Motivation

Videos for Teaching

learning-videos are more and more used inclassrooms and lecture theaters

only consuming character

the maxim ”TV is easy and book is hard“ (Salmon,1984) described that multimedia is over estimated inconcerns of learning success

the learning success differs in no way compared tolearning with a book

due to MOOCS (Massive Open Online Courses)videos are giving a kind of comeback


5

Motivation

Why Interactions?

missing interactions are leading to passive learnersand 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?...

Interactions

interactions are grouped to interaction-methods

each interaction-method has a type:

1. automatically invoked methods of interaction2. lecturer-started methods of interaction3. attendee-invoked methods of interactions4. planed methods of interaction start their

interactions at predefined positions


10


Interaction-methods of Type 1

Welcome: explains the usage of the interactions tothe attendees at the beginning of an event

Simple Questions: Asks some simple questions tostudents automatically.

Solve Captcha: Displays a simple captcha tostudents to solve.


11


Interaction-method of Type 2

Ask Students: The teacher can ask a question tostudents and read their answers.


12


Interaction-methods of Type 3

Ask Teacher: Students can ask a question to theteacher and read his answer.

Set Attention: Students can set their current level ofattention.

Report a Technical Problem: Students are able toreport a technical problem to the teacher.


13


Interaction-method of Type 4

Planed Multiple-Choice Questions: Students getmultiple-choice questions at predefined positions.

Planed Multiple-Choice Questions

Global Analysis

analysis of the joined-timespans


19


Global Analysis

analysis of the attention with a computedattention-level

consists of the reaction-time of the interactions andthe values set by the attendee

maxim: if the attendee reacts slower theattention-level decreases

First Evaluation

Overview

used at “Learning in the Net: From possible andfeasible things” at the Karl-Franzens University ofGraz8 videos, each has a length of approximately 10 min.exemplary occurrence of the interactions:

First Evaluation

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 veryinteresting


25

Conclusion and Outlook

Conclusion and Outlook

interactions during videos help to support theattention and contribution

content-related multiple-choice questions

detailed possibilities of analysis

further research is required to analyze the impacts ofthe interactions on learning and teaching
