This research study focused on the knowledge structure of the domain of physics by describing the knowledge of experts, intermediates, and novices. In order to investigate these representations, a reiterative categorization task was employed using novice, intermediate, and expert subjects (N=27). The categories were classified as theory-, model-,…

The purpose of this investigation was to identify and describe the differences in the methods used by experts (university chemistry professors) and nonscience major introductory chemistry students, enrolled in a course at the university level, to solve paired algorithmic and conceptual problems. Of the 180 students involved, the problem-solving…

If education is concerned with imagination, it is important to know how educators perceive the term. For this purpose, an attempt was made to categorize ways in which teachers conceptualize imagination. Responses were obtained in a survey from 120 teachers who were registered in a graduate course on creative thinking. Participants ranged in age…

Proposes a self-instructional strategy training paradigm designed to explicitly teach that the use of heuristic processes and mediational devices can be employed to compensate for age-associated deficits, such as poor problem solving. Format for the procedure was derived from the developmental research of the Soviet psychologists Vygotsky and…

Information about individuals' representations of problems was obtained from studies on reasoning and problem categorization. College students (N=62) participated in a study of the transition from concrete to formal reasoning using the pendulum and chemical yellow tasks. Over a 10-12 week period, 47 students participated in 10 training sessions on…

THE OBJECTIVE OF THIS STUDY WAS TO GATHER AND ANALYZE DATA ABOUT THE PROBLEM-SOLVING PROCESSES OF ELEMENTARY SCHOOL TEACHERS IN ORDER TO DEVELOP AN OPERATIONALLY DEFINED CONCEPT ON THE CRITERIA FOR PROFESSIONAL, HIGH PROFICIENCY QUALITIES IN TEACHERS. THREE QUESTIONS WERE ASKED--(1) WHAT IS AN ELEMENTARY SCHOOL TEACHER, (2) WHAT IS PROBLEM-SOLVING…

IF COMPUTER PROGRAMS ARE TO SERVE AS USEFUL MODELS OF COGNITIVE BEHAVIOR, THEIR CREATORS MUST FACE THE NEED TO ESTABLISH AN INTERNAL ORGANIZATION FOR THEIR MODEL WHICH IMPLEMENTS THE HIGHER LEVEL COGNITIVE BEHAVIORS ASSOCIATED WITH THE HUMAN CAPACITY FOR SELF-DIRECTION, AUTOCRITICISM, AND ADAPTATION. PRESENT COMPUTER MODELS OF COGNITIVE BEHAVIOR…

The activities described in this report are focused on a preliminary investigation of the effects of presenting problems to children without any prior formal problem-solving instruction, on the children's ability to solve the problems, and on their subsequent problem-solving performances. The work was an outgrowth of activities related to the…

Instructional materials used in two pilot studies are presented. Appendix A contains components of the problem-solving bulletin board. Eighteen problems are stated along with suggestions for solving each problem. Problems 1-10 contain questions extending the original problem. Teacher answer sheets are given for problems 4-18. Appendix B contains…

MANY STUDIES HAVE INDICATED THE PRESENCE OF A SLUMP OR INVERSION IN THE PROBLEM-SOLVING EFFICIENCY OF CHILDREN AT THE FOURTH GRADE LEVEL. IT HAS BEEN SUGGESTED THAT THIS MAY BE DUE TO THE INTERFERING EFFECT OF THE FORMATION OF COMPLEX HYPOTHESES BY THE CHILDREN. SINCE A TENDENCY TO RESPOND RAPIDLY WOULD PRESUMABLY INHIBIT THE FORMATION OF COMPLEX…

The purpose of this study was to investigate a proposed model for the acquisition of the concept of displacement volume and to compare two methods of conservation task presentation. A 12-stage hierarchical model for the acquisition of the concept was proposed, based on four primary assumptions: (1) concept attainment can be measured by…

Metatheoretical analysis of Ausubel's Theory of Meaningful Verbal Learning and Gagne's Theory of Instruction using the Dickoff and James paradigm produced two instructional systems for basic statistics. The systems were tested with a pretest-posttest control group design utilizing students enrolled in an introductory-level graduate statistics…

Three extrinsic factors were manipulated in a problem-solving task performed by 80 ten-year-old children of I Q 90-110. The factors were: the presence or absence of the name of the concept given in feedback, specific instructions, and whether the child was allowed to verbalize. The task was a modification of Vygotsky's experiment on concept…

This activities book for lower elementary grades is the second book of a series of six books designed to provide developmental K-12 experiences designed to support the basic environmental philosophy of spaceship earth. The aims of the four activity sections of this book are to aid in developing students to make them more sensitive to their…
