The Practice And Research On Promoting The Forming Micro-concepts Of Chemistry In Junior Middle School Based On Information Technology

Forming micro-concepts’ consciousness can affect the way of teaching and the way of learning.It is the focus under the age of education reform.It is very important for students to form micro-concepts because they don’t have good learning methods when they were in junior middle school,especially lack of micro-concepts.So,forming micro-concepts has a big influence on high school education.How can let the students to the world from the perspective of chemistryin on a short period of time and to stay the precious chemical concepts when they are in the era of examination at the same time is worth studying.There aren’t any scheme about how to form micro-concepts when access to a large number of documents.The author decided to study”The practice and research on promoting the forming micro-concepts of chemistry in junior middle school based on information technology” and want to develop a set of teaching resources for teachers’ teaching and students’ learning.This study includes the following six parts:Part one: Clarify the cause of the selected topic and significance of the research.It’s founded that senior one students don’t have good learning methods because they lack of micro-concepts probably.There aren’t any scheme about how to form micro-concepts when access to a large number of documents but some theoretical research.Therefore,inorder to promote the forming micro-concepts of chemistry in junior middle school must increase students’ interest in learning,convert abstract into concrete.Part two: In-depth study of curriculum criteria.combined with the requirements of the curriculum to relist the contents of the particles in the third year chemistry textbook.Through the questionnaire survey,it is concluded that the main reason why the thirdgrade students love chemistry is that they like to do chemical experiments and the reason why they don’t like chemistry is that it is complicated and abstract.Through the investigation and analysis,the third grade chemistry teachers have the ability to operate multimedia.In conclusion,it is feasible to exploit a set of teaching resources for teachers to promote the forming micro-concepts of chemistry in junior middle school based on information technology.Part three: This study expounds the connotation of the forming micro-concepts of chemistry and analyse its distribution in the third period in the textbook.Develop the teaching resources under the guidance of Constructivism theory,Zone of Proximal Development from Vygotsky theory and the “Learning Layer by Layer” theory.Using several key stages as examples.Secondly,design learning strategy based on the theory above.Part four: The plan is completed,showing part of the critical phase of the plan on construction of particles about forming micro-concepts of Chemistry.Part five: Analysis of the results of practice about teaching practice resources.The full teaching resources are used by Shuangliu Yongan middle school,Chengdu Xindu Dafeng middle school,northwest middle school.Then collect data regularly and communicate with teachers and students.Analyze the data of the experimental class and the control class by Spss,Excel and other professional software.The results show that there are obvious differences from unit third between the experimental class and the contrast class in three schools,especially when it comes to micro-concepts.It can be seen that the development of teaching resources plays an important role in promoting the forming Micro-Concepts of chemistry in junior middle School.Part six: Research summary,reflection and outlook.Through the research of practice,we can get the conclusion that the teaching resources which based on information technology can promote the forming micro-concepts of chemistry in junior middle school.But the research object tracking research sample is limited like lack of practice,can be improved and have a further research.
