Federated Non-Traditional Practical Work for Engineering Education

Federated Non-Traditional
Practical Work for
Engineering Education
Professor Timothy Drysdale

Note on slide content
• This is a larger slide deck than I could have presented at
EUCAP
• It is from a talk I gave at NI Days Europe in Munich October
2019 (I choose this approach due to extreme operational
workloads leading online exams at this time)
“Breaking News”: For those that may be interested – I made a
PDF exam marking system (in use by for School of Engineering
exams, and default in School of Maths)

The future is
already here
— it's just not
very evenly
distributed.

“How do we deal with this expansion [of student numbers]?
How do we still engage students early on with the world of
engineering? How do we show them the messiness of
engineering, the political and social aspects? ... How do we do
this beyond the capstone project? This type of education, the
type of education we want to have, is expensive. So how do
you do this for all students, large cohorts of students, without
compromising on everything?”
R. Graham, (2018) “The global state of the art in engineering
education,” New Engineering Education Transformation,
Massachusetts Institute of Technology, Cambridge, MA, USA

Understanding student and staff practice

Should we be
teaching ‘best’
(only one)
practice?

“In the software-centered future, individuals and institutions won’t compete with computer
programs so much as they’ll compete with each other over who can work best alongside
computers.”

Open-ended practice
As the students move to more senior years, user interfaces should
become more open-ended. For project work, activities might be
programmed directly by the student and/or the data analysed in Jupyter

WebRTC pain points for
unattended experiments?
- system complexity
- connection anxiety
- connection time
- automated camera serving issues
- moving target
- non-human uses cases are edge
(Been there done that, for the last lab,
but not appropriate this time around)

NTPW supporting practices of community
• What then can be done in higher education to provide
experience of this?
• Subject knowledge has long-term relevance, and staff are
authorities, so it cannot be done in the existing curriculum.
• NTPW activities offer a rapid refresh and update cycle (unlike
conventional laboratories), where students engage with leading
edge technological concepts.
• Posthuman gaze: Observe and support the behaviour of
relations between the technologies, senior students, tutors, and
staff when handling newer technologies/concepts before the
concepts and practices around those technologies have
stabilised.
