This study assessed the ability of fourth, fifth, and sixth graders and college students to logically include and exclude variables when making inferences about a multivariate "natural experiment" situation. (Author/SB)

The authors demonstrate how the theories of Piaget and Perry can be applied in a framework for developing instructional methods for courses in home economics. They review these theories, suggest ideas for assessing the developmental stage of the student, and discuss strategies for facilitating student development and learning. (CH)

A study of the development of elementary school children's appreciation of riddles was conducted within the framework of the incongruity and resolution theory of humor. (ST)

Portions of this paper were presented at the meetings of the Society for Research in Child Development, Santa Monica, California, March 1969. (MH)

Changes in children's cognitive strategies for solving simple subtractions were studied by analyzing verbal reports given immediately after each problem. The development of children's cognitive processes involved a gradual shift from more primitive and less demanding memory strategies to reconstructive memory processes to retrieval processes.…

The relationship between a student's stated preference for solving a problem and his/her actual problem methodology, concrete or abstract, was studied. Comparisons were made between formal and nonformal students. (MP)

Distinguishes the values of quantitative increments and qualitative shifts with regard to problem solving. Subjects were 136 children ranging from 6 through 8 years and were presented with the standard 3-disc problem to resolve in 3 minutes. Results indicated that qualitative shifts in children's representation of problem space are a crucial…

Three experiments tested 21- and 27-month olds' ability to construct a path to a mentally re-presented goal. After seeing the goal-state configuration of problems, both age groups evinced planning. Demonstration of initial solution step was less effective than goal-state exposure. Even with specification of a greater proportion of the goal path,…

Mind-research "psychenauts" are exploring the last great frontier - the mystery of man's inner life. (Editor)

This publication shares current thinking, research, and practice in the area of higher order thinking skills with home economics educators, including teachers, supervisors, and teacher educators. The first three articles provide general discussions of thinking skills. They are "Introduction" (Ruth Pestle); "Can Higher Order Thinking…

Tasks based on the function concept (y = f(x)) were used in a study charting the development of anticipation in children from 5 through 7 years of age. In each task a desired outcome was a function of a combination of specific, rule-constrained, antecedent conditions. Subjects' behavior was scored according to criteria differentiating six levels…

The purpose of this study was to investigate the relationship between a student's stated preference for solving a problem and his/her actual problem solving methodology. Approximately 116 science students between the ages of 15 and 22 were given an 18 item abstract preference survey. Each student was interviewed and given the opportunity to solve…
