Teaching Research And Case Analysis Of Mathematical Proposition In Middle School

Mathematical proposition is an important part of mathematics knowledge,and the position in the whole mathematical knowledge system is not replaceable by other knowledge.Actively carry out mathematical proposition teaching is helpful for students to solve mathematical problems and mathematical knowledge learning,to improve students' logic thinking ability and language expression ability,but also conducive to the development of mathematics itself.Therefore,the study of mathematical proposition teaching strategies not only has theoretical significance for improving the teaching level of middle school mathematics teachers,but also has important practical significance,and has increasingly become a focus of attention.The paper is divided into six parts:The first part introduces the research background,research significance,domestic and foreign research status,research tasks and methods,and thesis structure.The second part defines the related concepts of mathematical propositions,gives the basic content of the teaching of middle school mathematics propositions,and introduces the learning methods of middle school mathematics propositions.The third part expounds the relevant theoretical basis for carrying out the research.The fourth part,under the guidance of related theories,aims at several basic links of mathematics proposition teaching: introduction of propositions,proof of propositions,application of propositions,construction of propositional systems,and put forward specific mathematical proposition teaching strategies respectively,and aiming at each teaching strategy,and each instructional strategy is concretely explained with examples.The fifth part,combining mathematics teaching theory,teaching strategy based on mathematics proposition,designing for the two topics of "the basic inequality" and "the Pythagorean theorem" with details,and adopting analysis and explanation of how to use mathematical proposition teaching in mathematics proposition teaching.The sixth part is the conclusion and prospect.It mainly summarizes the thesis research and puts forward the problems that need to be improved in the study of mathematicalpropositions.
