Based On The History Of Chemistry, The Study Of The Internalization Of The Nature Of Chemistry Teachers

In science education of new century,the nature of science has gradually become a bright spot and hot spot in science education.Domestic and international chemistry curriculum standards all regard the cultivation of students' scientific essence as an important goal of chemistry learning.This not only reflects the changes in the concept of chemical education in the new era,that is,it requires students to not only master the knowledge of chemistry,but also to understand the essence of chemistry.It also reflects the basic requirements for chemistry teachers to implement chemistry education,that is,to guide students to further study chemistry.The basic principles and basic methods form a scientific worldview.At the same time,the precondition for helping students to form a scientific concept of nature is that teachers already have a considerable scientific literacy.Numerous studies have shown that by allowing students to combine the historical and chemical science development trends in the exploration of matter and its changes,students can effectively help students develop a view of the nature of science.However,due to the imperfect scientific literacy of some chemistry teachers,knowledge of the history of chemistry is extremely high.Less,it does not guide students to learn chemistry history and establish a good scientific essence.Therefore,the prevocational education of science for chemistry teachers is particularly important.Therefore,this study will help chemistry normal students complete the internalization of scientific essence through the intervention of chemistry history teaching.Based on the literature review,this study proposes a theoretical model of the nature of chemistry that normal chemistry students need to internalize.It includes fourteen aspects of scientific knowledge,scientific methods,and scientific career.Combined with the 13 scientific development themes selected in the teaching of chemistry history,we compiled the survey questionnaires and interview outlines.According to Vygotsky's theory of internalization and socio-cultural development theory,the author designed a teaching strategy for chemistry history that promotes the nature of the internal chemistry of normal chemistry students.The main strategies include the establishment of a learning community,sub-theme group cooperation,and discussion through the Internet under the class.Individuals construct topics independently.The study focused on the students of the 2014 undergraduatechemistry teacher major.After conducting a 16-week chemical history teaching intervention to promote the internalization of science,they also conducted questionnaire surveys,interviews,interviews,and chemical history.The discussion in the course will be collected and analyzed to understand the process of students' understanding of the nature of science before and after learning the history of chemistry.Through statistical analysis of questionnaire data,an illustrative analysis of interviews and discussion papers in memory,relevant conclusions are drawn: The teaching strategies of chemistry history designed and adopted in this study have a significant impact on the promotion of the three-dimensional structure of students' internal science..After receiving interventions in promoting the internalization of chemical history,chemical normal students have undergone significant changes in the internalization of science.This teaching strategy can effectively help students establish the psychological tools of the essence of science,and can be successfully extracted,expressed,and modified.,improve,and thus complete the three stages of internalization.However,taking into account the students' psychological differences and their acquisition abilities,although the promotion of internalized chemical history teaching strategies can effectively promote the chemistry teachers to build the psychological tools of the nature of science,not all chemical normal students will reach the same level of internalization,nor It will create exactly the same three-dimensional model of the nature of science.
