双主型ICAI系统的学生模型设计

Design of Student Model in Double-Active ICAI System

为克服传统计算机辅助教学(CAI:Computer Assisted Instruction)不能根据学生认知特点选择教学策略的弊端,构建了双主型智能计算机辅助教学(ICAI:Intelligent Computer Assisted Instruction)系统。重点设计了ICAI系统中全面认知的学生模型,论述了通过诊断获取并记录学生模型数据的过程。该系统的全面认知的学生模型为ICAI系统个性化教学奠定了基础,能激发学生的学习兴趣和动机,在实际教学中发挥其高效性和智能性。

In order to overcome the shortcoming of traditional CAI （ Computer Assisted Instruction）, the main module in double-active ICAI （ Intelligent Computer Assisted Instruction ） system was constructed. A student model in this ICAI system is, all of parameter lists in student model are described. On the designing of diagnostic module and the process of data acquisition was emphasized by diagnosticing. The cognitive student model is the foundition of ICAI system. The ICAI can stimulate interest and motivation, and can improve the effects of instruction.
