基于角色作业任务的网络教学模型研究与实现

针对网络教学过程中作业呈现出的多媒体化与电子化特点,从作业本体的角度对作业和任务进行了定义与建模,在此基础上提出了作业状态空间的概念,并设计了一种基于角色作业任务的网络教学模型(NERAT).该模型具有以学生为中心、以作业任务驱动的多角色互动的特点,并提供了基于角色的个性化反馈以及基于作业文档集的学习、教学和多元等4种不同层次的反馈策略.它可有效地支持教学管理,同时加强了网络教学过程中的个性化学习与教学的互动性.根据NERAT模型开发的OPEN CLASS网络教学管理软件已投入使用.

Research and Implementation of Network Teaching Model Based on Role-Assignment-Task

In order to cope with the emergence of the multimedia and electronic features in network teaching, the assignment and task were defined and modeled from the ontology perspective in the process of network teaching. The concept of assignment state sace was proposed and a network teaching management model, NERAT (network teaching role-assignment-task) model, was built based on these definitions. NERAT has a number of features with regarding students as the teaching centre and with task-driven multi-roles interaction, and provides four layers of teaching feedback strategies, such as role-based personalization feedback, task documents-based learning feedback, teaching feedback and multi-role feedback. The results of the application of OPEN-CLASS system, which is a network teaching management software platfrom developed according to NERAT, show that the model can improve the personalization learning and mutual interaction greatly in the web teaching process.
