Analysis: Judd once did a famous underwater shooting experiment. He divided 1 1 year-old primary school students into two groups, A and B, and practiced shooting in water. The subjects in group A were taught the principle of refraction of light in water before practice, while the subjects in group B only practiced and tried, but were not taught the principle. This result shows that when learning shooting, because the second and third groups of subjects understand the principle, their scores are better than those of the first group of subjects who practice mechanically; The results of the third group are better than those of the second group, which shows that the learning of problem solving and its application in new situations will be better when we understand the relationship between the principle and its practical application situation. They not only further confirmed Judd's theory, but also pointed out that generalization is not an automatic process, which requires the transfer of intellectual skills's general rules and is closely related to teaching methods. If we pay attention to how to generalize and think in teaching methods, we will increase the possibility of positive transfer.
The basic viewpoint of this theory: Judd's experience categorization theory emphasizes the role of generalized experience or principle in transfer. According to this theory, the previous learning can be transferred to the next learning because the general principle has been obtained in the previous learning, and this general principle can be partially or completely applied to the previous learning and also applied to the next learning. According to Judd's experience classification theory, the key to transfer is: the common principles or summarized experiences shared by the learners and the two activities.
