Practical Research On Project-based Mixed Teaching For Computational Thinking In Junior High School Information Technology Courses

In the information age,information technology course,as a highly practical subject,has become the most convenient way to cultivate the core quality of junior high school students’ subjects,especially the computational thinking.However,there are some problems in the actual teaching of information technology courses,such as the classroom is boring,the teaching objectives are too simple,and the students’ enthusiasm is not high,resulting in the students’ learning level still stays at a low level and cannot improve the students’ computational thinking ability.Based on this,this research takes the junior high school information technology course as the teaching content to explore the design and implementation of the mixed teaching of junior high school information technology course.First of all,by sorting out the literature,clarifying the connotation and research status of project-based learning and mixed teaching,starting from the theoretical and practical research of the two teaching modes,put forward the application of project-based learning in junior high school information technology teaching,and analyze the feasibility of implementing project-based learning in combination with mixed teaching;secondly,in the model structure In the construction stage,with reference to the existing project-based learning mode and hybrid teaching mode,with the support of constructivist learning theory,pragmatist learning theory and discovery learning theory,combined with the characteristics and teaching objectives of junior high school information technology courses,we will build a project-based mixed teaching mode suitable for junior high school information technology courses.Compared with the traditional curriculum teaching model,this model is based on the combination of online and offline,carries out project-based learning activities,promotes students’ learning,promotes students’ hands-on practice,and finally points to the achievement of teaching goals.Finally,it designs application cases of project-based mixed teaching models for junior high school information technology courses and carries out quasi-experimental research.Taking the two parallel teaching classes in the first year of a junior high school in Nanchang as the research object,the information technology curriculum of the experimental class is implemented with a project-based hybrid teaching model,and the other class is a control class.After the experiment,the students’ examination results and computational thinking scale were analyzed for data,and the research results were obtained.The research results show that the project-based hybrid teaching model has an obvious effect on the improvement of students’ information technology academic performance;it is effective in improving computational thinking,especially in improving students’ algorithmic thinking and problem-solving ability;interview analysis proves that the students in the experimental class teach the current information technology course.The learning model is positive.The project-based hybrid teaching model built is effective in the practice of junior high school information technology courses,and the adoption of this model can achieve better teaching results.
