States that the shift in meaning of the Periodic Table to represent regularities in the electron distribution in the shells of atoms can result in confusion between elements and atoms. (DDR)

An appreciation of the relationship between novice and expert knowledge frameworks may help develop an understanding of the process of transition from one to the other. Recommends the use of concept mapping. (DDR)

Considers the idea that concept mapping has applications beyond those associated with student assessment. Outlines further uses for concept mapping in the classroom along with suggestions for implementing this powerful tool. (DDR)

Examines quantitative models in school physics, looking particularly at the degree to which they match the real world. Explores the positive aspects of a mismatch between models and real world conditions. (DDR)

Considers the strategies of peer group review and concept mapping, both of which faculties in higher education might employ in partnership with schools to reestablish the fundamental role that subject matter knowledge has in science teaching. (DDR)

Shows how box diagrams and AVOW diagrams may be used to solve problems concerning networks of resistors that obey Ohm's Law. Presents outcomes and feedback from students and teachers. Concludes with suggestions as to how these techniques might be incorporated into the teaching of basic circuit theory. (Contains 22 references.) (DDR)

Describes a project in which student teachers chose science exhibits and created webpages to communicate some aspect of the underlying science in the exhibit. Student teachers participating in the project developed personal understanding of some difficult areas in science. (DDR)
