Abstract
In e-Learning, the face-to-face communication between instructors and learners are more limited than in traditional learning form. This causes difficulties for the teaching and learning process. Besides, the developing learning materials in the conventional way are also becoming less and less effective to learners. Therefore, building the productive learning contents is one of the main problems for e-Learning systems. In this paper, we deal with the development of learning contents and propose a mathematical model as pedagogical domain knowledge for e-Learning, called Knowledge Graph. Based on pedagogical and teaching analyses, Knowledge Graph is able to ensure logical and complete qualities for necessary standard knowledge of a given curriculum. Especially, the model is useful for undergraduate education in the developing countries such as Vietnam, where the training context needs strong content knowledge, and good procedures for the building of training programs and curricula. It can help educational administrators, pedagogical experts, and instructors to design high quality teaching and learning materials .
Highlights
In e-Learning, the face-to-face communication between instructors and learners are more limited than in traditional learning form
The KNOWLEDGE GRAPH (KG) model is really suitable for the undergraduate education context and even other training forms (e.g. K-12 school, inservice training) for developing countries such as Vietnam [25], where educational systems should improve more and more training programs, curricula and infrastructures
We propose a solution to this problem basing on KG, where the set of prime idea (PI)’s is developed for each course and the relationship and order between the courses are established from the relationship between the PI’s within each course
Summary
E-Learning has been developing rigorously in a handful of formats and effective applications to serve the need for on-line education by instructors and learners. The KG model is really suitable for the undergraduate education context and even other training forms (e.g. K-12 school, inservice training) for developing countries such as Vietnam [25], where educational systems should improve more and more training programs, curricula and infrastructures This training context is a combination of traditional learning and e-Learning, known as Blended-Learning Environment [26], where eLearning system is considered as a learningsupporting system. It needs to have enough strong knowledge base and necessary procedures to build training programs, curricula, on-line courses, including textbooks, lecture notes, and develop learning activities in the system.
