Product update · Scaffold fading and AI feedback
Let writing support fade as independence grows
LangStep connects recent writing signals and teacher scores to fade, keep, or restore scaffold recommendations. Learners can choose feedback scenarios such as incomplete sentences or self-revision, while teachers retain control of trajectory changes.
What changed?
The same amount of help is not useful at every stage: too little support can block a beginner, while too much can prevent independent decisions.
- Builds a scaffold trajectory from recent writing performance and blocking signals.
- Lets teachers confirm or adjust fade, keep, and restore recommendations.
- Adds scenario-based student feedback and a separate teacher marking aid without ghostwriting the response.
Learning example
See the change in context
我想自己修改这句话，再请老师看。
Wǒ xiǎng zìjǐ xiūgǎi zhè jù huà, zài qǐng lǎoshī kàn.
I want to revise this sentence myself, then ask the teacher to look at it.
How to use it
Start with a short text, notice the language you need, and write a response that remains your own. Use support as a next step rather than as a replacement for thinking.
- Read the example
- Write one meaningful sentence
- Use a focused hint if blocked
- Revise and save your version
What LangStep does not do
- A fade recommendation is a support decision, not a measure of overall language ability.
- Signals can be ambiguous, so teacher confirmation remains part of the trajectory.
- AI feedback may be imperfect and gives a next step rather than a finished answer.
