一种基于系统不确定性的主动式知识学习算法

主动式知识学习方法不依赖于先验领域知识,其学习过程受信息系统的内在属性控制,所产生的知识系统能够更客观地表达信息系统的潜在特征和规律。系统不确定性能够有效地控制主动式知识学习过程。基于粗糙集理论,提出一种系统不确定性度量方式,结合Skowron算法,设计出一种基于系统不确定性的主动式决策规则知识学习算法。仿真实验结果表明该算法能够更好地适应系统的不确定性,其综合性能明显优于其他同类算法。

关于学生主动学习的思考

近年来我们进行了创新教育课堂教学的研究,深刻体会到应还给学生学习的主动权,让学生在课堂上真正"活"起来,让学生插上创新的翅膀,自由飞翔。

Role of computer teaching in employment-oriented vocational education

This paper starting from the current issue of computer teaching profession, proposes action-oriented approach for employment -oriented in the computer teaching. The implementation of action-oriented approach breaks the traditional teaching model, combine the learning of specialized knowledge and cultivation of professional expertise organically, and thus enhance the students＇ active learning, the ability to take the initiative to explore, making them develop in professional competence, social skills and personality
