【摘要】：生物学是一门以实验为基础的学科,实验教学是生物教学的一个重要组成部分,要上好生物课不仅要进行理论课的教学,还必须进行实验教学。如果能上好实验课,不仅能帮助学生正确理解和运用生物学理论知识,还能牢固掌握生物学基本技能,而且还能培养学生的各种能力。目前在初中生物实验教学中,会有很多的因素限制着很多的实验无法按课时完成,比如,实验的周期过长、实验仪器的缺乏。因为种种客观条件的限制,结果导致很多的实验都不能做,老师也就简单示范或简单讲解甚至跳过实验课的教学。因为老师也认为做实验挺麻烦的,准备上一节实验课不容易,又费时又劳累。慢慢的就讨厌上实验课了。这样的一个局面导致的结果是学生不喜欢上生物课,对生物实验知识也把握不牢固,只能是理论的死记硬背。因此,在新课程改革的今天,怎样采取更有效的实验教学途径已经成为一个引人关注的问题。如今在信息科技时代,教育理念不断更新,而且就在这近几年时间刚刚兴起的“微课”“微视频”教学理念,这是一种全新的教学辅助手段,用在生物的实验教学更是一个新的突破。采用微视频进行生物实验部分的教学,不仅能够将抽象的知识具体化,更能激发学生的学习热情。生物实验教学与微视频的有效整合的研究与实践的学习更为重要。初中生物共有4本书,七年级上下册和八年级上下册。其中实验集中在七年级比较多,尤其是七年级下册和学生的生活比较贴切,所以我选择了七年级下册的实验作为研究的材料。本研究通过文献的学习,了解到“微课”“微视频”在国内外的应用,得知微课的发展趋势。认真的分析初中生的认知心理,专心的研究教材以及初中新课程标,认认真真的再次学习心理学教育学知识基础上,借阅广西师范大学图书馆、海南大学图书馆、海南师范大学图书馆等高校图书馆资料,采用文献法对本课题进行研究与实践。本文共有5章:第1章引言部分主要介绍研究背景及国内外微视频在教学领域的研究概况、本研究的目的、意义和研究方法。第2章主要介绍本研究的相关概念与理论基础,对微视频、实验教学等核心概念进行介绍,学习微学习理论、教育传播理论等。第3章是本研究的重点,主要介绍了基于初中生物课程(人教版)标准、初中生物学科内容的特点以及初中学生认知发展的特点的基础上进行了实验微视频的设计及教学设计。同时还介绍了制作实验微视频的原则,抓屏软件的简单介绍,以及制作实验微视频的流程和生物实验微视频资源的获得途径。第4章是本研究的应用实践,主要介绍了初中生物实验教学与微视频在教学中的应用及结果分析和课堂部分实录。第5章是本研究的总结与反思。
[Abstract]:Biology is a subject based on experiment. Experimental teaching is an important part of biology teaching. It can not only help students to understand and apply biological theory correctly, but also can firmly grasp the basic biological skills, but also can train students' various abilities. There will be a lot of factors that limit many experiments that can't be done according to the class hours. For example, the period of the experiment is too long, the experimental instruments are lacking. Because of the restrictions of various objective conditions, many experiments are unable to be done as a result. The teacher also gave a simple demonstration or a simple explanation or even skipped the teaching of the experimental class. Because the teacher also thought that doing the experiment was very troublesome, it was not easy to prepare for an experimental class. It took time and effort. Slowly, I hated taking experimental classes. The result of this situation is that students do not like to take biology classes, and they do not grasp biological experimental knowledge firmly, they can only memorize the theory by rote. In the new curriculum reform today, how to adopt more effective experimental teaching approach has become a problem of concern. Nowadays, in the age of information technology, educational concepts are constantly updated. And just in the last few years, the concept of "micro-course" and "micro-video", which is a new teaching assistant, is a new breakthrough in the experimental teaching of biology. Microvideo is used in the teaching of biological experiments. Not only can the abstract knowledge be concretized, but also the enthusiasm of the students can be aroused. It is more important to study and practice the effective integration of biological experiment teaching and microvideo. There are 4 books on biology in junior high school. Most of the experiments focused on the seventh grade, especially the lower seventh grade books and the students' life. So I chose the experiment of the seventh grade as the research material. Through the study of literature, I learned about the application of "micro-class" and "micro-video" at home and abroad, and learned the development trend of micro-class, and analyzed the cognitive psychology of junior high school students seriously. On the basis of studying the teaching materials and the new curriculum of junior high school seriously and studying the pedagogy of psychology again, we can borrow the library materials of Guangxi normal University, Hainan University, Hainan normal University, Hainan normal University, and other university libraries, such as the library of Guangxi normal University, Hainan University, Hainan normal University, etc. There are five chapters in this paper: the first chapter introduces the research background and the domestic and foreign micro-video research in the field of teaching, the purpose of this study, The second chapter mainly introduces the related concepts and theoretical basis of this study, introduces the core concepts of micro-video, experimental teaching, learning micro-learning theory, educational communication theory, etc. Chapter 3 is the focus of this study. This paper mainly introduces the standard of biology curriculum in junior high school. On the basis of the characteristics of biology content in junior high school and the cognitive development of junior high school students, the design and teaching design of experimental microvideo are carried out. At the same time, the principle of making experimental microvideo and the brief introduction of screen capture software are introduced. As well as the process of making experimental microvideo and the way to obtain microvideo resources of biological experiment. Chapter 4 is the application practice of this research. This paper mainly introduces the application of biology experiment teaching and micro-video in junior high school teaching, the analysis of results and the classroom record. Chapter 5 is the summary and reflection of this research.
