As part of the lecture you are supposed to perform WoZ experiments. Here
is a small introduction to this issue.
In these WoZ experiments you should not just think about today's
lecture topic at a theortic level. Rather, the aim is that you
practically touch it, i.e., that you derive a practical feeling about
what we are talking about. To do so, we distribute exercises and some
additional material about different topics, such as mathematics,
geography, biology etc. However, feel free to invent your own
exercises!
The WoZ is performed in groups of three people whose roles are: the System,
the Learner, and the Observer. The experiment should work as follow:
- The complete group thinks about today's lecture topic XXX: How can the system
support XXX? What does it need? In which form? (Typically, we give you some
more advice in the lecture on what to focus in the WoZ) That is, you
hypothesize how the system could/should work wrt. XXX.
- The System and the Observer become more concrete about these
questions wrt. the given exercise. The Learner should not see the
exercise material beforehand!
- You start the main WoZ: The System and The Learner should communicate in
written form (we suggest to use small cards, that are exchanged between
the System and the Learner). The Observer observes the two and
may makes some minutes about their communication.
- Afterwards, the whole group analyses the experiment and compares it with
the initial hypotheses: What were your findings by the experiments?
Were your initial hypotheses correct and sufficient? What was not correct?
What was missing? How did these problems turn out during the experiment?
etc.
Afterwards, you should write a brief report about you WoZ, which should reflect
the three phases: hypothesizing, experiment process, and experiment analysis +
comparison with initial hypotheses. That is, your report should first
describe your initial hypotheses. Then, it should describe the process of
the experiment (e.g., by giving some relevant communication between The
System and The Learner, which (the communication) should be written anyway,
see above). Finally, the report should give findings of the experiment
(not just some theoretical ideas, but the real findings of the experiment
and how you found out by the experiment) and a comparison with the initial
hypotheses. The reports should exceed 2 pages.
