Describes two laboratory exercises adopted from current research papers for use in an undergraduate developmental biology course. Gives methods, summary of student results, and student comments. Lists lecture topics, text and reprint assignments, and laboratory exercises for course. (EB)

Discusses the role of laboratory work in biology and suggests reasons (mostly related to the preparation of teachers) for the continuing emphasis on confirmatory laboratory exercises rather than student directed investigations. Gives examples of process and affective objectives, and practical suggestions for using behavioral objectives to guide…

Reports on experimental comparisons between the leopard frog, currently captured for laboratory use, and the African clawed frog, raised specifically for research. Except for the increased longevity of isolated nerve axons in the clawed frog, no other significant differences were established. Recommends laboratory use of clawed frogs as…

Reassess the influence of the Commission on Undergraduate Education in the Biological Sciences (CUEBS) upon current undergraduate biology instruction, 20 years after making its findings public. Emphasizes the importance for the new generation of biology educators to reattempt the achievement of CUEBS goals despite past failures. (24 references)…

Presents an active-learning technique in which students design their studies that was found to be successful in an animal behavior laboratory course. Divides the laboratory course into three components: (1) structured and technique-oriented exercises; (2) open-ended and student-designed investigations; and (3) independent projects. Explains…

Reviews the work of the Commission on Undergraduate Education in the Biological Sciences (CUEBS) from 1964 to 1972. Suggests that now is the appropriate time to reassess their efforts, to build on their successes, and to use their experience to attack some of the continuing problems facing biology education.
