This paper proposes the use of .Cognitive, Object-Oriented Teaching Model・ as a way of enhancing adaptive web-based teaching, learning, and materials construction. The Cognitive, Object-Oriented Teaching Model emphasizes not only the use of learners・ alternative characteristics, but also the resolutions of the relationships between the teaching strategies and the features of materials, using critical cognitive objects, events or explanations and relevant strategies which build adaptively curriculum. There is no single comprehensive adaptively solution that can be suitable for everyone. Learners and Learners・ characteristics in learning will change constantly, so teaching strategies must be adapted in suitable situation.

In this paper we base on a model (Chang, 2003), named Cognitive, Object-Oriented Teaching Model (COOTM) to build an architecture for adaptive teaching/learning environments. Based upon this model, we will integrate methodology for learners・ cognitive characteristics, channels of information communication, presentation types of teaching materials, knowledge management and content management to construct an adaptively web-based curriculum. These will have benefits to solve these inabilities to satisfy the need of the heterogeneous learners. The challenge of an educational system is not only to make studying available to learners at any time, in any ways, and anywhere but also to deliver suitable contents in suitable forms to suitable learners. The adaptively solutions of COOTM will be arranged to learners in complex mix characteristics, attributes of teaching materials, and presentation types in differently cognitive channels during learning processes. For individual learning, we build an adaptive teaching knowledge base to conquer the different features in educational environment. We define the objects of educational environment, and construct the objects with Object-Oriented properties which are inheritance, polymorphism and encapsulation into knowledge base. This object-oriented based approach of decomposing educational factors into COOTM is a channel to refine characteristics of educational environment. And we will explain the functionality, usability, reusability, reliability, and scalability of COOTM. Accordingly, we also design and an adaptive learning system via inference engine accesses contents and teaching strategies from the knowledge base on web-base educational system. Finally, a teaching scenario and empirical evaluation have been done on COOTM to express multilayerBmultifactor authentication and show the model is available.
