| The course of examination paper evaluation is an important and special class in biology teaching in senior high school.At present,the promulgation of new curriculum standards guided by core literacy,the promotion of new college entrance examination programs,and the diversified development of test forms in senior high school all put forward new requirements for the quality of test paper evaluation classes.Only by improving the quality of test paper evaluation courses can it be in line with the requirements of the new curriculum standards and the new college entrance examination evaluation system.This thesis takes the teaching and evaluation of biology examination papers in senior high school as the research object.Through the method of literature research,this thesis studies,collates and analyzes the relevant literature of the examination paper evaluation course,so as to fully understand the research results and the latest research trends in this field,which provides theoretical support and research ideas for this research.This study mainly uses the method of questionnaire survey and educational observation to investigate the current situation of the implementation of the evaluation course of biology examination papers in senior high school,and makes a statistical analysis of the survey data,in-depth analysis of the problems existing in the evaluation course of biology papers in senior high school and the potential reasons behind the problems.By summarizing several major problems existing in the current biology examination paper evaluation course,and in view of the existing problems,supported by the educational big data analysis software,this thesis puts forward an efficient and scientific optimization strategy of the examination paper evaluation course.(1)Make use of the analysis function of big data software before class,classify the test questions according to the error rate and knowledge points,accurately group the students according to the specific examination situation,and determine the students who pay special attention and ask targeted questions in class,select variant topics in class according to high-frequency error knowledge points.(2)The way of evaluation in class adopts the questions with low score rate given by teachers and the questions with medium score rate for students’ cooperative exploration,reasonably divides the test questions and the evaluation subjects,so as to change the students from passive acceptance to active construction.(3)After-class consolidation is mainly based on students’ establishment of wrong topic files,teachers’ topic selection papers and teachers’ individual guidance.The establishment of students’ wrong topic files can not only form their own unique learning materials,but also improve students’ autonomous learning ability.Teachers use big data software to select and group papers,which can achieve the effect of consolidation,testing and tracking,and teachers’ individual guidance pays attention to the differences of students.In view of the above optimization strategy,an experimental verification study is carried out in two parallel classes,and a teaching case is generated.The results of this investigation show that,there are the following major problems in the implementation of the evaluation course of biology examination papers in senior high school:(1)The teachers do not pay enough attention to the evaluation of the examination papers.(2)The teachers lack the use of big data’s analysis software.(3)The evaluation is in the order of the examination questions,lack of important and difficult points.(4)The way of evaluation is single,neglecting the main body of students.(5)Emphasizing knowledge,neglecting biological ideas and methods in the process of evaluation.(6)The follow-up link of consolidation after class is weak.In the one-stage educational experiment on the proposed optimization strategy,it is found that the performance of the class with the optimized paper evaluation mode is significantly higher than that of the class with the conventional evaluation mode,which verifies the effectiveness of the optimization strategy.It is proved that the optimization strategy in this study can improve students’ performance and improve the efficiency and quality of evaluation. |
