        <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>
