Research On The Evaluation Of High School Information Technology Quality Course

Computing thinking should be the basic skill that every digital citizen should master.In the era of computer science having a huge impact on human beings,computing thinking has become the basis of education.As the new core accomplishment of information technology course,computing thinking is the key content of information technology teaching in the future.It cannot be ignored in basic education and higher education.Information technology course undertakes the important task of training computing thinking.As an information teacher,it is necessary to master the teaching strategies and methods based on Computational Thinking,and to know how to design the teaching activities of information technology courses to improve self-teaching quality.The development of Computational Thinking in China is relatively short.At present,the teaching research based on Computational Thinking is still in the primary stage,and the research on curriculum evaluation to promote the professional development of teachers is less.Based on this background,this paper explores the basic situation and characteristics of the teaching of Computational Thinking in the time teaching of information technology,so as to help teachers improve their teaching ability of computational thinking.The research mainly uses literature analysis,Delphi method,observation method and case analysis.Through literature analysis,the connotation and characteristics of computational thinking are studied,and the evaluation index of information technology curriculum based on Computational Thinking is preliminarily constructed.In order to further improve the evaluation indicators to make the indicators more scientific and credible,after two rounds of questionnaire interviews,the experts' opinions tend to be consistent,and finally determine the indicators."One teacher and one excellent course" is a national teacher drying activity held by the central audio visual education center,which provides teachers with high-quality courses in various disciplines and regions for learning and reference.The teaching of ministerial high-quality courses to a certain extent represents the higher level courses of regional teaching.In this study,30 ministerial high-quality teaching resources with the theme of algorithm and program design in senior high school information technology courses of national excellent courses are selected for analysis,and the typical teaching process and design of teachers are taken as the research object.Through the analysis of teaching video and courseware resources,the teaching characteristics of the teaching activities of Computational Thinking in the course are explored,and the teaching characteristics of the course are analyzed according to the research In order to provide reference for relevant decision-making and help teachers to improve their professional quality and level,some suggestions are put forward.As the basis of curriculum evaluation,indicators are also a part of this study.They are constructed through literature analysis and expert interviews,which are scientific,feasible and reliable.Based on the index,this paper explores the teaching characteristics of Computational Thinking in the selected excellent courses through the analysis of teaching video.This paper analyzes the teaching characteristics of Computational Thinking from the perspective of the overall teaching level,the gap between practice and theory,teaching methods,etc.,and makes in-depth analysis from two dimensions of "algorithmic thinking" and "inductive thinking",and probes into the actual teaching characteristics of excellent courses through cases.Through the statistics and analysis of the teaching characteristics of 30 courses of computational thinking,we find that there are deficiencies in teaching and teachers' teaching skills need to be improved.Based on the analysis of 20 index dimensions,it is found that the overall level is not very high,and the differences of each index dimension are large,among which the overall teaching level of CT3 is higher than other dimensions,and CT5 is lower than other dimensions.In the teaching methods presented in the excellent course,the teaching method of teaching and group cooperation is more than the inquiry method and game teaching method.In summary,most teachers will summarize the corresponding mode structure and method according to the different knowledge points of the teaching content.Through the case study of the teaching characteristics of "algorithmic thinking",it is found that most teachers will provide students with auxiliary materials to reduce the time and difficulty of coding,but the guidance of auxiliary materials designed by different teachers is not the same.In order to enable teachers to solve the problems found in the research and improve the teaching ability of computational thinking,the research puts forward suggestions for improvement of teaching,hoping that this research can make the future information technology courses play a better role in the cultivation of computational thinking.
