In this paper, we applied a number of clustering algorithms on pretest data collected from 264 high-school students. Students took the pre-test at the beginning of a 5-week experiment in which they interacted with an intelligent tutoring system. The primary goal of this work is to identify clusters of students exhibiting similar knowledge…

The purpose of this research was to examine the effects of implementation of argumentation in a physics classroom on students' reasoning. This research is both quantitative and qualitative in nature. Experimental design was used for the study. For the quantitative aspect of the research, students' prior knowledge in the beginning of the…

The effects of students' misconceptions, declarative knowledge, and stimulus conditions on students' solutions to a problem in basic electricity were studied for 80 undergraduates at Iowa State University (Ames). The implications of the findings of influence by knowledge and stimulus conditions are discussed. (SLD)

A study examined the relationship between two variable sets: (1) epistemological beliefs (Quick Learning, Simple-Certain Knowledge, and Innate Ability) and performance goals; and (2) conceptual understanding and application reasoning in conceptual change learning. In addition, effects of different kinds of prior knowledge on conceptual change…

The purpose of this research study was to explore the effects of children's trade books on the development of science concepts. The two objectives of this exploratory study were to determine whether children's ideas about specific science concepts change when trade books containing information about those concepts are read to them, and…

A number of strategies, informed by science education research, have been identified to assist the understanding and communication of difficult concepts in science. A teacher's craft lies in creating learning experiences that facilitate concept development and challenge misconceptions from which students actively build, modify, and extend their…

Research has established that students generally possess conceptions relevant to curricular topics before they begin to study them and that these preconceptions often persist despite instruction on scientific theories which contradict them. Discrepancies between students' post instruction conceptions and the scientific theories as taught often…
