Students often perceive school science as purely theoretical, overloaded with facts, and mostly disconnected from their school, home, and community life. One way to bridge the disconnection between school science and lived experiences, and support students in realizing the relevance of science to their everyday life, is by enabling them to…

It is widely recognized that we need to prepare students to think with data. This study investigates student interactions with digital data graphs and seeks to identify what might prompt them to shift toward using their graphs as thinking tools in the authentic activity of doing science. Drawing from video screencast data of three small groups…

Floating and sinking (FS) is a key topic in science education, both at primary and secondary levels. The interpretation of FS phenomena, however, is challenging due to the difficulty of the scientific concepts and explanatory models involved (e.g., density, buoyancy), along with students' everyday experiences, which conflict with scientific…

All over the world, educational science outreach programs in which students can perform laboratory work have been developed. A common goal of these programs is to counteract students' decreasing motivation in STEM education. In Germany, several outreach science labs have been established over the last 20 years. It is assumed that the…

Science teachers' beliefs about teaching and learning are a vital component of teachers' professional competence and are often assumed to impact classroom practice. To date, these beliefs have been predominantly investigated regarding teaching and learning in general or for a particular science subject (e.g., physics). It remains to be determined…

Previous research has noted one's knowledge of and attitudes toward the theory of evolution is negatively predicted by one's political ideology, specifically how conservative the individual identifies, and positively predicted by one's level rational thinking. The present research expands on this past research by examining the roles of political…

Powerful online visualizations can make unobservable scientific phenomena visible and improve student understanding. Instead, they often confuse or mislead students. To clarify the impact of molecular visualizations for middle school students we explored three design variations implemented in a Web-based Inquiry Science Environment (WISE) unit on…

This study examines cognitive and social processes in group interactions that shape collaborative learning in science classrooms. Three small groups of students were observed while working collaboratively on explaining the burning of a candle under a jar. The learning environment served as a context for examination of conceptual convergence, a…

Involves students in a study designed to examine the interaction between children's observations of light and shadows and their developing theories in the context of a series of lessons in a third-grade classroom. Results suggest that student's observation of light led to the development of a limited theory about light that was largely useful in…

Uses the Science Process Skills Inventory (SPSI) to analyze student efforts at writing experimental designs. Results indicate that explicit, incremental development of the science process skills of formulating hypotheses and identifying variables, together with model examples, may be a means to facilitate student success in designing science…

Establishes the extent to which practical work in South African high schools varies with respect to factors such as gender of student, type of school, medium of instruction, and examination board. Investigates the relationship between experience of experimental work and pupil attainment as measured by matriculation grade. (Author/GA)

Examines the relative importance of middle school students' explicit knowledge and tacit knowledge in carrying out open-ended laboratory investigations. Results indicate the students (n=207) provided with explicit knowledge through instruction performed significantly better in overall achievement in such investigations than those using only tacit…

Presents a study involving students (n=46) enrolled in an introductory physics course designed to describe and understand students' experimenting and problem-solving strategies in a constructivist learning environment. Concludes that students should be provided with problem-rich learning environments in which they learn to investigate phenomena of…

Summarizes comparisons of self-reported interest by gender and experimental condition for middle school students (n=101) who performed scientific experiments under conditions designed to vary across difficulty levels, social contexts, and scenarios of fantasy to realism. Findings indicate that boys were more attentive to aspects of experimental…

Tests in each science area were developed around six laboratory tasks. Students had to plan an investigation, collect and organize data, and formulate conclusions based on calculations and graphs. Over 1,000 students from 32 Ohio schools formed the sample for this study. Data are presented by skill and by task. An analysis for gender and school…
