The Effect Of Concept Mapping On Students' Learning Achievements While Reviewing Electricity In Junior High School

In this study,the method of literature research and the method of equal group experiment were used.In order to explore the influence of the review mode of concept map on the review effect of the electrical lesson of junior high school physics,we adopted the experimental design of the experimental group and the control group,which were tested before and after the experiment,supported by the literature research of the review mode of "concept map".We selected 30 students from each of the two thirdgrade classes in Chongqing X Middle School as the research object,and the electricity course of physics of junior high school 9th grade that published by PEP was the subject of reviewing the teaching contents.Before the experiment,we used "pre-test paper" to test the two classes to ensure the homogeneity of the experimental class and the control class.During the experiment,the experimental group adopted the review mode of "concept map",while the control group adopted the traditional review mode of "teaching+practice".After the experiment,SPSS statistical analysis software was used to investigate the relevant data of the two classes in the following three aspects:1 In order to understand the influence of different review modes on students' ability to master knowledge,the author analyzed the "late test" results of two control classes after using the two review modes,conducted independent sample T test,and analyzed the average and standard deviation of the late test results.2 In order to understand the influence of the review mode of concept map on different types of students,the author divides students into three grades and takes the results of "later tests" as the test variables,and conducts three independent tests of sample T respectively according to the classification of levels.3 In order to understand the influence of review mode of concept map on different knowledge blocks,the author conducted ANOVA test on the scores of 6 knowledge blocks,and compared the significant differences between before and after review of different knowledge blocks.Based on the survey results of the above three aspects on the two review modes,the following main conclusions can be obtained:1 The two review modes have beneficial effects on students' knowledge acquisition,but from the analysis of data,the review mode of concept map is better than the traditional review mode。2 The review mode of concept map has positive effects on students of the three levels,but the effects are different,with the most obvious effect on students of this category who have poor knowledge.3 Among the different knowledge blocks,the review mode of concept map has the most significant influence on the knowledge of the basic concept block.From this,we can see that the "concept map" model is beneficial to the students' review of physics,and is of great help to all kinds of students,all knowledge sectors and the cultivation of students' learning interest and ability.The practical results obtained through this research include:First,the detailed plan and corresponding concept map of reviewing Electric Charge,Electric Current and Electric Current under the review mode of concept map are designed.Second,it summarizes the different influences of the review mode of "concept map" on students of different levels and different knowledge blocks.Thirdly,according to the existing experimental data and experience,the author also puts forward specific suggestions for reviewing physics.First,teachers can reasonably use concept map mode to review physical knowledge,which can improve the review efficiency.Second,before reviewing using the "concept map model",we must understand the specific situation of learning.Third,according to the learning situation and review requirements,it is often necessary to conduct multiple review modes together.Fourth,teachers should establish democratic,equal and dynamic review classes.Fifth,teachers should pay attention to cultivate students' cooperative consciousness and personal ability in the process of guiding students to review courses.Sixth,teachers should emphasize the importance of independent thinking in students' independent activities.Seven,at the same time,teachers should also pay attention to the cultivation of students' innovative ability.
