Motivation
Videos for Teaching
learning-videos are more and more used in
classrooms and lecture theaters
only consuming character
the maxim
”
TV is easy and book is hard“ (Salmon,
1984) described that multimedia is over estimated in
concerns of learning success
the learning success differs in no way compared to
learning with a book
due to MOOCS (Massive Open Online Courses)
videos are giving a kind of comeback

Motivation
Why Interactions?
missing interactions are leading to passive learners
and to a much more surficial work
avoid that learners become tired or annoyed
increase the attention and the contribution
feedback for teachers:
Is it possible for the learners to follow the content?
Is the speed appropriate?

Implementation of a Prototype
Interactions
interactions are grouped to interaction-methods
each interaction-method has a type:
1. automatically invoked methods of interaction
2. lecturer-started methods of interaction
3. attendee-invoked methods of interactions
4. planed methods of interaction start their
interactions at predefined positions

Implementation of a Prototype
Global Analysis
analysis of the attention with a computed
attention-level
consists of the reaction-time of the interactions and
the values set by the attendee
maxim: if the attendee reacts slower the
attention-level decreases

General Feedback
content-related questions are the most valuable ones
general questions are sometimes confusing
the welcome-interaction improves this issue
many different possibilities of analysis are very
interesting

Conclusion and Outlook
Conclusion and Outlook
interactions during videos help to support the
attention and contribution
content-related multiple-choice questions
detailed possibilities of analysis
further research is required to analyze the impacts of
the interactions on learning and teaching
