We describe the development, design, implementation, and preliminary classroom results of an innovative curriculum, "Focus on Energy," that supports learning about energy in Grades 4-5. The curriculum is grounded in the concepts of science as practice, model-based reasoning, and learning progressions, and builds on students' pre-existing…

Considers teaching as an activity in which teachers deliberate in the practical domain to decide on actions and goals. Argues that because practical reasoning is similar to scientific reasoning, a model of practical conceptual change can be developed that is analogous to the conceptual change model. Examines two case studies of teachers using the…

Describes the nature and existence of both model-data fit and conceptual problems in science, then examines two curricular projects--one in genetics and one in evolutionary biology--that attempt to integrate these problems into classroom instruction. (Author/SAH)

Presents a rationale for providing preschool children with experiences related to classification, seriation, and pattern recognition because they are means by which a child can organize the world around him. These are considered to be the early steps in the long developmental sequence leading to logical thinking and reflective observation. (GS)

Analyzes the meaning of Piaget's concept of abstraction and provides discussion of some of its shortcomings. (HM)

Analyzes how educators currently frame historical stories to portray the process of science. Discusses the importance of narratives of error and recovery from error in illustrating the nature of science and its limits. Emphasizes history that conveys the nature of science effectively. (Author/KHR)

Advocates the educational theories of David Ausubel as a basis on which to build science and mathematics curricula and instructional procedures. Offers interpretations of Piaget's conservation tasks in Ausubelian theory. (CP)

Describes a study in which teaching and learning activities are designed using a cognitive conflict strategy. Focuses on the effectiveness of these activities in classroom research in pre-university courses in Botswana and South Africa. Contains 39 references. (DDR)

Examines the impact of one unit of a curriculum module for sixth grade from the Model-based Analysis and Reasoning in Science (MARS) project. Provides an overview of this unit on mass and discusses three aspects of the evaluation of the unit. Contains 22 references. (DDR)

Discusses the meaning of Schwab's "substantive structures" of a discipline in terms of science philosophy. Presents three techniques for representing substantive structures and discusses some of their uses in science education research. (SK)

Investigated the development of children's concepts of the earth utilizing the Piagetian interview method to collect data from a sample of 240 children coming from grades four to eight of an experimental public school in Jerusalem, Israel. (HM)

Presents a study that examines the beliefs of teachers (N=24) and their interpretations of a two-week summer institute intended to change their treatment of scientific knowledge and assessment strategies at the classroom level. Contains 31 references. (DDR)

This research assessed Australian high school students' understanding of light, developed materials to conceptual change with respect to the concept, and evaluated the effectiveness of teaching strategies utilizing the materials. After instruction, students were able to construct significantly more scientifically acceptable answers. An appendix…
