基于KM教学法的知识图开发、 教学及评估研究——以《C语言》为例

The Development of the Knowledge Graph%2C Teaching and Its Evaluation Based on KM Teaching Method —Take “C Language” as an Example

信息化社会中，人类学习时间的有限性与知识积累的丰富性之间的矛盾日趋尖锐，针对这一矛盾，KM教学法主张在教学过程中融入知识逻辑结构图(K图)和思维形式注记图(M图)，以符合信息化学习方式变革的需求。该文基于KM教学法开发了《C语言程序设计》KM图用于教学中，研发了KMC辅助教学平台，将课程的KM图链接起来。学生可以通过总图点击进入知识点，达到反复强化知识结构、牢固掌握知识和知识间的关系的目的。这种学习方式既有助于在学习、复习或编程等实验前聚焦关键知识点，同时也有助于在课程结束后对本课知识结构留下深刻印象。实验发现中等成绩的学生在使用KM图辅助学习后，其后测基本语法成绩显著高于使用教材学习的对照组学生。最后，文章给出了绘制KM图的建议和展望。

In the information society， a contradiction has been sharp increasingly between the limitations of human learning time and the great richness of accumulated knowledge. In order to solve this contradiction， KM teaching method advocated to integrate the knowledge logic structure diagram (K) and the diagram of Learning in Mind Form (M) in the teaching process. It can meet the demand of change of information learning style. Based on KM， this study developed KMC auxiliary teaching platform， linking the KM graphs of the course. By clicking to enter into the current knowledge point from general drawing， students can strengthen the tower structure of knowledge again and again and further firmly grasp the relationship among knowledge to help to focus on the key knowledge points before experiment， such as in programming. The learning style can improve the students’ learning achievement to improve learning interest， but also help to remember deeply this knowledge structure at the end of the course. Based on a teaching experiment， the study found that the students having middle grade in experimental group were better than the students in control group at the basic grammar of programming. At last， the paper gives some advices on applying KM teaching method.
