A Case Study Of Mathematics Logical Reasoning Accomplishment For High School Students,Based On The"Three Teachings"Concept

His article is based on the "three teachings" concept of high school students' logical reasoning literacy training course study.First,logical reasoning literacy is divided into plausible reasoning and deductive reasoning,and the corresponding level division is formulated.According to the level division,a set of test questions is prepared for prediction and actual measurement.The interview outline is compiled in accordance with the current status of students' logical reasoning literacy.A math teacher analyzes the main factors that affect the logical reasoning literacy of high school students,and finally combines the current status of high school students 'logical reasoning literacy with the main factors that affect the development of students' logical reasoning literacy.The test results show that the logical reasoning literacy of high school students is at level 3,among which the reasonable reasoning and deductive reasoning are also at level 3 respectively;the high school students' reasonable reasoning,deductive reasoning and logical reasoning literacy are all slightly higher than that of boys.However,there is no significant gender difference;there is a significant difference between the students 'logical reasoning literacy at level 1 and level 2,level 1 and level 3;there is no significant difference between the level 2 and level 3 students' logical reasoning quality.The results of the questionnaire survey indicate that most students can recognize their deficiencies in logical reasoning,and believe that learning logical reasoning knowledge is helpful to improve mathematics results;although teachers often encourage students to use logical reasoning methods to study problems,students are sympathetic.There is not enough knowledge about reasoning and deductive reasoning.Five mathematics teachers were interviewed from two aspects: the understanding of logical reasoning literacy and the cultivation of logical reasoning literacy of high school students.The two selected teaching contents were studied in terms of relevant analysis,instructional design,classroom record,instructional reflection and research summary.Lesson study reveals that the concept of "three teachings" is helpful for the cultivation of logical reasoning literacy of high school students.The specific performance is as follows: "Teaching Thinking" helps students form problem awareness;"Teaching Experience" helps students experience the occurrence and development of knowledge,and comprehends mathematical thinking methods;"Teaching expression" enhances the knowledge of mathematics.
