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

Mathematics teaching objectives is the central of instructional design,which guides the direction of mathematics teaching activities.Under the background of curriculum revolution,construct the evaluation index system and evaluation model of the design of teaching objectives for the new mathematics class in senior high school,on the one hand,it provides the standard for the quantitative evaluation of the design of teaching objectives,on the other hand,it provides some reference of the design of teaching objectives for the new mathematics class in senior high school.The research questions include:(1)What is the reasonable evaluation index system of the design of teaching objectives for the new mathematics class in senior high school?(2)What is the evaluation model of the design of teaching objectives based on the evaluation index system of the design of teaching objectives for the new mathematics class in senior high school?For the construction of the evaluation index system and evaluation model of the design of teaching objectives for the new mathematics class in senior high school,firstly combs the relevant research of the existing of the design of teaching objectives and its evaluation through the literature analysis method,and preliminarily divides the first-level and second-level indexes and corresponding evaluation criteria;Then,the text of the design of teaching objectives for 76 senior high school mathematics excellent classes is analyzed qualitatively by using NVivo11 software,and the main structural elements of the design of teaching objectives are obtained;Then the preliminary index system is transformed into questionnaire form,and the index and evaluation standard are evaluated by expert consultation method,so that the index system can be revised and perfected,and then the expert questionnaire consultation is carried out again after the modification,the weight coefficient of the index system is determined,and the evaluation model of the index system is obtained;finally,the reliability and validity of the index system are tested.The research conclusions include:(1)The self-made ?Evaluation Index System for the Design of Teaching Objectives for the New Mathematics Class in Senior Middle School?consists of three first-level indexes(curriculum standard requirements,mathematics content,learning basis)and nine second-level indexes(unit objectives,overall integration,literacy development,knowledge content,thought method,connection application,knowledge foundation,skill foundation,experience foundation).Through the consistency reliability test of the raters and the calculation of the content validity index I-CVI and S-CVI,the reliability and content validity of the raters in the self-made index system can reach the acceptable level,which can be used as an effective tool to evaluate the design level of the design of teaching objectives for the new mathematics class in senior high school.(2)Based on the evaluation index system and index weight coefficient,the evaluation model of the index system is obtained:I = 0.15T1+ 0.11T2+ 0.17T3+0.13T4+ 0.12T5+ 0.09T6+ 0.08T7+ 0.08T8+ 0.07T9(In which,I indicates the total score of the design of teaching objectives for the new mathematics class in senior high school,T1-T9 the score of each secondary index in turn).Suggestions on the design of teaching objectives for the new mathematics class in senior high school: Make clear the unit objectives,highlight the core accomplishment of mathematics subject,pay attention to the integration of “four bases”;Make clear the use of the action verb of knowledge content,pay attention to the connection application of mathematics knowledge and the cultivation of thought method;Pay attention to the students' knowledge foundation,integrate the ability foundation,and pay attention to the experience foundation.
