Research On Collaborative Knowledge Construction Of Information Technology Course In Senior High School

With the development of education informatization,the roles of teachers and students have changed in the classroom of primary and secondary schools.Many researchers have proposed that teachers are the guides of knowledge.Students should explore actively and independently in the learning process.With knowledge construction pattern for learning,learners with their original knowledge structure to assimilate new knowledge.In the process of communicating and discussing with peer learners,the understanding of new knowledge is gradually achieved.Assimilate new knowledge on the basis of the original knowledge structure and obtain the meaning of new knowledge.So as to cultivate students’ independent inquiry ability and cooperative communication ability.This study is based on the Shuke platform of cognitive tools for knowledge construction,take the information technology course as an example,creating a learning community,teachers according to the teaching content from the situation import,case teaching,knowledge generation,the empirical analysis,and to ask questions and reflection on five aspects carries on the teaching design,the platform with Shuke to create learning theme,set up for students learning support functions such as teaching plan.Students share ideas and collaborate in the platform,jointly improve the knowledge system,complete the construction of knowledge.Firstly,literature research method is adopted in the research process,through a large number of literature analysis to lay the foundation for the study.Secondly,the method of action research was used to conduct a nine-week teaching practice,and the learning effect and classroom participation of students wereevaluated according to the data of "hot word analysis,problem extraction analysis,participation contribution analysis,and social network analysis" provided in the platform of Shuke.After three rounds of action research,the degree of completion of works reached above good,the network density increased from 0.3 to 0.5,reaching the expected goal,and students’ classroom participation and learning effect were significantly improved.In the process of interaction and exploration,students can jointly acquire new knowledge,solve the problems they encounter at the very beginning,deepen the problems,sublimate their views,and break through the teaching objectives.To sum up,this study makes a breakthrough in the application of collaborative knowledge construction teaching model in information technology courses,and provides some references for scholars who study knowledge construction.
