Knowledge is not simply a collection of facts, principles, and formulas; instead, meaningful knowledge is organized around core concepts that guide peoples' thinking about a subject. Therefore, knowledge organization is recognized as an important component of understanding learning and teaching. In this research, knowledge organization of two…

In this study, the Trends in International Mathematics and Science Study 2007 data were used to build mathematics achievement models of fourth graders in two East Asian school systems: Hong Kong and Singapore. In each school system, eight variables at student level and nine variables at school/class level were incorporated to build an achievement…

In this study, we investigated elementary student teachers' scientific habits of mind for a series of socioscientific issues, and compared their views with respect to academic performance and type of programme. The sample consisted of 1,600 student teachers from science education, mathematics education, primary teacher education and social…

We compared the materialization of knowledge integration processes in class discussions that followed troubleshooting (TS) and problem-solving (PS) tasks and examined the impact of these tasks on students' conceptual understanding. The study was conducted in two sixth-grade classes taught by the same teacher, in six lessons that constituted a…

The aim of the study was to discover the contribution of students' interest in school biology, as well as their self-efficacy and attitudes towards different science subjects and mathematics when explaining students' orientation towards biology-related careers at upper-secondary school. The data of 321 K-11 students (49% women) were…

For over two decades, there has been increasing concern regarding the science learning of disadvantaged students such as indigenous or disabled students. The academic achievement of students with hearing impairment has been seen as relatively low. This low achievement has been mainly due to students' poor literal ability and not because of…

This study used phenomenography, a qualitative method, to investigate Taiwanese mathematics teachers' conceptions of school mathematics, school statistics, and their differences. To collect data, we interviewed five mathematics teachers by open questions. They also responded to statements drawn on mathematical/statistical conceptions and…

This study investigated students' understanding of a virtual infectious disease in relation to their understanding of natural infectious diseases. Two sixth-grade classrooms of students between the ages of 10 and 12 (46 students) took part in a participatory simulation of a virtual infectious disease, which was integrated into their science…

The purpose of this study was to assess Greek primary (1st to 6th grade) school children's dietary habits and the factors influencing them. Our results show that children know the value of different foods. The socio-economic status of father has no effect on the attitude of children towards choosing their diet, however, mothers' educational status…

This case study examines the alignment between the Intended Curriculum, Implemented Curriculum and Achieved Curriculum of a fourth grade inquiry based unit, "Food Chains and Webs." Specifically addressed are how the curriculum was modified to meet state standards, how teachers were trained, and how assessment of curricular implementation was…

This exploratory study investigated data-gathering behaviors exhibited by 100 seventh-grade students as they participated in a scientific inquiry-based curriculum project delivered by a multi-user virtual environment (MUVE). This research examined the relationship between students' self-efficacy on entry into the authentic scientific activity and…

While the knowledge economy has reshaped the world, schools lag behind in producing appropriate learning for this social change. Science education needs to prepare students for a future world in which multiple representations are the norm and adults are required to "think like scientists." Location-based augmented reality games offer an…

This study examines the patterns of use and potential impact of individualized, reflective guidance in an educational Multi-User Virtual Environment (MUVE). A guidance system embedded within a MUVE-based scientific inquiry curriculum was implemented with a sample of middle school students in an exploratory study investigating (a) whether access to…

The research presented in this paper consisted of an investigation of the effectiveness of a four-step constructivist-based teaching activity on student understanding of how pressure and temperature influence the dissolution of a gas in a liquid. Some 44 Grade 9 students (18 boys and 26 girls) selected purposively from two school classes in the…

In spite of advances in physics pedagogy, the lecture is by far the most widely used format of instruction. We investigated students' understanding and perceptions of the content delivered during a physics lecture. A group of experts (physics instructors) also participated in the study as a reference for the comparison. During the study, all…
