An Investigation On Probability Of Learning Disabilities Of Senior Three Students

As one of the four main lines of high school mathematics curriculum,probability is closely related to the other three main lines.It is an important part of high school mathematics teaching content,and it is also one of the required mathematics examinations for college entrance examination.On the basis of long-term learning of deterministic knowledge,it is difficult for students to adapt to the probability content of uncertainty,and it is easy to form learning obstacles.In order for students to better learn the knowledge of the probability module and develop the core literacy of mathematics,it is particularly important to investigate the probability learning disabilities of high school students,analyze the reasons for the obstacles and explore the strategies to solve the obstacles.This article mainly uses three research methods to investigate and study 270 senior science students in a senior middle school in Dali Prefecture,Yunnan Province,use questionnaires and test papers to investigate students' probabilistic learning,and use SOLO classification evaluation theory to test students The results of the volume are divided into answer levels.Combined with the survey results,it is found that students have obstacles in emotion,memory,thinking,operation,representation,discrimination,understanding,and application of probabilistic knowledge in the process of probability learning.On this basis,we analyzed and found that the main reasons for the obstacles are:(1)Students' recognition of learning mathematics and low emphasis on probability.(2)Poor study habits.(3)Fewer representation experience opportunities,lack of awareness and skills for generalization,less reserve of basic knowledge of probability,and lack of in-depth learning.(4)Weak dialectical and logical thinking ability.(5)The understanding of knowledge is mechanically rigid.(6)Lack of common sense of life and society,poor mathematics reading habits and mathematics reading ability.Based on the above results,we propose the following six teaching strategies:(1)Improve learning interest and learning initiative;create a good learning atmosphere.(2)Multi-representation probability knowledge,using a variety of teaching methods and means.(3)Review and sort out the teaching,focusing on the formation and deduction process of knowledge.(4)Carry out thematic teaching,focusing on one problem with multiple solutions and changes.(5)Summarize and demonstrate the ideas and methods of problem-solving,and show wrong examples.(6)Strengthen the awareness of probability application and cultivate students' mathematics reading habits and reading ability.In addition,we recommend that students develop good study habits and learn to write math diaries during the learning process.
