自主学习任务的导航和自动创建方法研究

ON NAVIGATION AND AUTOMATED CREATION ALGORITHM OF SELF-LEARNING TASKS

网络环境下自主学习是基于计算机网络的自主学习。学习要素由原来基于课堂教学的学习者、内容、技术、教师而重组为学习者、资源、网络学习环境、教师。基本要素的变化使学习支持服务系统的范围更加宽泛。基于此,所谓网络环境下的自主学习是指学习者利用计算机网络提供的学习支持服务系统,根据教师设计的教学要求,自主性地选择学习时间、确定学习目标和学习内容、通过可选择的交互方式主动探究学习过程,实现有意义知识建构的学习方式。为了促进教师在教学过程中的经验交流,增强学习任务的复用,在自主学习系统中添加了知识点体系的概念,并且基于此概念,针对学生的个性化情况,设计了以学习评价为依据的导航算法。系统中还加入了由系统自动生成的学习任务,能够根据学生对知识点的掌握程度,智慧地从题库中抽取题目,自动化地生成任务。

Self-learning in web environment is a computer and Internet-based self-learning.The key learning elements change from learners, contents, techniques and teachers which are based on classroom teaching to learners, resource, Internet learning environment and teachers.The changes in learning elements make the range of study supporting and service system bigger.Based on these, we believe that the so called self-learning in web environment is a learning pattern to realise meaningful knowledge construction that the learners use the study support and service system provided by the computer and Internet and according to the teaching requirements designed by the teachers to choose the study time, determine the learning goal and learning content, and actively exploit the learning process through the selectable interactionmeans, all are autonomously.In this paper, in order to promote teachers’ experiences sharing in teaching process, and enhance learning tasks’ reuse, we add the conception of knowledge point system to self-learning system.Based on the conception and aiming at students’ individuation circumstances, we design a navigation algorithm which takes the learning evaluation for the base.In the system there also adds a type of learning tasks which are generated by the system automatically, the questions can be extracted from question bank intelligentlyaccording to the level of students in mastering the knowledge points, and the tasks are generated automatically.
