This paper describes a multifaceted agitation and mixing experiment. The relatively inexpensive apparatus includes a variable-speed stirrer motor, two polycarbonate tanks, and an instrumented torque table. Students measure torque as a function of stirrer speed, and use conductive tracer data to estimate two parameters of a flow model. The effect…

A set of general principles underlying theory formation, theory revision, and experimentation are described. The manner in which these techniques may be integrated to provide a unified and comprehensive treatment of scientific theory development is demonstrated. In particular, the means by which experimentation is used to empirically guide and…

This experiment uses a radioactive technique to determine the relative leaving abilities of chloride and iodide in nucleophilic substitution reactions. (DT)

Two experiments are described which illustrate preparative as well as mechanistic features of the reactions of halogens with alkanes and alkenes. (DT)

By concentrating radioactivity contained on luminous dials, a teacher can make a high reading source for classroom experiments on radiation. The preparation of the source and its uses are described. (DT)

A description of Paddock School, a school for the severely mentally handicapped, and its special audiovisual program for instruction. (HB)

Noting that in the contemporary world, rhetorical experimentation has proliferated at almost geometric rates, this paper proposes that an understanding of rhetorical variables will help in acquiring an overview and understanding of that rhetorical experimentation. Defining rhetorical variables as all the elements that can take different values in…

In order to test the effectiveness of teaching in modifying moral judgments, 200 students were administered a test of moral judgments in mitigating circumstances. Of the five classes, two received instruction about the authoritarian personality, while three classes served as controls and received no such information. In a pretest-posttest design,…

While there has been much research on psychological factors and drug response, the intensity of the search appears to vary inversely with the potency of the drug studied. There seems to be little replication in the studies. The four studies summarized here involved the same psychological variable measured by an abbreviated version of the Bass…

This is the second in a series of annual presentations on the innovative, experimental, and research activities conducted at Santa Fe Junior College. The studies include: classroom activities, college-wide research, short statements on different instructional approaches to formal dissertation abstracts, subjective observations, intricate…
