| The "General Senior High School Biology Curriculum Standards(2017 Edition)"was officially promulgated in January 2018.Based on the nature of the biology department,the core literacy of the discipline was condensed.In this context,how to conduct teaching based on the core literacy of biology in each lesson becomes a problem that every teacher needs to think about.Scientific thinking is a favorable tool for students to learn scientific concepts.It runs through the whole process of scientific inquiry and plays an important role in social responsibility "making rational interpretation and judgment".It is an important part of the "key ability" of biological core literacy.Teaching based on question strings is a good way to cultivate students’ scientific thinking.Based on the above analysis,from the perspective of cultivating students’scientific thinking,the research on problem-string teaching is divided into the following parts:Firstly,the literature research method is used to sort out and summarize the relevant research background and current situation of question string and scientific thinking cultivation,and combine the characteristics of this research to determine the concepts of scientific thinking,scientific thinking methods,question string and question string teaching methods;Secondly,the interview investigation method is used to investigate the high school biology teachers of different teaching ages,including the teachers’understanding of the scientific thinking methods,the selection tendency of the teaching methods in the cultivation of scientific thinking,and the dilemmas faced in the cultivation of scientific thinking.Questionnaire survey was used to investigate students in the second year of high school to understand the use of scientific thinking methods by high school students;Then,the scientific thinking method is classified and interpreted,and the corresponding question string design flow is proposed for each type of scientific thinking method.Select the representative chapters of the "Molecular and Cell" and "Generation and Evolution" modules to conduct question-based instructional design,and use specific cases to analyze how to use the question string to cultivate students’ scientific thinking methods and provide reference for teaching practice;Finally,the above research results are combined,the conclusions and shortcomings of the research are summarized,and the research prospects are proposed. |
