Research On Teaching Practice Of Promoting The Construction Of Basic Chemistry Concepts Based On BOPPPS Model

In the light of the needs of the times for concept-based education to promote social development,the requirements of the curriculum reform for constructing the basic concepts of chemistry and cultivating scientific literacy,and the demands of chemistry teaching for changing the teaching mode and improving the classroom efficiency,it is very important for chemistry teaching in junior middle school to improve classroom teaching mode and promote the construction of chemistry concept.This research is guided by the construction of basic chemical concepts and takes each link in the bopps teaching model as the main line,and designs a teaching route based on the bopps model to promote the construction of basic chemical concepts,the aim is to effectively improve students’ participation in class,promote students’ deep understanding and transfer of knowledge,improve students’ learning efficiency in class,and cultivate students’ chemical thinking ability.In the early stage of this study,the relevant literature of boppps teaching model and basic concepts of chemistry were read and sorted out by using the method of literature analysis to understand the current research situation,define the relevant core concepts and determine the theoretical basis.Through the investigation and analysis of the current situation of chemistry study of junior middle school students,the main problems in the classroom study of chemistry teaching in junior middle school are understood,and the current cognitive level of junior middle school students is preliminarily defined,through the interview method to junior high school chemistry teachers on the concept of construction and teaching mode of the exchange of interviews,to understand the current situation of junior high school chemistry concept teaching.Based on the previous theoretical basis and investigation results,the construction route of promoting the basic concepts of chemistry based on bopps model is put forward,and selected the third unit of the Ninth Grade Chemistry " The mystery of material composition”in the teaching case design,and in a middle school in Yinchuan,Ningxia,two parallel classes for teaching practice,after the practice,the results of classroom observation evaluation and student learning effect questionnaire were used as qualitative evaluation,and unit test results were used as quantitative evaluation,and the practice effect of promoting the basic concepts of chemistry based on bopps model was obtained,at last,it summarizes and introspects.The results show that the teaching based on the bopps model to promote the construction of the basic concepts of chemistry can improve the students’ interest in learning chemistry,and the students not only have a better and firmer grasp of the concrete factual knowledge,it is also capable of thinking beyond the nature of knowledge,consciously looking at matter and its changes from both a micro and a macro perspective,and being able to transfer the knowledge learned to other problem situations,it gradually forms the independent collation summary and the reflection appraisal ability,promotes the student study way transformation.
