The premise of scientific inquiry consciousness training is to have strong conjecture and hypothesis ability. To foster students’ hypotheses and guesswork, students should be able to retrieve the relevant information of the question in the brain and face up to the problem to be solved in their learning, and make use of their own knowledge and experience to carry out this problem Analyze, summarize, and then guess the factors that cause the problem.
