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，我们在教科文组织的世界遗产上开发了两种类型的ESP材料：多媒体电话材料和基于文本的纸质材料。为了创作这些原始材料，我们走访了十几个世界遗产，收集了信息，并记录了包括照片和视频在内的可视媒体。我们在几个课堂上试行了一些开发的材料，并就英语水平、学习材料的呈现顺序、屏幕的观看方式和录音段落的音频征求了学生的意见。试验课的结果证明，混合式学习在单独使用时可以弥补电子学习和纸质面授材料的不足，学习者可以更长时间地保留所学内容。研究结果还对材料的改进提出了建议。

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.
