The aim of this study was to investigate the development of metacognitive strategy knowledge (MSK) during schooling at the upper secondary education level and to examine its relation with individual student characteristics. This longitudinal study with two measurement points analyzed a sample of students in grades 10 and 11 from 19 schools…

Visualizing the chemical structure and dynamics of particles has been challenging for many students; therefore, various visualizations and tools have been used in chemistry education. For science educators, it has been important to understand how students visualize and represent particular phenomena--i.e., their mental models-- to design more…

"University of Chicago School Mathematics Project" ("UCSMP") is a core mathematics curriculum that emphasizes problem solving, real-world applications, and the use of technology. The curriculum is based on a student-centered approach with a focus on active learning that incorporates reading and uses a flexible lesson…

This research examined the effectiveness of a design-based, continuous professional development (CPD) programme intended to promote teachers' self-confidence and teaching reflection skills. The CPD was associated with teacher implementation of theoretically devised, motivational, context-based, inquiry teaching modules, based on a justified…

Math anxiety has been the focus of much psychological and educational research in the past few years, there are many international studies showing that mathematics anxiety is an influence on student's achievements in school, but little research has been done about this issue in Bahrain. Bahrain is a country in the Arabian Gulf region, its economic…

Based on cognitive load theory, the effect of different levels of instructional detail and expertise in a simulation-based environment on learning about concepts of correlation was investigated. Separate versions of the learning environment were designed for the four experimental conditions which differed only with regard to the levels of written…

Anxiety and self-efficacy are among the factors that impact students' performance in biology. The current study aims to investigate high school students' perception of biology anxiety and self-efficacy, in relation to gender, grade level, interest in biology, negative experience associated with biology classes, and teachers' approaches in the…

The majority of research on the link between video games and aggression has focused on the violent content in games. In contrast, recent experimental research suggests that it is video game competition, not violence, that has the greatest effect on aggression in the short-term. However, no researchers have examined the long-term relationship…

Lay conceptions of energy often conflict with scientific knowledge, hinder science learning and scientific literacy, and provide a basis for ungrounded beliefs. In a sample of Finnish upper secondary school students, energy was attributed with features of living and animate beings and thought of as a mental property. These ontologically confused…

Students from low-income families consistently trail behind their peers in retention and degree attainment. Research on college student experiences suggests that low-income students experience "cultural mismatch" at college--they feel that their backgrounds are at odds with the middle-class values dominant on campus (Armstrong &…

This paper reports on the design and enactment of an instructional strategy aimed to support students in constructing scientific explanations. Informed by the philosophy of science and linguistic studies of science, a new instructional framework called premise--reasoning--outcome (PRO) was conceptualized, developed, and tested over two years in…

Little empirical data are available concerning the cognitive abilities of gifted individuals in general and especially those who excel in mathematics. We examined visual processing abilities distinguishing between general giftedness (G) and excellence in mathematics (EM). The research population consisted of 190 students from four groups of 10th-…

This research study examines the assumptions of creating bilingual scenarios to promote English language learning for 384 students of ninth, tenth and eleventh grade of a public school in Monteria Colombia. An action research methodology was carried out in this study. The findings of this research suggested that the creation of bilingual scenarios…

We present a new system for automated scoring of graph construction items that address complex science concepts, feature qualitative prompts, and support a range of possible solutions. This system utilizes analysis of spatial features (e.g., slope of a line) to evaluate potential student ideas represented within graphs. Student ideas are then…

Thermal cameras offer real-time visual access to otherwise invisible thermal phenomena, which are conceptually demanding for learners during traditional teaching. We present three studies of students' conduction of laboratory activities that employ thermal cameras to teach challenging thermal concepts in grades 4, 7 and 10-12. Visualization of…
