Activities for calculating experimental and theoretical probabilities are presented. Worksheets designed for duplication for classroom use are provided. Suggestions are given for additional problems that could be generated from the original simulation, and answers to questions on the worksheets are included. The activities simulate parachute…

Geometric construction problems are recommended as sources of stimulating exercises for mathematics classes. (MP)

The Concept Game, which focuses on the attributes of parity, balance, majority, closure, and skip of seven-digit binary numbers, is described. Originally written as a computer program, the game is modified so that pupils can play with construction paper chips of just paper and pencil. (MP)

Practical tips on the teaching of subtraction, addition and subtraction of fractions, and finding the vertex of a parabola are given. (MK)

Presents an analysis of student science projects at science fairs that judges are likely to encounter. Presents a challenge to the organizers of science fairs to define the goals of the fair and the criteria for selecting winners. The problems associated with the process are discussed. (SA)

Describes a test designed to measure outcomes of "inquiry" social studies programs in elementary schools. Results indicate that inquiry students, or those whose teachers use inductive methods to encourage active participation in learning, perform better than noninquiry students on tasks requiring higher cognitive processes. (Author/KC)

Three examples are given illustrating the use of the calculator in problems where determining patterns and making conjectures are stressed. (MP)

A program to help children become aware of the biological interdependence of living things is being introduced into Swedish preschool programs. Program background and focus on discovery learning are discussed. For journal availability, see SO 505 539. (AV)

Traces influences on a university lecturer's choice of teaching method, drawing evidence from his private journal and the work journals of his students. Concludes that the theory-based use of experiential learning is hypocritical and may be promoting false theory. Proposes an alternative discovery approach in which students and lecturers are…

Supports the approach for young children that allows them to perform actions on objects and observe the reactions. Describes some techniques to use to encourage an inquiry approach. (DDR)

Describes a study that compares the performance of introductory physics students on two examination problems. One problem is qualitative and similar to those used in an inquiry approach. The second problem is a typical quantitative problem. Those students enrolled in the inquiry-based introductory course performed significantly better than those…

Discusses strategies to help primary students understand geometric concepts. Highlights best examples, concept cards, defining shapes, discovery lessons, and expository lessons. Presents action research ideas. (JRH)

Recommends phasing as an effective approach for training future science teachers in inquiry-based teaching. The phasing philosophy originated with middle school science teachers and is presented in four phases. (DDR)

Explores the results of a study that involved qualitative analysis of students' reactions to a long-term inquiry experience in a freshman biology course. (DDR)

Describes how raising monarch, black swallowtail, and mourning cloak butterflies in a kindergarten class garden can provide opportunities for observation experiences. Includes detailed steps for instruction and describes stages of growth. Excerpts children's journal dictations to illustrate ways to support the discovery process. Describes related…
