Many studies have characterized students' difficulties in understanding and reasoning about scientific mechanisms. Some of those studies have drawn implications on teaching mechanisms and how to guide students while reasoning mechanistically. In this theoretical article, I claim that one component that has not garnered much attention in the…

This study explores the impacts of selected early science experiences in kindergarten (frequency and duration of teachers' teaching of science, availability of sand/water table and science areas, and children's participation in cooking and science equipment activities) on children's science achievement in kindergarten and third grade using data…

Epistemic criteria are the standards used to evaluate scientific products (e.g., models, evidence, arguments). In this study, we analyzed epistemic criteria for good models generated by 324 middle-school students. After evaluating a range of scientific models, but before extensive instruction or experience with model-based reasoning practices,…

This research investigated the effect of reflective discussions following inquiry-based laboratory activities on students' views of the tentative, empirical, subjective, and social aspects of nature of science (NOS). Thirty-eight grade six students from a Lebanese school participated in the study. The study used a pretest-posttest control-group…

This study investigated the development in students' nature of science (NOS) views in the context of an explicit inquiry-oriented instructional approach. Participants were 18 seventh-grade students who were taught by a teacher with "appropriate" knowledge about NOS. The intervention spanned about 3 months. During this time, students were engaged…

Discusses preliminary research on a new heuristic tool for learning from laboratory activities in secondary science. Finds that use of the science writing heuristic facilitated students in generating meaning from data; making connections among procedures, data, evidence, and claims; and engaging in metacognition. (Contains 29 references.)…

The purpose of this article is to report findings from an ethnographic study that focused on the co-development of science literacy and academic identity formulation within a third-grade classroom. Our theoretical framework draws from sociocultural theory and studies of scientific literacy. Through analysis of classroom discourse, we identified…
