Examined effects of contextual and individual differences on mothers' autonomy support versus control on homework-like tasks with their third-grade children. Found that mothers in the high-pressure condition were more controlling on the poem task. For the map task, mothers with initial controlling styles in the high-pressure condition were more…

Reports on a study to discover physics student teachers' objectives for practical work in teaching physics. Participants took a course based on a unique perceptional approach. Results indicate that after attending the course, student teachers found that the practical work which they had done was very useful. (Author/MM)

Describes an unusual course at the University of California, Los Angeles which includes DNA sequencing experiences and exploration of the social, economic, and ethical issues resulting from advances in biotechnology. (EV)

Elementary teachers can use weather folklore to help students explore and discover facts about weather. An experiment with woolly bear caterpillars examines whether their stripes can predict what kind of winter weather there will be. A investigation about moon halos and rain gives students experience setting up investigations based on questions…

Presents a physics lab activity in which students determine if an electrode configuration simulates a section of concentric cylinders or concentric spheres. (WRM)

Explains why one orientation of an asymmetric spring-and-mass system leads to a higher frequency of 0000000000 than another orientation. (WRM)

Describes nine basic experiments that demonstrate the wave nature of light and the optical properties of water. Finds that a laser pointer works well as a light source in the laboratory. (CCM)

Discusses introductory polarized light measurements in which a diode laser pointer replaces the more frequently used polarized helium-neon laser. (WRM)

Discusses the effectiveness of offering science laboratories via distance education. Explains current delivery technologies, including computer simulations, videos, and laboratory kits sent to students; pros and cons of distance labs; the use of spreadsheets; and possibilities for new science education models. (LRW)

Reports on Westfield State College's Animal Behavior course which requires students to design their own research projects, write a scientific research proposal, conduct experiments, and present results in the form of a scientific paper. (Author/MM)

Reports on four experiments and/or activities that were used to stimulate student interest in environmental science. Makes the case that varying classroom activities in the environmental science classroom makes the teaching and learning experience more alive and vital to both instructor and student. (Author/MM)

Demonstrated an experiment on the properties of air to 2 groups of Swedish fourth graders (total n=45), using familiar materials in one case and unfamiliar, "scientific," materials in the other. Written explanations by students show that the unfamiliar materials were a barrier to understanding and may have actually obstructed students'…

Two priming experiments demonstrated exogenous attentional persistence to the fundamental auditory dimensions of frequency (Experiment 1) and time (Experiment 2). In a divided-attention task, participants responded to an independent dimension, the identification of three-tone sequence patterns, for both prime and probe stimuli. The stimuli were…

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 study investigates how 25 junior high school students employed their bodies of knowledge and responded to problem cues while individually performing a science experiment and reasoning about a drops phenomenon. Line-by-line content analysis conducted on students' written ad hoc explanations aimed to reveal students' concepts and their…
