[[abstract]]The e-Taiwan Program emphasized that e-learning will play the key role of professional training in the development of knowledge-based economy. The trend will exclude disabled people if the e-learning platform doesn't consider accessible presentations, personalized learning sequences and accessibility of assistive technology devices. This research is developing required functional modules of a context-aware adaptive e-learning platform and evaluating web accessibility of learning environment which builds perfect e-learning environments for disabled people. This research framework contains two parts. In the first part, according to the Web Content Accessibility Guidelines (WCAG) 1.0 to evaluate web accessibility of the research object, which is named "Wu Ai Yi Wang" by machine identifications. This research had also asked participants to use improved screen keyboard interfere to evaluate the operational accessibility. Furthermore, this research had used both machine identifications and human checks to evaluate curriculums accessibility of no intelligence impairment. The second part is to design a contextual and adaptive learning platform. In the aspect of context, we refer to learner information package specification so that we can design the disabled learning passport and the system can context aware learning information. In the aspect of adaptive learning, since SCORM Sequence and Navigation is introduced into research, we can determine the learning capacity based on the test result and develop suitable functional modules for adaptive services. The result of evaluating accessibility of learning environment can become a reference for building perfect e-learning environments for disabled people. Furthermore, the disabled learning passport can save labors, time cost and learning experiences portability, but it has to be completed standard by expert evaluations. The effects of a context-aware adaptive e-learning platform are that learner context information can be distinguished, and according to learner profile characteristic and learning capacity, it also provides suitable curriculums and schedules learning path and personalizes learning sequence.
