However, in order to call them, <b>they first have to be added to the SQL data base</b> for the course. The lecturer can do this with help of his administration menu. </p> <p> As soon, as this is done (we have provided three exercise html-files called <i>E-1-002-A-1.html</i>, <i>E-1-002-A-2.html</i> and <i>E-1-002-A-3.html</i> in the folder <i>contents</i> and, to simplify their installation in the admin menu, also a file containing their names in <i>contents/lecturer/exercise.dat</i>) you may try to click at them. In case you have deactivated the data base by setting the variable $db_active="0" you cannot access exercises and thus you will not see the following link to the exercise. </p> <p>Click on one of the following</p> <p>[EXERCISE=E-1-002-A-1.html TEXT=A simple exercise]</p> <p>[EXERCISE=E-1-002-A-2.html TEXT=An exercise with follow-up]</p> <p>and the exercise will be displayed in a separate window. In the html-code of the present page you find the exercise reference in another electure-command named "EXERCISE", indictating the filename of the exercise.</p> <p>The exercise file itself (e.g. <i>E-1-000-A-1.html</i>) contains both, the exercise text and an arbitrary number of answers. It is up to the pedagocial talent of the lecturer, to utilize this structure. One may use multiple choice answers, stepwise solutions, answers that contain further exercises etc.</p> <p>To optimize the organisation of the files we suggest, that the filenames of the exercise files contain a unique string (in our sample course the string "-A-").</p> </body> </html>
