远程教育强调基于网络的自主学习,教学材料的呈现形式则是决定这种学习模式能否有效运行的关键.而现有的纸质教材、学习光盘、课程网页等相对散乱的资源呈现方式给学习者造成一定的困扰,不利于自主学习过程的实现. 远程立体化电子教材应该是支撑整个网络自主学习过程的载体,包括教学资源、教学活动、学习评价和学习激励四个维度. 根据远程教育自主学习条件下教学实施过程的需求,以思维导图统驭微课的形式,设计融合教学资源、教学活动、学习评价等一系列教学实施活动的远程电子教材整体框架. 并针对自主学习动力不足的问题,设计了由外在约束到内在激励的学习动力保障机制,构建适应远程自主学习的教学环境,以期提高远程教育教学质量.%Online autonomous learning is an important learning style in distance education, and the presentation of teaching resources is the key of this learning model. The existing teaching resources, such as paper textbooks, VCDs, and course website, are relatively scattered and to some extent confuse the learners. The electronic textbook should provide the service during online au-tonomous learning, including teaching resources, teaching activities, learning evaluation and learning motivation. Based on the needs of distance learners, a three-dimensional electronic textbook for distance learners is designed, whose form is a mind map and micro courses and which can integrate the teaching resources, teaching activities, learning evaluation, and etc. In order to solve the problem of autonomous learning motivation and improve the teaching quality of distance education, the learning motivation mechanism, from the external constraints to the intrinsic motivation, is designed in this article.
