Described is a study which was developed to find the proportion of cross-dominance in young adults. Procedures and statistical tests are discussed. The tasks used in the assessment of cross-dominance are described. Results indicated that all persons suffered from some cross-dominance. (CW)

Summarizes the report on undergraduate education in biology published by the National Science Foundation. Discusses the problems and recommended solutions for each of three areas: laboratories and course development; enhancing the quality of teaching; and recruitment and retention of students. (YP)

Points out that research is an inefficient endeavor as it relates to time, but the rewards can be gratifying and of value. Reports on a compilation of faculty and administration observations, alumni and student surveys, and some readings on the topic. (RT)

Introduces an interdisciplinary activity using a cola drink. Describes the lesson plan, including objectives, procedures, evaluation, projects, and conclusions. Provides two laboratory sheets containing problem, hypothesis, materials, procedure, observations, and conclusions, vocabulary table, and data table. (YP)

Describes a method for demonstrating absorption spectra of intensely colored solutions using a mounted grating and a specially designed cell. Allows a student to compare the spectrum of a white light source directly with the same light modified by an absorbing spectrum. Uses acrylic tubing to make the cell. (MVL)

Reviews research on the purpose and effectiveness of laboratory activities. Discusses epistemology, problem solving, cooperative learning, student involvement, assessment, and teachers as researchers. (YP)

Describes apparatus for Doppler demonstrations. Provides several pictures of the apparatus and ways it could be used. (YP)

Discusses the equipment and techniques for taking photographs using a sound-actuated trigger. Describes a method using two flash units, two sound triggers, and a high-frequency clock to measure speeds. Provides several high-speed photographs. Lists 11 references. (YP)
