"Comprehensive Practical Activity" is an activity course in mathematics.It is characterized by the unique process of students’ independent inquiry with the problem(often the real problem scenario)as the carrier.Emphasize the comprehensive application ability of knowledge and innovative thinking ability.Comprehensive and practical training is extremely important for the cultivation of students’ mathematical ability in compulsory education stage.The formal definition of core accomplishment in Compulsory Education Mathematics Course Standard(2022 Edition)(hereinafter referred to as "New Course Standard")is a high-level summary of students’ mathematical ability.Therefore,it is very necessary to carry out teaching research on “Comprehensive Practical Activity” from the perspective of new course objectives.Based on the 2022 edition of Compulsory Education Mathematics Course Standard,this paper analyses the learning change of "Comprehensive Practical Activity" under the new course standard in 2002 and the educational value of "Comprehensive Practical Activity" under the core accomplishment of mathematics in junior middle school,and further carries out theoretical analysis and investigation on the teaching of "Comprehensive Practical Activity" under the core accomplishment,as well as the problems existing in the teaching of "Comprehensive Practical Activity".Case study is used to show the teaching strategy of "Comprehensive Practical Activity" under core accomplishment.The concrete research results are as follows:(1)By analyzing the new course standard and summarizing and studying the teaching literature of mathematics "Comprehensive Practical Activity",the development history of mathematics "Comprehensive Practical Activity" teaching and the development direction of "Comprehensive Practical Activity" under the new course standard are summarized.Through the change of each part of the new course standard,corresponding analysis is made on the teaching change of "Comprehensive Practical Activity".The objectives,contents,evaluation and educational value of the teaching design of "Comprehensive Practical Activity" of mathematics in junior middle school under the new course standard have been determined.(2)Explore the implementation process of "Comprehensive Practical Activity" teaching under the new curriculum standard,determine the overall teaching design process,and carry out the teaching process in stages,including the selection of teaching topics,the design of teaching contents and the planning of teaching tasks.The first is the selection of the real situation,and the second is the group cooperation to carry out exploratory experiments to complete knowledge learning and project production.In the summary and evaluation stage,it is divided into two parts: project achievement display and project evaluation communication,and the evaluation table of students’ multiple evaluation subjects is designed.(3)According to the established teaching implementation process of "Comprehensive Practical Activity",interviews with front-line teachers in the region are conducted before and after the process,and project-based teaching cases of "graphic similarity" are designed by learning experience,and teaching practice is carried out in the third grade of junior high school.By using the methods of student questionnaire and teacher interview to analyze the teaching effect,it is found that during the process of teaching,the interest of students in "Comprehensive Practical Activity" and mathematics has been aroused,the core accomplishment has been realized and the satisfaction and support for teaching has been shown as a whole.Teachers also expressed satisfaction with the teaching of "Comprehensive Practical Activity".Through a descriptive statistical analysis of the questionnaire,students’ attitudes towards this "Comprehensive Practical Activity" lesson were understood,and teacher-student attitudes were summarized.The research conclusion has certain reference value,which can be used for reference in classroom teaching of mathematics "Comprehensive Practical Activity" in junior middle school from the perspective of core accomplishment for mathematics teachers. |
