Research On Performance Evaluation Of Robot Education In Junior Middle School Based On PTA

With the promulgation of national policies and the reform of basic education,robot education has been valued and developed,and has gradually entered primary and secondary school classrooms.Robot education is an education based on design learning and hands-on practical learning.It is a comprehensive and extensive innovative education model.It is an important measure to strengthen the country of education and science and technology in the new era.The existing research on robot education has focused on the connotation and teaching mode of robot education,but the research on evaluation is less,and it is lack of systematicness,which can not evaluate students’ problem-solving ability,practical ability,logical reasoning ability,cooperation and communication ability in the learning process.Based on the "basic factor analysis(PTA)" as the theoretical basis,this study constructs the performance evaluation index system of robot education in junior middle school,which not only enriches the research system of robot education evaluation,but also provides theoretical guidance for students to participate in robot learning.In view of this,this study takes the construction of performance evaluation index system of robot education in junior middle school as the research object,combines theoretical analysis with practical experience,preliminarily formulates the performance evaluation index system,selects the combination of Delphi method and interview method to modify and improve the evaluation index system,and uses analytic hierarchy process to distribute the index weight at all levels on the basis of formulating the index system,Form a complete performance evaluation index system of robot education in junior middle school.Finally,the evaluation system is applied to front-line teaching to verify the effectiveness and operability of the evaluation system.This paper studies from the following aspects:Firstly,the performance evaluation index system of robot education in junior middle school is constructed.Based on the guiding ideology of PTA and the relevant literature of robot education and performance evaluation,combined with the necessary ability elements in the process of junior middle school students’ robot learning activities,this study analyzes the students’ behavior performance,and preliminarily formulates the first-class index,second-class index and the fourth level of each second-class index of the evaluation system.At the same time,in order to ensure the scientificity of the preliminary results,first,the Delphi method is used to modify the proposed indicators,send them to experts in the field of robot education research in the form of questionnaire,collect and analyze expert opinions,screen and optimize the evaluation indicators,and then send the second round of questionnaire to experts,using spss26 0analyze the data results until the experts agree;Secondly,the interview method is used to interview the evaluation index system of students participating in robot education.According to the interview opinions,the indexes and levels are further revised,and finally the indexes and levels of the performance evaluation system of robot education in junior middle school are determined.The index system mainly includes six primary indicators "creative conception","scheme design","model construction","program compilation and debugging","work testing and optimization","work display and communication",19 secondary indicators and four levels of each secondary indicator.Secondly,determine the weight of the performance evaluation index system of robot education in junior middle school.Consult experts and teachers on the weight distribution of robot education performance evaluation indicators in the form of questionnaire,establish a hierarchical structure model and construct a judgment matrix by using analytic hierarchy process,test the consistency of the matrix by using Yaahp software and calculate the relative weight of the indicators,and then calculate the comprehensive weight of each index by using Excel,and finally form a complete PTA based performance evaluation index system of robot education in junior middle school.Finally,the practical application of the performance evaluation index system of robot education in junior middle school.The evaluation index system is applied to practice from a multidimensional perspective.Teachers rank the performance of four students in robot education according to the evaluation index system,and use Kendall harmony coefficient method to statistically analyze the ranking results.The results show that the indexes of the evaluation system have clear meaning and description,and can be applied to practice;Then,the multiple evaluation methods of self-evaluation,mutual evaluation and teacher evaluation are used to evaluate the learning performance of junior middle school students in robot projects.The evaluation results obtained by fuzzy operation are consistent with the evaluation results of teacher interviews,which shows that the evaluation index system constructed in this study can accurately and effectively evaluate the performance level of students,and has strong operability.
