When does AI help with writing—and when does it take over?

Stay with the learner’s idea

Imagine a hint asking: “What is one thing students can do more easily when a class is online?” The learner still has to choose a benefit and put it into words. They might decide to write about traveling, fitting study around work or access to a course.

Compare that with supplying: “Online classes allow students to balance their studies with other commitments.” That may be a useful sentence, but the tool has selected the argument and expressed it. The two responses create different writing tasks.

Make the next decision small enough to attempt

In PrepTalk’s forum-reply activity, a learner writes a reason before writing its example. This lets the support address a specific problem. Is there a reason? Does it support the learner’s position? Does the example illustrate that reason?

Suppose the reason is that online classes remove a long journey. “Many students prefer studying online” repeats a preference. An example about a student who lives far from campus would make the travel argument more concrete. A hint can point to that missing connection without inventing the student’s situation.

Research on second-language production provides one reason to keep the learner composing. Swain and Lapkin reported that producing language can help learners notice linguistic problems and modify their output. Preserving opportunities to make those decisions is our design rationale; their study did not test AI assistance (Swain & Lapkin, 1995).

Useful language still leaves work to do

PrepTalk does supply expressions such as “One reason is” and “For instance”. They help learners start a particular kind of contribution. The learner supplies the claim and the detail that follows.

There is still a judgment to make about how much help to provide. A sentence starter, a question and a completed model sentence offer different amounts of support. We need to examine what learners do with each, rather than assuming every kind of assistance preserves the same amount of authorship.

Read the finished text with its history in mind

Accepted contributions collect in the notepad. At the end, the learner can edit them together. That makes the relationship between an early contribution and the final text visible during the activity.

It does not prove that the learner could write an equally effective reply without help. That is a separate question, and one reason the research needs to look beyond completion.
