Reported is a study to investigate the effects of a free-choice program on children's ability to interpret experiments, design simple investigations, and recognize variables that could affect the outcome of observed events. (Author/SA)

This study describes children's learning in a free-choice environment. Teacher controlled instruction is minimized and children participate in a wide variety of science activities with equipment that is selected by each individual student. The study occurs within an elementary school's Science Enrichment Center and the children work on the…

This paper reports a study designed to examine the types of behaviors students exhibit while conducting laboratory activities and assess the effectiveness of strategies students employ. The sample was 42 students enrolled in a physics lab section at a single university. Three types of data were collected: (1) observational data during the lab…

Tests in each science area were developed around six laboratory tasks. Students had to plan an investigation, collect and organize data, and formulate conclusions based on calculations and graphs. Over 1,000 students from 32 Ohio schools formed the sample for this study. Data are presented by skill and by task. An analysis for gender and school…

Uses base-year data from a nationally representative database (NELS:88) to identify important explanatory factors for gender differences in science performance. Documents a large advantage for boys on the subtest of physical science and a modest advantage for girls in life science. Concludes that laboratory experiences are beneficial for girls'…

Examines features of science experiments that make them interesting to middle school students (n=59 seventh graders). Compared a model of interest in learning with the reasons students gave for liking experiments. Latent partition analysis was used to derive an empirical model from characteristics of interesting science experiments. (PR)

A science teacher and her mentor reflect on their participation in the Learning Research Cycle, a professional learning model that bridges research and practice in both university and public school contexts. Teachers do scientific research in scientists' laboratories, then bridge their scientific experiences with the design of new classroom…
