Before enrolling a child in an online course, try a short instruction in the form the lessons will use. Can the child locate the right button, switch between the task and the explanation, and understand what to do after an error? The difficulty may come from the interface or wording rather than the subject. Keep the trial short and observe where help is needed, without turning it into an exam or a judgement of ability.
The school-course catalogue Z-toy can help you find options to discuss with providers. Ask whether a sample task shows the real platform and whether instructions are available as text as well as speech. Clarify how the teacher responds when a pupil gets stuck navigating the tool. A course that matches a child’s interests still needs a workable way to receive instructions, ask a question and try again.
