Research On Teaching Strategy Of Solid Geometry Module In Senior High School Under Core Literacy

Core accomplishment is the focus of mathematics education circle in recent years,which is the thinking method,thinking attitude and ability of applying mathematics to real life based on many mathematical knowledge and skills.Stereo geometry module is the closest to people' s daily life.As one of the important contents of high school mathematics,its educational value is to improve axiomatic thinking on the basis of learning plane geometry,and to train students'spatial imagination thinking,ability of applying mathematical language to transform communication and intuitive perception,ability of logical argumentation,and ability of analysis and operation.Therefore,from the perspective of cultivating core literacy,it is necessary to study the strategies of teaching and learning for stereo geometry module.In the process of teaching and learning,this paper tries to organically combine knowledge,skills,thinking mode,culture,mathematical thought and core literacy,to maximize the implementation of the new curriculum concept.To pay attention to the high school mathematics solid geometry module teaching in the concept and method of innovation,pay attention to the high school students learning method efficiency,hope to make a contribution to the core mathematical literacy concept into the high school mathematics teaching.In this paper,high school teachers and students as the research object,mainly using the literature method,questionnaire survey,interview survey method.The aim is to study the current situation of teaching and learning of solid geometry module from the perspective of mathematics core literacy,to find out the causes of the problems.The problems existing in the teaching of teachers are summarized as fol lows:failing to grasp the characteristics of the solid geometry module itself,insufficient ability to cultivate the core literacy awareness,low function of the integration of information technology and solid geometry module teaching,and less application of mathematics culture.Found that students learning:understanding and memory of solid geometry knowledge problems,perceiving defects in solid graphics,lack of logical reasoning and computing ability,thinking stereotype in junior and senior middle schools,and learning adaptability.Around the above problems,with specific examples to optimize the teacher's teaching strategy:the first is to use the vision of developing core literacy to process and integrate teaching materials,carefully select exercises,review questions,thinking questions and other exercises,and transform them into the teaching of three-dimensional geometry module to carry out students' thinking activities.The second is to give full play to the identity of the organizer,inspire the students' subjective initiative and sense of cooperation,and set up some practical activities of exploration and modeling to enhanc e the scientific spirit of the students;the three-dimensional geometry is changed from multiple angles,highlighting various mathematical thinking methods,and deepening the students'awareness of innovation.Third,relying on solid geometry to spread mathematical culture,creating a variety of teaching situations;realizing information technology to effectively help students establish the concept of space,improve the abi lity of image and logical thinking;optimizing teaching evaluation froma global perspective.It also puts forward the learning strategies of students,the first is to enhance the learning emotion,build the knowledge framework of solid geometry module,effectively improve the thinking mode,and effectively improve the ability of analysis and problem solving.The second is to change the learning methods of preview,listening and consol idation after class,improve the ability of mathematical thinking,understand and master the thinking and research methods of open inquiry.The third is to form a good habit of reading pictures and drawing pictures,establishing mathematical models,flexibly using space vector as an efficient tool,rigorously demonstrating three-dimensional geometry problems,self-reflecting and summarizing laws,standardizing training,and paying attention to the learning of process and thought.
