Research On The Teaching Strategy Of Cultivating High School Students' Logical Reasoning Literacy ——Take The Teaching Of Mathematical Propositions As An Example

In order to implement the fundamental task of Lide Tree and give play to the educational function of education,for mathematics disciplines,cultivating and improving the core literacy of mathematics is the primary task of educators.As one of the core qualities of high school mathematics,logical reasoning is an important guarantee for mathematical rigor,the basic thinking quality of mathematical communication,an important factor in rational thinking and intellectual development,and an irreplaceable role in promoting the innovation and development of mathematics.Therefore,it is of great significance to understand the current level of logical reasoning literacy of high school students for further developing logical reasoning literacy in mathematics education.This article mainly includes the following four parts:In the first part,by consulting a large number of literature to understand the research status and teaching background of logical reasoning literacy,the research problems,the purpose and significance of the research are determined.The second part defines the core concepts of this paper,including logical reasoning,logical reasoning literacy,mathematical propositions and mathematical proposition teaching,and selects certain educational teaching theories to provide scientific basis and lay a theoretical foundation for the subsequent proposal of teaching strategies and design teaching.In the third part,some high school students in the author's area were investigated and interviewed with teachers,the test data was collected and sorted out and statistically analyzed,and the following research conclusions were obtained in combination with the interview results of mathematics teachers: First,students' logical reasoning literacy has developed in all dimensions,but the development is uneven;second,students' reasonable reasoning and deductive reasoning ability have developed,but the development is unbalanced;third,teachers attach importance to the cultivation of logical reasoning literacy,but effective teaching strategies are insufficient.The fourth part,based on the above survey results,proposes five teaching strategies for cultivating students' logical reasoning literacy: first,the co-development of reasonable and deductive reasoning,and attach importance to the form of logical reasoning;second,to create rich situations to introduce propositions and stimulate interest in logical reasoning;third,to build a relevant propositional knowledge structure and lay the foundation for logical reasoning;fourth,to explore a variety of methods of propositional argumentation to improve logical reasoning ability;fifth,to provide mathematical language expression opportunities to show the reasoning thinking process.Finally,according to the learning theory and the proposed teaching strategy,the teaching designed with "The First n Items of the Equal Difference Series" as an example is designed to cultivate the logical reasoning literacy of high school students and explain it.
