The Teaching Design Of The Number-shape Combination Unit Explores

Current high school mathematics teaching more exam-oriented education,ignore the integrity of subject knowledge,to break through the current teaching dilemma,many education scholars began to pay attention to more optimized teaching mode,the students ’core accomplishment and mathematical thinking method as the focus of high school mathematics teaching,and unit teaching is the key to cultivate students’ core literacy and mathematical thinking method,unit teaching around mathematics integration curriculum content,value the mathematical thinking method penetration in the teaching process,to exercise students ’logical thinking ability,develop the students’ core literacy.The research objectives are as follows:①Provide unit teaching theoretical reference of mathematical thinking and methods;② explore the design and construction process of unit teaching of"combination of numbers and forms";③ study the practical value of unit teaching of "combination of numbers and forms".Taking part of the content of the compulsory function as an example,the function content runs through the whole high school mathematics content,which plays an important role in high school teaching.The study used literature research,questionnaire survey,comparative analysis and case analysis.Summarize and consider the theoretical basis,model basis and construction process of unit teaching.Unit teaching uses "ADDIE" model to carry out unit teaching design,and the basic ideas and steps of teaching design include preliminary preparation,development design,evaluation and modification.In the early preparation,the type of unit teaching is determined,the unit teaching framework is constructed,and the teaching elements are analyzed.During the development and design,the unit teaching objectives are compiled,the unit teaching is arranged by class hours,the unit teaching content of "combining numbers and shapes" is designed,and the continuous evaluation method is selected to evaluate students’ learning ability and application ability.Teaching suggestions are drawn from the teaching case study:① Unit teaching should pay attention to the integrity of teaching content;② "combination of numbers and shapes" plays a key role in the process of function abstraction;③ unit teaching process should be student-oriented design.Conclusion from the survey and practice results:① high school teachers have a poor understanding of unit teaching;② high school students have a simple understanding of "number form";③"number form" unit teaching is an important means to cultivate students’ combination of mathematics and mathematical literacy.
