Overview of Assessment

This is a progressive assessment, the students are required to undertake summative assessments which include:
Practical laboratories, written reports for the laboratories, project, and written assessments


Assessment Tasks

1. Laboratory exercises (12%)
Each student will complete seven practical exercises designed to reinforce the theory topics taught during the semester.
Most practical exercises consist of two major parts:
Part A is a prior task includes only calculations (usually pre requisite for part B) and part B include measurements and graphs.
The results obtained in part B will be reviewed and compared with the calculations from section A.
These will be assessed progressively according to individual task criteria and each student is required to complete a short written report for each laboratory exercise.
All laboratory exercises must be undertaken according to safe working practice and performed according to specified laboratory standards and practice including calibration, measurement and accurate reading. This must include electrical measurement taken with safe working practice, meters properly calibrated, meter settings positioned for an accurate reading and accurate readings taken for all measurements.

2. Project (13%)
A project has to be undertaken toward the end of the unit, in a controlled environment for the specified duration in order to perform tasks autonomously.
The project circuits are constructed using MultiSim (design / test) simulation computer package. Each student will complete all parts of the project individually and will be asked by the supervisor to demonstrate that the circuit is functioning according to specifications. Each student is required to complete a written report includes three major parts: calculations, circuit diagrams / measurement and results / conclusion.(2% each)

3 Mid semester written Test (25%)
Theoretical concept covered in weeks 1 to 8 will be assessed by a written test in week 9.

4 End of semester written Test (50%)
Theoretical concept covered in weeks 9 to 16 will be assessed by a written test in week 17.
