近几年来二维条形码已成为最流行的技术之一，而 QR Code 又是其中应用最广泛的一种码型。然而，目前针对 QR Code 的应用大多使用的是承载信息量不太多的中低版本，而级别20以上的承载信息量较多的 QR Code 的研究和应用却很少见。笔者针对程序设计语言及算法课程的教学，提出使用高版本 QR Code 图像对一定字符量的程序和算法代码进行编码存储并印刷在讲义或教材上，使学生在学习过程中可以使用智能手机拍摄和解析出 QR Code 图像中的算法代码，再以专用的代码展示和编辑软件进行彩色、高亮和结构化的演示，并可在浏览器中运行以查看动态的运行过程和结果。这种方式较传统的教材模式给学生学习带来了极大的方便，动态的运行也极大地提高了学习效率，增强了学习效果。

2 - D bar codes have become one of the most popular techniques in recent years,in which QR Code is one of the most applied in practice. However,present applications mainly involve the mid or lower version codes which can only accommodate moderate amount of information,and application of higher version QR Codes, i. e. level 20 or more,is seldom reported. To improve teaching in programming languages and algorithms,this paper proposes to employ higher version QR Code images that can be printed on handouts or textbooks to represent program and algorithm codes that may require a number of characters to represent. When learning,students can photograph the QR Code images with smart phones which can then figure out the program or algorithm code and display them in color,highlighted and structured form by means of special coding editors. Moreover,the code can also be run in a browser to show the running process as well as results dynamically. This new model can bring students plenty of convenience compared with the traditional textbook model. The dynamic running also greatly increases learning efficiency and augments learning effects as well.
