Defines public choice theory as the application of economic analysis to the study of government, focusing on individual behavior. Contends that the teaching of public choice theory helps students to think critically and analyze political problems. Suggests how to introduce the theory in the classroom and provides three case study handouts. (GG)

Discussed is the case for problem solving in mathematics classrooms. The characteristics of "good" questions are identified. The assessment of questions and questioning techniques is considered. (CW)

Presented is a example that shows why a certain technical lemma is necessary for a valid proof of Galois Theory. The usual proof of Galois' Theory is included as well as one using the lemma. (KR)

Presented is an alternate way to derive R from Taylor's Theorem without involving the (n + 1)st derivative of f. Included is the procedure for estimating the bounds of R. (KR)

Described is a way to use knots to relate a three-dimensional object to a two-dimensional representation of the object. The results are used to produce an algorithm or rule to explain a general case. Included are examples, diagrams, procedures, and explanations. (KR)

The described activities give children an opportunity to use geometric ideas to reinforce arithmetic concepts and to use arithmetic ideas to generate geometric figures (both circles and polygons). (MNS)

Presents four lesson plans for teaching K-12 students about public sculpture and contemporary sculptors. Highlights the following works: "Playscapes" by Isamu Noguchi, "The Dallas Piece" by Henry Moore, "Old Glory" by Mark di Suvero, and "Face of the Earth" by Vito Acconci.

Offers constructive suggestions to social studies teachers on specific ways to present social studies content. Contends that educators must develop strategies based upon student needs--strategies that help teachers link students to the people, places, and things that make up the social studies. (MS)

Discusses classroom projects developed jointly by students and teacher in a sixth grade gifted class. Describes projects involving ghost stories, science research, interviewing authors, the local telephone book, and holiday celebrations. (DHP)

Assignment projects for high-achieving ninth graders were developed, and a comparative evaluation study indicated that they were effective. It bacame clear that teachers needed more practical support, so a diagnostic study was undertaken, leading to the establishment of a link between a categorization of student difficulties and a hierarchy of…

Examines the use of a storyline approach to integrated learning and provides a detailed example. The "Mysterious Encounters--Earth" program based on a detective storyline includes an intensive environmental experience at a local park and provides the springboard and framework to help teachers integrate environmental learning into…

Notes that many activities in early childhood classrooms offer opportunities for sensory learning that may be overlooked unless specific attention is directed toward these areas of learning. Suggests that teachers can increase these opportunities by using "feely" boxes or bags, which allow children to touch an object without seeing it. Various…

Features math activities for primary and intermediate grades. Presents four math activities teachers can use to get students interested in, and excited about, math. The titles of the activities are "Date Problem,""What's the Price?,""Krypto," and "Baby Krypto." (ET)

Presents three computer activities that can help students learn mathematics concepts and clarify their thinking: LOGO programming, creating presentations to teach the solution of certain mathematical problems to other students in the class, and writing in order to explain their mathematical thinking. The activities provide immediate feedback,…

Describes the use of a "Rube Goldberg machine contest" to help students learn physics. (PR)
