Practice Research On Precise Teaching Of Junior High School Science Based On Electronic Wrong Question Notebook

"Double Reduction" background,teachers and students still face old challenges,such as teachers’ difficulty in efficiently and comprehensively grasping the situation of each student before class,difficulty in meeting students’ personalized learning needs,and teachers’ lack of effective tools to generate student learning big data,which makes it difficult to carry out accurate teaching at a deep level.How to fully utilize digital and intelligent educational resources,enable teachers to teach accurately and efficiently,and enable students to learn accurately within limited time,has become the primary focus and implementation direction.For students,making good use of their own mistake resources can greatly improve learning efficiency.For teachers,mastering students’ actual learning situations based on their mistake situations,and preparing accurate lessons based on learning big data,can improve classroom efficiency and teaching level.Currently,the research on accurate teaching both domestically and internationally is showing a rapid growth trend,and accurate teaching is being carried out based on big data,information technology means,intelligent learning,etc.However,there is relatively little research on accurate teaching with regard to mistake books.The author believes that electronic mistake books can most effectively solve the dual needs of accurate teaching for teachers and personalized learning for students.Therefore,this article constructs a precise teaching model based on electronic mistake books on the basis of the existing accurate teaching model.Specifically,the electronic mistake book application software is used as a tool to realize the first step of automatic recording,the second step of mistake data analysis using the electronic mistake book formed,and the third step of precise adjustment in teaching methods and learning strategies.Taking "exercise explanation" and "review class" as examples,the best practice of precise teaching based on electronic mistake books is presented.Firstly,based on a questionnaire survey,this article found that the current situation of students’ mistake management is poor.Students recognize the value of mistake management,but the traditional way of organizing mistakes leads to students’ energy being dispersed on organizing mistakes rather than solving application mistakes,and subsequent behaviors after organizing mistakes are missing.Therefore,finding a convenient and fast mistake management method is the key.This survey provides reference for subsequent practical research.Secondly,the article uses the Orange Fruit Mistake Book software to record mistakes and form electronic mistake books,and based on mistake big data,special codes are set in school-based assignments,and dot matrix pens are used for grading,to carry out precise adjustment from exercise explanation,variation training,and review classes,etc.,based on mistake books.The purpose of this research is to find a highly efficient and convenient mistake input method and explore whether the precise teaching model based on electronic mistake books can improve the efficiency of teachers’ classroom and students’ learning efficiency.This practical research provides ideas for precise teaching based on big data under the guidance of core literacy,and attempts to make new technology a new starting point for improving teaching efficiency and educational level.It has practical reference value for both teachers and students in the context of "Double Reduction".
