Research On The Teaching Of Solid Geometry Based On The Core Literacy Of Logical Reasoning

Solid geometry mainly focuses on the relationship among the shape,size and position of objects in the real world,which is a tool to understand,describe and associate with the real space.It can fully reflect the relationship between man and the objective world,mathematics and the objective world.Solid geometry can not only be conductive to cultivating students 'good thinking habits,logical reasoning abilities and language expression abilities,but forming a scientific world outlook and reason spirit.To adapt to the requirements of the new era,it is very necessary to focus on solid geometry teaching based on the core literacy of logical reasoning.The paper mainly includes five parts.The first part introduces the research background,significance,domestic and international research status and research ideas.The second part adopts the literature analysis method to analyze the related mathematics educational theories of solid geometry teaching based on the core literacy of logical reasoning.Through the questionnaire and interview methods,the third part conducts the survey on the mathematics teachers and students of the high school in Yueyang and Xiangtan,in order to better understand the current status of solid geometry teaching based on the core literacy of logical reasoning.Based on the related investigation results,the fourth part analyzes the reasons and reasons,as well as further puts forward strategies for teachers training and teaching implementation.The fifth part also proposes two practical teaching designs based on the teacher training and teaching implementation strategies.Based on the above research,the following conclusions can be obtained:(1)The development of the core literacy of students' logical reasoning in the solid geometry teaching is very important,but the specific implementation is not optimistic in the actual solid geometry classroom teaching process.(2)The solid geometry teaching based on the core literacy of logical reasoning has put forward higher requirements for professional qualities of teachers.On the one hand,regarding the teacher training,it is very necessary to conduct the different training in their professional growth,strengthen the teaching communication between teachers,and better guide them to pay attention to students' core Literacy,in order to fully clarify the logical reasoning in the solid geometry.On the other hand,regarding the teaching implementation,it is necessary to choose the reasonable teaching model,pay attention to the integrity of teaching design,strengthen the training of geometric language,focus on the development of mathematical thinking and further improve the comprehensive level of the classroom teaching.
