摘要
超文本教学材料的路径控制是超文本教育应用中存在的一个重要问题．文中以知识空间理论和一般的关系型超文本数学模型为基础，引入超文本学习状态空间的概念；通过定义学习状态空间的数学模型和学习状态跃迁阈值，实现对状态空间学习路径的控制，避免学生“走弯路”，提高了超文本的教学效果．在这种控制方式下，学生在学习状态内部有充分的自由浏览各个知识点；在学习状态之间学生的浏览则受到合理的控制，从而达到了自由与控制的统一．
One of the important problems for the hypertext education applications is to control the learning paths in hypertext learning materials. The concept of hypertext learning state space based on knowledge space theory and normal relative hypertext mathematical model is introduced in this paper. The learning paths are controlled in the space by using the mathematical model of learning state space and the learning state transition threshold. This helps the students avoid getting lost and improve the teaching effect of hypertext. So, in a learning state, the students have sufficient freedom to browse every knowledge point; but among learning states, students' browsing is under well control. Thus the unity of freedom and control is achieved.
