##### Teaching Rationale And Relationship

Non synchronous activities provide the core materials as well as guidance for further reading. Synchronous small group teaching offer the opportunity for practice in the analysis of a system's models and a system's behaviour. Some aspects of the course are further re-enforced through MATLAB Simulation.

#### Assessment Methods

The format of resits will be determined by the Board of Examiners

##### 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.

Description Semester When Set Comment
Computer assessment1MStudents’ Matlab simulations will be formatively assessed using discussion boards and within the synchronous Matlab sessions.
##### Assessment Rationale And Relationship

There are three assessment methods for this module;
A coursework assessing the students' knowledge of the core material of the machines part.
A 3-hour open book assessment carried out with access to lecture notes and use of Matlab/Simulink simulation software. This is to assess the students' ability to apply the course material to a more practical situation, in simulating and obtaining results from various control scenarios.
Formative assessment of the students’ Matlab-based simulation work.
