Implementation

By default, the tan-linked online procedure is carried out. Respondents receive a one-to-one randomly generated TAN per survey by e-mail, which is embedded in a URL. In the case of several surveys being conducted at the same time, respondents receive one e-mail with several survey links. This procedure ensures that respondents can only participate in the survey once; participation by unauthorized third parties is not possible. The vote is not stored in connection with the TAN or e-mail address.

The surveys can also be reached via the OVGU E-Learning portal (moodle) in the evaluation period, if it is used by the lecturers for course administration. This ist not mandatory. The plug-in view in the e-learning portal uses the e-mail address (of both lecturers and students) as identifier. There is no direct comparison with the data in Moodle (e.g. course enrollment). Moodle serves only as a viewing medium, not as an interface.
