Flipping the Classroom Experience
Rationale for reducing lecture time
(suck it and see)
Advantages
Disadvantages
Free up time
Less time for interaction
Less emphasis on content
Less able to convey myself to
the students
More focus on core material
Less time for ‘jokes’ …
Increase responsibility of
students to be engaged
Less time to tell them …
Frustration – how else will they
know??
More expensive overall ??

Lessons Learnt
• eValuate Comments
– As expected – the good, bad and ugly
• Some Good comments
– The weekly tutorial activities are a great way for us to refresh and
study the content learned in the lecture.
– the tutorials activities were for me the best way to learn the
concerned subject each time.
– The videos from the past years was really useful in helping me
understand certain topics better.
– The short revised lectures were helpful, with the addition of more
detailed lectures available on blackboard.
– Where diagrams and movies are presented, make it much easier to
visualise the systems we are studying. Technical drawings are not very
good at helping see what it is we are supposed to be seeing
– The tutorials are the most helpful bycovering the practical aspect of
the subject that are tought.
– good lecturer and lots of notes available
Lessons Learnt
• Some Poor comments
– I found that the lectrues mostly focused on deriving
equations and not enough time was spent on worked
examples. I found the quality of the lecture notes
poor and I also had a tutor that was not only
extremely difficult to understand, but his hand
writing was also unreadable making coming to the
tutorials almost pointless. The fact that every
member in the group assignment had to attempt all
questions was frustrating as well.
– The lectures were generally unhelpful and the
tutorials were similar. The labs were also unhelpful in
understanding content especially as it had not yet
been studied in most cases
Lessons Learnt
• Student comments for
improvements
– Increase tutorial time to 2 hrs
– Improve quality of tutorial sessions
– Increase time between lecture and tutorial
Future Modifications
•
•
•
•
•
Increase tutorial time to 2 hrs
Improve quality of tutorial sessions
Increase time between lecture and tutorial
Try out some in-class tutorial assessments
Try out some on-line quizzes
Conclusions
• Reducing lecture time appeared to have little
bearing on student engagement
• Student engagement can be increased using
compulsory tutorial activities
• Overall student grades improved giving
encouragement for further developments in
2014
