The Application Of Big Concept Teaching Based On Induction And Generalization In Biology Review Of Senior High School

Concept is to think about the common attributes or common characteristics of the objectively existing things,phenomena or ideas,and then form the expression of the cognition of the commonness and essence of things,generally expressed by words or symbols.Organizing teaching around big concept based on understanding the core concept of biology.In this way,the students ‘understanding of biology can be improved effectively,and the knowledge framework of biology can be established on the basis of understanding.This research takes the teachers and students of No.1 Middle School of Shuocheng District,Shuozhou City,Shanxi Province as the research object,and deeply analyzes the students' understanding of concept map through the questionnaire survey.On the basis of consulting relevant literature and integrating teaching experience,this paper puts forward the application of “Big Concept Teaching” and “Induction and Generalization”in senior high school biology review.Shuocheng first middle school class of 2019 is about to enter a senior's object for class 618 and 620 of the teaching practice,construct the review high school biology teaching strategies,to explore a reasonable and efficient review method provides targeted,can draw lessons from the case teaching,to reduce pressure on the high three students,improve the students' grades,college entrance examination has important significance.The main research results are as follows:1.The present situation of students' understanding of the concept map,according to the results of the questionnaire survey is students prefer high school biology,because knowledge is rich,trivial is various,it is difficult to memory,but most students don't realize biology curriculum nature,did not understand the core concepts related tobiological,so most of the students failed to get into the habit of a summary,and still use rote passive study way,leading to loss of marks in the exam is more,after entering the high three,so when students are eager to find an efficient way of learning and strategy,the high school students through teaching materials or teaching during the period of problem sets a better understanding of concept map,And students are also willing to accept the application of concept map in the third grade review teaching.The questionnaire survey of "application effect of big concept teaching and generalization in senior high school biology review" mainly includes three aspects: students' use situation,use effect and future prospect of using concept map.The results show that the combination of large concept teaching with induction and generalization is popular in the class review and students' learning of senior high school.Moreover,after effective training,students have been familiar with the production of concept map and summarized the corresponding knowledge points through group cooperation,which can better improve students' performance and enhance their core biological accomplishment.In a word,the development of this study is not only conducive to the theoretical significance of improving the students' core biological literacy,but also has the practical significance of improving their academic performance and promoting their further study.However,due to the limited time of experiment,it takes time for students to build knowledge network through concept map to summarize specific knowledge points and it is difficult to operate.Therefore,this strategy requires persistence to produce significant results.2.Taking the compulsory textbook of biology for senior high school students published by the People's Education Press as an example and combing with the practice of classroom teaching,this paper,provides a "molecule of cell review teaching design case and the ecological system and its stability review teaching design case,to provide real and effective reference for the teaching information.3.Through teaching practice and comparison with traditional teaching,remarkable results have been achieved in the following aspects.(1)The big concept teaching with the induction summary is conducive to the improvement of students' performance.This kind of teaching mode,can fully mobilize the enthusiasm of students learning,students can take into account different levels,making our students to understand the knowledge in visual image of the figure,and completes the integration of knowledge,cultivate the students' independent thinking,cooperation and communication,efficient expression,comprehensive thinking,such ascore literacy,will eventually help improve the quality of results.(2)the combination of generalization and generalization in the teaching of large concepts is conducive to the integration of students' knowledge.In the process of using large concept teaching,can show both macro and details levels at the same time,in the high school biology class,total review is usually divided into several parts,the knowledge in the teachers' guidance,constructing a concept map,and students based on concept map,help students to each specific knowledge of the concept of integrated together,and form a complete system of knowledge.(3)students should stick to the concept map for a long time.By comparing the results of the mid-term examination and the pretest,found that the difference between the two scores is not big,but pass the final exam grades and test scores before again comparison,it has the obvious difference,so the studentsbuilding knowledge network through the concept map and then summarized the specific knowledge points need to persist in order to produce obvious effect.
