[17] Revision

Assessment pattern

Alternative Assessment

Not applicable: students failing a unit of assessment resit the assessment in its original format.

Assessment Strategy

The assessment strategy for this module is designed to provide students with the opportunity to demonstrate the following.

·         The examination measures their level of understanding of the lectured material and their ability to apply it successfully to problems.

The summative assessment for this module consists of a written 4 hour open book examination.

Formative assessment and feedback

For the module, students will receive formative assessment/feedback in the following ways:

·         Students are provided with exercise sheets and model solutions via the module's SurreyLearn site.

·         Timetabled lecture sessions are devoted to attempting these in a tutorial setting.

          ·        Dedicated question-and-answer sessions occur in other lectures.

 

Module aims

• This module aims to introduce student to modern energy efficient electronic and photonic devices concentrating on the fundamental science of operation, device structure and characteristics.

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to enable students to achieve a working knowledge of state-of-the-art optoelectronic devices and of optical systems for application in industry or research.

Learning and teaching methods include the following.

• Lectures and revision classes over 11 weeks of semester. 

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.
