Federated Non-Traditional Practical Work for Engineering Education

  2. 2. 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) • • •

  13. 13. “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

  34. 34. 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 notebooks NTPW activities Staff Students Educational Collaboration in practices of community

  81. 81. 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.
