Recent years have seen a substantial growth in research that probes children's ideas about natural phenomena. This paper places that research in a context which enables comprehension of how it informs and influences the practice of science education. To this end, past, present, and future styles of research are considered to: (1) demonstrate links…

Examined is how research informs and influences the practice of science education. Discussed are past focuses on treatments, present focuses on students' ideas, and developing styles of research. (YP)

The broad focus of this study was on the role students' existing conceptions play in the process of constructing and understanding mechanics concepts. The study was a naturalistic one, conducted over a number of years, at all grade levels, in one all-boys secondary school in Australia. In particular it was concerned with identifying and…

This paper details how memory protocols obtained in individual interviews may be translated to scores on several dimensions suggested by White. White's nine dimensions are: (1) extent, (2) precision, (3) internal consistency, (4) accord with reality, (5) variety of types of element, (6) variety of topics, (7) shape, (8) ratio of internal to…

This paper reports an action study of conceptual change in mechanics using an instructional strategy based on a constructivist view of learning. The aims of the study were to determine: (1) what effect the instructional strategy had on achieving conceptual change; (2) what devices or strategies students used in their attempts to understand…

Argues that Venn Diagrams are powerful probes of students' understanding of the meanings of terms and the relations between concepts. Examples of the various classroom contexts in which the diagrams can be used are provided. (JN)

One of the clear findings of recent research on the learning of science has been that students who have completed science courses commonly use conceptions held before instruction to interpret natural phenomena. This paper reports on a study of conceptual change in mechanics with particular concern with the nature of student awareness of any…

In considering implications for teaching and learning found in research, a number of writers have urged teachers to probe students conceptions before teaching a concept. The purpose of this probing is to allow the teacher to begin instruction from the conceptual position or positions of the students. This approach carries with it the assumption…
