由於資訊與無線通訊科技的進步,數位學習環境有了很大的轉變,由過去單純的e化與無線上網,發展到具感應功能且可交替運作的無線傳輸元件。這些元件能夠隱藏在各種器具中,並隨時隨地感知學習者的情境,並允許在情境變化中提供無間斷地個人化服務與互動;這樣的學習方式,稱為情境感知無所不在的學習 (Context-Aware Ubiquitous Learning)。近年來許多的研究學者已開始著手研究如何建立與應用U-Learning環境,然而建立情境感知無所不在學習環境所需具備的條件尚無清楚的定義,要提出有效的學習活動設計方法與策略更有相當的困難。因此,在本研究中,我們提出一套支援情境感知無所不在學習活動輔助設計模式,並嘗試運用提出的模式建置一套單晶X光繞射研究人員培訓系統。由實驗的結果顯示,在情境感知無所不在學習環境進行活動,具有「系統性」、「可靠性」及「經濟性」等三大優點,同時對於提高學習成效有相當的助益。
The progress of wireless technologies has brought up a new trend in learning environments, from simply using computers and networks to teach and learn, to a new concept called context-aware ubiquitous learning (context-aware u-learning). A context-aware u-learning environment is able to sense the situation of the learners, and hence provides more adaptive supports seamlessly. Recently, more and more researchers have investigated the development of such as learning environments; nevertheless, the criteria of establishing a u-learning environment have not been clearly defined, not to mention the strategies for conducting effective learning activities. In this paper, we propose a computer-assisted design model for developing context-aware ubiquitous learning activities. Based on the innovative approach, a u-learning environment for training single-crystal x-ray diffraction operations is established. Experimental results show that the “systematic”, “authentic” and “economic” are the remarkable benefits for the equipment of the context-aware u-learning environment. In addition, it is helpful in improving the learning performance of the learners.
