Outlines the rationale, resources, and techniques for teaching K-12 physical science via toys. Includes 65 references and a list of 9 mail order suppliers of scientific toys. (MDH)

Describes the use of concept mapping and Vee diagramming in helping students learn how to learn. (PR)

Use of concept mapping as an assessment tool allows links to be made between concepts, and shows both scientifically correct propositions and misconceptions. Annotated drawings offer an alternative form of expression to children who may hold ideas but find it difficult to express them in words or to recognize links between them. (PVD)

Evaluates the ultimate goals of environmental and ecological education. Examines two versions of an established outdoor ecology program in a national park. Surveys students (N=700) using knowledge statements. Contains 64 references. (DDR)

Presents student comments as they explain their mathematical reasoning and thinking about place value in addition and subtraction. (ASK)

Discusses recent studies related to conceptual understanding in the domain of history, comparing the nature of understanding as found in history to that of other domains. Considers the role of sources in historical knowledge, the role of the historian, causation and explanation, and narrative exposition. (MJP)

Focuses on three students engaged in a group task to develop a concept map on hypermedia-related concepts. Examines how each of the students--grouped together based on their learning style and cognitive control differences--influenced construction of the group concept map. Concludes that the "Assimilator/Field-Independent" student was the most…

Contends that developing computer displays of dynamic motion offers a means to help students understand complex chemistry concepts. Describes how to set up a computer animation team, gives an example of the animation of chemical processes in a standard hydrogen electrode, illustrates how to teach with animations, recommends hardware and software…

Investigates whether and how collaborative learning at the computer fosters conceptual change. Employs a suite of computer-simulation programs developed to confront students' alternative conceptions in mechanics. Contains 46 references. (DDR)

Explores changes in students' (n=250) thinking about basic chemical ideas during a context-based curricular approach. Suggests that 16- to 18-year-old students enter chemistry courses with a wide range of misunderstandings about chemical reactions, but understanding improves steadily as the course progresses. Concludes that even misunderstandings…

Describes students' (n=175) understandings of the structure of animal (including human) skeletons and the internal organs found in them. Finds that older students have a better knowledge of animals' internal anatomies, although knowledge of human internal structure is significantly better than knowledge of rat, bird, and fish internal structure.…

Used interviews and observations of teachers and students to examine how historical concepts and research strategies were taught and learned in two fourth grade classrooms. Found that teaching method differences were obvious but student differences in concept- and strategic-knowledge development were subtle. Both teachers were partially successful…

Describes a study that investigated the relationship and development of fifth-grade students' conceptual ecologies of heat. Contends that relying on a single mode of assessing students' learning can lead to a restricted view of what they truly know. (WRM)

Analyzes a teaching episode to determine how a conflict is perceived and overcome by students as a result of verbal interaction between the teacher and the students. Discusses the particulate nature of matter with students aged 15-16 after observing a glass of water containing a rock and an ice cube. (Contains 25 references.) (Author/YDS)

Reviews and assesses the effectiveness of the attempts undertaken to improve prospective and practicing science teachers' conceptions of the nature of science (NOS). Categorizes reviews as implicit or explicit. Indicates that the explicit approach was more effective in enhancing teachers' views. Assumes that developing an understanding of NOS is…
