【摘要】：化学新课程改革的核心宗旨是提高学生的科学素养,注重从三维目标去全面发展学生的科学素养。在知识与技能方面提出了解化学科学发展的主要线索,理解基本的化学概念和原理,认识化学现象的本质,理解化学变化的基本规律,形成有关化学科学的基本观念的目标。化学新课程标准的基本理念和目标充分体现了化学概念原理知识教学的重要性,同时也隐含着新的教学要求,概念原理的学习不是简单的记忆,而是达到理解的水平,最终形成有关化学科学的基本概念,要求达到概念转变的层次,这对传统的概念原理教学提出了挑战。微课的特点是主题突出、短小精悍,能解决学习者的认知负荷问题。因此,通过微课改善传统概念原理知识的教学,对提高教师的教学质量和学生的学习质量均有较大的帮助。本课题结合微课在概念原理知识教学中应用研究的理论基础,利用现代教育技术手段提高教学效率,设计精细的微课教学方案并实施,检验其效果,以期为中学化学教师利用微课进行概念原理知识教学提供参考,从以下五个部分展开:第一部分:绪论。阐述了本研究的研究背景、相关研究综述、研究的内容、研究意义与价值、研究的方法。本研究是在教育信息化背景下,为积极响应新课标的呼唤,迎合时代和教学发展的要求,结合文献研究法、实验研究法、案例研究法、问卷调查法探索微课在化学概念原理知识教学中的应用情况。第二部分:核心概念与理论基础。概述了微课,认知负荷理论、认知结构同化理论、可视化理论及其他们对微课概念原理知识教学的价值,为下文的研究提供理论基础依据。第三部分:微课在高中化学概念原理知识教学中的模式构建。该部分对高中化学概念原理知识内容,学生认知特点,微课教学设计原则及微课模式的进行综合分析,为微课在化学概念原理知识教学中的应用提供了相应的技术支撑。第四部分:微课在化学概念原理知识中的实践。根据教学相关理论、高中化学课程标准、微课设计原则等,设计了微课具体应用于高中化学概念原理知识微课课堂教学的方案和相关测试、调查问卷,并分析了调查结果,及时评价了微课在高中化学概念原理知识教学中的应用效果。第五部分:总结与展望。最后,笔者对论文研究进行了总结和反思,综合分析概括了研究的成果,反思了论文的局限,总结研究的成果,并对往后的相关研究提出了相应的展望。
[Abstract]:The core aim of the new chemistry curriculum reform is to improve the students' scientific literacy and to develop the students' scientific literacy in an all-round way. In the aspect of knowledge and skill, this paper puts forward the main clue of understanding the development of chemical science, understanding the basic concept and principle of chemistry, understanding the essence of chemical phenomenon, understanding the basic law of chemical change, and forming the goal of basic concept about chemical science. The basic idea and goal of the new chemistry curriculum standard fully embody the importance of the knowledge teaching of the chemical concept principle, but also imply the new teaching requirement. The study of the concept principle is not a simple memory, but a level of understanding. Finally, the basic concepts of chemical science are formed and the level of conceptual transformation is required, which challenges the traditional teaching of conceptual principles. The feature of micro-class is that the subject is prominent, short-cut, and can solve the problem of learners' cognitive load. Therefore, it is helpful to improve the teaching quality of teachers and students by improving the teaching of traditional concepts and principles. This subject combines the theory foundation of the application research in the concept principle knowledge teaching of the micro-course, using the modern educational technology means to improve the teaching efficiency, to design and carry out the fine micro-course teaching plan, to test its effect. In order to provide a reference for middle school chemistry teachers to use micro-class to teach the knowledge of concept and principle, from the following five parts: the first part: introduction. The research background, related research review, research content, research significance and value, and research methods are described. In the context of educational informatization, in order to respond positively to the call of the new curriculum standard and meet the requirements of the times and teaching development, this study combines the literature research method, the experimental research method, the case study method. This paper explores the application of microcourse in the teaching of chemical concept and principle knowledge by questionnaire. The second part: the core concept and theoretical basis. This paper summarizes the microcourse, the cognitive load theory, the cognitive structure assimilation theory, the visualization theory and their value to the knowledge teaching of the micro-lesson concept principle, which provides the theoretical basis for the following research. The third part: the mode construction of micro-class in high school chemistry concept knowledge teaching. This part gives a comprehensive analysis of the knowledge content of high school chemistry concept principle, students' cognitive characteristics, microcourse teaching design principle and micro class model, which provides the corresponding technical support for the application of micro class in the teaching of chemistry concept principle knowledge. The fourth part: the practice of micro-class in the knowledge of chemical concept principle. According to the relevant teaching theory, chemistry curriculum standard of senior high school, microcourse design principle and so on, this paper designs the scheme and related test of microcourse teaching of chemistry concept principle knowledge in senior high school, surveys questionnaire, and analyzes the result of the investigation. The application effect of microcourse in high school chemistry concept knowledge teaching is evaluated in time. Part five: summary and prospect. Finally, the author summarizes and reflects on the research, analyzes and summarizes the results of the research, reflects on the limitations of the paper, summarizes the results of the research, and puts forward the corresponding prospects for the related studies in the future.
