## Assessment pattern

Assessment type | Unit of assessment | Weighting |
---|---|---|

School-timetabled exam/test | TUTORIAL PEER ASSESSMENT SCHEME | 10 |

Examination Online | 2 HOUR ONLINE (OPEN BOOK) EXAM IN A 4 HOUR WINDOW | 90 |

## Alternative Assessment

A student required to resit the TPAS unit of assessment is required to re-submit written answers to all TPAS questions relevant to the module. This re-submission is assessed by the TPAS Coordinator on a pass-fail basis only.

## Assessment Strategy

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

· That they can recognise common electronics components and circuits, recognise the purpose of a circuit. and analyse the properties of electronics systems. This involves both analytical and recognition skills.

Thus, the **summative assessment** for this module consists of the following.

· A 2-hour online, open-book examination in a 4-hour window (90%).

· Three sets of problems assessed via the Tutorial Peer Assessment System (TPAS) (10% in total).

For exact TPAS submission dates, see the Departmental assessment calendar issued to you.

**Formative assessment and feedback **

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

· During lectures, by question and answer sessions

· During tutorials/tutorial classes

· Via the Year 1 Tutorial Peer Assessment System

· By means of unassessed tutorial problem sheets (with answers/model solutions)

· During supervised laboratory sessions

## Module aims

- Introduce the fundamentals of circuit analysis and analogue electronics. The module will enable students from different educational backgrounds to reach a common level of knowledge and understanding.

Attributes Developed

**C** - Cognitive/analytical

**K** - Subject knowledge

**T** - Transferable skills

**P** - Professional/Practical skills

## Methods of Teaching / Learning

**The learning and teaching strategy** is designed to achieve the following aims.

The student should complete the course with a thorough grounding in elementary analogue electronics. The material is listed above. The level of experience is at introductory university level ad designed to prepare them for later parts of their course.

**Learning and teaching methods** include the following.

- Lectures
- problem classes

tutorial problems with peer marking

formative test

feedback

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.
