Research On The Construction Of The Evaluation Index System For The Design Of Teaching Objectives In The New Teaching Of Mathematics In Junior High School

Class teaching objective is the starting point and end-result of teaching activities and the basis of teaching activities and evaluation of teaching effects.The junior high school period is an important stage for the development of students' mathematical logic thinking and mathematical literacy.The new teaching type is the most common type of mathematics curriculum.The scientific and reasonable evaluation index system of teaching objective of junior middle school mathematics new teaching is not only able to evaluate the level of teaching objective design,but also can guide teachers to design teaching objective.The core issues of the research are:(1)What is the scientific and objective evaluation index system of the teaching objective design level of junior middle school mathematics new teaching?How to compile the index system?(2)What is the evaluation model based on the compiled evaluation index system?How to build evaluation model?Based on the two basic problems of the study,the evaluation index framework was initially formed by collecting,sorting and analyzing a large number of existing relevant literatuers.Secondly,NVIVO11 qualitative analysis software was used to code and analyze 73 teaching target samples of outstanding junior middle school mathematics new teaching,and the evaluation index system was initially formed.In order to improve the scientificity of the index system,the method of expert consultation is adopted to improve the preliminary evaluation index system based on expert suggestions.Then the experts were consulted again,and the evaluation model was obtained by calculating the weight of the indicators.Finally,the validity and reliability of the evaluation index system were verified through the raters' reliability and content validity test,so as to complete the construction of the evaluation index system for the design of the teaching objectives of the new teaching of junior middle school mathematics.The research conclusions are as follows:(1)The Evaluation Index System of Teaching Objectives Design for New Teaching of Middle School Mathematics has three first-level indicators,including curriculum standard requirements,teaching analysis,inspection and evaluation;9 secondary indicators,including course content,mathematical literacy,emotional attitude;Study situation analysis,textbook analysis,content application;9 sub-dimensions of hierarchy,operability and detectability,and evaluation standards corresponding to the 9 second-level indicators were formulated.The reliability and validity of the evaluation index system are good,which can effectively guide and evaluate the design of teaching objectives.(2)The evaluation model for the design of teaching objectives of new teaching of junior middle school mathematics obtained from the research:S=0.172T₁+0.169T₂+0.122T₃+0.157T₄+0.127T₅+0.081T₆+0.055T₇+0.101T₈+0.078T₉(where S represents the total score,and to represents the scores of each of the 9 second-level indicators respectively)Suggestions on the design of teaching objectives for the new teaching of junior middle school mathematics:teaching objectives clearly state the specific requirements that students need to achieve;Reflect the training requirements of mathematical thought and method,develop mathematical accomplishment;Reflect the cultivation requirements of students'emotion,attitude and values;According to the learning situation,analyze the students'foundation;Textbook analysis,determine the unit objectives,the formulation of classroom teaching objectives;Make clear the application value of the newly granted content;Action verbs are hierarchical;Action verbs are specific and can be operated and realized;The results of actions can be measured and measured.
