Research On Micro-course Design Of Chemistry In Senior Middle School

With the development of science and technology,network technology and teaching beliefs has been closely divided,the rapid development of the network has brought an opportunity for educational reform.In the field of education,there have been the teaching methods such as live teaching,distance teaching and network teaching.With the increasing resources of learning resources,the resources are more convenient and easy.micro-class education has become one of the new hotspot,become a bridge to achieve the transformation of teaching and learning.Teaching students in micro-course,students become the initiative of learning,knowledge processing is the main body of knowledge processing,the teacher is the student learning process of the guide,helpers and leaders.The combination of micro-course and "metal and its compounds" will help students to learn and improve the efficiency of learning chemistry.Through the study of domestic and foreign literature,we understand the development and practice of micro-class at home and abroad,define the related concepts of micro-class,expounds the characteristics of micro-class;micro-course to constructivism learning theory,master learning theory,independent learning theory,Informal learning theory as support,attached to the educational technology,analyzed several typical design patterns of micro-class,enumerated the design process of the micro-class;for the ”metal and its compounds,”the status of micro-class analysis,established the topic Several types of micro-class: pre-class micro-class,experimental inquiry class,review class micro-class,level of micro-class,and the design of the corresponding teaching cases;micro-class implementation,the teacher and student interviews and questionnaires,the results show The micro-course is welcomed by most students and teachers,and the teaching work is very helpful.high school chemistry.The results show that the micro-class can promote the students' self-study and improve the learning efficiency.It is feasible and applicable in the practical high school chemistry teaching,which can help the students acquire the new knowledge and consolidate the old knowledge and realize the independent study.
