Optimization Strategy And Applied Research Of Junior High School Mathematics Culture Micro Lessons

The "Internet + Mathematics Education" has become a hot topic in mathematics education at home and abroad,and the "Mathematics Curriculum Standards for Compulsory Education（2021 Edition）" in China particularly emphasizes that according to the content and ways of learning mathematics,the impact of information technology should be fully considered,Rich learning resources should be developed and provided to students.Modern information technology should be used as a powerful tool for students to solve problems and effectively improve the way of teaching and learning.Mathematics micro-lessons are a product that there is information technology deeply integrated into mathematics teaching and learning,and which his characterized by breaking the constraints of time and space in mathematics teaching and learning as well as changing traditional teaching methods.However,the quality of mathematics micro-lessons varies,so how to design and optimize mathematics micro-lessons has become an urgent research problem."The science of mathematics is one of the significant areas in the junior secondary mathematics curriculum.The science of mathematics is one of the cultures of humanity,whose language and content,methods,and ideas are essential components of modern civilization.Therefore,reflecting the value of culture,mathematical knowledge,teaching humanities,and the cultivation of humanism should be naturally integrated into a systematic whole by mathematics education.In this paper,they are the first section of Chapter 1 of the New Ideas Mathematics Reader（first year）as a case study,not only to optimize micro-lessons design on rational,mathematical culture and algebraic mathematical culture,but also to explore and discuss the impact of the optimization strategies on the micro-lessons effectiveness.In the next section,there are discussions from the view of theoretical and practical.In the first step,we search for the definition of micro-lessons and summarize them through a literature review.There are some strategies referred.perspective should be focused to realize cultural values,and two bridge should be built to bring into play the advantages of moral education.Four types of approaches are used to integrating mathematical ideas.Five principles are followed to select effective content.In the practical study,the HPM theory-based on optimization micro-lessons were shown to junior secondary school students.The data collected were analyzed using SPSS23.0 software to find the differences between the optimized and original micro-lessons.The results showed that secondary school students and primary mathematics teachers generally had positive attitudes towards the optimized micro-lessons in the cultural sector of junior secondary school mathematics based on HPM and other theories.Finally,After learning the optimized micro-lessons,junior secondary school students of understanding knowledge and learning styles were changed,interest were improved in learning and other aspects,and educational outcomes were significantly enhanced.
