This research applied the learning strategies to predict in an effect longitudinal growth of cognitive structure of students in biology. The aim of the research is to assess the effect of activating learning strategies on cognitive structures regarding biology. The research was conducted by using control group design. The sample of research was…

Differences in the status of ontological categories on the concept maps of secondary-, undergraduate- and graduate-level chemistry students were analyzed with the "Pathfinder" scaling algorithm and multidimensional scaling. Results indicate differences among groups in the structural significance of abstract process-related nodes and…

This study presents a quantitative method for scoring concept maps generated by students learning introductory college chemistry. Concept maps measure the amount of chemical information the student possesses, reasoning ability in chemistry, and specific misconceptions about introductory and physical chemistry concepts. They provide a visualization…

Discussed is the relationship of concept-mapping by students to the meaningful learning of genetics and ecological concepts. The implications of these results for teacher education in biology are addressed. (KR)

A longitudinal study of students' developing understanding of decimal notation has been conducted by testing over 3000 students in Grades 4 to 10 up to 7 times. A pencil-and-paper test based on a carefully designed set of decimal comparison items enabled students' responses to be classified into 11 codes and tracked over time. The paper reports on…

Concept maps are visual representations of knowledge structure and thought. Not enough attention has been paid to the measurement and influence of preservice teachers' knowledge structure and its development over time. This study implemented instructional scaffolding interventions in order to determine the effect on preservice teachers' knowledge…

Hypermedia as a learning environment complements traditional instruction as it places the student at a higher level of control. Instead of "wait and see" what the teacher expects the student to learn next, hypermedia stimulates the student to become aware of his/her own cognitive needs and interests. This paper presents a combination of notions…

Summarizes current developments in alternative frameworks research in science education. Covers concept maps, learning as conceptual change, classroom strategies, problem solving in physics and where research should be going. (CW)

The use of concept maps, Vee diagrams, flow charts, and productive questions to increase student understanding of laboratory exercises and to improve student attitudes toward lab classes is discussed. Examples of each are provided. Student responses to these teaching methods are described. (CW)
