# ELECTRONIC CIRCUITS - 2021/2

Module code: EEE1025

In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.

These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.

Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.

Assessment pattern

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

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

Examination | 2 HR CLOSED BOOK EXAMINATION | 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 two-hour, closed-book written examination (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.

Overall student workload

Independent Study Hours: 55

Lecture Hours: 33

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.
