The Structured Query Language (SQL) forms a substantial component of introductory database courses and is supported by almost every commercial database product. One disadvantage of SQL is that it does not provide a universal quantification construct. Queries that have twisted universal and existential quantifiers can be stunning for students,…

Outlines techniques used in the context of a sixth grade science class to teach database structure and search strategies for science using the AppleWorks program. Provides templates and questions for class and element databases. (Author/YP)

Reviews two software packages, "Solutions Unlimited" and "BASIC Data Base System." Provides a description, summary, strengths and weaknesses, availability and costs. Includes reviews of three structured BASIC packages: "True BASIC (2.0)"; "Turbo BASIC (1.0)"; and "QuickBASIC (3.0)." Explains…

Within-group similarities and between-group differences are used to illustrate the socio-cultural nature of the concept-building process in highly collaborative computer science classrooms. Simultaneously, a social constructivist perspective is used to describe the individual aspects of this development. The study uses written explanations from…

Reports on a study in which a teacher used the collaborative development of a format-free computer database to facilitate knowledge construction in a group of three Year 6 students during a science project. Contains 28 references. (Author/ASK)

Discusses a classroom project for teaching conceptual meanings and functional purposes of the notations and symbols of mathematics. Describes the background of the approach based on Piaget's theory: concrete level, symbolic level, and abstract level. Lists 14 references and 4 suggested readings. (YP)

Presents abstracts of selected papers on computer topics. These include: computers and mathematics education; microcomputers in school science; model for developing elementary school computer science curriculum; computer-oriented pre/inservice training for science and mathematics teachers; using databases to locate information on software;…

Details a rationale for teacher shared information. Outlines possible content to include in such a network. Describes advantages and implications a database might have for teachers. (RT)

Describes a database courseware using the HyperCard program on the subject of human reproductive endocrinology and feedback mechanisms. Discusses some issues concerning database courseware development. Presents several examples of the courseware display. (Author/YP)

Describes the preparation of preservice secondary mathematics teachers in the uses and implications of classroom technology.
