A Practical Study On Teaching Of Math Exercise Class With Micro-lesson In High School

With the rapid development of information technology,digital education resources have been continuously developed in recent years,bringing about changes in education.The rise of micro-lessons has brought about changes in students? learning methods and teachers? teaching methods.Exercise class is an important part of students' consolidation of mathematics learning,and it is also an important part of mathematics classroom teaching.These following problems are worth thinking about.How to use Micro-lesson to improve the problem of teaching heavy in math exercise class in senior high school?Can Micro-lessons solve the problem that some students have difficulty absorbing content and can't keep up with teachers' teaching ideas in traditional class ?Firstly,this paper explains the background,purpose and significance of the research by consulting relevant document s and materials and introduces the research content and method.Secondly,this article sorts out the definition of Micro-lessons and exercise classes,and study the relationship between them.Thirdly,this article conducts a survey on the current teaching situation of math exercise lesson.And this paper constructs a teaching mode of assisting high school mathematics learning problems with micro-lessons,basing on the analysis of the problems and the characteristics of micro-lectures.At the same time,based on three theoretical foundations,this paper proposes design strategies for exercise-type Micro-lectures,and gives three examples to enrich the practical case of application.Finally,three types of exercise-type Micro-lectures are applied to the teaching of mathematics in high school to verify the effectiveness of micro-lectures.This paper uses the unequal group experiment method to design the experimental group and the control group.The experimental group exerted the influence of micro-class assistance,while the control group did not exert influence,and the irrelevant variables are controlled.After the teaching experiments,there is a test and questionnaire surveys for students.In the end,the paper analyzes the data of the two groups of experimental tests,and the questionnaire survey of the students after the experiment.There is a significant difference in the post-experimental mean of the experimental group and the control group,and the experimental group is better than the control group.The results of the questionnaire show that most students are willing to use micro-lectures to explain the exercises and their enthusiasm for learning mathematics has increased.Finally,the article summarizes the drawbacks of study and look forward to the future?s improvement.
