Practical Research On Cultivating Scientific Thinking Of Junior Middle School Students By Using The History Of Biological Science

In order to carry out the fundamental task of building up people by virtue,cultivating students' scientific thinking becomes an important part of cultivating students' biological core accomplishment.And the history of biological science not only shows the achievements of human knowledge,but also reveals the spark of scientists' thinking and the method of inquiry in this process.The history of science first is a history of changing thinking methods,which is contained in the process of scientific inquiry from analysis,synthesis,induction,deduction and so on.Through the teaching of science history,let students follow the footsteps of scientists,experience the way scientists use in the practice of understanding the world,let students master this way of thinking in order to achieve the purpose of cultivating students' scientific thinking.Using literature research method,starting from the current research situation of cultivating students' scientific thinking in the history of biological science at home and abroad,on the basis of defining the history of biological science and the related concepts of scientific thinking,the relationship between the history of biological science and scientific thinking is clarified.Through questionnaire survey and interview method,we can find out the current teaching situation of cultivating students' scientific thinking by using the history of biological science in Yantai,and find out the following problems: first,the teacher's theoretical level is not very high;second,the teacher's excavation depth of the history of biological science in teaching materials is not enough;third,the teaching strategy of using the history of biological science to cultivate students' scientific thinking is insufficient.In view of the above problems,some countermeasures are put forward to cultivate students' scientific thinking by using the history of biological science,including sorting out and analyzing the history of biological science in teaching materials,how to use the history of biological science to cultivate students' scientific thinking steps and teaching strategies.and teaching on this basis design,and provide reference for the teaching practice of first-line teachers.Through the educational experimental method,two parallel classes are selected as the control class and the experimental class respectively to carry on the teachingpractice for one semester,and through the classroom observation method and the paper and pen test to test the teaching feasibility.In the paper and pen test,the students in the experimental class improved significantly in the methods of induction and generalization,model and modeling,and critical thinking.Under the influence of teaching practice time,there was no significant change in deductive and reasoning and creative thinking.In general,the use of biological science history to cultivate students' scientific thinking It's very effective.Finally,from the biological science history content,the practice object,the teaching appraisal and so on aspect,carries on the prospect to use the biological science history to train the student's scientific thinking,in order to train the student's scientific thinking to please climb another high building.
