<h4>What makes a good hint?</h4>
<p>It depends on the type of problem you ran into. For stupid errors --
an arithmetic error or similar -- simply letting the student you'll be
helping to check their signs is sufficient.</p>
<p>For deeper errors of understanding, the best hints allow students to
discover a contradiction in how they are thinking about the
problem. An example that clearly demonstrates inconsistency or
<a href="http://en.wikipedia.org/wiki/Cognitive_dissonance" target="_blank"> cognitive dissonace </a>
is ideal, although in most cases, not possible.</p>
<p>
Good hints either:
<ul>
<li> Point out the specific misunderstanding your classmate might have </li>
<li> Point to concepts or theories where your classmates might have a
misunderstanding </li>
<li> Show simpler, analogous examples. </li>
<li> Provide references to relevant parts of the text </li>
</ul>
</p>
<p>Still, remember even a crude hint -- virtually anything short of
giving away the answer -- is better than no hint.</p>
