Previous studies have shown that the traditional Knowledge Management System (KMS) composed of document database and discussion forums tends to form a "passive" learning mode. The users of traditional KMS can only acquire knowledge by posting questions and getting responses from the domain experts. The knowledge provided by traditional KMS is usually specific-problem oriented, incomplete, unstructured, and fragmented, which is not only hard to gather but also unable to meet the demands of knowledge learners who desire comprehensive knowledge. In response to the above-mentioned demands, the current study adopts Wiki technology to build a knowledge-sharing platform that provides a complete, editable, and expandable knowledge source. "Project Management" course is selected as a case study to test the applicability of proposed Wiki technology in improving the traditional knowledge acquiring and learning methods. From a questionnaire survey with 40 participants from the undergraduate and graduate programs of the Department of Construction Management of Chung Hua University, it's found that more than 70% participants believes that Wiki technology is useful in improving the learning performance of construction management subjects.
