The major purpose of this study is to develop an architectural design knowledge management learning system with corresponding learning activities to help the students have meaningful learning and improve their design capability in their learning process. Firstly, the system can help the students to obtain and share useful knowledge. Secondly, through extraction, application and creation as well as corresponding learning activities, the students can achieve meaningful learning. Lastly, the system can enable the students to accumulate knowledge and experiences to build their schema automatically and improve their design capability. The technology acceptance model (TAM) analysis results support all the hypotheses of this study, indicating the perceived usefulness and ease of use of the system have a positive influence on the students' willingness to use the system, which also helps to effectively reduce the problem of cognitive overload of the student in their learning process and then improve their design capability.
