The effectiveness of four methods of speech instruction with third and fourth grade culturally deprived boys and girls was compared. The methods of instruction varied in regard to the manner in which they were developed and in sophistication from simple instructions on the operation of audiovisual equipment and materials to a commercially…

The basic problem of this study was to develop a method for increasing the efficiency of the instructional process at the introductory level. The experiment compared two methods for doing the outside of class assignments in support of a course in library science instruction. The plan called for the control groups to do the outside assignments in…

This speech discusses the planning for and the implementation of the O.E.O. performance contracting experiments. The author argues that it was not performance contracting, but the O.E.O. experiment which failed. The author blames this failure not so much on the poor evaluation design, but rather on the number of interface problems which arose…

CERTAIN SPECIFIC ASPECTS OF HYPOTHESIS TESTS USED FOR ANALYSIS OF RESULTS IN RANDOMIZED EXPERIMENTS WERE STUDIED--(1) THE DEVELOPMENT OF THE THEORETICAL FACTOR, THAT OF PROVIDING INFORMATION ON STATISTICAL TESTS FOR CERTAIN EXPERIMENTAL DESIGNS AND (2) THE DEVELOPMENT OF THE APPLIED ELEMENT, THAT OF SUPPLYING THE EXPERIMENTER WITH MACHINERY FOR…

AN EXPERIMENTAL SITUATION WAS DEVELOPED IN WHICH THE SUBJECT HAD THE TASK OF DETERMINING WHICH OF A SET OF POSSIBLE EVENTS HAD OCCURRED ON EACH TRIAL. THIS WAS DONE BY ASKING THE EXPERIMENTER QUESTIONS WHICH COULD BE ANSWERED "YES" OR "NO" UNTIL THE EVENT WAS NAMED. FOUR EXPERIMENTS WERE CONDUCTED IN WHICH STRATEGIES WERE…

This study involving ninth-grade algebra students investigated whether learning in environments identified in previous research as effective (i.e., exhibiting high levels of learner involvement) elicit significantly higher levels of relevant achievement than do ineffective learning environments.

A study of computerized conferencing and its effects on human communication was conducted via an investigation of EIES and its users. A summary of the research findings is followed by a discussion of the ultimate objectives and potential advantages of experimentation with EIES in this area. (MBR)

Reports on research concerning the formation, location, and composition of manganese modules. (CP)

Two experiments investigated the effects of a prior-cuing procedure on retention after short intervals. Results indicated that both latency of correct recall and category recall are facilitated by a cue statement administered prior to the recall test. Results are also discussed in relation to spreading-activation models of memory processing.…

Although Tzeng (1973) and Bjork and Whitten (1974) have obtained positive recency effects in free recall using a procedure designed to eliminate any component of short-term storage, their procedures may not have truly cleared short-term storage. This experiment attempts to find whether positive recency would be obtained in a situation without any…

Describes a freshman chemistry experiment in which students separate and identify commonly used drugs by thin-layer chromatography. Materials needed, procedures used, and typical results obtained are included. (JN)

Describes a low-cost ($120) device which eliminates plasma lines in Raman spectra. The device consists of two prisms and two mirrors which are held in a symmetrical relationship to one another so that a particular position will allow only one wavelength to pass through on a given axis. (JN)

Describes an activity that (1) illustrates the classical experiment as a research tool; (2) demonstrates the interplay among hypotheses, methods, and data; and (3) nurtures the excitement of a method of study. (BSR)

Described is a student preparation of YBa2Cu3O8-x, a classroom demonstration of its superconductivity, and an analytical chemistry experiment dealing with the oxidation state of copper in the material. (RH)

Described is a workshop for grades 5-8 school teachers and students related to synthetic polymers. Participants become familiar with polymer theory and practice experiments they can use in class. Sources of materials used in the workshop are listed. (RH)
