Abstract:To explore the impact of Prior declarative knowledge and abductive reasoning in the generation of hypotheses, this paper investigated 49 sixth grader’s Prior declarative knowledge and generation of hypotheses on pendulum motion. The results showed, a number of subjects who have prior declarative knowledge about the pendulum motion failed to apply their prior knowledge 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 declarative knowledge.To cultivate students’ science hypotheses ability, teachers need to help students’abductive reasoning skills develop gradually.
