  variable_set('dpistudy_score_screen', '<p>Your Digital Propensity Index score is <strong>@score</strong>. A score of 34 would represent the far extreme Digital Immigrant as opposed to the other extreme of 170 for a pure Digital Native.</p>

<p>According to <a href="http://www.marcprensky.com/">Marc Prensky</a>, Digital Natives are more likely to be used to receiving information quickly, like to parallel process and multi-task, prefer their graphics before text, and prefer random access like hypertext you see on websites. They function best when networked, thrive on instant gratification and rewards, and like games.</p>

<p>Digital Immigrants commonly did not grow up with digital media. They prefer linear, step-by-step tasks, perform best when doing one thing at a time, and are used to receiving information slowly. A comparison of Digital Natives and Digital Immigrants is as follows:</p>

<table border="1">
<tr><th>Digital Immigrants</th><th>Digital Natives</th></tr>

<ul>
<li>Merely adopted aspects of new technologies</li>
<li>Turn to the Internet second rather than first</li>

<li>Bring people physically to view websites</li>
<li>Call to confirm email receipt</li>
<li>Used to receiving information slow</li>
<li>Prefer text before graphics</li>
