Tested was the hypothesis that science instruction based on task analysis will lead to the acquisition of the ability to perform certain Piaget volume tasks which have been characterized as requiring formal operations for their solutions. A Test on Formal Operations and a Learning Hierarchies Test were given to fourth- and sixth-grade students in…

Experiment compares the effect of equilibration type training to the effects of S-R reinforcement type training in developing weight-conservation concepts in second and third grade pupils. S-R group performed significantly better than control group on initial posttest for conservation of weight. A measure for permanence of the conservation beliefs…

THE RELATIVE EFFECTIVENESS OF TWO TYPES OF MECHANICAL MODELS FOR TEACHING ELEMENTARY SCHOOL STUDENTS TO USE THE PARTICLE IDEA OF MATTER TO EXPLAIN CERTAIN PHYSICAL PHENOMENA WAS INVESTIGATED. SUBJECTS WERE RANDOMLY SELECTED FROM STUDENTS ENROLLED IN GRADES TWO THROUGH SIX IN A SCHOOL SYSTEM. A SERIES OF DEMONSTRATIONS AND RELATED QUESTIONS WERE…

REPORTED IS THE DETERMINATION OF THE RELATIVE EFFECTIVENESS OF TWO METHODS OF INSTRUCTION IN TEACHING CLASSIFICATIONAL CONCEPTS OF PHYSICAL AND CHEMICAL CHANGE TO ELEMENTARY SCHOOL CHILDREN. THROUGH TEACHER-DIRECTED DEMONSTRATION-DISCUSSION, STUDENTS IN GRADES 2-6 WERE INSTRUCTED IN THE CONCEPTS OF PHYSICAL AND CHEMICAL CHANGE WITH THE…

Aimed at elementary school science teachers, this presentation has as its major focus the idea that science teaching should make sense. Language used in verbal communication should be precise, experiences provided for children should be logically related and geared to the child's level of cognitive development, and the materials used should…

THE EFFECT OF PLANNED GUIDANCE ON THE PROBLEM-SOLVING BEHAVIOR OF ELEMENTARY STUDENTS WAS INVESTIGATED. FACTORS RELATED TO CHANGES IN PROBLEM-SOLVING BEHAVIORS WERE IDENTIFIED. APPROXIMATELY 50 PERCENT OF THE SIXTH-GRADE STUDENTS INCLUDED IN THE STUDY WERE GIVEN INQUIRY TRAINING 30 TO 60 MINUTES DAILY FOR 3 WEEKS. AN INVENTORY OF SCIENCE PROCESSES…

Paper delivered at the American Association of Physics Teachers meeting in New York City, February, 1967.

Reports study of children in grades two through six to determine concept formation achievement about chemical and physical change. Performance of three tasks by two groups at each grade level after thirty-minute lessons on five consecutive days are used for evaluation. Researcher concludes that these concepts are attainable by sixth graders and…

Reports on a replication study to determine the relative effectiveness of two methods of instruction in teaching classificatory concepts and to determine whether maturity of children was related to level of understanding. (GS)
