Described are integrated science and mathematics activities that focus on gathering, displaying, and interpreting data on balloons. Students are involved in sampling, taking polls and surveys, doing experiments, classifying, estimating, and measuring. Included are directions, extensions, and activity sheets for students and parents. (KR)

Provides a first experiment for college chemistry that provides insights into scientific procedures without presupposing any detailed knowledge of chemistry on the part of the student. Requires the student to measure successive masses and volumes and use these values to determine the density from the slope of the graph. (MVL)

Describes results of a survey of the use of computer-assisted learning (CAL) in distance education in Australia. Highlights include subject areas that use CAL; software specifications; types of hardware used; students' and instructors' perceptions of computer usage; and suggestions for further research. (13 references) (LRW)

Investigates ground state electron configurations for some common elements using graphical methods. Bases observed tendencies on following ideas: "occupancy of differing shells, occupancy of differing subshells within a given shell, double occupancy vs. single occupancy of an orbital, and quantum-mechanical exchange." (ML)

Discusses research findings related to students' ability to make connections between analytical (symbolic) and graphical representations of functions in calculus. Describes graphing tasks and typical student interpretations. Implications for teaching are suggested. (Contains 17 references.) (MKR)

Presents a lesson plan detailing an interdisciplinary mathematics/science activity in which students take a home survey of light bulbs and then design an energy-saving lighting system for a home. Contains reproducible student worksheets. (MKR)

This survey of 510 special education teachers found that most teachers collect, record, and use data on student performance to determine instructional effectiveness, appropriate time to move students to the next skill, and which objectives have been met. Only one-third of teachers used graphs for displaying and interpreting data. (Author/JDD)

Presents year-long, elementary science projects that address the question of why daylight hours vary in length according to locality. Provides three instructional units designed to commence in September, including data collection activities for sunny days encouraging later classroom calculations; on-going graphing activities; and modeling…

Presents five charts and graphs drawn from the latest "Bowker Annual" that show the average cost of books, periodicals, textbooks, videocassettes, and cassette tapes for elementary and secondary school libraries from 1979-89. (LRW)

Presents a lesson plan for illustrating how shifting patterns of immigration and public reaction have influenced public policy toward immigration restriction. Details objectives and procedures for activities using National Archives documents. Includes a worksheet and copies of government documents. (CH)

Investigated the effects of studying an ecological system via computer simulation on 14- and 15-year-old students' (n=9) abilities to pose hypotheses; control and manipulate variables; and learn via icon, graph, and table display formats. Working with a simulation encouraged students to think hypothetically and test their hypotheses by controlling…

Presented are student activities that involve two standard problems from geometry and calculus--the volume of a box and the bank shot on a pool table. Problem solving is emphasized as a method of inquiry and application with descriptions of the results using graphical, numerical, and physical models. (JJK)

This review of the introductory instructional substance of functions and graphs analyzes research on the interpretation and construction tasks associated with functions and some of their representations (algebraic, tabular, and graphical). The nature of learning is analyzed in terms of intuitions and misconceptions. (TJH)

Analyzes video recordings of postgraduate seminars in the Arts Faculty at a South African university in order to define the nature of this practice in South African tertiary institutions. This article exposes these seminars as sites of competition for the floor with significant imbalances in participation by different groups, reflecting different…
