Some science educators who are interested in conceptual development have considered the phenomenon of student misconceptions and alternative frameworks. Researchers have used a variety of terms to describe the situation in which students' ideas differ from those of a scientist about a particular concept. This digest was produced to briefly…

The reviews of articles contained in this issue have been grouped into those dealing with research related to cognitive development and to instruction. In addition, seven science education researchers have provided responses to critiques of their published research. Included are: (1) an analysis of an article designed to persuade researchers to…

To discover the relationship between cognitive development and writing, a means of assessing writing is needed that reflects accurately changes in the way children write as they grow older. This may be accomplished by using Piaget's characteristics of concrete and formal operations. His framework permits general descriptions of thinking, organized…

Compares the results of surveys done in 1975 and 1985 with Indiana teachers regarding their physical environment and related problems. Results indicated that teachers had limited environmental literacy but had higher marks in 1985 than in 1975. (TW)

Identifies and discusses the epistemological roots of various terms that have been used to describe student conceptions in the literature with a view to suggest which term science eductors should adopt. Argues that "alternative conceptions" is preferable to "alternative frameworks" for use in describing student conceptions in…

Traces change in conception of gravity in a boy from kindergarten until second grade, focusing on the process by which persons restructure ideas that differ from accepted scientific understandings, and acquire scientific ideas. Provides criteria for defining an alternative conception; suggests how conditions in the initial interview may have…

Explores the influences of text structure on students' conceptual change. Case studies were conducted and results showed that individuals used refutational text to change their alternative conceptions and acquire new concepts. Findings indicate that refutational text does cause cognitive conflict. While refutational text is effective for groups,…

Examined is the situation in which pupils invent mathematics on their own and teachers' reactions to this situation. The assimilation of students' original ideas into correct mathematical concepts is discussed. (CW)

Proposes an approach to school laboratory experiences which leads to gradual acquisition of inquiry skills based on the idea of advance organizers. Presents a design which is context familiar and can serve as an introduction to scientific inquiry. Discusses student achievement, and teacher and student attitudes. (CW)

Described are the use of two different tests designed to test for selected inquiry skills. Procedures, tests used, and results in several different countries are presented. Implications for classroom instruction are discussed. (CW)

States that constructivism is a theory of knowledge which asserts that knowledge is not primarily received, but actively built, and that the function of cognition is adaptive and serves the organization of the experiential world. Gives a brief history and discusses impact of the constructivist approach. (RT)

Reviews the logic underlying mathematical induction and presents 10 tasks designed to help students develop a conceptual framework for mathematical induction. (Contains 20 references.) (MDH)

Contrasts recent views of learning and cognition with cognitive learning theories of the late 1950s and early 1960s. Maintains that Jerome Bruner's spiral curriculum approach, still valuable, is not sufficient to explain cognitive development. Proposes a lattice-like cognitive development structure, inviting differing paths of exploration. (CFR)

Children's responses to an alternative model over three lessons were described and their learning assessed in a posttest. Their responses and performances were compared to that of a similar group of children learning through a conventional number line model. The two models were compared from practical and theoretical viewpoints. (Author/CW)

Describes a theoretical framework for the analysis of conceptual change that considers conceptual knowledge as a generative cognitive tool for the creation of more specific mental representations. Argues that a task-oriented interaction between propositional structures and mental models can help learners evaluate the consistency of their…
