Study On Micro Topic Design For Cultivating Mathematical Operation Literacy

The core elements of basic mathematical thought can be summarized as abstraction,reasoning and model,mathematical abstraction and intuitive imagination correspond to abstraction,logical reasoning and mathematical operation reflect reasoning,mathematical modeling and data analysis reflect model,so these six are determined as the key competencies of mathematics.Among them,mathematical operation is regarded as one of the the key competencies of mathematics,which shows its important status.Therefore,how to cultivate mathematical operation literacy naturally becomes an important issue.In face of the current situation that students' operational ability is declining day by day,this paper proposes and studies the method of cultivating mathematical operation literacy with micro topic.Taking the content of "conic curve" in senior high school as an example,this paper puts forward the selection and organization of micro-topic teaching content to cultivate mathematical operation literacy,and applies the designed cases to teaching practice to test whether students' operation ability has been improved.The research methods used in this study include literature research,classroom observation,interview,homework correction and case study.Firstly,through the literature,to understand the key competencies,mathematical competencies,research status of micro topic,to clear research direction and concrete problems of my study.Secondly,combing good teaching concept and teaching methods in literature,combining with the teachers and students are faced with the operation status and problems of deep experienced teachers teaching classroom,interview currently engaged in the related research experts and scholars,thus put forward how to cultivate the competencies of mathematics by project design.Lastly,I will apply the design of micro project case to the teaching practice,to test whether this monitoring project to cultivate mathematics accomplishment does exist.There are two main conclusions in this study.The first is when selecting the content of micro-topic teaching to cultivate mathematical operation literacy,problems reflecting knowledge points should be acceptable;Having various train of thought and methods to solve problems;Relating to mathematical methods of thought;can be generalized.Problems are derived from textbooks,students' practical computing problems,and exam questions.The another is when organizing and cultivating the content of micro-topic teaching of mathematical operation literacy,it can be carried out according to the problem group training and variant training.In the problem group training,the solution strategy of inductive operation problem and the solution method of variant linkage operation problem are summarized.In a word,the cultivation of mathematical operation literacy through micro-topic teaching is not achieved overnight.In order to achieve real effects,teachers need to continuously study on content selection,organization and development in combination with teaching practice.
