【摘要】：在教育教学领域中,在信息化背景下,视觉表征手段越来越丰富,用视觉表征的手段进行与学科的融合,运用可视化的图表结构来进行讲解、知识建构以及知识梳理,促进隐性知识显性化,显性知识形象化、生动化,促进教学效率的提高,促进学生思维的发展。笔者选取初三化学课程作为研究内容,本文将重点探讨运用知识可视化方法在身边的化学物质、构成物质的奥秘、物质的分类和物质变化的多样性、溶液、化学与生活以及化学实验活动六大主题知识中的运用;在分析初三学习者特征和学科教学内容的基础上设计出适合的知识可视化教学模式图,并在教学实践中进行准实验研究。本研究以两个班级学生为研究样本,分为实验组和控制组,对实验组运用知识可视化教学,对控制组运用传统教学,教学实验时间为一学期。教学实验前,为了更好地实施知识可视化教学,把初中化学中知识点进行可视化教学设计,主要从概念图表、视觉隐喻和知识动画三个方面进行研究,使其贯穿于教学内容中,促进学生意义学习。本研究设计知识测试卷对实验组和控制组分别进行前测和后测,再对实验组的前后测结果、控制组的前后侧结果进行比较和分析。数据结果证明初中化学教学中运用知识可视化能提高教学质量,促进学生对知识的理解与建构。本论文的局限在于以教师的知识可视化代替学生的知识可视化。后期在学生可视化的领域,可以进一步跟踪实验。
[Abstract]:In the field of education and teaching, under the background of information technology, visual representation is becoming more and more abundant. The visual representation is combined with the subject, and the visual chart structure is used to explain, construct and comb the knowledge. In order to improve the efficiency of teaching and promote the development of students' thinking, the author chooses the chemistry course of junior high school as the research content, which promotes the dominance of tacit knowledge, the visualization and vividness of explicit knowledge, and promotes the improvement of teaching efficiency and the development of students' thinking. This paper will focus on the use of knowledge visualization method in the side of the chemical substances, the secret of the composition of substances, the classification of substances and the diversity of material changes, solution, chemistry and life and chemical experimental activities of the six major topics of knowledge application; On the basis of analyzing the characteristics of junior high school students and the contents of subject teaching, a suitable visual teaching pattern of knowledge is designed, and a quasi-experimental study is carried out in the teaching practice. Divided into experimental group and control group, using knowledge visualization teaching to experimental group and traditional teaching to control group, teaching experiment time is one semester. Before teaching experiment, in order to implement knowledge visualization teaching better, The visual teaching design of knowledge points in junior high school chemistry is mainly studied from three aspects: concept chart, visual metaphor and knowledge animation, so as to make them run through the teaching contents. This study designed a knowledge test paper to test the experimental group and the control group before and after the test, and then to the experimental group before and after the test results, The results show that the visualization of knowledge in chemistry teaching in junior high school can improve the teaching quality. The limitation of this paper is to replace students' knowledge visualization with teachers' knowledge visualization.
