Learning Outcomes



Details of Learning Activities

Students will participate in a variety of teaching methods including: lectures, tutorials, practicals, class discussion, 
group/individual work on projects, audio-visual presentations, and interaction with individuals and groups from the Automation industry.

It is expected that students will require at least 3 hours per week for independent study (in addition to the scheduled sessions) to do program development work.
