HCD.23:4.2 - Explain a connection and have another person use it

Ask the first participant to connect the decisive input to the proposed action: which condition applies, why the chosen rule fits, and what follows. The listener locates the step they accept or cannot reconstruct. They can paraphrase the connection, apply it to a small variation or identify what evidence would defeat it. A generic request to elaborate is useful only if it helps recover that missing step.

Reverse the contribution where both people need practice. One participant may explain the model choice and another challenge the measurement basis, then each handles the other’s kind of question in a subsequent attempt. If the task requires active observation, a learner can predict, point to a discrepancy and ask for a pause while another operates the equipment. The relevant reasoning action matters more than a universal turn format.

Keep the disagreement about grounds. Ask whether both explanations concern the same observation, conditions and required result. If they differ, align those inputs before choosing. If the subject rule is disputed, use a qualified source or prepared provider; voting cannot supply it. A useful exchange can end with a precise unresolved question and a supported partial result.
