A study was conducted to determine the relationship of visualization abilities to achievement in chemistry. Two freshmen and one senior level class of chemistry majors were included. Two visualization tests and a chemistry examination at the end of the semester were conducted. A stronger relationship was reported between senior chemistry status…

Differences in the biology curricula of two-year and four-year colleges pose many problems for both students and teachers. A program to coordinate all biology teachers throughout the state for resolving such differences is described. (PS)

Describes a one-semester junior course with emphases placed on students' use of instructions designed by their peers in doing laboratory exercises, and indicates the feasibility of such a plan to a rather small range of group sizes. (CC)

Describes redesigning of a genetics course on the basis of Pella's referents, Banathy's system, and Bloom's taxonomy in effort to evaluate affectively behavioral changes among reference groups of science and nonscience majors, in addition to genetics students. Indicates preference of learning environment to course content in results analysis. (CC)

Presents an outline of the 1973 program and a summary of science education issues including curriculum developments at the graduate level. Discusses the controversy existing during hearings between the Foundation and the Committee on Science and Astronautics and between Congress and the Administration. (CC)

Describes a simple and inexpensive apparatus which can be easily constructed and which provides a highly visible example of an apparently reversible reaction for undergraduates. (DF)

Knowledge about gene defects (such as the Sickle Cell Gene) should be given to those who show positive laboratory tests. Conflict between gene therapy, aimed at removing the defective gene, and ethical problems should be resolved from the perspective of the effect on future generations. (PS)

A three week field-centered program was initiated to study ecological concepts relating to the sea, mountains and forests on a 5,000 mile route. Students travelled and camped at sites along the route. Evaluation of the program and the students was comprehensive. (PS)

Describes various techniques for conical chromatography together with advantages and disadvantages. (DF)

Studied the superiority of audio-tutorial instruction among 79 students by using the pretest-posttest control group design, and concluded the absence of significant difference in achievement analyses both between the control and experimental groups and varying-aptitude subgroups. (CC)

This transition, observed with an inexpensive ultraviolet photometer, is a potentially useful experiment for an advanced freshman class because it introduces several concepts of general physical interest. (DF)
