Development of Collaborative Learning Product Database for Elementary and Middle School Students

本研究以中小学生为研究对象，对基于项目的学习（PBL）进行研究。在PBL的第一阶段，学生单独设置他们的学习主题，并探索他们的目标。我们将社会建构主义学习理论引入到PBL教学设计中。PBL的学习过程分为四个步骤：“计划”、“学习（研究、探索）”、“展示（呈现、讲述）”和“观看（评估、反思）”。它被称为“PS3”模型“我们注意到谓词词（动词，形容词），以便学生可以输入他们的学习记录和学习产品到协作数据库。根据格语法和PS3模型对部分表语进行了分类。我们为基于项目的学习开发了一个协作数据库。学生将所学知识输入数据库时，可以在网上选择表语词。在数据库中存储了PBL主题、学习记录和学习产品，学生可以使用它来反映自己的学习情况。

In this research we focused on Project Based Learning (PBL) for elementary and middle school students. At the first stage of PBL students set their learning topics individually and explore to their goals. We adopted social constructivism as learning theory into the instructional design of PBL. The learning process in PBL was divided into the following four steps, "Plan""Study (research, explore) ", "Show (present, tell) ", and "See (assess, reflect) ". It was called "PS3" model" We noticed the predicative words (verbs, adjectives) so that the students can input their learning records and learning products into the collaborative database. Some predicative words were classified on the case grammar and the PS3 model. We have developed a collaborative database for Project Based Learning. The students can choose predicative words on the web when they input what they learned into the database. In the database PBL topics, learning records, and learning products are stored and the students can reflect their own learning using it.
