Describes a tape-guided field trip that has been used successfully with college biology students in the University of California Botanical Garden. This program enables large numbers of students to make individual biological observations in the field with the aid of a specially tailored, taped guide. (JR)

Describes the methods of individualized instruction and teaching by example as effective tools in chemistry courses to bring disadvantaged students up to an acceptable level of competence. (CC)

Discusses the development of a one-year laboratory course in an effort to provide a link between traditional laboratories devoted to a single area of chemistry and the total involvement of a single narrow research project. Included are outlines of 32-hour lectures and 11 experiments performed in the integrated course. (CC)

Describes the collisional properties as a logically essential component of the ideal gas model since an actual intraparticle process cannot support observable anisotropic velocity distributions without collisions taken into account. (CC)

Describes a new master of science degree program in toxicology at the University of Arizona. Outlines the prerequisites for entering the program, the nature of the courses, and the various vocational fields that graduates will be qualified to work in. (JR)

Discusses the development of a syllabus and a study guide necessary for adequate preparation of high school physics teachers. Indicates that the unified nature of physical science will predominate over separate physics or chemistry courses on the school level in the future. (CC)

Describes the construction and operational procedures of a simple setup which enables undergraduate students to conduct experiments on critical phenomena in gases. Indicates that the experimental features are proved comparable to those of the Reamer and Sage apparatus. (CC)

The purpose of this study was to analyze the effectiveness of long-term, tutorial-type computer assisted instruction (CAI) in high school chemistry. Analysis showed scores of non-CAI students significantly higher than the CAI group. However, CAI students learner material faster. (PS)

A number of suggestions are made for changing the full, sterile environment of a biology laboratory into one which is lively and motivating to students. (JR)
