A Practical Study On Training Students' Scientific Thinking Based On "Hypothesis Deduction"

A new round of high school biology curriculum reform clearly points out that to cultivate students' scientific thinking,and "hypothesis deduction" is an important scientific thinking method.Based on this,teachers should not be limited to imparts knowledge,but also need to teach scientific thinking methods,cultivate students' scientific thinking,and implement the core accomplishment of biology.Taking heredity and evolution as an example,the author carries out theoretical and practical research based on "hypothesis deduction method" to cultivate students' scientific thinking.The paper is divided into six parts.The first part selects the literature research method,analyzes the research background;The research status is introduced.The research questions,methods and contents are determined.The purpose and significance of the research are expounded.It defines the value of innovation.The second part adopts the literature research method to study the core concepts,which include hypothesis deduction,thinking and scientific thinking.Sum up the basic link of "hypothesis deduction method";The basic theory is expounded.The third part USES the text analysis method,carries on the analysis to the human teaching edition two compulsory course "heredity and evolution",determines in the compulsory course two the suitable application "hypothesis deduction method" raises the student scientific thinking teaching content,and carries on the teaching content comb.The fourth part adopts action research method and investigation research method to determine the research object,carry out the research process and analyze the results.The research object is two classes of the same level and taught by the same teacher.The research process is divided into three stages,namely the preparation stage,the classroom implementation stage and the evaluation stage.The result analysis includes paper and pencil test result analysis and questionnaire survey result analysis.According to the statistical analysis of the practice data,the results are as follows: before the teaching practice,there is no significant difference in the pre-test scores of the two classes.After the teaching practice,the post-test scores of the two classes were improved,and the post-test scores of the two classes were significantly different from each other,and the scientific thinking performance of each dimension was significantly different.In the fifth part,based on theoretical research and practical research on cultivating students' scientific thinking based on "hypothesis deduction method",combining with the five dimensions of "the concrete expression of middle school students' scientific thinking ability",the feasible teaching strategies of cultivating students' scientific thinking based on "hypothesis deduction method" are proposed.The sixth part is about conclusion and thinking.The conclusion is that the "hypothesis deduction method" can help students to construct knowledge."Hypothesis deduction method" is helpful to train students' scientific thinking.Finally,summarize the research deficiency,carry on the future prospect.
