Learning How to Learn (LHTL) is currently one of the world’s most popular massive open online course (MOOC), with nearly 2.5 million registered learners in its first 4 years. Here, we “reverse engineer” the design of the course’s videos to show how creative application of well-known principles of multimedia learning in an MOOC context appear to have fueled the course’s popularity. Gaps in knowledge of multimedia learning are also noted. There have been some 50 years of experience researching effective classroom teaching, but less there have been only 5 years since MOOCs became widespread. The success of LHTL may provide further insight into the importance of the principles of multimedia learning, and how those principles might be practically implemented to improve MOOC making and the general design of instructional videos.

学习方法（LHTL）当前是世界上最受欢迎的大规模开放在线课程（MOOC）之一，在开始的四年中，已有近250万名注册学习者。在这里，我们对课程视频的设计进行了“逆向工程”，以显示在MOOC环境中创造性地应用多媒体学习的著名原理如何促进了课程的普及。还指出了多媒体学习知识方面的空白。研究有效的课堂教学已有50年的经验，但是自MOOC广泛传播以来，只有不到5年的经验。LHTL的成功可以为进一步了解多媒体学习原理的重要性，以及如何切实实施这些原理以改善MOOC的制作和教学视频的总体设计提供进一步的见解。
