Strategic Research On The Design Of Mathematical Theorem Micro-Course In Junior High School

The《Mathematics curriculum standard for compulsory education(2011 Edition)》pointed out "modern information technology is not only an important tool for teachers to teach but also a powerful weapon to promote students’ independent learning.Making good use of modern information technology can effectively improve the way of teaching and learning".As a new type of educational resource,micro-course has made some achievements in the actual mathematics classroom.With small capacity and fine content,it is beneficial to improve students’ learning effect of mathematics and effectively improve teaching and learning.Mathematical theorems are an important carrier for students to develop mathematical thinking,form mathematical skills,and master mathematical knowledge.It is also an important teaching content for students to discover,put forward problems,analyze,and solve problems.As a result,this article is based on the Freidenthal mathematics education theory and put forward mathematical theorem micro-course design strategies in the junior middle school.Design the specific case of junior middle school mathematical theorem micro-course,takes student’s mathematical reality,emphasizes the students conjecture verification,and lets the student experience from discovery and math questions to analyze and solve mathematical problems.This research mainly discusses in detail from the aspects of theoretical research and practical research.In terms of theory,first of all,many domestic and foreign references were consulted to sort out the definition of micro-course at home and abroad and the related research trends of micro-course.Secondly,consult a large number of theorems teaching-related literature,sort out the theorems teaching research status;Then,put forward the junior middle school mathematical theorem micro-course design-related strategy: link the old knowledge review,reduce the cognitive load;Create a question to guide thinking,stimulate learning motivation;Encourage process participation and enhance reasoning ability;Guiding inductive generalization,cultivating logical thinking;Enrich summary reflection,improve the knowledge system.Finally,taking the teaching content of《Determination of congruent triangles》in the first volume of mathematics of Grade 8 published by Hunan Education Press as an example,the corresponding micro-course is designed.In the aspect of practice,first of all,based on micro-course design completed,The teaching research of junior middle school mathematical theorems micro-course based on the micro-course design strategy of Freidenthal’s mathematics education theory was carried out in the practice school.First,the control class adopts the ordinary version of the micro-course for teaching,and the experimental class adopts the strategy design version of the micro-course for teaching.Then,after the end of the actual teaching experiment,the test questions and questionnaires related to the teaching content were distributed.The students were selected from the two classes for case interviews to analyze the math learning situation of the two classes after the experiment and the changes in the students’ emotional attitudes and other aspects.The research results show that the application of design strategy of junior middle school mathematical theorems series micro-course helps improve students found in reality and put forward the mathematics problem,analysis and the ability to solve mathematical problems,help to improve their academic performance and improve their learning styles,emotional attitude towards students and so on all have a significant positive role.
