Practical Research On Cultivating Students' Ability Of Converting Pictures And Texts In High School Biology Teaching

With the development of curriculum reform and the introduction of the core literacy of biology disciplines,it is required to pay attention to the students' ability to transform biology graphics and texts,and to strengthen students' ability to extract and analyze information.At the same time,image problems and graphics conversion exercises frequently appear.However,in the teaching process,there is a lack of relevant research on cultivating students' "graphic conversion" ability,and there is no discussion on detailed issues.Therefore,research has been carried out on the basis of the theory of graphic-text conversion teaching.Firstly,we used the interview method to investigate the current situation of teachers' graphic conversion teaching and found that most teachers have the awareness of graphic conversion.They believe that it is necessary to cultivate students' graphic conversion ability,but there is no systematic limitation due to objective factors.Training strategy.Then use questionnaire survey and interview methods to investigate the current situation of students' graphics-text conversion ability,and find that the current situation of students' biology graphics-text conversion is not optimistic.The main reasons are: lack of graphictext conversion awareness,weak basic knowledge,lack of training,and integration.Ability is not strong.On the basis of the survey of the status quo,some strategies for cultivating students' graphic-text conversion abilities in high school biology teaching are discussed: in the aspect of graphic-text transfer,use graphic charts frequently to make students pay attention to the learning of graphic charts,and then make good use of them in teaching.Use image charts to teach students to accurately read and read pictures.In terms of text-to-picture transfer,first cultivate students' awareness of text-to-picture transfer,so as to interpret texts with pictures and guide students to draw.In the aspect of graph-to-graph,it changes students' mindset and merges,decomposes,deforms,and simplifies images and charts.Based on the strategies proposed above,relevant teaching practice is carried out,and the analysis of the teaching practice effect is carried out based on the analysis of teaching cases,combined with student test questions and student interviews.The results show that:The ability of students to transfer texts from pictures is improved,and they can read pictures quickly And extract effective information;the students' awareness of text-topicture conversion is improved,and they can perform the conversion more accurately and completely;the student's thinking about the conversion of text to pictures is changed,and they can accurately find the type of conversion for conversion.Finally,the research is summarized,and several teaching suggestions are put forward in combination with teaching practice: cultivate students' awareness of conversion;select appropriate teaching materials;strengthen the conversion training of students;enrich the conversion activities of students.Provide teaching reference for frontline teachers,hoping to effectively promote the professional growth of teachers.
