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…

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…

Serious games have become increasingly available to educators. Empirical studies and meta-analyses have examined their impact on learning achievement. However, natural sciences could have a special relation to serious games by their systematic use of quantitative and predictive models that can generate microworlds and simulations. Since no known…

This study aimed to determine Turkish junior high-school students' perceptions of the general problem-solving process. The Turkish junior high-school students' perceptions of the general problem-solving process were examined in relation to their gender, grade level, age and their grade point with regards to the science course identified in the…

The aim of this study is to develop a valid and reliable instrument to assess why physics courses are perceived as one of the most difficult courses among high school students and to investigate the reasons why students have difficulty in learning physics through this scale. This study includes the development and validation studies of the…

Background: While existing evidence strongly suggests that immigrant students underperform relative to their native counterparts on measures of mathematics, science, and reading, country-level analyses assessing the homogeneity of the immigrant achievement gap across different factors have not been systematically conducted. Beyond finding a…

This country review offers an independent analysis of major issues facing the use of school resources in Portugal from an international perspective. It provides a description of national policies, an analysis of strengths and challenges and options for possible future approaches. The analysis focuses on the process of decentralisation of school…

This compliance report provides information regarding American Indian students' public school performance and how performance is measured. This information is shared with legislators, educators, tribes, and communities and is disseminated at the semiannual government-to-government meetings. The New Mexico Public Education Department (NM PED) is…

This article examines how international differences in age-grade distributions and grade effects contribute to science scores among 27 Organization for Economic Cooperation and Development countries. As shown in the 2006 Program for International Student Assessment, countries vary substantially in the grade distribution of 15-year-olds. The costs…

The investigation reported in this paper was prompted by discrepancies between the published outcomes from two international tests of science achievement: (1) the Second International Assessment of Educational Progress (IAEP2), administered in 1991; and (2) the Third International Mathematics and Science Study (TIMSS), administered in 1995. One…
