在進行「問題導向學習」課程時，「畫概念圖」是一個相當關鍵的階段。為了全組學生能共同參與 畫概念圖，我們導入圖表製作軟體CACOO (https://cacoo.com)。CACOO 是線上軟體，公開、免費且方便 取得。CACOO 可以讓概念圖用顏色編碼來識別學生。可以追蹤概念圖檔案編輯歷程並轉換成不同儲存 格式。學生學習使用CACOO 軟體並不困難。學生可藉著網路用自己方便的時間，於同一個概念圖上工 作。藉著畫同一張概念圖，學生可以彼此激勵並建立團隊感。學生可使用概念圖做報告，不必每次列印 且能立即修正。老師可以在網路上隨時看到概念圖畫圖的時間，並知道每位同學作圖時間長短以評估每 位同學的貢獻。本篇報告觀察到學生使用CACOO 軟體來畫概念圖有許多優點，值得將來更多的觀摩與 探討。

When performing problem-based learning (PBL) curriculum, drawing concept map is a very critical stage. For the whole group of students who participated in drawing concept map, we introduced charting software CACOO (https://cacoo.com). CACOO is online software, which is open-access. CACOO can achieve team member identification with the use of color-coding on concept maps. The files of CACOO can be used to track editing process of a concept map and can be converted to different storage formats. Students learned to use CACOO software easily. Students can work on the same concept map using Internet at their own convenient time. By drawing a concept map, students can motivate each other and establish teamwork. Students can use the CACOO files for reports, which do not always have to print out and can be corrected in real-time. The tutor can know the length of time each student use to plot the concept map to assess the contribution of each student. Here report using the CACOO software to draw a conceptual map has many advantages and is worthy of further observations and studies.
