Research On The Design And Application Of PPT Micro Course In The Teaching Of Bioscience History In Senior High School

In view of the shortcomings of the current teaching situation of biological science history in senior high school and in response to the requirements of the era of educational informatization,this topic organically combines the history of science with micro courses,so as to give full play to the educational value of biological science history without occupying normal class hours.The development process of the history of science is presented more truly and vividly in the form of micro courses,so as to better cultivate students’ core literacy and improve students’ interest in biology.The design of PPT micro course can not only enrich the micro course resources of biological science history,but also provide case reference for other high school biology teachers to create micro courses.This topic classifies the history of bioscience in the compulsory part of biology in Senior High School of people’s Education Edition(2019)based on core literacy.According to the difficulty coefficient,it is designed into micro courses of independent learning and micro courses based on flipped classroom.A total of 16 micro courses of history of Bioscience are designed.Taking the establishment of cell theory based on the cultivation of life concept and the flow mosaic model of cell membrane based on the cultivation of scientific thinking and scientific inquiry ability as examples,the author shows the specific production process of micro class design,selects the students of two classes of senior one of Shihezi XX middle school as the experimental class and the control class,and carries out the teaching practice of autonomous learning mode and flipped classroom mode respectively.The effectiveness of the teaching of Bioscience history based on micro course is verified by analyzing the results of the history of science and the questionnaire survey of the students in the experimental class and the control class.Through the processing and analysis of a series of data results,this thesis combs and summarizes the following conclusions:(1)It is feasible to combine the micro course with the history of biological science and apply it to teaching practice.Its feasibility lies in: first,it is supported by relevant educational theories;Second,case teaching has achieved quite good teaching results.Students have shown a high level of satisfaction,acceptance and love for the micro course of this course.(2)It is necessary to combine the micro course with the history of Bioscience and apply it to teaching practice.The necessity lies in that first,it can better solve the shortcomings existing in the current teaching of the history of Biological Sciences in the school.For example,teachers ignore the teaching of part of the history of science due to insufficient class hours,and the single teaching method of the history of science is difficult to stimulate students’ interest in learning the history of science.On the one hand,the micro course of Bioscience history can supplement the content of science history that the teachers of the school do not expand or speak because of insufficient class hours.On the other hand,it also enriches the teaching methods of science history,so as to improve the students’ interest in learning;Second,this teaching practice complies with the teaching requirements of the curriculum standard: the educational value of the history of Bioscience can be fully volatilized through the presentation of micro courses,so as to help students improve the core literacy of biology.
