Research On The Application Of Problem Chain In Deep Learning Of Junior High School Information Science And Technology

The term "deep learning" originated from the research of artificial neural network and was introduced into the field of education in the 1970 s.This theory aims at cultivating students’ comprehensive ability and core accomplishment,and attaches importance to the cultivation of students’ deep understanding and advanced thinking skills.In recent years,it has become a frontier and hot issue in education research.In the classroom observation of educational practice and study,the author finds that students only copy and store knowledge in class.Through electronic questionnaire survey,it is found that junior high school students have problems in knowledge correlation,problem solving and reasonable planning.In classroom teaching,effective questioning is an important way of communication between teachers and students,which can timely mobilize the rapid operation of students’ thinking and promote students’ deep thinking.Through the questionnaire survey on the classroom questioning of junior middle school information technology,it is found that there are problems in the current information technology courses in the frequency of questioning,the difficulty and expression of questioning,the way of questioning and students’ further guidance after answering questions.The teaching design is based on the question chain,and the abstract thinking of information technology is cultivated by the introduction of the situational question chain into the classroom.Teaching new knowledge and cultivating logical thinking of information technology with a ladder type problem chain;Deep learning model thinking is cultivated by inquiry question chain modeling;Develop innovative thinking by expanding divergent problem chain;To deepen the cultivation of critical thinking with the reflective question chain,the cultivation of a variety of thinking jointly promotes the improvement of students’ deep learning ability.On the basis of summarizing the status quo of deep learning and inquiry into question chain at home and abroad,this thesis analyzes the feasibility of applying question chain to deep learning of information technology,and builds a teaching design model of junior middle school information technology based on question chain.By referring to Bloom’s target classification theory,SOLO classification theory and Kraswall’s emotion classification,a deep learning evaluation system with three dimensions of cognition,thinking and emotion was constructed.The teaching design of junior middle school information technology was carried out based on question chain.The pre-test and post-test thesis were prepared based on SOLO classification theory,and three rounds of action research were carried out on students in the experimental class.Constantly improve the instructional design of the question chain,and conduct performance analysis and interviews with teachers and students after action research.The results show that the instructional design based on problem chain can promote deep learning,improve students’ knowledge correlation ability in cognitive dimension,improve students’ problem solving ability in personal dimension,and improve students’ reasonable planning ability in interpersonal dimension.It has a significant effect on changing students’ learning attitude,improving learning effect and cultivating thinking development.
