Interviews with participants in the Alum Rock Voucher Project revealed that the effects of a voucher system on teachers were varied and profound: greater teacher autonomy but increased responsibilities; more within-program cohesion but increased competition between programs; and greater parent involvement, requiring teachers to improve…

The mathematical solution to a Piagetian experiment involving topological concepts reported in a recent book is labeled as a sham. The correct solution is given and discussed. (MP)

Stresses the importance of teaching the Greek classics so that they both "speak directly to the student" about matters of importance to modern life and provide an initiation into the ancient ways of life out of which they were written. (Editor)

Reports on the pioneering Hammersmith Teenage Project, which attempts to offer delinquents a real alternative to residential care. (Editor)

Tests a curriculum designed to teach fifth and sixth grade students system dynamics thinking, an orientation that is congruent with the fourth and fifth levels of Bloom's "Taxonomy of Educational Objectives: Cognitive Domain".

Describes a two-stage experiment where students play the role of farmers who must select one of four markets (corn, wheat, rice, or soybeans). Demonstrates the process leading to equilibrium in a multimarket setting. Includes an appendix with the farmer profit chart and homework exercises. (CMK)

Uses inexpensive equipment to demonstrate, through factorial design, an interaction between genetics and environment. Provides instructions for introducing and conducting the experiment, reporting that significant results are usually obtained. Notes the exercise is appropriate for experimental psychology, developmental psychology, behavior…

The authors describe a classroom experiment that motivates student understanding of behavior toward risk and its effect on money demand. In this experiment, students are endowed with an income stream that they can allocate between a risk-free fund and a risky fund. Changes in volatility are represented by mean-preserving changes in the variance of…

This article describes how children build increasingly abstract knowledge of linear measurement, emphasizing ways they relate space and number. Assessments indicate children struggle to understand measurement, especially concepts related to complex paths as in perimeter tasks. This article draws on developmental accounts of children's knowledge of…

This study investigates the efficacy of symbolic modeling and role-playing therapy in the reduction of avoidance behaviors. After treatment, role-playing subjects demonstrated significantly less avoidance behavior and lower subjective fear ratings than the modeling or control group subjects. (Author/SJL)

Describes a study designed to challenge the theory that the initial phase of instruction in foreign language should be based on intensive oral practice. (PMP)

The present study was carried out to evaluate the effects of two different but related treatments (feedback and self charting) which are often found in behavioral reading programs but which are usually not a formal part of other tutoring methods. (Author/RK)

Describes an experiment in which the learning contract method was used in a philosophical ethics course and assesses the learning contract method as compared to the discussion method. (Author/PG)

This research investigates stochastic approximation procedures of the Robbins-Monro type. Following a brief introduction to sequential experimentation, attention is focused on formal methods for selecting successive values of a single independent variable. Empirical results obtained through computer simulation are used to compare several formal…

An experiment that proved worthwhile at Lehman College is reported, in which student teams learned how and produced research papers, a requirement in half the courses on the campus. (Editor/PG)
