Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate the full range of learning outcomes through exam, tutorials problems solving, Group project for sustainability part to test both fundamental understanding as well as integrative understanding in solving practical questions.

Thus, the summative assessment for this module consists of:

·         Examination – 70%, 2 hours, assessment of both Materials and Sustainability elements, (LO1, LO2)

·         Coursework (Materials) – 10%, 2 hours, (LO1)

·         Project (Sustainability) – 20%, 18 hours, (LO2, LO3)

Formative assessment

None

Feedback

Weekly verbal feedback will be given during tutorial classes.

Written and verbal feedback on Materials Coursework

Written and verbal feedback on Sustainability Project

Module aims

• Define and discuss the main mechanical properties and durability of engineering materials and to review the salient features of the main classes of materials in the context of these properties. In addition, factors relating to materials selection and design will be addressed. 
• Introduce students to the environmental, economic and social constraints that need to be considered by engineers and to put engineering in its global context and thereby to provide students with the conceptual understanding they will need to pursue professional careers

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

For the Materials element

• Use a combination of lectures and tutorials to develop an understanding of mechanical behaviour of a wide range of materials including metals, ceramics, polymers and composites


• Give emphasis to the relation between materials microstructure, mechanical properties and processing, and introduce the parameters which govern the use of these materials in engineering applications


• Enable students to select suitable materials for particular engineering applications

• Use a combination of lectures, case studies and group projects to develop an understanding of sustainability and the analytical skills to assess the sustainability of systems


• Use case studies and projects to develop problem solving skills for practical engineering cases


• Encourage team working by using group projects

• Lectures                                3 hours per week for 11 weeks


• Tutorial/Problem Classes       1 hour per week for 11 weeks 


• Group project                         3.6 hours per week for 5 weeks


• Independent learning             7.3 hours per week for 12 weeks (average)

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
