Research On The Scientific Concept Learning Of Biology In Middle School Supported By Visual Representation Of Knowledge Visualization

Since the beginning of the 21st century,the rapid development of information technology has ushered in an era of rapid accumulation of knowledge.In order to promote the spread of knowledge and understanding,people gradually began to try to a lot of the use of language,more abstract knowledge into a form more easily accepted by people,such as images,animation,etc.,this is the so-called "knowledge visualization,and is used to represent abstract knowledge of these images,animation,etc.,called the knowledge visualization tool,which we usually call it" visual representation ".As knowledge visualization research and application of the visual representation of expanding,its huge role also slowly get fully embodies in the field of education,the teaching staff are increasingly found that if the knowledge visualization visual representation used in a line of teaching,improve the students' interest in learning,reduce the effect of cognitive load,deepen the understanding of advantage.At present,improving citizens' scientific literacy has become a universal trend.To cultivate and improve students' scientific literacy,the foundation is to make students master scientific concepts correctly.In the field of biology,in 2011,the ministry of education promulgated the"compulsory education biology curriculum standard" clearly points to "to improve the biology science literacy",its core is the first to make the students master biology science concept,therefore,how to make students correctly and efficiently biology science concept is the issue of teachers to think constantly.In this paper,the author combines the visual representation of knowledge with the concept of biological science in junior high school,USES the visual representation tool to carry out the teaching design,and applies it to the scientific concept learning of junior high school students,hoping to improve the learning effect of biological science concept of students by using the visual representation of knowledge.This paper is divided into five parts,including research background,research review,practical research,research result analysis and research summary.These five parts represent the author's research ideas and specific practical research process.First in the background,the author of this study was developed based on the current research form the specific research questions and research methods,and in the review of most of the studies related to this paper analyzed combing out the related research in the study of this theory,then the author design the part in the study of practical knowledge visualization visual representation and in-depth front-line teaching practice,and use statistical methods in the analysis of the results after the systematic analysis of the student to carry on the teaching of knowledge visualization effect,finally summarized in the research summary of this paper study results and the shortage of the study and the future.In conclusion,this paper grade seven top volume with junior high school biology "green plants and biosphere cycle" as the research content,in class four,grade seven students as experimental object,respectively,the implementation of the teaching design based on knowledge visualization visual representation and first-line teachers daily use conventional teaching methods,through the analysis of test scores after teaching found that knowledge visualization visual representation to a certain extent,indeed can improve the teaching effect of the scientific concept of learning,and help to cultivate students' creative thinking.
