According to the ACT theory of skill acquisition, cognitive skills are encoded by a set of productions, which are organized according to a hierarchical goal structure. People solve problems in new domains by applying weak problem-solving procedures to declarative knowledge they have about this domain. From these initial problem solutions,…

CLOSED CIRCUIT TELEVISION WAS WELL RECEIVED BY DENTISTRY STUDENTS AT NEW YORK UNIVERSITY BUT FAILED TO YIELD SIGNIFICANT GAINS IN ACHIEVEMENT OVER CONVENTIONAL INSTRUCTION. TWENTY-ONE NULL HYPOTHESES WERE TESTED ON 154 MALE SOPHOMORE STUDENTS, WHO WERE DIVIDED INTO GWO GROUPS, HALF BEING INSTRUCTED TO A LARGE EXTENT VIA CCTV, TV CLASS, AND HALF…

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 investigated (1) the extent to which thinking and problem-solving of fifth-grade students could be improved by the use of self-instructional programed lessons (the productive thinking program), (2) the relationship between productive thinking abilities and IQ-sex characteristics of the learner, and (3) the relationship between level of…

This bibliography, made up of approximately 350 entries concerned with many aspects of problem solving and concept formation in young children, has been designed for use by people primarily involved in experimental research in these areas of child development. Entries include experimental journal articles, conference papers, unpublished research…

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.…

The SACI project in Brazil has as a main target the country's primary teachers. The SACI Project objectives are: (1) to test the efficiency of an educational program using audiovisual media (particularly television, radio, and slow scan) at the primary level; (2) to develop television production techniques; (3) to train teachers in the utilization…

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…

An experiment tested the efficacy of "discovery learning" in a school setting. Fifty-two bright children ages one to seven were randomly divided into two groups: a discovery learning, non-directed group and a guided learning, teacher-directed group. After both groups had spent eight months using an individualized "talking…

Factors which influence the acquisition of a second language within the framework of the British educational system are examined in this study. An ongoing, 10-year, language experiment (1964-74) involving 18,000 students ranging in age from 8 to 13, concentrates on determining the desirability and practicability of starting modern language…

Explores the selection, source, funding, time constraints, and community support involved in developing carefully planned and executed science projects. Lists 21 kinetics experiments noting the instrumentation needed and the original references. (MVL)
