Introduction

<P>
With institutions putting an ever-increasing emphasis on
computer-assisted learning and computer-mediated communication (CMC),
place and space for face to face is in danger of being ousted from the
timetable. It is increasingly argued that, to survive, all universities
will have to cross the e-line into internationally competitive, IT-
based online learning (eg. Oblinger, 1999). Such a move implies change
in the process of learning and in the roles played by both staff and
students within universities and other HE institutions.

<P>
Rosenberg (1999) suggests that the interactive and virtual nature of
online education is transforming the traditional role of the teacher
into that of information and knowledge facilitator and technical
integrator. Riel (1995) has likewise argued that the technology leads
to a shift in role for the tutor, from being controller of information
to intellectual leader. The tutors task becomes that of structuring
challenging conversations among a community of learners rather than
channelling expertise and knowledge to the student. These arguments
seem almost to imply that there is something inherent in the medium
which will bring about a transformation in the way in which learners
learn and teachers teach.

<P>
However, against this it can be argued that the use of computers does
not in itself assure a rich, interactive exchange of ideas. On the
contrary, CMC can be passive, didactic, competitive...and other
directed. (McCabe, 1998). Conversely, the lecture theatre does not have
to be a passive environment. Although lectures have not traditionally
been very interactive there is intrinsically little to stop them being
so (Race & Brown, 1998). It may therefore be argued that successful
learning outcomes have as much to do with the individual pedagogic
style, approach and assumptions of tutors as the affordances of the
teaching/learning medium (Light, Nesbitt, Light, & White, in press).

<P>
Many of the key social skills needed for nurturing online collaboration
are not specific to the CMC environment. Rather they are the skills
needed by any tutor, facilitator...involved in any peer learning
situation (Kaye ) . Some tutors will be better than others in designing
and implementing group learning experiences. Harasim Hiltz, Teles and
Turoff (1995) suggests that those who find themselves comfortable with
the basic premises of peer learning and small group work (in the face
to face situation) will adapt well to the CMC environment.

<P>
Provision of CMC course support resources does not necessarily equate
with uptake. Typically the tutor not only has to make the CMC resources
available to students but also has to sell their usefulness and
potential before learners will take advantage of them. Crook (1997)
reports on students use of hypertext lecture notes, which were
supported by a bulletin board and email facility designed to facilitate
interaction and questioning in relation to the notes. He found that
although the students read the notes and regarded them as a valuable
resource, none used the bulletin board for discussion and few used the
email launcher. Also, rather than navigating the hypertext notes, most
students printed out a hard copy of lecture notes to take away for
private study later.

<P>
These observations suggest that interactivity rarely occurs
spontaneously, even in a well supported CMC environment. Rather, it
usually requires a facilitator to engineer and maintain it. This
facilitator is usually the tutor, whose task is to create a context
within which there can be shared goals, interests and commitments
(Kaye, ). Inevitably, the direct engagement of tutors is likely to
influence the kind of discussion that takes place. Even where tutors
are wholly absent from the CMC discussion, the way in which they have
framed the activity may be a significant factor influencing the course
of discussion. Light, Nesbitt, Light & Burns (2000) describe a case in
which the tutor was absent from CMC-based discussions taking place in
parallel groups of students. The style of contribution was relaxed and
linguistically varied. However, there were also instances of flaming,
when selected participants were personally targeted with offensive
messages. Such instances can have a very disruptive effect on the whole
group, and prejudice the likelihood of useful learning outcomes.

<P>
The relationship between the CMC resource and other available learning
resources is important, as is the relation of all learning resources to
the curriculum and assessment of the course. The CMC element has to be
embedded in the whole course rather than being merely an add-on. A
structure needs to be in place which, in Gilberts (1995) words,
successfully initiates connections among people who want to learn,
people who want to teach, and the world of information and ideas.

<P>

<P>

<P>
Skywriting

<P>
The study reported here shows how one tutor teaching psychology
undergraduate students in a campus-based university set about such a
task and reviews the outcomes from both the tutors and the students
perspective. Earlier research (Light, Colbourn & Light, 1997; Light &
Light, 1999) with the same cohort of students meant that the
researchers had data from students who had been in their first year and
were now presently in their third, thus providing a relatively rich
context for the study.

<P>
See: 
<a  HREF="http://www.cogsci.soton.ac.uk/~harnad/Hypermail/">
http://www.cogsci.soton.ac.uk/~harnad/Hypermail/ </A>

<P>
The tutor in this study developed a form of CMC that he called
skywriting (Harnad 1990, 1995, 1999). He used it as an adjunct to all
of his courses, including the three courses described in this paper.
The three courses in question, one in the first year and two in the
third year, ran for one semester each and were taught by the same
tutor. The first year course was a lecture- and tutorial-based course
for the whole cohort of students. The two third year courses took place
in successive semesters. The first semester course was a seminar- based
optional course, while the second semester course was a lecture-based
course for the whole cohort. Skywriting was an integral part of each
course; contributions being required but not directly assessed.

<P>
Skywriting involved all messages going to a course email list that
included all students and the tutor. As well as receiving all messages
directly, participants could access them via the Internet, where the
tutor archived them using Hypermail at regular intervals. Accessed in
this way, the messages could be sorted by author, date or (most
usefully) thread. Students were encouraged to use a quote/comment
procedure. To do this the students would save the text into a text file
in a word processor and then select the lines of text they were going
to comment on, using > quote/indents. URLs contained in messages became
active hypertext links.

<P>
In guiding the students as to the style and level of contributions
expected, the tutor used the analogy of a bright kid-sibling. Thus
kid-sib was that kind of communication that would be required to
satisy: that super-intelligent younger sibling you [are] meant to have
in mind ...brilliant, fervently interested in finding out what youve
learnt, but COMPLETELY ignorant about it, and with no patience at all
when what you are saying doesnt make sense. Apart from academic
postings, skywriting was also used to deliver administrative notices,
technical tips, advice for exams and so on.

<P>

<P>

<P>
A first year lecture course

<P>
<a  HREF="http://www.cogsci.soton.ac.uk/~harnad/Hypermail/Explaining.Mind96/">
http://www.cogsci.soton.ac.uk/~harnad/Hypermail/Explaining.Mind96/ </A>

<P>
The study was conducted at a UK campus-based university. Almost all
students were full time, residential students. Explaining the Mind was
a lecture course taken by some 80 first year Psychology Honours
students (plus 50 other students) in 1996. A full account of the use
made of skywriting on this course is available in Light & Light (1999);
a briefer account will be given here to contextualise the account of
the same students use of skywriting in two of their third year
courses.

<P>
Skywriting was offered as a supplement to the traditional structure of
the course, namely two lectures a week and a fortnightly tutorial in
groups of about ten. Students were encouraged to use skywriting to ask
questions and to enter into debate with the tutor and fellow students
about issues arising in the lectures or tutorials.

<P>
Over three quarters of the students were straight from school, the
remainder being mature students, mostly in their thirties. Three
quarters were female. A questionnaire measure of attitudes to, and
prior experience with, computers (based on Davis & Cole, 1993) was
administered to all students on entry to the Psychology programme.
There was an overall gender difference in self-reported experience
(favouring males), but attitudes to computers were positive in both
groups. A complete round of tutorials was observed and tape-recorded
from which a measure of the frequency of unsolicited verbal
contributions by students was obtained. Male students, though a
minority, made on average more than twice as many such contributions as
female students.

<P>
Turning to the frequency with which the students used the skywriting
facility (measured at the halfway point in the twelve week course),
only about 40% of the students made multiple contributions in this
medium (range 2-12 messages). The female students made just as much use
of skywriting as the males, and neither attitude to computers nor the
self-reported experience with computers was predictive of extent of use
of skywriting.

<P>
A measure of learning style, the Revised Approaches to Study Inventory
(Tait & Entwhistle, 1996) was administered to a subset of twenty-four
students, twelve of whom had contributed actively to the skywriting and
twelve who had not. The active skywriters scored significantly higher
on the index of deep approaches to study. Frequency of skywriting
contributions also showed a modest but significant positive correlation
with assessment outcomes on the course, whereas frequency of face to
face tutorial contributions did not.

<P>
The skywriting contributions themselves tended to be short (c. 100
words) and usually took the form of a question addressed to the course
tutor. Almost all were replied to, the result being that almost half
the messages on the list were from the tutor. Few student contributions
expressed opinions, and few drew any response from fellow students.

<P>
Interviews with 19 students (11 active contributors and 8 not)
highlighted the advantages of skywriting for those students too slow
off the mark or too reserved to make much input to the group
tutorials.  At the same time, the students were very conscious of their
peers as audience when using skywriting. Whereas their messages were
for the most part questions directed at the tutor, they were clearly
concerned that any silly mistakes they might make, or any withering
response from the tutor, might show them up in front of their peers.
Moreover, they were using other students messages as a basis for social
comparison, to gauge how well they themselves were doing relative to
their peers.

<P>
Though the balance of student opinion at the end of the course was
quite favourable to skywriting, the overwhelming majority preferred
face-to-face tutorials. The immediacy of response and the continuity of
discussion figured prominently amongst the perceived advantages of
traditional tutorials.

<P>
Reflecting back on this first year lecture course the tutor said that
he had introduced skywriting very much as an enthusiast. Use of online
discussion was not common amongst other tutors in the department, and
certainly not amongst the students (Light, Colbourn & Light 1997). The
tutor recalled their initial resistance..about computers themselves. He
almost had to blackmail them into posting at least one message...and
then a second. ...it was a bit like pulling teeth.

<P>
The breakthrough came when he put up a pre-seen exam of seventy-six
questions for them to answer as practice on skywriting. This seemed to
break the ice. However, it made him realise that if all of the students
became very active it could rapidly become overwhelming for him as a
tutor. During the course semester the tutor did indeed make a lot of
postings, one hundred and sixty-six in total.

<P>
To make economic sense of his online time answering questions, he
thought it a good idea to build a data resource. Thus he developed
Frequently Asked Question (FAQ) files which could be archived through
hypermail link to other skywriting files: so they loop through one
anothers material. Thus students could be re-directed to a file which
already contained the answer to their question. This meant that when
answering a question for the first time it was worth while to
grandstand a little bit....[otherwise] I wouldnt have taken the trouble
to answer one student quite that extensively.

<P>
Certainly the students made good use of the tutors postings. Everyone
read them, including those who made no contributions of their own.
However the tutor regretted that he was perceived as the main
interlocutor. He wanted skywriting to be more interactive, with
student-to-student as well as student-to-tutor exchanges. He hoped this
would happen in the later seminar options, where there were relatively
few students and where discussion arising from weekly meetings could
carry over into skywriting.

<P>
The students involved on this course were new to university study and
new to skywriting. The tutor was also new to using skywriting in this
way with students. The opportunity to return to this same group of
students being taught by the same tutor two years later thus afforded a
chance to look at how experience impacts on both students and tutors
use of this type of CMC resource.

<P>

<P>
A third year seminar course

<P>
<a  HREF="http://www.cogsci.soton.ac.uk/~harnad/Hypermail/Foundations.Cognition/">
http://www.cogsci.soton.ac.uk/~harnad/Hypermail/Foundations.Cognition/ </A>

<P>
Fourteen students enrolled for a final year seminar course entitled
Socio-biology and cognition. Students met weekly for seminars and took
turns in presenting to the group a synopsis of a book or articles they
had read in the preceding week. Following this, the same students then
posted a summary version of their presentation, taking account of the
in the class discussion, to the course email list. Online, everyone was
invited to comment on it using the quote/comment procedure. The tutor
also encouraged the students, as in the first year, to post him if
something came up during the tutorial session and we dont get a chance
to cover it to your satisfaction.

<P>
As with the first study the researchers used a multi-method approach to
collect data. They attended three of the seminars. These were each one
hour and forty minutes long. They were introduced to the students by
the tutor and the students were apprised of the nature of the research
project. The researchers names were added to the skywriting course list
so they had instant access to all online contributions. The three
seminars were audio taped and observation notes were taken..

<P>
At the end of the course the students completed a standard course
evaluation questionnaire for the tutor. They were asked to evaluate
course content, course organisation and tutor contribution on a scale
of 15 (strongly agree to strongly disagree). The anonymous responses
were made available to the researchers by the tutor. The researchers
then invited students to individual interviews of between twenty to
thirty minutes, twelve of the fourteen students accepted this
invitation. They were asked to look back to their first year use of
skywriting and to compare it with their most recent use. All interviews
were transcribed and analysed qualitatively.

<P>
Initial analysis of the data from the three seminars attended, along
with the accompanying skywriting contributions, showed that not all the
students contributed to seminar discussions (five making no verbal
contribution at all). However, all the students did contribute to
skywriting, although only half of them had done so on the year one
course. As one student reflected it didnt seem to be like a duty or a
threat, something you must do. Instead it just comes out [that] I
should do it.

<P>
The students not only felt a commitment to their peers to make
contributions but they also felt their contributions should be good: I
always make sure its a decent message, and that Ive thought about it
and planned it out. The use of skywriting seemed to reinforce
relationships: I know people better than in my other seminar class
(where skywriting was not used). It created: a sense of community
within which they could:get the idea of what everyone else is
thinking.  They also appreciated the practical efficiency gains of
sharing the reading load, which they all felt was heavy.

<P>
The students contributions show an effective use of skywriting both as
a tool for summarising tutorial discussions and as a tool for critique.
A somewhat less formal tone is apparent between student and tutor, for
example: Sorry, Ive had a delay getting back to you via e-mail but
right now I have been immersed in lots of reading and very little
analysing. Luckily, your points left me doing an awful lot of further
thinking, which is a great help! In what follows the same student
offers opinions, starts sentences with, for example: I agree, I admit
Im still not sure Why should it matter?, and ends with: Let me get back
to you on that one!.

<P>
Many of the skywriting ideas were picked up on in the face to face
seminar sessions and vice versa. Skywriting, as one student put it,
gets more of a debate going amongst people. This was contrasted with
other seminar courses where students aimed to score lots of marks
because you said what the lecturer wants you to say. However it had
taken the whole course for people to work out how best to use
skywriting.

<P>
The students saw the point of the kid-sib analogy: If you cant explain
it in simple terms you probably dont understand it. When writing
messages only three of the students said they primarily directed them
to the tutor; seven others said they were intended for everyone, while
two students relied equivocally. Altogether the 14 students contributed
74 messages and the tutor contributed 33. This contrasts with the first
year, where tutor contributed as many messages as the students, but
still represents a high level of participation by the tutor. The
students were appreciation of his active role: [he] keeps us on the
right lines because I think sometimes we do go off on a tangent'; [he]
guides us towards the right frame of mind. However, this did not mean
that the tutor was chairing the discussion: he gives input but he
doesnt really structure the discussions. In contrast, in seminar
sessions the tutor definitely took a structuring role in discussion.

<P>
All the students found the skywriting postings useful for exam revision
and accessed them from the archive. One student would regularly
download the messages onto a disk then take it home, sift through it
and delete all the bits that are rubbish and keep all the good bits and
then just print them out and revise from them adding my own comments.
Of the twelve students interviewed, nine were owned their own
computers, though only three of these were networked.

<P>
In contrast with the first year, peer contributions came to be regarded
by the students as a valuable resource for learning. When youve read an
article youve [only] got your own understanding of it. But if you go on
the skywriting and read loads of other peoples commentaries it puts
things together. The fact that its all grouped into different
categories [lets] you see where the course is going and where you are
going in your reasoning. However, there was still some irritation about
contributions which took them down the wrong road, as this was a waste
of time.

<P>
Compared to the first year, there was less concern about the public
nature of the system: if you get things wrong you get things wrong. One
student who was initially worried about everyone reading her comments
said at the end: I think thats a good thing because instead of writing
a paragraph of useless drivel you actually go away and research. All
agreed that working within a small group: you feel more confident; In
the first year [there were] so many more people, but with a seminar you
do know the people in the group so if you cock it up or say something
really stupid nobody really minds.

<P>
However the social comparison aspect of skywriting was still
significant for the students. One commented that other peoples errors
gave him: confidence that not everybody else is completely
understanding everything. The students were reticent: to criticise
somebody else when skywriting. This contrasts with the seminars: In
class you can back down, you can say fair enough or whatever.

<P>
The third year students were also much less concerned than they had
been two years earlier about being shown up by the tutors response to
their messages. In part, they thought that this was because the tutor
had changed his style of response. One student suggested that the tutor
had: toned it down a lot in the first year he used to say no, thats
completely wrong and youd think, oh my God! Now he says No, but or It
was a very good try, but, so its useful . Another student referred to
first year replies from the tutor as a bit of a hacksawbut [he] now
appreciates your ideas and your questions. How far this is a matter of
changing student perceptions or higher quality student contributions is
hard to judge, but the tutor certainly felt that the change was more in
the students than in his own behaviour.

<P>
The students perceived skywriting as complementary to face to face
tutorials. The latter allowed for immediate reactions and immediate
explanations while the former gave them a chance to have ideas
continually ticking over throughout the week. It seems that working
within a smaller group the students were able to evolve a way of
working that drew the best from both learning environments. The course
evaluation questionnaires gave high ratings for the course and
particularly for the tutor. The tutor later described this group as a
particularly good one, resulting from: self selection...these were the
ones who were up to it... they were all top students. Seven of the
students indeed obtained first class marks on the course.

<P>
The seminar topics chosen by the tutor were explicitly about
controversial things. He observed that: because its socio-biology of
cognition which is controversial as well [as] relatively new...it
produced several zealots people who ended up being more bullish about
socio-biology and cognition than I was. Towards the end of the course,
the tutor felt that they had succeeded in; [bringing] down a few
intellectual barriers, with students becoming actively engaged in
debate. He felt that skywriting had helped to get away from the school
ethos to something much more level [as between tutor and students].

<P>
However, this was only a matter of degree. The students still tended to
pit their arguments against the tutor rather than against their peers.
Overall, the tutor was still regarded as the expert. The students
remained more interested in his contributions, in his responses and his
ideas on the ambiguities left over from the class than in those of
their peers. Indeed, there would have been fewer readers if there had
been no tutor contributions; the tutor was the catalyst. There remained
a lurking suspicion that peer contributions were a bit suspect.
However, overall, the students were confident users of skywriting and
made good use of it for shared learning.

<P>

<P>
A third year lecture course

<P>
<a  HREF="http://www.cogsci.soton.ac.uk/~harnad/Hypermail/Debates98/">
http://www.cogsci.soton.ac.uk/~harnad/Hypermail/Debates98/ </A>

<P>
Current Debates was a compulsory lecture course taken by 80 students in
the second semester of the third year, tackling a range of contentious
issues in contemporary psychology. Skywriting was again a required,
although not assessed, part of the course. The tutors aim in using it
was: to increase student contribution rather than student querying
and:  to elicit more student-on-student comments.

<P>
To this end, the tutor decided to reformat the skywriting structure for
this course. The course itself was based around target articles and
peer commentaries from the journal Behavioral & Brain Sciences (BBS).
Thus the basic reading material consisted of ten BBS target articles
(plus peer commentaries and author-responses). This material was
accessible via the web, although hard copies were available in the
library. The students task was to quote/comment three times on a few
assigned pages out of three of the ten BBS article/commentary/response
sets.

<P>
For example, in the first assignment seven students were asked to
quote/comment on particular parts of the target article and then seven
more were asked to reply to these comments. Four other students were
asked to quote/comment on specified BBS peer commentaries, with four
more students replying. Lastly, two students were asked to
quote/comment on the BBS author-response with two further students
replying.

<P>
Thus, altogether this assignment called for 26 student contributions.
There were ten assignments in all. The smooth running of the
assignments depended on the first students getting their commentaries
in on time, as without these the following students could not do
theirs.

<P>
At the first lecture the researchers were once again introduced to the
students and were added to the online course list. By now they were
familiar faces to many of the students, having spent some time in the
department. The researchers attended four of the ten lectures, which
were very interactive in style and drew upon the skwriting
contributions. At the last lecture attendance was relatively poor,
perhaps due to impending examinations, but the forty-two students
present completed a course evaluation questionnaire. This was completed
anonymously and copies were made available to the researchers.
Thirty-seven of the 42 students also returned a (non- anonymous)
research questionnaire focusing on the use of skywriting on the
course.

<P>
The students were asked to evaluate on a numerical scale of 15
(strongly agree to strongly disagree) how well skywriting had worked
for them; for their understanding of course material, as support for
face to face learning, for exam preparation, and so on. The
questionnaire contained a tick box to indicate a willingness to
participate in individual interviews. Twelve were selected, to include
all those (5) who had taken the Socio-biology option plus seven drawn
at random from those who had not, but who had attended the first year
lecture course.

<P>
The semi-structured interviews lasted about twenty minutes each and the
students were encouraged to reflect on how their attitude to skywriting
had changed (if at all) since the first year, and the effects (if any)
of having had more experience of using it. Further issues of learning
were also explored. Again all interviews were transcribed and subjected
to qualitative analysis. Finally the tutor gave an interview of an hour
and a half in which he reflected on his use of skywriting with the
students in their first and third years. This interview was audio taped
and transcribed. The interview topics arose from observed events from
the past year. Additional sources of material were the researchers
observations and notes from course attendance and more informal
discussions with the tutor.

<P>
In the first lecture when the tutor introduced and explained the
procedure, he asked the experienced skywriters amongst them to lead
small group revision sessions on how to use quote/comment for
skywriting. This took place in the lecture theatre. However, the tutor
received feedback from some students that they were still confused, so
emailed a summary to the course list. He identified the first 26
students (alphabetically) and assigned each a specific task in relation
to the first target article, and added tips for transferring the text
from the web to the email so that it could be quote/commented on.

<P>
The next message from the tutor contained the next assignment plus
messages/reminders for those who had not yet done their first
assignments. Inevitably many were late, thus holding up the others. The
tutor afterwards described the whole procedure as grotesquely
convoluted. As the course progressed it became increasingly time
consuming to keep track of who had done what. Towards the end of the
semester, with exams nearing, the tutor had to give more reminders
about missing assignments. At one point there were 28 overdue
contributions. Tutor contributions were relatively few, though some
were long where he felt additional input was needed (the longest reply
to a student query was about two thousand words).

<P>
By monitoring the skywriting contributions closely, the tutor attempted
to spot difficulties and to sort matters out earlier rather than
later.  For example, when some were having difficulty producing
quote/comment contributions he gave them a model for doing so. He
consistently emphasised that the task was not to memorise the text but
to interact with it. Learning in any medium, he argued, starts with a
structure.  In a lecture he said: with books it is often underlining
words, while with emails you can just sit and absorb and slot in new
learning like a lego block. Not all of his students found reading off a
screen easy, however. Many commented that prolonged reading off the
screen hurt their eyes. This was certainly not a new complaint from the
students and indeed is a problem for many computer users.

<P>
The students realised from the beginning that, although they would gain
tutor approval from being actively involved in skywriting, there were
no real marks at stake. Thus the tutor sold skywriting using different
tactics. One example was when he replied to a student query in a
lecture about how to gain good exam marks. His answer was that for a
lower second they should bring in readings from the target article and
commentaries; for an upper second they should use the target articles,
commentaries and lectures and for a first they should use all of the
former sources plus skywriting.

<P>
However, the tutor also felt the need to make it clear that they
couldnt just depend on skywriting to get them through the course.
Indeed, near exam time he put out a warning that it: would be VERY
risky to try the exam having read only the skywriting as not only will
it be incomplete, but some of it may well be wrong. So use it to test
your knowledge (and to discuss if you like) but DONT use student
summaries as your primary source.

<P>
Overall student evaluation of skywriting in Current Debates was
positive. The research questionnaire showed that most students felt it
had worked well in a number of ways. It had improved understanding of
the course and worked well as a support for the face to face sessions.
In contrast to the first year, the students reported that they found
the contributions of their peers useful; 68% said that skywriting
comments on target articles were useful and 55% said the same of
student responses to student commentaries: I will be going to the
commentaries andlook what people have said about it as wellit is good
to have it as a resource.

<P>
Notably, the students reported less reliance on skywriting
contributions from their tutor than on the (much more numerous)
contributions from their peers. This may partly have been because the
tutor: said at the beginning he was trying to avoid commentingtrying to
find a happy medium. However, one student did comment that without the
tutor..I think [participation] would have dropped about 40 or 50% of
the class.

<P>
Not surprisingly, given the course structure, students reported a heavy
reliance on the web and little reliance on books/print journals: I dont
need to [rely on books] which is really good[its a] nightmare trying to
find books. Compared to their first year, these students were feeling
altogether more comfortable with CMC. As one student commented: [We]
had to get over that phobia of technologynow[we] use it a lot.

<P>
The size of the group was seen as a problem, particularly by those who
had used skywriting in the seminar option: Its so big you can't have
that interactionpeople are commenting but they are not just sending
questions to each other whereas last semester we were just sending
questions to each other all the time; A small group of eight or ten
seems like the ideal size because its enough people that you are not
going to be intimidated by.

<P>
In spite of the positive feedback the tutor felt that he had not
achieved his objective in using skywriting: because all they did was
their little, microscopic module. His feeling was the students had not
engaged thoroughly with the material, often sounding off with only 20%
of the information. He very rarely saw someone that had mastered the
material.

<P>
If he ran Current Debates again, rather than trying to force them to do
a paraphrase, of some material he would try to get them to dig their
teeth actively into the subject matter, to focus them and keep them
involved in several more iterations. What was evident was that what the
students got most out of was: being more actively involved with the
subject matter, rather than: passively listening to my answering
questions...or producing semi-authoritative summaries of which others
were sometimes mistrustful.

<P>
In this way, he believes, skywriting, can change the way they think,
not least by keeping the debate alive throughout the week: rather than
just turning up on Tuesday. By using a discipline of writing for
posterity the students might be bought to think of these things
differently: once they get an insight they get a different vantage
point on the same thing. They now listen, they can see their fellow
students [as] naive in a way that they are no longer nave.

Discussion

<P>
Most of the students we have observed in these case studies experienced
skywriting only in one first year and one final year course. A minority
experienced skywriting in three of their courses, but these taken
together still made up a small part of their studies. Some of their
other courses used email lists, but: just to say about room changes
etcetera.

<P>
The mere fact of having to participate in skywriting had evidently
helped many students overcome their fear of computers and technology.
You are made to do it and then you finally get to do it and nowits so
much better. This confidence building was helped by the tutors
willingness to give his students time and to extend their computer
skills and knowledge: He just sat me down and showed me how to use it
and then I went away and it made everything so much quicker. By the end
of the third year most were confident users: using the net quite a lot
for their dissertation and project. One student: actually emailed
authors because I couldnt find the articles.

<P>
One effect of using skywriting has been social. Weve started talking
about it outside the lectures, getting people talking, thats whats been
nice the whole atmosphere, its like a breaking of ice. I felt this year
Ive just been talking to so many more people within the year because
you read their skywriting comments you are more likely to just say Hi!;
You can just speak with people as you wouldnt have done before because
youve heard their name, all the sorts of contacts have become a little
bit more diverse. The students were interested in what others have to
say and felt encouraged to talk about their skywriting contributions.
Much of this interaction took place in the computer room of the
department. Everybody will sit in the computer room and either do it
[skywriting] at the same time or theyll talk about what they are going
to do or you have interactions with whos commenting on you.

<P>
Using skywriting they have come to appreciate the benefits of having:
somebody arguing with you as it helps: to crystallise things. They have
also become shrewd judges of whose contributions to look out for. One
student described this as: the filtering effect; you pick up on the
people who have got the grasp of this subject and you think Oh!, Ill
read her, shes good at this. Thus they have learnt to take the best
from their peers while at the same time feeling a commitment to make
good contributions themselves. For most on the course learning has
become a less solitary experience: Talking amongst ourselves is very
important but is only done in relation to [this tutors] course.

<P>
Both in the first year and the third, the students were interested in
each others contributions, even when some were sceptical of their
validity and worth. In part this was because they provided a basis for
social comparison, establishing where they stood in the intellectual
hierarchy. A corollary of this was an anxiety about being shown up.
Such fears seemed to be allayed by time and familiarity with each
other. By the third year, as one student put it: they know where you
are coming from, know that you are not stupid. If you say something
thats nonsense, they wont think this person is dim. Such confidence was
particularly apparent amongst those who had used skywriting in the
third year seminar option.

<P>
The tutor felt that over the three years, skywriting helped to build a
relationship between himself and his students. There was a kind of a
shared intellectual mission sense that I got, and I think it was to a
great extent because of skywriting. In the first year he was skywriting
a few hours a day, typically late at night. When they were coming fast
and furious they were getting answers within 24 hours, within 12 hours
some of them and thats when it was the most enjoyable. It was stressful
and taxing [but] I also think it was fruitful. In the third year course
he was less intensively involved, but he felt that skywriting: brought
down a few barriersyou can be with students for three years and never
have one intellectual spark, exchange, and I got the feeling that a
little bit more of that did happen. Using Skywriting didnt cut down on
room visits by students; in fact the effect was opposite. They come to
see me a little bit more than they did without it.

<P>
Over the three years the students who used Skywriting made that bit
more investment in their learning. Frequency of use led to more
positive evaluation of the medium. Its perceived merits, ranging from
accessibility and immediacy to interactive and reflective potential,
outweighed its negative features (which included the time it takes to
read everything and having to read so much off a screen).

<P>
Nonetheless, when faced with a choice between having more face-to-face
discussions (tutorials/seminars), more lectures or more skywriting, the
students in both their first and their third year favoured more
face-to-face discussion, followed by more lectures. Thus the students
were very happy to have skywriting as an extra resource but were not
keen to have it substitute for contact time with the tutor and fellow
students.

<P>
For campus-based universities, this finding may come as a relief, since
it is apparent that, at least for these students, face-to-face
interaction is still strongly preferred as a learning resource. Our
observations show, however, that CMC (here in the form of skywriting)
can offers an adjunct to such interaction which is capable of adding
significant value to the experience of campus-based study.
