| With the development of new technology,"Internet +" technology has penetrated into all aspects of national economy and people’s livelihood,and further deepened and changed the existing economic development model,posing new challenges to all walks of life.With the development of big data analysis,the education industry has also ushered in the reform of refinement and precision."Precision teaching" is an advanced application of the education theory of "teaching students according to their aptitude" under the background of the development of big data application technology.It is a kind of enrichment,refinement and deepening of teachers’ teaching means.By collecting the data of students’ daily examination situation and analyzing the calculation of the big data of the previous examination data,the educators provide the educational materials for teachers to grasp the students’ learning situation,implement accurate teaching and teach students according to their aptitude,and provide students with independent learning programs.Grade three of senior high school chemistry review is very important in the whole high school stage,not only to strengthen and consolidate the knowledge points we have learned,but also to cultivate the core accomplishment of chemistry and improve the ability of comprehensive problem solving.However,in the actual classroom teaching of chemistry in high school,the cognition of teachers and students often appears dislocation.Usually,teachers explain each topic in detail,but students’ acceptance effect is poor.With the big data analysis,we can show including student error-prone points,focus on the content of various teaching knowledge vulnerabilities,can more effectively assist teachers to further perfect and improve the content of high school chemistry classroom teaching,can be further guide the chemical recitation of the key direction,thereby reducing teachers in chemistry recitation of subjectification,cramming education.To make the teaching of chemistry review more effective,more personalized,more accurate and more targeted,and finally achieve the overall goal of chemistry teaching.In this study,i consulted materials and literature research first,and then carried out a student questionnaire survey and teacher interview,to understand the current situation of chemistry review class in xx middle school,and analyzed the main reasons for this phenomenon.Then,under the guidance of relevant theories and tutors,the precision teaching mode of chemistry for senior three students was constructed based on the big data platform of Zhixue.com,hoping to promote students to improve their knowledge and skills,so as to improve the teaching efficiency of chemistry review class for senior three in XX middle school.The model mainly from three link before,class,after class,the main content is: one is to establish accurate before class the teaching goal,the accurate diagnosis problem,the precise intervention in class teaching,group cooperation study,teachers on typical examples of teaching activities,three is accurate remedy after class,and to the XXX middle school senior chemistry teaching in empirical research.After four months of comparative teaching,the knowledge and skills of students in the experimental class have been improved to some extent,and their group cooperation ability and problem-solving ability have also been developed.Research experiments show that the precision teaching model can improve the teaching efficiency of senior three review to a certain extent. |
