4. LEARNING AND TEACHING STRATEGY
Students will learn factual material through lectures and guided reading. Tutorials will be used to apply the basic principles. Laboratory work that will be done in a co-requisite separate course will be used to demonstrate concepts and show differences between theory and reality.
Lecture notes will be given to students prior to all lectures. That would help the learners to clarify their doubts during lecture time and make it more interactive.
Problem sheets are given out to students and after time, the problems are discussed in class. Some of the problems will be handed in and then marked by peers to give formative feedback to fellow students.
5. ASSESSMENT STRATEGY
To assess understanding by a written examination
To assess self-learning by an open-ended assignment

7. Strategy for feedback and student support during module
Interactive lecturing style, with opportunities for questions, and requirement to work on simple problems,Peer marking of tutorial questions for formative feedback.
Tutorial classes where students can ask questions and be lead through solutions as required.
Marked assessments handed back to students, with comments.
Opportunities to consult lecturer and/or tutorial assistant in office hours.
