Design And Practice Of The Middle School Chemistry Unit Work Based On The Overall Goal

Homework is not only an extension of classroom teaching,but also an indispensable bridge between school education and family education,which is conducive to achieving teaching objectives,so homework has a very important position.In recent years,due to the special attention paid to reducing the academic burden of primary and middle school students and the proposal of the “double reduction” policy,homework has become the focus of attention.How to improve the quality of homework design and enrich the forms of homework in a limited time to achieve the goal of reducing the burden and improving the quality and efficiency is the pursuit of teachers' teaching.Based on the theory of education,teaching and learning,this study takes the ninth grade students in a middle school in Fuzhou as the research object,and through the questionnaires,to understand the current situation of junior high school chemistry homework assignment and unit homework design.Based on the questionnaire survey and the full analysis of the relevant literature,this study puts forward the idea of designing the junior high school chemistry unit homework based on the overall goal of the unit.According to the characteristics of the unit homework,this study puts forward the idea of homework design,and designs the unit homework case for teaching practicesThe author through the teaching practice,and the pre-test,post-test analysis and comparison as well as later interviews with relevant teachers and students to understand the effectiveness of practical teaching.On the basis of practice summary,the following conclusions are drawn:(1)Designing homework with overall concept to enhance students' higher-order thinking;(2)Pay attention to the real needs of students and give full play to the function of homework;(3)Reasonable and appropriate amount of homework to achieve the effect of reducing quantity and increasing quality.The results of practical research show that the design and practice of junior high school chemistry unit assignment design based on the overall goal proposed in this study are effective,and also provide a reference for front-line teachers' teaching.
