Guided annotating #371

Currently the possible types of content for annotations are free text and structured annotations. Additionally instructors (anyone with admin rights in the annotation tool) should be able to create questionnaires. These questionnaires should consist of multiple questions followed by a free text, single choice or multiple choice answer. Students should only be able to use the content type questionnaire when a questionnaire has been defined by an instructor.

If I get it right, with adding questionnaires the annotation tool would change its main goal from analyzing video material to enriching educational videos with self-tests and quizzes. And I do not know, if we should go this way. In my opinion there are existing tools which allow questionnaires that are better suited for such usecases.

Anyhow, I think there is some thorough specification needed. For example (to only mention a few):

What hapens with answers of students to these questions? Do they get saved as normal annotations but only "shared with administrator"?
Should the teacher be able to indicate correct/wrong answers?
Does the student receive a feedback how he performed? If yes, when?

Thank you for your feedback. The questionnaires are supposed to be a help when analyzing that can be answered multiple times within a video. As the questionnaire would be a type of content. As for your questions:

The students answers should be saved as normal annotations. Therefore the sharing options are tied to the track.
Indicating correct / wrong answers and giving feedback is not currently planned. Although, while not ideal, it could happen in the comments to the annotation.

Ok. But still a lot of questions remain and I'd like to repeat my suggestion to write a thorough specification. For example: How does an admin set up a questionnaire? How does a student answer these questionnaires? Is there an additional button? Or does an admin insert a questionnaire at a specific point in time and when reached, does the video stop and a modal gets opened showing the questions? ...

We talked about this issue and the term questionnaires was quite misleading. The goal is not to provide a questionnaire in which students have to answers questions which are then marked as right or wrong. The goal is to enable instructors to create forms to guide their students through a previously specified annotation process. For this purpose instructors shall have the option to define an annotating form that can contain multiple instruction and annotation combination.
