| As an intelligent teaching system,Extreme Class Big Data can quickly extract student academic data for teachers and students.High school biology requires significantly more practice problems in and out of class compared to junior high school biology,plus the pressure of the college entrance exams,which require a sublimation of one’s learning methods.In order to increase the objectivity of teaching and improve the quality and efficiency of teaching,high school teaching needs the support of polar class big data.Meanwhile,whether the academic data collected by polar class big data can really accurately analyze students’ academic situation and promote academic growth,and finally realize the precise teaching of polar class big data in high school biology is the subject of this thesis.This article takes the high school where the author is located as the case study object,and conducts research on the impact of extreme course big data on precise teaching of high school biology subjects.Fully apply extreme course big data technology to the routine teaching process of high school biology,study specific measures of big data education technology to assist precision teaching,and evaluate its actual effect,providing effective reference and feasible suggestions for high school biology teaching in the context of information education.Firstly,by reviewing the research background and current status of this topic,summarizing the research overview,seeking theoretical support for this study and designing a research framework.Secondly,a questionnaire survey was conducted in the school,analyzing the current application status of extreme course big data in precise teaching of high school biology from both students and teachers,and summarizing the current problems in its application.Thirdly,in response to the current situation of the application of extreme course big data in biology teaching at the school,a strategy is proposed to assist high school biology precise teaching with extreme course big data.Fifthly,in teaching practice,according to the implementation path of pre class preparation-continuous communication between teachers and students in class-emphasis on evaluation and tracking after class,taking the "Material Cycle of Ecosystem-carbon cycle" as an example,new teaching and exercise class practice were carried out from the pre class preparation stage,the precise teaching in class,and the post class evaluation stage.And analyze the practical significance of applying extreme course big data to precise teaching of high school biology by comparing the results of the same test question between the experimental class and the control class.Finally,summarize the achievements of this study and reflect on the shortcomings in the research process.Practice has proven that extreme course big data can effectively assist in precise teaching of high school biology.Teachers understand the real situation of teaching through big data,adjust the teaching structure,and improve the efficiency of teaching;Through precise diagnosis through self-learning,students can improve their learning methods,reduce mechanical problem-solving,and enhance their awareness of self-directed learning. |
