数学命题课型教学模式为:提出猜想引入命题,证明命题提升思想, 命题应用反馈信息,小结升华．一、提出猜想引入命题数学命题(定理、公式)的引入首先向学生提供一系列的实例、研究素材,让学生在教师设计的情景下,通过观察、实验、操作、讨论和思考,探索规律,提出猜想和假设,然后引入数学命题．在设计时应注意以下具体问题: Mathematical proposition teaching model as follows: put forward the conjecture to introduce propositions, prove the proposition to enhance thinking, proposition application feedback information, summary sublimation. I. Introduction of Conjecture Introduction of propositional mathematical propositions (theorems, formulas) First of all, students should be provided with a series of examples to study materials so as to enable students to explore laws through observation, experiment, operation, discussion and reflection under the circumstances of teachers’ design. Propose conjectures and assumptions, and then introduce mathematical propositions. The design should pay attention to the following specific issues:
