Describes eight investigatory science activities that can be used to study concepts related to heat. (PS)

Describes the conducting of three experimental courses by using texts, programmed supplements, lab manuals, behavioral objective sets, study guides, and tutoring and lecturing techniques in instruction. Indicates the feasibility of this model in institutions that can not use strict Keller Plan systems. (CC)

Describes a course developed to change negative student attitudes toward physics. A general outline and contents of the course in practice are included. (DF)

Twelve ideas are presented for physics teachers to implement in the laboratory or classroom. Topics covered include electromagnetic induction, microbalance, capacitors, determination of light velocity, and the compound pendulum. Information regarding laboratory equipment is also provided. (PS)

Presents the results of two Piagetian conservation tasks administered to high school students. It was found that not many were at the formal operations level. Similar evidence is presented for college students. Concludes that development of formal thought must be a focus of all teachers. (DF)

Details of the generator used in a proton-synchrotron particle accelerator are described. (PS)

The ratio of electronic charge to Boltzmann's constant can be easily determined by measuring the short-circuit collector current versus the emitter-base voltage characteristic of a silicon transistor connected in the common-base mode. (Author/DF)
