| Abstract: | The purpose of the present study was to test the hypothesis that student’s abductive reasoning skills play an important role
in the generation of hypotheses on pendulum motion tasks. To test the hypothesis, a hypothesis-generating test on pendulum
motion, and a prior-belief test about pendulum motion were developed and administered to a sample of 5th grade children. A
significant number of subjects who have prior belief about the length to alter pendulum motion failed to apply their prior
belief to generate a hypothesis on a swing task. These results suggest that students’ failure in hypothesis generation was
related to abductive reasoning ability, rather than simple lack of prior belief. This study, then, supports the notion that
abductive reasoning ability beyond prior belief plays an important role in the process of hypothesis generation. This study
suggests that science education should provide teaching about abductive reasoning as well as scientific declarative knowledge
for developing children’s hypothesis-generation skills. |
