| The education informatization 2.0 action plan issued by the ministry of education in 2018 emphasizes the in-depth integration of information technology and subject teaching to improve the application level of information and the information literacy of teachers and students.The mathematics curriculum standards of ordinary high schools(2017 edition)points out that "teachers should pay attention to the deep integration of information technology and mathematics curriculum to achieve the results that are difficult to achieve by traditional teaching methods".Therefore,the integration of information technology into mathematics teaching is becoming an important topic in mathematics education.Solid geometry is the main carrier of cultivating high school students' core qualities such as intuitive imagination,mathematical abstraction and logical reasoning.How to solve the difficulties in three-dimensional geometry teaching effectively,improve the effectiveness of three-dimensional geometry teaching,and promote the development of core qualities has been a topic of mathematics education research.Hawgent dynamic math software is currently the most powerful math education platform in China,with mathematical operation object,mathematical object dynamic,mathematical thinking visualization and other functions.However,in the real teaching,how to use the function of the software to effectively teach mathematics and other problems are expected to be solved.Based on the above thinking,this study is based on the concept of mathematical multi-representation learning,taking the three-dimensional geometry teaching as an example,to discuss the teaching thinking of using the software to assist the three-dimensional geometry teaching.This research mainly includes theoretical research and practical research.In terms of theory,firstly,by studying the literature,the author sorts out the definition of several core concepts such as integrator and mathematical multi-representation learning concept.Secondly,the paper summarizes the research of the dynamic mathematical software and the basic features and functions of the dynamic mathematical software.Then,the content structure and research status of solid geometry are expounded.Finally,through theoretical research and practical exploration,this paper summarizes three strategies of applying hao jun's design of solid geometric integrals: multivariate representational relation strategy,time-space proximity strategy,and representational variable consistency strategy.In practice,it mainly focuses on experimental research,supplemented by case study.Through qualitative and quantitative analysis of questionnaire survey,individual interviews and before and after test papers,this paper discusses the effect of using hao jun integrator to assist three-dimensional geometry teaching on the three levels of students' intuitive imagination literacy and the variables of mathematical learning process.The research shows that the application of hao jun integrated parts in the three-dimensional geometry teaching can significantly improve the academic performance of students in the experimental class.To improve the level one and level two of intuitive imagination literacy,but has little influence on level three;Can positively influence the student learning process. |
