Discusses classroom demonstrations of classical conditioning and notes tendencies to misrepresent Pavlov's procedures. Describes the design and construction of the conditioner that is used for demonstrating classical conditioning. Relates how students experience conditioning, generalization, extinction, discrimination, and spontaneous recovery.…

We present a practical for university-level students aimed at measuring and comparing xylem hydraulic properties of co-existing plant species. After sampling branches of several woody species in the field, their main hydraulic properties were measured using a simple set-up. Hydraulic conductivity ("K[subscript h]") was calculated as the ratio…

A recent team-teaching experiment at Redhill Technical College is described presenting the problems, aims, results, and some reflections on the future. (MW)

An educational performance contracting project illustrates difficulties of satisfactory implementation as intended when examining climate for the experiment, its design and results, and problems of carrying out the project. (Author/ND)

A series of educational experiments are being conducted in Canada on the Communications Technology Satellite. The description of these experiments reveals a diversity not previously encountered in educational applications of satellite systems. In evaluating these experiments, the authors adopted Stufflebeam's Context-Input-Process-Product model in…

A SPEECH THERAPY METHOD FOR MENTAL RETARDATES WAS DEVELOPED AND EVALUATED. THE METHOD WAS BASED UPON THE ESTABLISHMENT OF FAVORABLE ASSOCIATIONS IN THE CHILD BETWEEN THE WORDS AND SOUNDS OF LANGUAGE AND THE PRODUCER OF THE LANGUAGE, USING STIMULUS-REWARD AND SITUATION-REWARD PRINCIPLES. TRADITIONAL METHODS OF SPEECH THERAPY WERE ADMINISTERED,…

The Radio Mathematics Project was established to design, implement, and evaluate a prototype system of teaching elementary mathematics using radio as the major medium of instruction. The project, working in rural and urban primary schools in Nicaragua, presents daily mathematics lessons in second and third grade classrooms. Each lesson has a 30…

THE PROGRESS OF THE RESEARCH AND DEVELOPMENT (R AND D) PROGRAM IN VOCATIONAL-TECHNICAL EDUCATION DURING THE FIRST 18-MONTH CONTRACT PERIOD IS SUMMARIZED, AND PROJECTIONS ARE MADE REGARDING ITS FUTURE OPERATION. THE R AND D PROGRAM IS ROOTED IN THE CLINICAL APPROACH TO TEACHER EDUCATION AND PROGRAM EXPERIMENTATION. THIS APPROACH UTILIZES THE…

The Ohio State Instructional Preference Scale (OSIPS) was designed to identify persons suited or not suited for teaching. After identifying six areas covered in general secondary methods courses, two researchers independently constructed a series of statements representing attitudes, ideas, and dispositions about each area and jointly constructed…

An experiment was conducted to determine which of three modes of instruction controlling the "density" of simulation training was most effective in terms of transfer and most efficient in terms of the learning rate of preservice teachers. Four goals of the classroom simulation were identified and practiced in three training modes: (1)…

A number of potential threats to internal validity in true experiments are discussed. Programmatic research efforts proceeding from established correlational findings to experiments employing random assignment are described and used as referents in discussions of validity considerations. The collection of observational data is recommended for use…

This basic aim of this paper is to explore and describe how the results of experimentation are transmitted from the "laboratory" campus to other campuses and to propose ways of improving and expanding the dissemination process. Chapters cover: (1) New College as a model, (2) "new" elements in New College's program, (3) the…

Critical of the language instruction which students receive in elementary and secondary schools, the author examines the teaching potential of televised instruction. Foreign language instruction in the elementary school is noted to be particularly weak. Discussion of an experiment involving some 800 children in 4th and 5th grades suggests that…
