tailieunhanh - Một tri thức lĩnh vực mang tính sư phạm dùng cho E-learning

Trong bài báo này, chúng tôi đề cập đến việc phát triển nội dung học tập và đề xuất một mô hình toán học về lĩnh vực tri thức mang tính sư phạm dùng cho e-Learning, được gọi mô hình Đồ thị Tri thức (Knowledge Graph). Dựa trên những phân tích sư phạm và lí thuyết dạy học, Đồ thị Tri thức có thể đảm bảo các tính chất đầy đủ và hợp lí đối với lượng kiến thức chuẩn cần thiết của một chương trình đào tạo cho trước. | Science & Technology Development, Vol 14, 2011 PEDAGOGICAL DOMAIN KNOWLEDGE FOR E-LEARNING Duc-Long Le(1), Dinh-Thuc Nguyen(2), An-Te Nguyen(2), Van-Hao Tran(1), Axel Hunger(3) (1) HCM city University of Pedagogy, Vietnam (2) University of Science, VNU-HCM (3) University of Duisburg-Essen, Germany (Manuscript Received on September 21 th, 2010, Manuscript Revised January 13rd, 2011) 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 .

INTRODUCTION 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. Through practical survey, researchers in education show that e-learning has brought plenty of benefits .
