ular students who: 1) took the course this year, 2)
attended the lectures, and 3) were active during the
project work. Figure 4-6 show the histograms related
to the three types of presence.
In addition to these histograms, even if not shown
in this paper, sub-scale scores were computed for each
respondent for each of the three scales as a mean value
of the numerically coded responses. For sake of clar-
ity, it shall be stated that the questionnaire was not
proposed as an anonymous questionnaire. The rea-
son for this choice is twofold: 1) “students should
be treated as adult partners and that an objective
and open exchange regarding the performance quality
must be possible”; 2) studies such as (Scherer et al.,
2013) point out that “no significant differences are
identified in the informative quality of data between
the anonymous and personalised student evaluations”.
From a quantitative and throughput-focused per-
spective, the throughput after the first examination
in relation to the written exam, if compared with
the previous instance, decreased negligibly (this year,
72,22% passed the written exam, while 73% passed
the written exam last year). In relation to the project
work, instead, the throughput increased (this year,
89% passed the project after the first examination,
while only 82,75% passed the previous year). From
these numeric results, it emerges that the throughput
did not suffer by having moved the teaching on-line.
As mentioned, my threefold purpose with this
questionnaire/results-analysis was to: assess the im-
plementation of the Community of Inquiry Model,
better understand the limits of moving the course on
line, and elicit areas of improvement given that likely
education on-line is now here to stay.
Based on the answers received (8 students pro-
vided their answers, i.e., 50%), the main lacking as-
pect resulted to be the social presence. From a teach-
ing and cognitive presence, the respondents were
globally satisfied. Concerning timely feedback, this
year, it was an exceptional situation due to the short
notice sick-leave of the course assistant. Given this
limited but stil talkative results, it emerges the need
of substantially enhancing the social presence. How-
ever, room for general improvement is present.
6 CONCLUSION AND ROADMAP
In this paper, I reported about my experience in
pedagogically redesigning and implementing an on-
line version of an advanced master course on safety-
critical systems engineering, conceived and deliv-
ered as a series of Zoom-based, and community-of-
inquiry-oriented meetings plus Canvas-based threads
of discussions for educating the minds of future safety
and software engineers. Based on the results from the
first instance, a roadmap for near-future development
can be sketched as follows. To improve the social
presence, I plan to:
• introduce a Zoom-based lecture-zero, during
which we could create a virtual round table and
present ourselves;
• use break-out rooms before and after the lectures
to create the virtual corridor facilitating small-
talks.
• open Canvas-discussion-forum for enabling stu-
dents to professionally present themselves in re-
lation to a set of assumed skills, which are helpful
for project work. This year a discussion forum
was opened but not in a structured manner and as
a consequence it was not exploited as expected.
To improve the cognitive presence as well as increase
contexts for social constructivist learning, I plan to:
• use break-out rooms to enable students to work
in small groups and solve the typical 2-3-minute
exercises;
• use polls to assess the individual cognitive pres-
ence;
To improve the teaching presence, I plan to:
• make explicit for the students the usage of tech-
nology in relation to a specific learning perspec-
tive and type of presence. This should allow me
to extend the COI-specific survey to get feedback
from students with respect to the effectiveness of
the usage of specific Zoom-or-Canvas features.
• introduce an exit-questionnaire for each lec-
ture to understand if the questions/challenges
asked/posed within the lecture can be an-
swered/faced by the individual students.
As future development, inspired by (Zhu et al., 2019),
I also plan to explore Computer-Mediated Discourse
Analysis (CMDA) for analysing the participation in
online discussion and students’ learning behaviours in
relation to CoI presences. A more formal evaluation is
expected to be addressed, implemented, and analysed
based on data collected over a longer period, com-
prising multiple DVA437-course instances, possibly
based on a larger sample of questionnaire responses.
