資訊:以以下方式呈現一到三行:“當我給出問題時,你告訴我答案。 一乘以二。 答案是什麼?” 如果你聽到任何學生給出錯誤答案,立即糾正答案並重復問題。 然後後退兩步,重新開始。
展示工作表。
一個學生有工作表,另一個學生有答案。
確保學生每分鐘可以寫出 40 個答案。 如果懷疑學生有運動障礙,請測試學生的筆跡。 確保學生在一分鐘內可以寫出 40 個數字(一位數和兩位數)。 如果不能,最好讓學生透過說出整個問題和答案來練習。
讓學生練習兩分鐘或直到他們完成練習部分。 然後進行一分鐘計時(40 個正確問題)。 如果學生能夠在練習中沒有太多錯誤,但不能在一分鐘內完成 40 個問題,那麼將計時分成 15 秒的間隔。 進行 15 秒的計時,直到學生能夠完成 30 秒的計時,然後逐步增加到 45 秒,最後到一分鐘。 循序漸進。 在一個練習中不要重複相同的計時超過兩次。 如果學生能夠透過 15 秒計時所有四個部分的測試,請進行 30 秒的計時測試。 如果學生不能透過 30 秒的計時測試,繼續進行,並認為已透過。 不要讓學生感到厭煩。 學生應該能夠在 1 到 2 次測試中透過。 如果學生持續未能透過測試,請回到練習環節,並確保糾正程式正在執行。 學生可能在練習時學錯了某些數學事實,導致學錯了一兩個數學事實。
在練習過程中,確保完全執行糾正程式。 糾正程式包括
- 老師或夥伴給出正確答案
- 學生正確地重複整個問題和答案
- 學生後退 1-3 個問題
- 如果在糾正程式中給出另一個錯誤答案,從數字 1 開始,再後退 1-3 個問題
