Gokhale, Anu A. – Journal of Technology Studies, 1996
Both a control group and experimental group (23 students each) received a lecture on direct current circuits; the experimental group also participated in a lab using a device explaining an analogy for electric current. The experimental group's posttest scores were much higher, indicating that the analogical device helped overcome student…

Hoefnagels, Marielle H.; Rippel, Scott A. – American Biology Teacher, 2003
Presents a collaborative learning exercise intended to teach the unfamiliar terminology of experimental design both in biology classes and biochemistry laboratories. The exercise promotes discussion and debate, develops communication skills, and emphasizes peer review. The effectiveness of the exercise is supported by student surveys. (SOE)

Wellington, Jerry, Ed. – 1998
This book attempts to reflect on the value and purpose of practical work as part of the science curriculum: why are practical exercises so necessary and what do they contribute to the science learning process? The chapters in this book examine issues such as: how practical work is perceived by students and teachers; the possibilities and perils of…

Clement, Russell W.; And Others – Teaching of Psychology, 1997
Replicates a classic psychology laboratory experiment where students either endorsed or refuted personal statements and estimated how other people would respond. Students always overestimated an affirmative response on the statements they endorsed, thus illustrating the false consensus effect. Includes a list of the statements and statistical…
