An Investigation into the Effects of Generating Hunches Upon Subsequent Search Activities in Problem Solving Situations.
Wilson, John T.
Effects of generating hunches upon subsequent search activities in problem solving situations were studied among 45 students, 9-11 years of age. The population, divided into three groups, was assigned to observe a contradictory stimulus. The first group was asked to write hunches, while the second was allowed to read a set of hunches. Hunch activities were not carried out among the control group. All subjects were required to classify a set of procedures as "useful" or "not-useful," relative to the contradictory event. Each student was given the materials and procedures described as useful in his own classification. A posttest was given to measure the quality of the solution formulated. The overall time for completing search activities was recorded. Analyses of findings showed the presence of direct influences of generating hunches on search behavior and quality of solutions. The first group classified significantly fewer procedures as useful, spent significantly more time in search, and demonstrated a significantly higher quality. No significant differences were found between the control and the second experimental groups. Implications of the present research for curriculum design and teacher training were recommended. (CC)
