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．
The path control of hypertext teaching materials is an important issue in the application of hypertext education. Based on knowledge space theory and general relational hypertext math model, the concept of hypertext learning state space is introduced. By defining the mathematical model of learning state space and learning state transition threshold, the control of state space learning path is realized and avoided Students “detours” to improve the teaching effect of hypertext. Under this control mode, students have full freedom to browse the various knowledge points within the learning state; the browsing of students is reasonably controlled between learning states so as to achieve the unification of freedom and control.
