The study reported in this paper, combined qualitative (observation, interview and case study techniques) and quantitative (questionnaire and survey instruments) methods (n=3,182 Grade 10 students). The study (1) examined the relationship of current teaching practices to a number of variables that affected students' learning in science laboratory…

This packet contains four science learning activities that can be used in agricultural education courses. The activities cover these topics: (1) determining the effect of air pressure on fluid flow; (2) how lubrication and oil viscosity affect friction; (3) determining relative strengths of wood fasteners; and (4) determining the effects of…

The Zimbabwe Secondary School Science Project (ZIM-SCI) developed student study guides, corresponding teaching guides, and science kits for a low-cost science course which could be taught during the first 2 years of secondary school without the aid of qualified teachers and conventional laboratories. This teaching guide, designed to be read in…

This life science activity module was designed to facilitate student conceptualization of plant growth. It is intended for use primarily in elementary grades but may be useful at higher grades. It provides students with hands-on experience and observational skill development. The package provides: (1) a teacher background sheet; (2) an activity…

To test the hypothesis that if given a curriculum designed to develop cognitive functioning and taught by strategies designed to develop cognitive skills, students would then master more sophisticated symbolic thought earlier and more systematically than could be expected if this development had been left to the accidents of experience or if…

This study on self-confrontation in teacher training presents the students' repeated assessments of subject-object relations both during the experiment and six weeks and two years after the experiment. For the experiment the student teachers were confronted with their own video-recorded micro-lessons; identification experiences and self-evaluation…

This paper describes an experiment in team teaching involving 25 students in a Spanish language class on the high school level. Team teaching was found to be particularly suited to vocabulary presentation, testing, culture teaching, grammar explanations, dramatization of stories and fables, pronunciation drills, and classroom conversation. It was…

The problems investigated in the present study are the identification of the most effective type of presentation of dialogues in language instruction--auditory, orthographic, or some combination of the two--and the measurement of the accuracy of pronunciation and the amount of dialogue retained by the student. The controlled experiment, performed…

A combination of a progress report and a technical report, this paper should prove useful as an aid in planning future research, and should prove generally useful to those interested in communication processes by means of sound films, as well as to those who work in the areas of radio and television. Effectively there are two halves to the paper.…

This report contrasts the results of a rigidly specified, pattern-oriented approach to learning Spanish with an approach that emphasizes the origination of sentences by the learner in direct response to stimuli. Pretesting and posttesting statistics are presented and conclusions are discussed. The experimental method, which required the student to…

Describes an inservice teacher workshop conducted in Pennsylvania which was designed to encourage the introduction of chemistry at the elementary school level. Discusses the organization and content of the workshop, the materials used, and some evaluative information provided by workshop leaders, teachers, and their students. (TW)

Describes the use of a precalibrated stainless steel thermistor, interfaced with an Apple computer, in chemistry experiments. Discusses the advantages of "instant" temperature readings in experiments requiring that readings be taken at certain intervals. Outlines such an experiment which investigates freezing point depressions. (TW)

Details 26 experiments designed for use in secondary or college science classes. Includes activities for physical and biological sciences. Describes procedures, materials, safety, and analyses appropriate for each. (CW)

Describes a two-week concentrated laboratory course in chemistry offered by Union College (New York) for middle school students. Provides the objectives of the course and a listing of experiments done by the students. Promotes the use of experiential approaches rather than lengthy lectures and discussions. (TW)

Describes three teaching activities used in the Chemistry for Kids program which focus on how esters are chemicals partially responsible for the flavor of foods. Includes a discussion of a demonstration involving role-playing, a set of taste tests, and an activity using chewing gum to investigate odors in food. (TW)
