Additional assessment information

As a part of the assessment, you will write an assay (approximately 3000 words) on a theme involving an application (preferably innovative) of either MEMS or Microfluidic system in the area of your choice.

An area of application could be any (but not limited to) from the following categories: automobile, aerospace, communication, road safety, structural safety (mechanical and civil), oil & gas or Bio-Medical Engineering.

The first part of the assay should include an explanation or a reason for selecting the specific application, how this application area is being served currently, a commentary on currently used commercial devices, their limitations and how the proposed device would address the limitation. This part should also include relevant literature and references. (Part 1: 30 %).

The later part should explain the proposed device for specific application with the principle of operation, supporting drawings and literature, range of operation (if applicable). There should be a narration on current competing technologies and commentary on a future potential of the proposed device (Part 2: 70%).

Module feedback

'Feedback’ at a university level can be understood as any part of the learning process which is designed to guide your progress through your degree programme. We aim to help you reflect on your own learning and help you feel more clear about your progress through clarifying what is expected of you in both formative and summative assessments. A comprehensive guide to feedback and to forms of feedback is available in the Guide to Assessment Standards, Marking and Feedback.

The School of PET aims to provide some form of feedback on all formative and summative assessments that are carried out during the degree programme. In general, feedback on any written work/assignments undertaken will be sufficient so as to indicate the nature of the changes needed in order to improve the work. The School will endeavour to return all exam feedback within the timescale set out in the University's Policy on Assessment Feedback Turnaround Time. The School would normally expect to adhere to the times given, however, it is possible that exceptional circumstances may delay feedback. The School will endeavour to keep such delays to a minimum. Please note that any marks released are subject to ratification by the Board of Examiners and Senate. Meetings at the start/end of each term provide you with an opportunity to discuss and reflect with your supervisor on your overall performance to date.

Formative feedback:

During demonstrations or practicals in the laboratory, verbal help and feedback will be provided to support development and understanding of micro-fabrication skills.

In classroom spoken feedback or answers to the queries will be provided during and after the lectures.

The students will also have an opportunity to have technical discussions with the module Coordinator during sessions in office hours.

Emails from the students in the form of queries will be answered by the module coordinator as soon as possible.

The information on this page is indicative of the module that is currently on offer. The University is constantly exploring ways to enhance and improve its degree programmes and therefore reserves the right to make variations to the content and method of delivery of modules, and to discontinue modules, if such action is reasonably considered to be necessary by the University. Where appropriate, the University will notify and consult with affected students in advance about any changes that are required in line with the University's policy on the Approval of Modifications to Existing Taught Programmes of 四虎影院.
