随着“互联网+”时代的到来，智能手机的普及，作为“数字一代”的学生在学习、生活等方面都发生着日新月异的变化。作为一款基础性社交软件，微信深受人们喜爱。传统信息技术教学存在课时少、案例旧、学生人数多、师生课外互动少等问题。 本研究以混合式学习理论为指导，充分挖掘微信和微信公众平台的功能，在分析微信在教育领域研究现状、中职信息技术教学现状以及微信在信息技术教学中的研究现状和现有的信息技术教学模式基础上，以中职信息技术课程《计算机基础知识》和《PPT设计与制作》的部分内容为例，尝试构建了基于微信学习平台支持的中职信息技术教学模式，并将其运用于教学实践中。笔者搭建了“曼妙课堂”微信公众号，通过平台为学习者呈现丰富的教学内容。在实施过程中，结合课堂观察和访谈进一步修订了该教学模式。经过一年多的教学实践，笔者发现：在应用微信学习平台开展教学以后，学生的作业量、优秀率和学习成绩等得到大幅提升, 学习态度得到明显改善。 本研究构建的教学模式将进一步完善国内微信在教学应用方面的相关研究，开发的案例和素材为今后该领域的研究提供可参考的经验。

With the advent of the "Internet +" era, and the popularity of smart phones, as a "digital generation" students are undergoing rapid changes in their learning and life。As a basic social software, WeChat is very popular. There are some problems in traditional information technology teaching, such as less class time, old cases, more students and little interaction between teachers and students after class. Based on the theory of blended learning, this study fully explores the functions of the WeChat and WeChat public platforms, analyzes the research status of WeChat in education, the current situation of information technology teaching in secondary vocational schools, and the research status of WeChat in information technology teaching and the existing teaching model of information technology. This study takes the part of the information technology course 《Computer Basic Knowledge》 and 《PPT Design and Production》as an example, We try to construct a teaching model of secondary vocational information technology based on WeChat learning platform and applies it to the teaching practice. The author built the WeChat public account of “Man Miao Class”, which presented rich teaching content for learners through the platform. In the process of implementation, the teaching model was further revised with classroom observation and interviews. After more than a year of teaching practice, we found that after the application of the WeChat learning platform, the amount of homework and excellent rate of students, academic performance, and learning attitude have been greatly improved. The teaching model constructed in this study will further improve the related research on the application of WeChat in teaching, and the cases and materials developed will provide reference experience for future research in this field.
