Research On The Teaching Application Of Visualization Of Conceptual Knowledge In Information Technology Courses

Conceptual knowledge,composed of concepts,principles,theories and models,is a kind of knowledge,and plays an important role in classroom learning.Starting from the information technology course and looking at the current situation of academic research and teaching practice of conceptual knowledge found that the study of the theory of conceptual knowledge in the information technology course is not enough in-depth,mostly concentrated in the teaching and research of procedural knowledge;and that in teaching practice,teaching activities of conceptual knowledge in the information technology course can not get enough attention,and because of its abstract,there is the phenomenon of the students "learningt" and teachers "teaching" that affects the teaching quality of conceptual knowledge of the information technology course.It is necessary to solve these problems,and from the perspective of professor discuss how to use visual means to visualize the conceptual knowledge to improve teachers' teaching quality and promote students' understanding of knowledge and cognition according to the relevant theories of visual teaching.The study analyzed the research status of conceptual knowledge and visualization through literature analysis,defined the related concepts,for example conceptual knowledge and visualization,and combining the teaching practice of the information technology course and the teaching advantages of the visualization,analyzed teaching significance of visualization of the conceptual knowledge of information technology course.Analyzing visualization design theory of the conceptual knowledge from three aspects of foundation,core and implement:the connotation of conceptual knowledge;the selection process of the conceptual knowledge visualization methods-"three analysis" through analyzing application value of "A Periodic Table of Visualization Methods";two kinds of methods of visual rendering through analyzing specific visual objects and visualization purposes,and the advantages and disadvantages of two methods of visual rendering.Analyzing visualization teaching theory of the conceptual knowledge from three aspects of process,key and difficulty,and interpreting the general teaching process,teaching advantages and multiple application value of the conceptual knowledge visualization.Finally,in the case of high school information technology courses,choosing some conceptual knowledge as the teaching content,designing visual teaching,and through the relevant variant exercises checking the effectiveness of visual teaching of conceptual knowledge in the information technology course.The research and practice of the study shows that the visual teaching of the conceptual knowledge in the information technology course is to have a role in promoting teaching.Visualization can transfer abstract knowledge to specific knowledge,can transfer implicit knowledge to explicit knowledge,and is a new way for teachers to present knowledge in teaching.
