My previous problem proposition (as a reminder: “What
is the impact for both the community and the company of community
management when advertising an IT product on Twitter?) is in my
opinion not a suitable problem to set an experiment. This issue needs
to be researched in an everyday life context and not in an
environment I would design and set up myself. Of course this is
debatable, but to gain some time I’ll examine another problem. This
new problem is actually related to a situation I experienced during
my studies:
How
does the usage of videoconferencing affect the process of learning of
master’s students in comparison with a physical classroom in the
context of academic lectures?
First
here is a short justification for the choices made. In order to have
a bigger influence some Universities tend to merge together and thus
can have several campuses with similar lectures being given
simultaneously in different locations (e.g. the University of Eastern
Finland with 3 campuses in a 150km radius), videoconferencing is a
good way to merge these distant lectures into one. I would study
master students as they still have academic lectures but are rather
autonomous, which will probably lead to a more nuanced outcome than
with bachelor students.
To
study this problem I propose an experiment. This experiment would
last for a whole semester in order to cope with the possibility of a
significant adaptation time from the students. It would involve 3
groups of approximately 20 students (a normal sized class), speaking
the same language (in order not to add any problems related to the
language barrier or cultural adaptation to the equation) and from
similar backgrounds.
I
would study 3 different situations:
Classical
lecture: The teacher gives the lecture in the classroom where the
first group of students is situated.
Video
transmitted lecture: The classical lectures would be transmitted live
to the second group of students in a regular classroom situated
elsewhere with a video and audio feedback to the primary lecture
theoretically allowing conversation between the two groups.
Totally
decentralized lecture: a second teacher would broadcast live lectures
from his office with the same content to the 3rd
group of students through a software such as Adobe Connect. The 3rd
group of students can be wherever they want provided that they have
access to a computer and an internet connection. The lecture would be
both audio and video with the possibility to display and edit slides
live, the feedback from students could be only written on a common
chatroom.
Throughout
the semester a researcher would be present in both classrooms and in
the 2nd
teacher’s office and would keep a journal about the way they
perceive the reactions from the participants and keep record of the
unavoidable technical incidents. At the end of each lecture, each
student would have a really short questionnaire about their feeling
about the lecture. At the end of the semester each researcher would
conduct individual semi-structured interviews with the students from
their group. Some quantitative data about the success rate of the
different groups of students on a common final exam could also be
used but with caution as it is in my opinion more relevant to focus
on the process itself than on the raw outcome in order to improve it.
The semi structured interview would focus on the way students handled
their difficulties, the quality of interactions within the class, and
their opinion on the medium used.
This
should give some quality data to study to answer the problem, but I
would also include the quality of students’ feedback in their
assessment for the lecture in order to motivate them to give valuable
outcome.
To
finish, I have to admit that my experiment isn’t perfect. Some
ethical aspects of it could really be discussed as the very
foundations of this experiment is to study the differences between
three mediums of teaching and thus consider de facto that they don’t
give the same chances to students. Also acquiring some data on
students’ performances on exams is could be criticized, as well as
taking their participation into account in their final assessment.
In order to appreciate the outcome of this experiment it would be necessary to find some previous studies on the subject. I didn't took the time to research further on the subject, but some case studies about the usage of video conferencing for teaching an learning are available here : http://www.icbl.hw.ac.uk/ltdi/vcstudies/vcstudies-all.pdf (Videoconferencing for teaching and learning, 1999). It's important to note that the technics have greatly evolved since then and thus, these case studies are probably more relevant to compare with the study findings about the second group of students than the third one who would be using a more complex technology. It could also be interesting to compare the results between the second and the third groups of students in the light of Q. Zhang and C. P. Fulford's article about the effects of having a one way video connection between the students and teachers compared to a two way video connection (Two-way and one-way video: when is 'no difference' significant in distance education? , 1996), even though, once again, due to the age of the study, the setup in their experiment was probably quite archaic in comparison with what's available today.
