基于工作流技术的Web协作学习环境的构建研究

Construction of Online Collaborative Learning Environment Based on Workflow Technology

Web协作学习可以消除网络学习的孤独感,发挥群体能动性,提高学习效率。然而,基于交流论坛的协作学习,由于参与者学习行为的独立随意性,不适合协作经验不足和自主学习能力较弱的学习者。而将面对面协作学习远程化的协作学习,由于网络环境下师生数量悬殊过大,不具备推广性和普适性。在缺乏教师实时监督指导的现实前提下,基于工作流技术,笔者提出构建一种适合网络学习者自行实施协作学习的Web协作学习环境。该环境提供学习流以引导学习活动的有序开展,并将协作教学管理经验作为协作学习策略进行存储,监控可能出现的协作困难并提供解决方案。学习者通过遵循Web协作学习环境定义的各项规则,激发学习能动性,提高Web协作学习的有效性。

Online collaborative learning can eliminate online learning loneliness,and encourage group dynamics to improve efficiency.However,the BBS-based collaborative learning,as arbitrary as it may be,is not suitable for learners with insufficient collaboration experience and low autonomous learning ability.It is also not efficient due to the disparity between student and teacher numbers.The authors put forward a collaborative learning environment model advocating autonomous learning.It provides learning flows for orderly learning activities with the guidance of collaborative learning strategies and learning management experiences.Possible learning difficulties are monitored and solutions are suggested.Following the rules defined in the environment,students are encouraged for autonomous learning and learning efficiency is improved.
