Research On The Construction Of Evaluation Index System For Teaching Objective Design Of Mathematics Concept Course In Junior High School

Teaching objective is the starting point and destination of classroom teaching.The junior middle school stage is a critical period for the development of students’mathematical abstract logic thinking.The scientific teaching objectives guide the teaching of mathematical concept class in junior middle school.At present,there is no evaluation index system focusing on teaching objective design of mathematical concept class in junior middle school.The establishment of a specific evaluation index system of teaching objective design is of great significance to the diagnosis of mathematical teaching objective design level and the instruction of mathematical concept class teaching.The core question of the research:What is the reasonable evaluation index system and its evaluation model for the design of teaching objectives of mathematical concept class in junior middle school?In order to design the evaluation index system for the teaching objectives of junior middle school mathematical concept class,the literature analysis method is firstly adopted to sort out the existing relevant theories and researches,and the theoretical and structural basis of the evaluation index system is obtained.Secondly,considering the textual characteristics of teaching objective samples and combining with expert suggestions,NVivo11qualitative analysis software was used to conduct coding analysis on 76 high-quality teaching objective samples,and the evaluation index system was preliminarily constructed.Then,by soliciting expert opinions twice,the evaluation index and evaluation standard are modified and improved,and the evaluation index weight is calculated and determined to form an evaluation model.Finally,the rationality and reliability of the evaluation index system are verified through the evaluation implementation test,so as to form a reasonable and reliable evaluation index system for the design of teaching objectives of junior middle school mathematical concept class.Research conclusions:（1）The evaluation index system of teaching objective design of junior middle school mathematical concept class has three first-level indicators and nine second-level indicators（including 3 requirements for curriculum standards,3 mathematical contents and 3 learning foundations）,among which nine second-level indicators correspond to nine evaluation criteria.The evaluation index system has good content validity and reliability,and can be used as an evaluation tool to evaluate the teaching objective design of junior middle school mathematical concept class.（2）The evaluation model of teaching objective design of junior middle school mathematical concept class can be expressed by mathematical formula（S represents the total score,and T1 to T9represents the score of each secondary index in turn）:S=0.19T₁+0.15T₂+0.1T₃+0.15T₄+0.09T₅+0.11T₆+0.09T₇+0.08T₈+0.04T₉Teaching objective design suggestions:Meet the requirements of compulsory education curriculum standards,use measurable and evaluable verbs to express the degree of achievement;Reflect the development goal of junior middle school students’ability and literacy;Explain the operation and behavior conditions that students need to carry out in the process of learning mathematical concepts;Focus on the essence of mathematical concepts and clarify the conceptual system by referring to related concepts;Pay attention to the specific areas of application of mathematical concepts;Strengthen the core literacy value of mathematics such as mathematical abstraction and logical reasoning in concept teaching;Grasp students’level of mathematical knowledge preparation;Focus on the specific mathematical skills of junior middle school students;In line with junior middle school students’experience and ability level of mathematical activities.
