摘要:The problem solving actvities developed for this formal asessment program are based on familiar, real life problems. Responses of third and fourth grade subjects to problem solving items were assed by problem solving ability,reasoning,and imagintin/creativity. Reliability of problem solving atvities was supported by the results of itererater reliability and Cronbach's alpha. Correlations between problem solving activities and the Nglieni Nonverbal Ability Test(NNAT: 1985) showed that cluster scores on the NNAT were significanty related to each score on the problem solving activities. Problem solving by gender showed that girls were more likely to express ideas than boys. There were also difences related to grade level on some items.
