ABSTRACT In the new “open world” of information, educational systems should involve students in constructing new knowledge of value to a community out of fragmentary information. The already proposed Knowledge Building (KB) approaches typically support only a few general-purpose activities due to the constraints of the utilised web-based environments. To organise and facilitate students’ KB during course activities, this study incorporated services provided by DoosMooc social learning environment into a knowledge transformation model. This approach is completely adapted to an educational context and allows time for iterations, helping students to both contribute to social KB processes and take collective responsibility for improving their understanding of authentic problems. The features provided by the introduced environment support and assess students’ KB activities and facilitate processes of creating, representing, organising, and reviewing different types of knowledge artefacts. The results of a semester-long experiment indicate that the approach and the corresponding instructional design thereof could successfully organise students’ KB activities and facilitate the required interactions. This study reports the impacts of parameters such as learner expertise and quality of shared knowledge on the planned KB processes, and investigates the relationships between students' KB activities and learning achievements.

通过在线学习环境中的社交互动，加强学生的知识建设

摘要 在信息的新“开放世界”中，教育系统应该让学生从零散的信息中构建对社区有价值的新知识。由于所使用的基于 Web 的环境的限制，已经提出的知识构建 (KB) 方法通常仅支持少数通用活动。为了在课程活动中组织和促进学生的知识库，本研究将 DoosMooc 社交学习环境提供的服务纳入知识转化模型。这种方法完全适应教育环境，并允许有时间进行迭代，帮助学生既为社会知识库过程做出贡献，又为提高他们对真实问题的理解承担集体责任。引入的环境提供的功能支持和评估学生的知识库活动，并促进创建、表示、组织和审查不同类型知识产物的过程。一个学期的实验结果表明，该方法及其相应的教学设计可以成功地组织学生的知识库活动并促进所需的互动。本研究报告了诸如学习者专业知识和共享知识质量等参数对计划的知识库流程的影响，并调查了学生知识库活动与学习成绩之间的关系。一个学期的实验结果表明，该方法及其相应的教学设计可以成功地组织学生的知识库活动并促进所需的互动。本研究报告了诸如学习者专业知识和共享知识质量等参数对计划的知识库流程的影响，并调查了学生知识库活动与学习成绩之间的关系。一个学期的实验结果表明，该方法及其相应的教学设计可以成功地组织学生的知识库活动并促进所需的互动。本研究报告了诸如学习者专业知识和共享知识质量等参数对计划的知识库流程的影响，并调查了学生知识库活动与学习成绩之间的关系。
