An alternative has to be usable

A choice between two approaches can disappear without either option being formally withdrawn.

Consider a constructed teaching example. A class can present its work as a short video or a written account. Both formats remain on the task sheet. The school’s available devices cannot edit the video, however, and no time is provided to learn the software. The alternative exists in the instructions while becoming difficult to use.

That does not establish that video is the better format, or that every learner should choose it. It changes the question asked of the choice. What would someone need in order to take either route, and which of those conditions does the task actually provide?

The public AE introduction asks how people become able to act and how their activity changes later possibilities. Applied here, it keeps permission, access, knowledge and time distinct. Giving permission answers one question. Providing a workable route answers others.

A useful inquiry could compare the written options with what learners can do during the allocated period. It could ask what support is requested, whether help arrives, and whether selecting a format brings extra work outside the lesson. These are proposed observations within the example, not findings from an EdgeLab study.

An ordinary resource shortage may explain the difficulty. So may a justified decision to prioritise writing, where the learning goal concerns a written argument. Those explanations should be assessed before expanding the case into a general criticism of institutional choice. The task’s purpose, available resources and learners’ experience supply different pieces of evidence.

EdgeLab’s research programme treats a completed output, a new capacity and a worthwhile outcome as different findings. A finished written account cannot by itself show that both options were usable. Nor does making video production possible settle its educational value.

The next version of the task need not offer more formats. It might explain why one is appropriate, provide the missing support, or remove a nominal choice that cannot be honoured. The responsibility is to make the stated possibilities correspond to a route someone can actually take.
