Research On The Construction Of The Evaluation System Of Computational Thinking Ability In The Teaching Of University Computer Foundation

Since the professor Wing J M.put forward the concept of computational thinking,in the actual learning life also pay more and more attention to the formation of students use computers to solve problems and the cultivation of innovation ability of thinking,in the university computer foundation course teaching basic requirements,also explicitly proposed the calculation of students thinking ability training requirements,so people also become accustomed to the use of the university computer foundation course to cultivate the students' thinking ability.However,in view of the current situation,most teachers focus on the training method of computational thinking and ignore the result of training.Therefore,this paper puts forward the evaluation of computational thinking ability in the course of basic college computer.The teacher will focus on the training method of computational thinking,and ignore the result of the training,so this paper is aimed at this problem proposed "college computer foundation" curriculum in the evaluation of computational thinking ability.Through the establishment of the evaluation model of computational thinking ability in the teaching of college computer foundation,this paper,on the one hand,provides a reliable standard for evaluating students' level of computational thinking ability.At the same time,the existing computational thinking ability evaluation is mainly paper and pencil tests offline,evaluation work are done by teachers,it not only wastes the resources,increase the teachers' burden,but also may be due to teachers' fatigue phenomenon cause the reason of error,so in this paper,through the university computer foundation teaching in computing the development of thinking ability evaluation system,effectively solves the above problem.Specifically,this paper mainly does the following three aspects:First of all,on the basis of reading and analyzing a large number of literatures about the research content of "evaluation of computational thinking ability",the author proposed the research content and method of this paper,and elaborated relevant theories and concepts of the research,laying a foundation for the following research.Secondly,according to the concept of computational thinking proposed by the information technology curriculum standard drafting group of senior high schools in China in 2017,the evaluation index system is preliminarily constructed,and then a scientific evaluation index system is constructed by consulting experts and revising according to their opinions.Then the relative importance of the two factors was qualitatively compared by experts,and the weight values of each indicator were obtained through quantitative analysis of the results,avoiding the subjective tendency of evaluation.After the completion of index construction and weight distribution,the fuzzy synthesis of students' computational thinking ability was carried out through the students' test scores,and the final result was divided into three levels,which improved the accuracy of quantitative evaluation of fuzzy concepts.Finally,in thinking ability evaluation model on the basis of the calculation,the WeChat web developer platform using WXML,WXSS,javascript,such as development language,and with the aid of the mysql database,through the analysis of the system,design,develop WeChat platform based computing thinking ability in the university computer foundation teaching evaluation system,and applied to practice,through the form of questionnaire to collect students' feedback,prove that this system can satisfy the basic needs of students.
