A pre/post-test assessment was conducted in order to evaluate the participants’ knowledge before and after
viewing the educational multimedia clips. In the beginning of the testing session, each participant was provided with
written and verbal instructions about the purpose of the study and the structure of the testing session. After that the
participants completed a demographic questionnaire and the pre-test questionnaire. The pre-test questionnaire was
presented in a pen and paper format and consisted of six single-choice closed questions (one for each of the six
educational clips). As the questions were highly specific to the clips, a non-response type choice, i.e., “I don’t
know”, was also included in order to minimise the number of correct answer guesses. Before starting the actual
testing, the participants were provided with a brief training to familiarise them with the testing procedure.
