Research On Self-adaptive Resource Organization Of Network-based Instruction

Major: Computer Application Direction: ICAISupervisor: Pro. Zhang Xiaozhen Author: Bai Yun (2000276)In recent years, there appear in large numbers of Network-based Instruction platforms, but many of them are not satisfactory in personalized instruction, which results in low quality of instruction. The personalized organization of instruction resource, as the important part of personalized network-based instruction, is also not satisfactory. And the shortcomings come as follows: (1). Some platforms neglect the organization of instruction resource; (2). The personalized organization of instruction resource of some platforms is quite simple; (3). There is a vague definition of instruction resource, which is unfavorable for the personalized organization. Aiming to solve the existing problems of the personalized organization of instruction resource, this paper is going to state, by research, that personalized organization is the essential part of personalized network-based instruction; that it is favorable for the personalized organization of instruction resource to define 'Instruction Resource' according to the needs of personalized instruction; that the personalized organization of instruction resource should be integrated with the instruction strategy; that it is an applicable way for the fulfillment of the self-adaptive organization of instruction resource in network-based instruction system to integrate the organization of instruction resource with artificial intelligence and use agent to improve the intelligence of the personalized organization of instruction resource. Based on the above-mentionedidea, this paper provides an instruction resource model and a students model that are fit for the personalized organization of instruction resource. Also, because of the priority of information acquisition of student model, it offers a general approach to integrate the instruction resource with the instruction strategy based on the student model. Besides, the paper proposes a network-based ITS model SAROM (Self-Adaptive Resource Organization Model) using multi-agent technology which can implement the self-adaptive organization of network-based instruction resource. The SAROM firstly determines information of the student's personalized fancy; with that information the personalized instruction strategy can be hence determined. Then SAROM chooses instruction resource that is both favorable for the implementation of instruction strategy and preferential to students as the personalized instruction resource, and further integrate the resource with the instruction strategy and present them to the students. Guided by the designing ideas of SAROM, we have designed a resource organization experiment system (ROES) to verify the functionality of the SAROM personalized organization of instruction resource. And the experiment has proved that the integration of instruction strategy and instruction resource based on the student model can solve the problem of the personalized organization of network-based instruction resource, which can help implement the personalized instruction on network-based instruction platform.
