教无定法,法因势异.在适当的教学阶段酌情运用推理网络求解法对培养分析解决问题能力或许有益. 该法实质是启发学生将零星片断的化学信息,通过化学理论分析、逻辑推理画出框图网络逐步逼近问题的答案.其特点是条理清晰、直观严谨、推之有据、言之有理.该法可因学生水平让其独立完成或师生讨论共同完成. 例1.某蛋白质水解得一溶于水的固体化合物A,A在电场中因pH的不同分别移向阴、 Teach indefinite method, the law due to potential differences in the appropriate teaching stages, as appropriate, using reasoning network to solve the problem of training capacity to analyze and solve problems may be beneficial.The law is to inspire students to splinter pieces of the chemical information through chemical theory, logical reasoning Out of the box diagram network gradually approach the answer to the question, which is characterized by a clear, intuitive rigorous, well-founded, well-reasoned.The law can be completed independently by the student’s level or teachers and students to discuss together.Example 1. A protein hydrolysis Got a solid compound dissolved in water A, A in the electric field due to the different pH were shifted to the negative,
