Investigation And Research On The Status Quo And Relationship Of High School Biology Teachers And Students' View Of The Nature Of Science

As the most important aspect in the cultivation of scientific literacy,the view of the nature of science(VNOS)is not only a research hotspot in the field of current science education,but also one of the indicators to evaluate the level of students'scientific literacy.At present,Chinese scholars have done some research on the VNOS.What is the current situation of teachers'and students'VNOS?What is the relationship between the level of teachers'VNOS as the subject of teaching and the level of students'VNOS?Is there some correlation?This study attempts to explore this problem,and tries to provide a new way to improve students'VNOS,but also to contribute some research examples to the topic of this study.To understand the current teacher and student both groups view of the scientific nature of the current situation and the specific related degree between the two groups of nature of science concept,the scope of this study selected in the author and the author's practice school classmate,research object choice basic similar high student and corresponding biology teacher,choose by Liu Jianzhi scholar compiled by the essence of scientific questionnaire research.The paper also records and analyzes the factors related to the VNOS in the teaching design texts of biology teachers.The main results are as follows:1)The current teachers'VNOS generally belongs to the modern VNOS,while the students'VNOS ogenerally belongs to the traditional type.2)There is no gender difference in the level of students'view of the nature of science.3)There was a linear relationship(F_1,9=33.004,P<0.001)between the concept of the NOS of all teachers and students,and there was a positive correlation in all three dimensions.It can be seen that we can improve the students'ideas indirectly by improving the teachers'level of ideas.4)All the teachers,no matter whether they think they know the NOS or not,their score rate in the dimension of"scientific world view"is lower than that of"scientific inquiry"and"scientific career",and the same situation also holds for the students of corresponding professors.Therefore,the essence of science education should pay more attention to the cultivation of the scientific world outlook.(5)Teachers with a higher understanding of the nature of science present more education of the nature of science in teaching design as a whole.Among the three dimensions,the dimension of"scientific inquiry"not only has the highest level of cognition in the questionnaire survey of teachers,but also has the highest frequency of appearing in the teaching design,indicating that teachers have achieved the unity of knowledge and practice in this dimension.
