Research On The Cultivation Of Reverse Thinking In Senior Middle School Biology Teaching

The Biological Curriculum Standards for Senior High School(2017)requires students to use scientific thinking methods to understand things,solve practical problems,and incorporate innovative thinking into scientific thinking.Reverse thinking,as an important part of innovative thinking,plays an important role in the cultivation of innovative thinking.Both of the physiology and psychology of the students in the high school are at an important stage of development,they are less affected by the thinking set and have strong plasticity,which is the key period for the cultivation of reverse thinking.The characteristics of biology are obvious;the knowledge is closely related and systematic.A lot of knowledge contains reverse thinking.If it can be used scientifically and effectively,it will be very helpful for the cultivation of students’ reverse thinking.Based on the above analysis,this thesis carried out a research on the cultivation of reverse thinking in biology teaching in senior high school.On the basis of reviewing the current situation of researches on reverse thinking at home and abroad,this thesis investigates the current situation of cultivating reverse thinking in high school biology teaching by means of questionnaires.Through the analysis of the survey results,find out the problem of training in reverse thinking in the first-line teaching.According to the investigation results,the corresponding training strategies are put forward in classroom teaching and exercise training.Finally,two teaching examples are designed to verify the effectiveness of the training strategy.First of all,some senior high school students and biology teachers in Yantai City,Binzhou City were investigated by questionnaires and interviews.Most teachers can deeply understand the connotation of reverse thinking and recognize the necessity of its cultivation,but there are some difficulties in the implementation of teaching.A considerable number of teachers do not know how to cultivate students’ reverse thinking.Students’ understanding of the concept of reverse thinking is one-sided,but they show a strong interest in learning.In view of the above problems,this thesis puts forward the corresponding training strategies in the classroom teaching and exercise training of high school biology,andstrives to provide some practical suggestions for teachers.In order to verify the feasibility and effectiveness of the cultivation strategy,the author combines the curriculum standard with teaching content and students’ learning situation,two cases of reverse thinking cultivation were designed--The Discovery of Plant Auxin and The Regulation of Blood Glucose Balance,and gives a brief evaluation and analysis on them.Finally,it summarizes the major findings and limitations in the research process,and reflects on some difficulties and problems encountered during the study.In a word,the cultivation of reverse thinking is a long-term and systematic project,which requires educators to continuously explore and promote the cultivation of reverse thinking.
