2007, examined the influences of self-perceived competence in mathematics and positive affect toward mathematics on mathematics achievement of adolescents in Singapore. Ordinary least squares (OLS) regression analyses revealed the positive influences…

The author sought to investigate the effects of inquiry-based science instruction on science achievement and interest in science of 5,120 adolescents from 85 schools in Qatar. Results of hierarchical linear modeling analyses revealed the substantial positive effects of science teaching and learning with a focus on model or applications and…

This study examined the effects of motivation to learn science, science self-beliefs, and science instructional practices on science achievement of 13,985 15-year-old students from 431 schools across Canada. Hierarchical linear modeling (HLM) analyses, while controlling for student- and school-level demographic characteristics, revealed the…

Background: The Trends in International Mathematics and Science Study (TIMSS) assesses the quality of the teaching and learning of science and mathematics among Grades 4 and 8 students across participating countries. Purpose: This study explored the relationship between positive affect towards science and mathematics and achievement in science and…
