where students can interact
with the tutor and delivery
can be tailored according to
students’ abilities and
learning styles.
Formative assessments
provide opportunity for
ongoing formative assessment
of student progress and
feedback to students and feedforward.
Computer software , in particular
MATLAB, will be provided as tools
for the students.
Classroom teaching is
supported by hands on

Feedback is continuous
throughout the course with online interactive test questions
on the LMS, group activities
and lab progress feedback. This
