2 Part II Course Details 1. Abstract The course is designed for the senior undergraduate students in the BSc Applied Physics program. The course will provide students basic knowledge of electrodynamics at the introductory level so that they can proceed to advanced courses in the BSc Applied Physics program. Mathematical tools such as vector calculus will be reinforced throughout the course. 2. Course Intended Learning Outcomes (CILOs) (CILOs state what the student is expected to be able to do at the end of the course according to a given standard of performance.) No. CILOs # Weighting* (if applicable) Discovery-enriched curriculum related learning outcomes (please tick where appropriate) A1 A2 A3 1. Recognize and explain the physics laws governing the behaviour of electromagnetic quantities. 2. Solve introductory level electrodynamics problems using vector calculus. 3. Analyze electromagnetic problems using special mathematical techniques for physics. 4. Relate theory of electromagnetism to electromagnetic field subjects. * If weighting is assigned to CILOs, they should add up to 100%. 100% Please specify the alignment of CILOs to the Gateway Education Programme Intended Learning outcomes (PILOs) in Section A of Annex. A1: Attitude Develop an attitude of discovery/innovation/creativity, as demonstrated by students possessing a strong sense of curiosity, asking questions actively, challenging assumptions or engaging in inquiry together with teachers. A2: Ability Develop the ability/skill needed to discover/innovate/create, as demonstrated by students possessing critical thinking skills to assess ideas, acquiring research skills, synthesizing knowledge across disciplines or applying academic knowledge to self-life A3: Accomplishments Demonstrate accomplishment of discovery/innovation/creativity through producing /constructing creative works/new artefacts, effective solutions to real-life problems or new processes. 3. Teaching and Learning Activities (TLAs) (TLAs designed to facilitate students achievement of the CILOs.) TLA Brief Description CILO No. Hours/week Lectures/Student Centred Activities/ Explain key concepts, build mathematic foundation and analytical skills, provide examples and solutions of advanced problems in electricity (if applicable) 3 hours/week 2

3 4. Assessment Tasks/Activities (ATs) (ATs are designed to assess how well the students achieve the CILOs.) Assessment Tasks/Activities CILO No. Weighting* Remarks Continuous Assessment: 40% Assignments 20% Test 20% Examination^: 60% (duration: 2 hours) * The weightings should add up to 100%. 100% ^ For a student to pass the course, at least 30% of the maximum mark for the examination must be obtained. 3

4 5. Assessment Rubrics (Grading of student achievements is based on student performance in assessment tasks/activities with the following rubrics.) Assessment Task Criterion Excellent (A+, A, A-) 1. Assignment Capable to show a good understanding of the taught materials from solving the given 2. Test Ability to solve common electricity 3. Examination Ability to grasp the concept of the taught materials and to solve common electricity Good (B+, B, B-) Adequate (C+, C, C-) Marginal (D) Failure (F) 4
