Formative Assessments

Formative Assessment is an assessment which develops your skills in being assessed, allows for you to receive feedback, and prepares you for being assessed. However, it does not count to your final mark.

Assessment Rationale And Relationship

The coursework provides the opportunity for the student to demonstrate their knowledge and skills developed from the electronic device (semester 1) lecture course material. The exam in semester 2 assesses the student’s knowledge of device fabrication, while the formative oral assessment in semester 2 ensures the student has engaged and acquired key knowledge from the practical device fabrication and characterisation experience.
