The Application Of Knowledge Visualization In The High School Chemistry Teaching

The 21 st century is a knowledge,the information explosion era,the rapid growth of the information and update,let people have to find a positive grasp of the method of knowledge in order to quickly understand the knowledge and information.At the same time,the challenge of the knowledge,the information explosion era to learners and communicators knowledge also has brought the huge pressure,and has caused the teacher confused how to found in the knowledge of the vast ocean,and select the suitable for students learning,effective knowledge the confusion of the learning method,knowledge visualization visual representation method as the effective ways to solve the puzzle which be paid attention to by an increasing number of experts and scholars.Based on consulting a large amount of related knowledge visualization visual representation method chemical element compound knowledge teaching in high school ",hard work of teaching practice of four months " choose knowledge visualization methods of teaching and teach students to use the method to study"flexiable.In the early stage of the teaching practice,understanding of knowledge visualization in questionnaire of the application in senior chemistry teaching,Later in the teaching practice,to interview and to analyse the students’ achievements of the chemistry exam methods,such as the knowledge visualization is obtained on the students’ interest in chemistry study result and chemistry learning.This article corresponding conclusions from the following three aspects:(1)to father get the situation and potential ability of the chemistry learning understanding of knowledge visualization visual representation methods and potential ability to entitled "knowledge visualization visual representation in the feasibility of the application of chemistry teaching investigation" questionnaire,investigate the experimental classes and that in comparative classes of students and the results of the survey showed that more than 80% of the student can accept knowledge visualization visual representation methods and apply better this method into chemistry learning.(2)to verify the knowledge visualization visual representation methods used in the chemistry teaching,learn to improve students’ chemistry learning,teaching practice for four months.Later in the teaching practice of experimental classes and that in comparative classes the students chemistry learning,this paper compares and analyzes the results and showed that: using the knowledge visualization visual representation methods for chemistry teaching and learning,students’ chemistry learning has significant achievement increase.(3)to verify knowledge visualization visual representation method can improve students’ chemistry learning interest,choose experimental class six students in the interview,and the interview results showed that the student to utilize the knowledgevisualization think learning will become easy and interesting and the students’ become more and more interested in chemistry learning.As a result,students use knowledge visualization visual representation method to learn knowledge,to improve the students’ interest in chemistry learning efficiency and performance,learning and so on which is of great help.Knowledge visualization is also helping teachers and students effective ways to cope with the challenge of knowledge explosion era leisurely.
