Research On Conic Section Micro-theme Teaching Based On Mathematical Operation Literacy

Mathematical operation is not only the basic behavior of solving mathematical problems,but also applied to the whole process of mathematical development,and is the key content of mathematics teaching.As one of the six core qualities proposed in the new mathematics curriculum reform,mathematical operation literacy plays a crucial role in the overall development of students’ mathematical literacy.But now,the actual teaching reflected in the actual mathematical operation literacy of students and the new curriculum standards are far from the requirements,high school mathematics teachers on the cultivation of students mathematical operation literacy in a relatively neglected and without thinking state.In the face of the current situation,this paper takes the conic curve related knowledge of senior high school as an example,and cultivates students’ mathematical operation accomplishment through a teaching method called"micro-thematic teaching".The aim is to put forward some new ideas for the teaching of cultivating mathematical operation accomplishment.This paper mainly studies the following three aspects through literature research,questionnaire survey,interview survey and classroom observation method:First of all,through literature review,the literature related to mathematical operation is sorted out to understand the current research status on the cultivation of mathematical operation literacy.At the same time,the literature related to micro-topics is classified to understand the characteristics,design strategies and application effects of micro-topics.Secondly,questionnaires and test papers were carried out to understand the problems existing in the current conic curve learning,and the teaching status of micro topics and mathematical operation literacy was understood through interviews with teachers.Finally,four principles of micro-thematic design are put forward:micro-flexible principle;The student-centered principle;Practical and effective principle;Principle of diversity of means;And four strategies for cultivating operational literacy through micro-topics:focusing on basic knowledge;Infiltration thinking method;Using variant training;Focus on summary and reflection;Based on design principles and teaching strategies,relevant teaching models are put forward,and three conical micro-special teaching cases are designed accordingly.
