Research Of Information Technology Courses Instructional Design In Senior High School Oriented To The Training Of Computational Thinking

As a product of the information age,computational thinking is an important concept that many researchers at home and abroad are paying attention to,and it is also a research hotspot in information technology education.With the requirement of the new curriculum standard for senior high school for the cultivation of computational thinking,learning computational thinking and mastering the computational thinking method is one of the main contents of the high school information technology education reform.Computational thinking is also regarded as the thinking quality of algorithms and program design modules.The computational thinking teaching in high school algorithms and program design is in the exploration stage both in theory and in teaching practice.Many first-tier cities information technology teachers are in information technology courses.How to carry out the cultivation of computational thinking lacks a holistic understanding and requires further research and practice.The research is based on the high school information technology curriculum,taking computational thinking as the perspective,taking the module as an example,focusing on how to integrate computational thinking into senior high school teaching,and cultivate students' computational thinking.The research question is: how to integrate computational thinking into the design of algorithms and program design and carry out verification? This research starts from the teaching goal,teaching content,teaching implementation process,etc.The instructional design of computational thinking integrates computational thinking into program design as a whole,and pays attention to the formation of computational thinking ability in the process of building program scripts.At the same time,the Scratch course was introduced into the teaching of high school information technology.As a carrier of computational thinking training,it further enriched and perfected the form of computational thinking.The study selected two classes in the first grade as experimental subjects,using literature analysis method,quasi-experimental research method and investigation research method,and carried out teaching case design and implementation of teaching activities through the three themes of "game","animation" and "mathematics".The test questionnaire is issued to test the students' computational thinking and learning attitude,and the programming teaching oriented to computational thinking is continuously revised through classroom observation,student work analysis and classroom teaching reflection.Then,the data is collected and statistically analyzed and verified.Students calculate the development of thinking.Concluded as follow:(1)The research adopts addie instructional design mode combined with computational thinking,starting from the five stages of analysis,design,development,implementation and evaluation,embodying three-dimensional computational thinking(computational concepts,computational practice,computational ideas)and computational thinking in the teaching process.The elements(decomposition,sabstraction,algorithm,induction and evaluation)propose an instructional design frame for the development of computational thinking.(2)According to the proposed frame,the teaching case design of the algorithms and program design content is carried out,and the specific teaching activities are carried out.Through the research on the evaluation method of computational thinking,combined with the development trend of the course evaluation,UK Bebras computational thinking challenge test questions and “Calculational Thinking Level Scale” which are suitable for teaching evaluation are selected as evaluation criteria.(3)Through the analysis of the students' computational thinking before and after the test data,combined with the students attitudes survey and students work evaluation,combined with the investigation of students' learning attitude and the evaluation of students' works,it proves the validity of the instructional design of information technology in senior high school oriented to the cultivation of computational thinking,which can promote the development of students' computational thinking to a certain extent.
