The purpose of this study was to enhance the teaching and learning of matter and its properties for grade 6 students. The development of a conceptual change approach instructional unit was undertaken for this purpose. Pre- and post-concept surveys, classroom observations, and student and teacher interviews were used to collect data. The teaching…

There is on-going international interest in the relationships between assessment instruments, students' understanding of science concepts and context-based curriculum approaches. This study extends earlier research showing that students can develop connections between contexts and concepts--called "fluid transitions"--when studying…

There are infinitely many ways of talking about infinity. The assortment of discourses on learning infinity is infinite as well. When the author says "way of talking" or "discourse," she is concerned with much more than the question of how words are chosen and combined. Ways of talking are not just innocent "auxiliaries" to thinking--they shape…

While research has shown that elementary (K-5) students are capable of engaging in the scientific practice of explanation construction, commonly-used elementary science curriculum materials may not always afford them opportunities to do so. As a result, elementary teachers must often adapt their science curriculum materials to better support…

This qualitative multiple case study explored the conceptual frameworks of two congenitally blind male adolescents on the nature of matter. We examined participants' responses on four tactile investigations focused on concepts and processes associated with matter changes. The matter changes investigated were dissolution, chemical change,…

This article reports a study of coauthor Laura Wright as she learned to teach secondary school grammar in four settings: university teacher education program, student teaching, her first job, and second job. Data for her university program came from Laura's journals and projects from her course work. Data from student teaching and her first job…

Describes the learning processes experienced by six language teachers within the context of a three-year research project in which they worked and in the context of doing their Ph.D.s as research assistants. These processes involved learning specific research skills, understanding teaching practices, development of theory and concepts, links with…

Reanalyzes pretest and posttest interviews from a large classroom study using a situated cognition framework. Concludes that cognition is a dynamic process that changes in different ways over shorter and longer time scales. Contains 40 references. (DDR)

Based on the Kellian view of constructive alternativism (that the meanings of any idea are not fixed, but vary from individual to individual), this paper describes a technique for exploring school children's conceptions of common physical phenomena to allow science educators (1) to appreciate the alternative conceptions of their students and (2)…

Describes the author's personal version of the action research cycle, focusing on two research experiences to point out what can be learned from research involving listening to language learners. Suggests that one can learn in two different and equally important ways; one can learn about the research question studied and about how to improve the…
