Error in science is a prime occasion to teach the nature of science, especially the central feature of tentativeness. Error types also reflect corresponding methodologies of science, critical for practicing science and (in a context of scientific literacy) analyzing its claims. Effective efforts in teaching about error will ideally be informed by…

To explore the ways in which teacher-guided and student-centered instructional approaches influence students' conceptual understanding of seasonal change, we designed a technology-enhanced learning (TEL) course to compare, by means of concept maps, the learning outcome of students in two groups: a teacher-guided (TG) class (with whole-class…

Explores the effectiveness of concept mapping, the learning cycle, expository instruction, and a combination of concept mapping/learning cycle in promoting conceptual understanding of diffusion and osmosis. Concludes that the concept mapping/learning cycle and concept mapping treatment groups significantly outperformed the expository treatment…

Investigates high-achieving fifth-grade students' achievement gains and conceptual reorganization on convection. Features an instructional sequence of three dyadic inquiry investigations related to convection currents as well as pre- and post-assessment consisting of a multiple-choice test, a card sorting task, construction of a concept map, and…

Reports results of metanalysis of 19 studies on concept mapping (CM) in science instruction. Results showed CM has positive effects on student achievement and attitudes. Differences in achievement depended on science content class, with biology being most favored. Smaller differences in achievement were found when CM groups were compared to a…

Investigates the role of talk, writing, and talk and writing on the learning and retention of simple and integrated knowledge, and describes the mechanisms by which talk and writing mediate these processes. Suggests that talk is important for sharing, clarifying, and distributing knowledge among peers, and writing is an important tool for…

Describes a study designed to compare student success in a concept mapping exercise with the cognitive preference of the student, and to determine whether students achieve better using individualistic or cooperative learning modes in the concept mapping exercise. Discusses the background, methodology and results. (CW)
