【摘要】：随着科学技术水平的不断提高，4G时代业已到来，这也意味着现代教育信息技术将迎来新一轮的飞速发展，广大生物教师借着新时代的“东风”，正在改变着现代生物教育的方法和途径。生物界千姿百态、奥妙无穷，很多生物学知识和问题需要借助形象生动的直观教学手段开展教学，视频则为直观教学提供了丰富的素材。中学生物课程标准要求广大教师要充分开发和利用课程资源，视频作为一种可挖掘的课程资源，深受不同学科教师的青睐，视频应用于中学生物教学改变了传统的教育模式及理念。很多教育专家、名师对视频在学科教学中的应用进行了深入的探究，针对实际教学总结出一些实用的理论和实践参考经验，但纵观其研究成果，视频在生物学科方面的研究相对较少，尤其是视频在初中生物教学中的应用研究屈指可数。因此，本研究结合生物学科特点和课程需要，对视频资源在初中生物教学中的应用进行了探讨。通过查阅、分析、研究大量的博硕士学位论文、期刊及其他参考资料，笔者总结出视频资源的概念、类别和特点，试图通过教学光盘、互联网和自制视频的方法建立一个分类明确的生物视频资源库。以建构主义学习理论、戴尔(Dale)的“经验之塔”理论、数字化学习理论为指导，总结出视频资源在初中生物教学的五大作用：1、有效创设教学情境，激发学生对生物学的兴趣；2、能使知识化繁为简，化深为浅，有助于突破教学重难点；3、丰富课堂信息，拓展学生视野，提高学生学习效率；4、课堂巩固趣味化，帮助学生理解记忆；5、指导实验教学，有利于学生掌握正确的操作方法。并结合前人关于视频教学研究成果，分析整理出视频资源在初中生物教学中应用的五大原则：与教学内容相结合的原则；视频内容的科学性和教育性原则；课堂展示的适时性、适度性、适量性原则；以学生为中心的原则；体现生物学生命性和现代性的原则。笔者通过走访请教一些中学的生物教师，依据人教版生物教材，结合自己的教学实践，，摸索出一些视频资源在初中生物教学中应用的教学方法，比如：视频导入法，视频演示法，游戏视频巩固新知法，相关视频拓展法，与其它教学方法结合使用等简单实用的方法。研究结果为视频资源在初中生物教学中的应用，提供了可行性，为教师高效完成教学任务，提高教学质量，提供了新的途径。本文还总结出视频资源在初中生物教学过程中应用时出现的一些问题，并对其提出针对性的建议。
[Abstract]:With the continuous improvement of science and technology, the 4G era has arrived, which also means that modern educational information technology will usher in a new round of rapid development, the vast number of biology teachers take advantage of the new era "Dongfeng". It is changing the ways and means of modern biology education. Many biological knowledge and problems need to be taught by vivid visual teaching means, and video provides abundant materials for visual teaching. Middle school biology curriculum standards require teachers to fully develop and utilize curriculum resources. As a kind of excavable curriculum resources, video is favored by teachers of different subjects. The application of video to biology teaching in middle school has changed the traditional educational model and concept. Many educational experts and teachers have deeply explored the application of video in subject teaching. This paper summarizes some practical theoretical and practical reference experiences for practical teaching, but throughout its research results, the research on video in biology is relatively few, especially in the application of video in biology teaching in junior high school. Therefore, the application of video resources in junior high school biology teaching is discussed by combining the characteristics of biology and curriculum needs. Through consulting and analyzing, a large number of doctoral thesis, periodicals and other reference materials are studied. This paper summarizes the concept, category and characteristics of video resources, and attempts to establish a clearly classified biological video resource bank by means of teaching CD-ROM, Internet and self-made video. Under the guidance of constructivist learning theory, Dale's "Tower of experience" theory and digital learning theory, this paper sums up the five major roles of video resources in biology teaching in junior high school: 1, and effectively creates the teaching situation. Arousing students' interest in biology can make the knowledge become simple, profound and shallow, help to break through the important and difficult points of teaching, enrich classroom information, expand students' horizons, improve students' learning efficiency and consolidate interest in the classroom. To help students understand memory and guide experimental teaching is helpful for students to master correct operation methods. Combined with the previous research results on video teaching, this paper analyzes the five principles of the application of video resources in junior high school biology teaching: the principle of combining with the teaching content, the scientific and educational principles of video content, the timeliness of classroom display, The principle of appropriateness and moderation; the principle of student-centered; the principle of embodying biological life and modernity. Find out some video resources in junior high school biology teaching application teaching methods, such as: video introduction method, video demonstration method, game video consolidation new knowledge method, related video expansion method, Simple and practical methods used in combination with other teaching methods. The results provide the feasibility for the application of video resources in biology teaching in junior high school, and provide a new way for teachers to complete teaching tasks efficiently and improve teaching quality. This paper also summarizes some problems in the application of video resources in junior high school biology teaching, and puts forward some pertinent suggestions.
