微课在初中化学小专题复习中的实践方法探析

刘姗姗

【摘  要】“微学习”这一概念逐渐被越来越多的国人所认可，全民教育的实施逐渐渗透进人们的生活与学习中。短小精炼的讲解视频作为微课的重要载体，能够精确且及时地将教师在课堂教学中讲解的每个知识点以及各个教学环节，有效并保质保量地记录下来。其不仅贴合教学实际，还能帮助教师在课堂下引导学生对每个知识点进行进一步的解惑和巩固，起到复习知新的作用。本文将站在教师的角度，就微课在初中化学小专题复习中的实践方法这一主题展开探析。

Exploration and Analysis of the Practical Methods of Micro-Classes in the Review of Junior Middle School Chemistry Special Topics

（Zichuan Experimental Middle School of Zibo City，China） LIU Shanshan

【Abstract】The concept of "micro-learning" is gradually recognized by more and more Chinese， and the implementation of education for all has gradually penetrated into people's lives and learning. As an important carrier of micro-classes， short and concise explanation videos can accurately and timely record every knowledge point and every teaching link explained by teachers in classroom teaching， effectively and with high quality and quantity. It not only fits the teaching practice， but also helps teachers guide students to further resolve and consolidate each knowledge point in the classroom， playing the role of reviewing and learning new things. From the perspective of the teacher， this article will explore the subject of the practice methods of micro-classes in the review of junior high school chemistry special topics.

一、微课在初中化学小专题复习中的教学现状

微课是以简短却富含知识讲解精华的短小视频作为载体，经过后期图像、文字和声音的统一处理所构成的教学工具，能够帮助学生在课下进行自我的学习与检验。该视频在极为有限的时间内将某一知识点讲解清晰且完善，帮助教师尽可能地记录下课堂内外的授课过程。对于初中化学这一学科而言，微课是探究类型的实验学习以及复习的重要教学工具，亦是学生课下能够自我检验和及时解惑的重要学习平台。

探究类型的实验学习作为初中化学学科中复习的重点和难点，微课的出现可以直接帮助教师与学生更顺利地度过知识复习与巩固利用的时光。复习效率的提高、学生实验操作能力的进一步提高，是教师和家长对初中毕业年级的学生共同关注的重要事项。……
