- No need to say right or wrong. This will be done graphically
- At the moment the student finds out they've made a mistake, they are focused on why is that wrong? not where would that be right? So ask yourself what misconception could the student be carrying, in order to have thought that was the right answer? Then think of the one thing that could make it impossible to carry that misconception in future. Tell them that, using keywords.
- The feedback screen displays the stem, the chosen response and the feedback so the student can view them in context. A couple of sentences is probably the maximum length for feedback to be effective.
