Eigenschaften
Umfang und Funktionalität
Der Safe Exam Browser ist ein angepasster Webbrowser, der auf den Rechnern, auf denen Teilnehmer/innen Testversuche durchführen, heruntergeladen und installiert werden muss. Die Einschränkungen, die dieser Browser bietet, sind vergleichbar mit denen eines Popup-Fensters. Der Unterschied besteht jedoch darin, dass der Safe Exam Browser eine Software ist, die auf dem Client-Rechner läuft, und deshalb viel effektiver arbeiten kann. Wenn Sie einen Safe Exam Browser einsetzen, dann gilt folgendes:
- Teilnehmer/innen können einen Testversuch nur in einem Safe Exam Browser starten.
- Das Browser-Fenster ist ein Vollbild-Fenster ohne Navigationselemente.
- Das Fenster kann erst geschlossen werden, wenn der Testversuch abgeschickt wurde.
- Die Shortcuts Keys wie Win, Ctrl+Alt+Del, Alt+F4, F1, Ctrl+P, Printscreen sind deaktivert.
- Copy&Paste und andere Kontextmenüs sind deaktiviert.
- Das Wechseln zu anderen Anwendungen ist deaktiviert.
- Das Surfen zu anderen Websites ist verboten.
- Es können zusätzliche Webseiten, Ressourcen und Applikationen vom Teacher freigeschaltet werden.
- Rechtschreibeprüfung ist gemäss Voreinstellung deaktiviert.

Allowed browser exam keys - Insert allowed Browser Exam Keys for versions of Safe Exam Browser that are permitted to access this quiz. If no keys are entered, then Moodle does not check Browser Exam Keys. Can only be set if "Require the use of Safe Exam Browser" is set to "Yes – Upload my own config" or "Yes – Use SEB client config". When using the option "Yes – Upload my own config", you have to re-download the configuration file from the attempt quiz page (using the button "Download Configuration") and use that file to calculate the Browser Exam Key in each SEB version you want to allow for this quiz. These re-calculated Browser Exam Keys you need to copy-paste into the "Allowed browser exam keys" field (each key on a new line). The reason for this is that Moodle changes the Start URL setting value and formatting of the configuration file you initially uploaded to the quiz settings, therefore the Browser Exam Key changes. This doesn't apply when using the option "Yes – Use SEB client config". Remember that using the Config Key, which Moodle automatically calculates, is much easier.
Welche Einstellung überwiegt
If there's two different values for e.g. "Enable quitting of SEB" in the template and the user interface, the value in the user interfaces is taken more into consideration. That means that a value not set/left empty does reset a value in the template.
