Research On The Teaching Design Of The Unit Of Combination Of Number And Shape

Since the promulgation of the "General High School Mathematics Curriculum Standards(2017 Edition)" in 2018,it means that my country’s high school mathematics teaching will enter a new stage of reform and development.The new curriculum standard emphasizes the need to optimize the curriculum structure,with unit(topic)teaching as the guidance,to provide a common foundation and diversified choices for students’ development;highlight the main line of mathematics teaching,highlight the internal logic and thinking methods of mathematics,and pay attention to the penetration of mathematics ideas,At the same time exercise students’ ability to apply mathematical knowledge to solve practical problems.Unit teaching is no longer a fresh vocabulary.The promulgation of the new curriculum standard has enabled researchers in the education circle to focus on unit teaching again to help the cultivation of mathematical thinking and the implementation of core mathematics literacy.Therefore,this article aims to cultivate students’ thinking of combining numbers and shapes through unit teaching.For this reason,this article has designed two research questions:(1)How to systematically carry out the unit design of "combination of number and shape" ?(2)How effective is the teaching implementation of the "combination of number and shape" unit?The research uses the content of a conic section as the carrier of the new teaching material version B,researches the teaching plan design of the unit teaching of "combination of number and shape",and uses the questionnaire method and experimental method to conduct research.Refer to Professor Lu Shihu’s unit teaching design steps for unit teaching design.First,analyze the six elements of unit teaching,then formulate unit teaching goals,then design the teaching process,and finally implement the teaching.Through the data of the pre-test paper and the post-test paper,it is found that after the two classes of the same level in the pre-test,the experimental class and the control class have significant differences in their ability to solve problems using the combination of figure and figure after the teaching of the combination of figure and figure.Unit teaching is helpful to the cultivation of the combination of number and shape.Three conclusions can be drawn from the above research: First,the unit teaching design is an important means of cultivating the idea of combining number and shape;second,the use of modern information technology media in the unit teaching of combination of number and shape can help improve classroom efficiency;third,high school First-line teachers have deviations in the understanding of unit instructional design.Therefore,the research puts forward three suggestions: First,when designing the unit of combining figures and shapes,pay attention to the changes in new textbooks and the requirements of the new curriculum;second,when designing the units of combination of figures and shapes,we should pay attention to academic conditions and optimize teaching.Design;Third,when designing the teaching design of the combination of number and shape,we should use more multimedia equipment to experience the idea of combination of number and shape through the change of graphics to increase the joy of learning.
