An Investigation On Logical Reasoning Literacy In Solid Geometry Of Senior Three Students In K City

Logical reasoning,one of the six core qualities of mathematics,is an important way for students to find and solve problems,and an essential ability for students to learn and live.It enables students to have logical and orderly communication and discussion.Logical reasoning literacy plays an important role in the development of students.In order to better develop the logical reasoning literacy of senior high school students,it is particularly important to investigate the current situation of the level of logical reasoning literacy of senior high school students,analyze the reasons that affect the development of students' logical reasoning literacy and explore the training strategies.In this study,226 senior high school students in K city were investigated on their level of logical reasoning literacy by using the test paper.Then,the reasons influencing the development of students' logical reasoning literacy were analyzed by using the questionnaire and interview.Finally,based on the status quo and influencing factors of students' logical reasoning literacy,the training strategies and teaching cases were put forward.The main conclusions of this study are as follows:As a whole,about 64% of the students in senior three have met the requirements of level 1,34% of the students have met the requirements of level 2,and 25% of the students have met the requirements of level 3.Under the school dimension,there are significant differences in the level of students' logical reasoning literacy at different levels High school students have good foundation,strong teachers and high level of students' logical reasoning literacy;in the discipline dimension,there are significant differences in the level of students' logical reasoning literacy,science students are more active in thinking and strict in all aspects,and the level of logical reasoning literacy is higher than that of Arts students;in the gender dimension,there is no logical reasoning literacy level of boys and girls Significant difference.The main reasons that affect the development of students' logical reasoning literacy are as follows:(1)positive factors: Students' mathematical emotional attitude and values;the use of multi-disciplinary logical reasoning methods;willing to explore and actively strengthen the use of mathematical language;good learning habits,rigorous reasoning habits;teachers' teaching methods.(2)negative factors: students lack the basic knowledge and methods of logical reasoning literacy;they will not summarize and reflect,and sort out knowledge;students have confused thinking and careless reading.Based on the above research results,the following training strategies are put forward: ? pay attention to concept teaching and firm foundation of logical reasoning.(2)set up the problem situation skillfully and create the starting point of logical reasoning.(3)encourage reasonable reasoning and infiltrate logical reasoning rules.(4)verification of deductive reasoning and demonstration of logical reasoning process.(5)build a knowledge system and sort out the logical relationship.It is hoped that this research can arouse the attention of teachers on the cultivation of logical reasoning literacy in high school students' solid geometry,and provide reference for the effective implementation of mathematical core literacy in teaching.
