Difficulty Engine
讓每一篇篇章,都成為對的挑戰。
分析並調整英語內容,對準你學生的程度——從詞彙、句構到整體閱讀難度。不是判斷「這篇有多難」,而是調到「對這班學生最合適」。

同一篇篇章,對這個班太易,對那個班太難。
一篇文章可能內容很適合你的學生,但是:
- 詞彙太難
- 句子太長
- 推理要求太高
- 篇幅太長
教師通常只能手工修改。SpeakLift 把這個過程變成:
- Understand→
- Measure→
- Adjust→
- Validate
The goal isn't to make English easier. It's to make the challenge appropriate.

難度不只是一個 CEFR 標籤。
CEFR 是有用的參考,但閱讀難度不只取決於詞彙等級。
不要只測量難度。把它調對。
降低語言負擔,而不是降低教學價值。
