Development of English materials on UNESCO's World Heritage sites for blended learning and its analysis of their effectiveness

由于混合学习已被证明比电子学习更有效，我们开发了两种类型的ESP材料在联合国教科文组织的世界遗产地：多媒体CALL材料和基于文本的纸质材料。为了制作这些原始资料，我们走访了10多处世界遗产地，收集信息，并拍摄了照片和视频等视频媒体。我们在几个班级中试用了一些制作好的资料，并询问了学生对英语水平、学习资料呈现顺序、屏幕视图和录音段落的意见。试验课程的结果证明，混合学习可以弥补单独使用电子学习和纸质面授材料的不足，学习者可以在更长的时间内保留所学内容。Resoibses还为我们的材料提供了改进建议。

As blended learning has been shown to be more effective than e-learning, we developed two types of ESP materials on UNESCO's World Heritage sites: multimedia CALL materials and text-based paper materials. In order to create these original materials, we visited a dozen World Heritage sites to collect information and took record visual media including photographs and video.We piloted the use of some developed materials in several classes, and asked the students for their opinions regarding the English level, the sequence in which study materials were presented, the view of the screen, and the audio of recorded passages. The results of the trial lessons proved that blended learning could compensate for the shortcomings of e-learning and paper-based face-to-face materials when they are used alone, and that the learner could retain what they had studied for a longer period of time. Resoibses also provided suggestions for the improvement of our materials.
