Research On The Practice Of Chemistry Homework Design Based On The Development Of Cognition

Research shows that.Promote students to understand the development of chemistry teaching for developing students' ability of understanding the physical world from the perspective of chemical,promote students to use chemical knowledge and scientific methods to analyze the ability to solve the problem,a positive role in promoting.Homework is closely related to classroom teaching,which is the complement and extension of the classroom,which is an indispensable part of teaching.But it was discovered through investigation.At present,our school's chemistry homework is still"wear new shoes to go the old wayn" the topic basically comes from the exercise book,neat row one.More on the topic of knowledge development,not the students'understanding of development level.So.In order to solve the problems existing in the chemistry homework,improve the quality of after-school homework to meet the students' development needs.In this paper,a case study of the compulsory REDOX reaction is taken as an example to promote students' understanding and development,and carry out the practice study of homework design.This study used literature method to review the literature related to homework design,and combed out the previous exploration of homework reform.On the basis of relevant literature research,combining with the advantages of the first-line teaching,the paper designs an operation of REDOX reaction.The paper analyzes the students'condition through the feedback of homework and the method of post-test.It is found that the students are able to develop the two aspects of cognition and cognition.Studies have shown that.The design of reasonable operation has a positive effect on the development of students' understanding.The design of the REDOX reaction was done.Firstly,we understand the students' understanding of the REDOX reaction,and then change on the basis of the original understanding.Second,the knowledge of matter is more diverse.In addition,through the work design based on the development of cognition,we can master the students' learning situation more carefully,adjust the classroom teaching in time,and improve the students' learning effect.Finally,students'enthusiasm for the design based on knowledge development is increased.The homework is getting better.
