Describes a series of experiments designed for general chemistry in which the students prepare metal complexes which are then used as samples for spectral study. (SLH)

Describes a technique of quantitative analysis based on measuring the temperature change accompanying a quantitative reaction in solution. Can be used for delta-H measurements and quantitative determinations by comparison of data obtained for an unknown with that obtained for a series of standards. (SLH)

Describes a procedure for freeing an element from either a mineral or organic matrix with the use of a radioactive tracer to determine recovery of the elements. (SLH)

The study reported here had two main aims: to collect data relating to verbal participation in 'conventional' tutor-led groups and to examine the feasibility of using leaderless groups in university teaching. (Author)

The main features of a general-purpose experimental language are described, followed by an account of its implementation. (Author)

This paper describes a program whereby elementary school children are allowed to select their own reinforcement for performing a specified behavior (reading). An evaluation of the program shows significant improvement of reading ability. (RWP)

Discusses the general design and operation of a quantitative analysis laboratory which is relevant to the student's career objectives and provides reliable and objective criteria for judging student performance. Included are a list of core experiments and a description of student responses. (CC)

Presents a series of activities which focus on the study of the physical characteristics of water, including temperatures, opacity, pH-values, oxygen concentrations, reagents, and free CO2 concentrations. Indicates that ponds can provide the students with opportunities to learn chemistry, geology, biology, botany, and the effects of weather. (CC)

The study investigated the learning and attitudes of individuals in an individualized computer-assisted instruction (CAI) setting using a specially designed group CAI program to permit the entry and evaluation of responses from each group member. Results suggest that individuals in groups learn as well as individuals working alone with…

Article focused on the achievements of the Lea Green School for maladjusted children. (Editor/RK)

Describes an experiment in which rat adipose tissue samples are exposed to labeled glucose; insulin is added to one sample. Subsequent scintillation counting demonstrates the ability of insulin to facilitate the entry of glucose into the tissue. (MLH)
