Traditionally, teamwork is used as the instructional design for practical projects in business colleges, and students are asked to select a suitable teacher as an adviser. The teacher should be able to assist them in finding a good topic and guide them on using theoretical methodologies to complete their project. However, the traditional instruction method has created challenges for vocational education in Taiwan. These include difficulties in studying research methods, which cause students to feel pressure during the learning process, and difficulties in understanding the syllabi for solving practical problems. This article uses an ontological engineering approach to construct the knowledge ontology of learning subjects. Then, based on the knowledge ontology, it provides practical teaching content into an e-learning system, from which students can learn and practice in an e-learning environment through more structural knowledge and practical experiences. This is an actual case study on vocational education in Taiwan.
We aim at supporting the complex instructional design process for collaborative learning. We adopt learning theories as a basis for designing, analyzing, and evaluating the collaborative learning session. We have brought the ontological engineering technique into our approach. Up to the present, we have built a collaborative learning ontology and formulated collaborative learning models in terms of the ontology. Currently, laying the ontology and the model as basis, we have been conducting a project aiming at developing various kinds of ID support system for collaborative learning. In this paper, we will describe an overview of our Collaborative Learning Ontology, and then present two systems to support the instructional design process for collaborative learning: a group formation support system, and an interaction analysis support system.
We prove that groups acting geometrically on delta-quasiconvex spaces contain no essential Baumslag-Solitar quotients as subgroups. This implies that they are translation discrete, meaning that the translation numbers of their nontorsion elements are bounded away from zero.
