A Dynamic Construction Model of e-Learning Materials Suitable for Learners

许多电子学习材料都是根据学生的年级和技能水平进行固定包装的。教师根据自己的意图创作教材是可取的。然而，由于时间的限制，这种创造实际上是困难的。虽然教师经常在实际的教学现场对现有的材料进行定制，但大多数现有的材料都是作为一个专用的包来创建的，因此很难令人满意地修改。针对这些问题，本研究提出了教材动态构建模式。在这个模型中，教材被看作是它们的最小块的集合。这种模式可以将现有的教材片段结合起来，构建出适合学习者的教材。因此，这种模式有助于减轻教师在材料创作上的负担。

Many of e-learning materials are fixedly packaged for grade and skill level of students predetermined. It is desirable for teachers to create teaching materials in accordance with their intentions. However, such creation is practically difficult because of time-constraints. Although teachers often customize the existing materials in actual site of education, most existing materials are difficult to satisfactorily modify since they were created as a dedicated package. To resolve these problems, this research proposed a dynamic construction model of teaching materials. In this model, teaching material is regarded as a set of their minimum pieces. This model enables to construct the teaching materials suitable for learners by combining the pieces of existing materials. Consequently, this model contributes to reduction of teachers' burden in material creation.
