【摘要】 本研究在新课标要求以及信息媒体技术迅速发展的背景下,将化学陈述性知识与可视化方式有机结合起来。在阐述相应理论基础,分析概括化学陈述性知识与可视化方式的概念、特点与功能的基础上,分别对化学陈述性知识与可视化方式进行细分,并提出了不同类型化学陈述性知识所适应的可视化教学策略。选取并设计了化学陈述性各类知识的典型案例,将提出的可视化教学策略应用到实际的教学过程中,旨在帮助学生轻松高效地理解、应用知识内容,并能自主构建知识体系。此外,教师借助多样化的信息技术手段不仅拓宽学生的思路与视野,还能发展学生的创新能力,培养学生的科学素养,实现学生德、智、体、美全面发展。本文共分为五个部分:第一部分:绪论。通过解读新课程标准对九年级化学知识分类教学的要求,结合知识可视化相关理论对教学活动的影响,阐述了本文的研究背景、研究目的及意义、研究方法以及研究思路。第二部分:研究综述和相关理论。主要阐述了国内外“知识可视化”的研究现状,界定了相关核心概念,以及对指导本研究的理论基础进行了简要概述。第三部分:九年级化学陈述性知识可视化教学策略的理论构建。分析总结了化学陈述性知识与可视化方式的类型、特点、功能等,并提出了每一类知识的可视化教学策略。第四部分:九年级化学陈述性知识可视化教学策略实践研究。选取了化学陈述性知识所包含的三种类型知识的代表内容,并依据文中提出的相应可视化教学策略进行教学设计与实践,通过设计课后知识小测试、问卷调查的形式,对实施效果进行了分析。第五部分:研究总结与建议。对研究进行总结,以及对实践教学中存在的问题进行反思并提出一些建议。更多还原

【Abstract】 Based on the new curriculum requirements and the rapid development of information media technology,this study organically combines declarative knowledge with visualization.On the basis of explaining the corresponding theoretical basis and analyzing the characteristics and functions of the chemical declarative knowledge and visualization methods,the chemical declarative knowledge and visualization methods are subdivided,and the visual teaching strategies adapted to different types of chemical declarative knowledge are proposed.By selecting and designing typical cases of various kinds of knowledge,the proposed visual teaching strategy is applied to the practical teaching process,which aims to help students to understand and apply knowledge easily and efficiently,and to build a knowledge system independently.In addition,the teachers not only widen the students’ ideas and horizons by means of diversified information technology,but also develop students’ innovative ability,cultivate students’ scientific literacy,and realize the all-round development of students’ morality,intelligence,body and beauty.This paper will be divided into five parts:The first part:introduction.By interpreting the requirements of the new curriculum standard for the classified teaching of chemistry knowledge in grade nine,combined with the influence of knowledge visualization theory on teaching activities,the research background,research purpose and significance,research methods and research ideas are expounded.The second part:Research Review and related theories.This paper mainly expounds the research status of "knowledge visualization" at home and abroad,defines the relevant core concepts,and gives a brief overview of the theoretical basis for guiding this study.The third part:the theoretical construction of visual teaching strategy of declarative knowledge in grade nine.The types,characteristics and functions of declarative knowledge and visualization methods are analyzed and summarized,and a visualization teaching strategy for each type of knowledge is proposed.The fourth part:the practice research of nine year chemistry declarative knowledge visualization teaching strategy.The representative content of three types of knowledge contained in chemical declarative knowledge is selected.And teaching design and practice are also carried out according to the corresponding visualization teaching strategies proposed in this paper.Through the design of after-school knowledge test and questionnaire survey,the implementation effect is analyzed.The fifth part:the research summary and the suggestion.A summary of the research is made,the problems in practice teaching are reconsidered and some suggestions are put forward.更多还原
