Research On Cultivating High School Students' Logical Reasoning Literacy

The core literacy of mathematics is the concentrated expression of the objectives of the mathematics curriculum,logical reasoning is one of the six core literacy of mathematics specified in the "Standards of Mathematics Curriculum for General Senior High Schools(2017 Edition)".It is an important method to explore and discover conjectures and cultivate,students' logical reasoning literacy is an important goal of mathematics teaching.As a key component of high school mathematics,the sequence is widely used in logical reasoning,which is a good material for cultivating students' core literacy.Based on relevant theories of pedagogy,this thesis summarizes the research results of logical reasoning at home and abroad,and proposes the level division of logical reasoning literacy of high school students in sequence learning by taking sequence knowledge of high school students as the carrier.The current situation of logical reasoning literacy of high school students is studied by adopting the method of questionnaire survey and outline interview.In terms of students,high school students to study in the sequence of mathematical logic accomplishment present situation is not optimistic,most of present high school students logic accomplishment between level 1and 2,only a few students can meet the requirement of level 3.In terms of teachers,high school teachers in the teaching focusing too much on fixed the problem solving process and the standard answer,make the logic reasoning quality and innovation ability of students comprehensive training.Most of the teachers value recognition logic accomplishment,but lack of teaching strategies lead to teachers superficial to the attention of the logic reasoning.In order to solve the above problems,this dissertation puts forward the teaching strategy of effectively cultivating students' logical reasoning from the perspective of teacher teaching:(1)introduce appropriate classroom situations and pay attention to the process of knowledge generation;(2)fully link with the reality of life and motivate students to make bold guesses;(3)be good at mining teaching materials and makeappropriate use of teaching aids;(4)design diverse mathematical activities to guide students;(5)adapt the psychological state of students,follow the principle of teaching students according to their aptitude;(6)change their own educational concepts and enhance the educational theory.This is the innovation point of this research.In-depth analysis of the sequence in the textbook of the 5th edition of the high school mathematics content,to implement the core of mathematics to the classroom as the goal,design classroom teaching cases,analyze the sequence of classic exercises,expect to provide further reference to the further implementation of the curriculum standards and teachers to the students' logical reasoning.Finally,summarizing the dissertation with knowledge innovative points such as pertinence and application value in teaching practice,and explain the lack of research and prospects.
