課堂模式Classroom
選一課，開一個房間，全班用四個英文字母加入。上課期間你看到誰做到哪一題、誰連續答錯；下課出一張全班診斷。 Pick a lesson, open a room, and the class joins with four letters. While they work you see who is where and who is stuck; at the end you get one diagnosis for the whole class.
叫全班開 librarysmash.com，按「加入課堂」，輸入這四個字母。
Have the class open librarysmash.com, press Join a class, and type these four letters.
或者派這條連結or hand out this link
全班答錯了什麼What the class got wrong
學生不需要帳戶。系統只記下他們自己輸入的暱稱，以及這一課答對了多少題，沒有姓名、電郵或裝置紀錄。房間在開課十二小時後自動刪除，收卷後亦不再接受新的作答。要保存結果請在下課前列印。 Students need no account. The only things stored are the nickname they typed and how they did on this lesson. No names, no email, no device records. The room deletes itself twelve hours after it opens, and no further answers are accepted once it is closed. Print before the lesson ends if you want to keep the result.
