| At present,both at home and abroad are affected by the normalization of the epidemic,but this does not affect the iterative update of technology and network technology,which makes all kinds of information spread rapidly,resulting in an impact on the field of education,and it is particularly important to cultivate talents suitable for the new situation.important.Under this global background,there are some unreasonable aspects of traditional review teaching methods in middle school biology teaching in some areas of our country.It is urgent to explore a way to meet the needs of global talent training,which can enhance students' interest in learning and strengthen biological knowledge.A new way of teaching biology for learning efficiency.This paper selects 56 students in class X of the third grade of a middle school in Guiyang City,Guizhou Province as the research object.On the basis of analyzing the current situation of biology review teaching in middle school,combined with relevant materials such as curriculum standards,textbooks,teaching reference,etc.,to compile a stratified teaching method.High school biology review course guide study plan,applied in teaching practice,and statistical analysis of relevant teaching data:(1)In order to understand the current situation of teachers and students using the stratified study guide case,the method of questionnaire survey was adopted,taking teachers and students of a middle school in Guiyang as the survey object.The frequency of using the case in the new teaching is much higher than that in the review class;among them,only16.67% of the teachers use the case in the review class,but the number of students who use the case for review after class accounts for 16.67%.40.26%,which shows that students are more aware of the auxiliary role of the study guide in review,but the frequency of teachers using the study guide in the review class is not high.In addition,most teachers and students agree that the use of tutorials can enhance classroom participation and interest in biological knowledge learning.(2)In order to verify the teaching effect of the stratified study guide plan,the paired sample T test was used to statistically analyze the students in class X of a middle school in Guiyang City after regular review teaching,and after using the stratified study guide plan for review teaching.,the test scores of the two review modes,the results show that the scores after the use of the stratified study guide for review are significantly improved compared with the scores of the conventional review teaching(t=2.897,P<0.01),the average score increased by 4.7points,the highest There was little change in the score.The lowest score was raised from 30 to 44.Before the experiment,there were students in the three levels of A,B,and C.After the experiment,all the students were distributed in the A and B levels.It can be seen that the review teaching of the stratified study guide case has a greater impact on the C-level students.(3)Before the implementation of the practical teaching of the stratified study guide,randomly check the students of the three levels of A,B,and C in Class X of Senior Three,and count the students' completion and quality in the three aspects of preview,classroom exercises,and after-school exercises.The analysis found that there are obvious differences between the three levels: in terms of preview,from the perspective of overall completion,B>A>C;in class notes,students at level A have strong self-improvement ability,and the completion degrees of the three levels are A>B>C;In terms of after-school exercises,students' completion degree and completion quality are B>A>C.In the teaching practice of carrying out the review of the hierarchical study guide case,the completion degree and completion quality of the above three aspects have changed significantly: in the preview,the number and number of students who did not complete the preview decreased significantly,and most of them were concentrated in the C level;In terms of class notes,due to the integration of the review knowledge points in the layered study guide,the overall completion and efficiency of students have increased significantly;in terms of after-class exercises,students at all levels still have different degrees of completion and quality of exercises,but some students There is even a negative state in the writing of the "Summary of Learning and Thinking" section.(4)Through the summary and analysis of the results of the interviews with teachers and students,it is found that the stratified study guide plan is of great help to teaching and learning,and the teachers and students interviewed all agree that the stratified study guide plan is useful in high school biology review teaching.For example,it can improve the review efficiency;but teachers and students generally report that it is slightly insufficient in reducing the role burden,and there are certain limitations.For example,some teachers think that the design process of the study guide is complicated,and the energy and time costs are high.;In addition,students expect to increase the analysis of classic question types in the hierarchical study guide case used in teaching practice,and to enhance its situational and interesting.(5)Observing the practice class X class using the stratified study guide case for review teaching before practice and in the classroom.After statistical analysis,it was found that: before using the stratified study guide case for review teaching,there were 9 students.Participate in classroom interaction,accounting for 16.1% of the total number of students,and 5 students do things unrelated to classroom teaching,accounting for 8.9% of the total number of students;15 students participated in classroom interaction in the use of tiered study guides for review teaching,Accounting for 26.8% of the total number of students,only 2 students do things unrelated to classroom teaching,accounting for3.6% of the total number of students.It can be seen that the use of tiered study guides for senior high school biology review teaching can improve students' classroom participation,and it is also reflected from the side that the use of tiered study guides can enhance students' interest in learning.(6)This paper finds out the advantages and disadvantages of the tiered study guide through the use of the tiered study guide before and after the review of grades,assignments,and classroom observations,and uses the interview method to find the advantages and disadvantages of the tiered study guide.The "Example Analysis" module meets the suggestions put forward by students,thereby improving the practicability of the layered study guide plan;the "Consolidation Exercise" and "Expansion Improvement" modules are combined to reduce the number of exercises,and try again to reflect that the layered study guide plan is correct.Students' homework burden is reduced.Finally,the use of the "Study and Thinking Summary" module is improved,and the hierarchical study guide plan is used to strengthen the communication between teachers and students,so that teachers can better understand students. |
