Questionnaires from students passing the General Certificate of Secondary Education (GCSE) that explored attitudes to dissection and using animals in product testing administered to (n=469) students ages 14-15 showed a high level of support for peers who object to dissection, although objectors are likely to be met with derogatory comments,…

Presents an activity in which college chemistry students collaboratively identify chemical substances. (MKR)

Focuses on the provision of meaningful counterintuitive experimental evidence for students while taking into account the relations of theory, instruments, and experimental data. Discusses the use of experiments designed to test pupils' conceptual framework during the teaching of introductory electricity. (JRH)

Presents activities that use marine organisms with plant-like appearances to help students build classification skills and illustrate some of the less obvious differences between plants and animals. Compares mechanisms by which sessile plants and animals deal with common problems such as obtaining energy, defending themselves, successfully…

Identifies and defines the student practice of "fudging" which involves faking, fabricating, or stealing data. Identifies factors contributing to and motivations for this behavior in (n=6) high school students. (Author/MKR)

Presents an experiment that demonstrates conservation of momentum and energy using a box on the ground moving backwards as it is struck by a projectile. Discusses lab calculations, setup, management, errors, and improvements. (JRH)

Presents an experiment to study the acceleration of a cart moving up and down an inclined plane. Demonstrates how multitiming and the study of the movement in both directions allows the determination of the component of gravitational force along an inclined plane without any assumptions about friction. (JRH)

Presents and analyzes an example from the literature on genetics studies in order to highlight the difficulties in classifying biological materials and the personal equation that finds its way into the measurement. (JRH)

Presents activities to teach the concept of projectile motion to high school students using a spring-loaded dart gun, carbon paper, meterstick, ruler, white paper, tape, and a student's desk. (JRH)

Investigation of (n=31) physics students' analysis of videodisc-recorded images with treatments over an extended time found no significant learning difference between using simultaneous-time and delayed-time analysis for student understanding of kinematics graphs. (Author/MKR)

Describes methods to redevelop lab activities for use in schools with limited resources for proper facilities and equipment. Discusses take-home labs, paper-and-pencil labs, and lab station activities. (JRH)

Reports the use of a heavy duty hacksaw blade and a 1000 turn pick-up coil to form the basis of a mechanical oscillator for a laboratory exercise in mechanical resonance designed for either the elementary undergraduate course or in association with an upper level mechanics course. (LZ)

Research with couples requires measurement and data analytic techniques extending beyond those typically used with individuals. Measurement issues in couples' research that influence subsequent approaches to data analysis are reviewed, with emphasis on issues of nonindependence in couples' data. Univariate and multivariate analyses of…

It is argued that reports of evaluation activities often leave much to be desired because they fail to portray the real trial-and-error processes of the research study and do not report on the logic in use at the time of the inquiry. (SLD)
