    • 觀看影片的問題討論方式 (3/3/15)
      • 觀看影片的問題,原則上將不在課堂上討論,
      • 規劃留到網路的平台之中討論,建議方式如下:
      • 在 1Know 中,每一部影片,
      • 右下角有該影片在 YouTube 上的連結,點選該連結之後,
      • 將您的問題直接 post 到 Youtube 影片下的留言區,
      • 留言格式:
        - 第1行:01:24 (也就是,分:秒)
        - 第2行:您的問題(描述的越詳細越好)
      • 如果有人已經問題同一個問題,您也可以試著用不同方式描述
      • 如果知道答案,或有其他想法,可以試著回覆,
      • 您可以針對問題,或回覆按讚與不讚。

    • 練習題的答案 (3/3/15)
      • 練習題的答案
      • 建議您們可以試著做看看,
      • 然後,將您的答案拍照或掃瞄 post 到 FB 上,
      • 然後,其他同學一起討論討論。
      • 如果您們都解不出來,
      • 或者是您們的意見相左,
      • 或者是您們的想法有偏差,
      • 我就會出手提供我的解法。

    • 1Know 練習題參考答案 (3/2/15)
      • 在 1Know 的每一練習題的參考答案已經加入課程列表中了。
      • 只要您們回答一個問題之後,
      • 可以直接對答案(如果是選擇題)
      • 如果是問答題,直接進入下一個題目,即是參考答案。
      • 第二單元 (3/9) 的課程編排方式也是如此,
      • 也就是,回答之後,即可自行參考一下答案。
