Research And Application Of Visualization Teaching Strategy Of High School Biology "Molecules And Cells"

With the continuous development of visualization in the field of education,new visualization technology shines brilliantly in educational practice,making classroom teaching interactive,inquisitive and situational.At the same time,the knowledge visualization that focuses on knowledge transfer and creation and the thinking visualization that focuses on developing students’ thinking fit perfectly with the current educational trend,that is,training talents should not only pay attention to the imparting of knowledge,but also pay attention to the improvement of students’ thinking ability,inquiry ability and innovation ability.But the visualization in the field of education are mostly research based on knowledge visualization or visual thinking of only one point of view,there is no better play to the advantages of both,and visualization of thinking in the teaching application of focus too visualization method and ignores the problem of thinking is the kernel,so this study will be in the grasp of knowledge visualization and thinking on the basis of visualization application points,Integrating new visualization technology and related theories,this paper summarizes a set of suitable visualization teaching strategies,in order to better transfer knowledge and develop students’ thinking ability.First of all,in this study refer to knowledge visualization,on the basis of related literature,to the four dimensions of knowledge visualization application What type(knowledge),according to(target),How(How),Who(knowledge receiver)as a starting point,knowledge type on the specific teaching content,integrated into the new 3D knowledge visualization tools,widgets,etc.,Based on biology curriculum standards,textbooks and students’ learning situation,this paper constructs a knowledge visualization teaching strategy of extracting key knowledge from teaching content and selecting appropriate knowledge visualization tools to represent it.Secondly,starting from the main points and subjects of visualization of thinking applied to teaching,this study selects visualization tools of thinking suitable for students,and combines the current situation of students’ biology learning to construct a visualization teaching strategy of thinking,which takes students as the main body,collaborates in drawing before class,showing in class and perfecting the subject mind map after class.Then,the constructed knowledge visualization teaching strategy and thinking visualization teaching strategy are organically integrated and implemented after teachers’ evaluation.Taking two parallel classes of grade one in a high school in Pingdingshan city with no obvious difference in biological learning performance as objects,the visualization teaching practice was carried out for 3 months.Based on the analysis of students’ biological performance,the evaluation results of the chapter end test reflecting the level of scientific thinking and the overall classroom learning situation,it was found that the experimental class taught by visual teaching strategy had higher biological scores than the control class taught by conventional way,and the difference was significant.Reflecting the scientific thinking level of students in the two classes,the experimental class is higher than the control class,and there is a significant difference in two grades.The overall classroom learning of the students of the two classes is better than that of the control class except the "notes".In addition,the subject mind mapping works of group 7 of the experimental class are compared before and after,and it is found that the content presented by the diagrams has made significant progress in breadth,depth and logicality.This indicates that the visual teaching strategy constructed in this study can improve students’ biological learning effect to a certain extent,improve their thinking level,focus their attention on learning,and enhance their autonomy in learning.This paper constructs a visual teaching strategy integrating knowledge visualization and thinking visualization,and carries out specific teaching practice around the strategy,and draws practical conclusions,which provides certain reference value for the application of visualization in teaching.
