Process Evaluation Research On Practical Teaching Of Secondary Vocational Information Technology Course Based On "Computational Thinking"

In recent years,China has paid more attention to vocational education,so that the secondary vocational education,which was originally in a weak position,has received great attention and development.At present,the teaching evaluation of information technology courses in secondary vocational schools mainly includes formative evaluation and process evaluation.The process evaluation generally takes the content contained in the curriculum objectives and the four aspects of core literacy as the evaluation content,which is relatively comprehensive and systematic,but not so deep and detailed,lack of pertinence,and is not convenient to accurately find out key problems and improve in time.Therefore,this paper focus on the process evaluation research from "Computational Thinking" in the practical teaching of information technology course in secondary vocational schools.First of all,by deeply analyzing the "Computational Thinking",it is determined that defining problems,abstracting task characteristics,establishing structural models,reasonably organizing data,forming solutions,summarizing,checking and reporting results and migrating applications are the objectives of practical teaching,and the content of process evaluation is determined;Secondly,according to the process of allowing students to experience analysis and thinking,experimental verification and repeated adjustment in practice,and gradually form "computing thinking",from the perspective of practical teaching on the cultivation of the core elements of "computing thinking",the practical teaching of information technology course in secondary vocational schools is divided into five links: situation creation and task deployment,guidance and demonstration,practical training,achievement inspection,report,summary,expansion and migration;Thirdly,the process evaluation basis of each link is designed comprehensively,and the process evaluation scale is formulated;Finally,the application effect is obtained through teaching practice,student questionnaire survey and interview,and the conclusion is drawn to verify the scientific rationality and effectiveness of the process evaluation of practical teaching of information technology course in secondary vocational schools based on "Computational Thinking".Based on "computational thinking",the evaluation of the practical teaching process of information technology courses in secondary vocational schools can add new elements to the field of practical teaching evaluation of secondary vocational courses in the field of education,and provide a certain reference for teachers to effectively evaluate the practical teaching of information technology courses.Scientific and effective evaluation helps to realize the double optimization of teaching effect and learning effect,promote reform with "evaluation" and promote reform with "evaluation".
