## Assessment pattern

Assessment type Unit of assessment Weighting
School-timetabled exam/test TUTORIAL PEER ASSESSMENT SCHEME 10
Examination Online 4HR ONLINE (OPEN BOOK) EXAM 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 you 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.

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

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

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

The examination is essential to judge the level of understanding of this basic theory and the TPAS encourages independent learning and provides a regular test of progress throughout the semester.

Formative assessment and feedback

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

• During lectures, by question and answer sessions and discussion

• During tutorials/tutorial classes

• During meetings with the module coordinator and other contributors

• Via the Year 1 Tutorial Peer Assessment Systems

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

• The TPAS coursework is designed to help you develop your resourcefulness and resilience by asking questions based on taught material and how to generalize that material.

• During supervised laboratory sessions in module EEE1027 “Laboratories, Design and Professional Studies 1”

## Module aims

• Introduce the fundamentals of circuit analysis and analogue electronics. It is a basic introduction to electronic theory for a set of electronics based programmes.
• The module is needed to provide the basic underpinning theory of electronics on which future years and modules will build. These modules include: EEE1034 Electrical Science I;, EEE2033 Circuits, Control And Communications¿ EEE2045 Electrical Science II. It provides key steps in developing digital capabilities with introduction to electronic components of digital systems and access to digital learning system with the surreylearn environment which provides lecture material and support with formative assessment with a range of feedback questions for each element of the module.
• It provides the underlying theory for practical laboratory work carried out in modules such as: EEE1027 Laboratories, Design & Professional Studies I, EEE1028 Laboratories, Design & Professional Studies II, EEE2036 Laboratories, Design & Professional Studies III and EEE2037 Laboratories, Design & Professional Studies IV¿
• It's contribution to learning is an understanding of the basic concepts that are used and built upon in future years
• It provides an introduction to resources to support learning and their use to develop a resilient approach to learning.

## Methods of Teaching / Learning

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

• communicate knowledge and information on basic electronic circuits

• engage students in the analysis and understanding of basic electronic circuits through a combination of theory lectures, tutorials problem sheets.

• communicate knowledge on ethical behaviour in work environment through lectures;

• communicate information on opportunities in electronic engineering paths through lectures.

You 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 and designed to prepare you for later parts of your course.

Learning and teaching methods include a set of face to face and recorded lectures, tutorials with lecturers, optional formative problem sheets with answers sheets and problem classes, tutor peer assessment system of summative assessment, online resources, link to recommended textbook available in library. In summary:

• Lectures problem classes – these are both during lectures and at tutorials run by the lecturers where students are supported in using the material you have learned to solve new problems, thus developing your resourcefulness and resilience.

• Tutorial problems with peer marking formative test – this is the Tutorial Peer Assessment System (TPAS) system which involves three problem sheets (the first a couple of weeks into term, the second in the middle and the third at the end) which are marked by your peers in a tutorial class. Marks are then discussed with your personal tutor

• Feedback – this is based on the TPAS marks and the tutorial sessions with the lecturers.

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.

## Other information

We are committed to developing graduates with strengths in Employability, Digital Capabilities, Global and Cultural Capabilities, Sustainability, and Resourcefulness and Resilience.  This module is designed to allow students to develop knowledge, skills and capabilities in the following three areas:

Digital Capabilities: The module helps develop your digital capabilities from your interaction with the digital teaching systems. Also the material taught provides the basis for understanding digital systems in terms of their underlying electronics. This underlying electronics includes resistors, inductors and capacitors and their circuits which are the building blocks of all digital systems.

Employability: basic electronics knowledge is essential for a range of careers and this module coupled with later modules in this area provides the student with this. Electronics knowledge makes available careers in electronic and electrical engineering, computing, artificial intelligence, general engineering and areas of physical sciences.

Resourcefulness and Resilience: In terms of resourcefulness and resilience students are provided with the means to, and encouraged to look at, a range of sources for information and, for the optional more challenging problems set, to go beyond the taught examples. For instance, in coursework and examinations we ask questions on applications of theories such as Thevenin and Norton models of complex circuits. We also provide more challenging optional questions that combine this with other aspects of the course such as network modelling. Formative feedback throughout the module using problems sheets and the TPAS coursework help you to develop your resourcefulness and resilience.

The pillars of Sustainability and Global and Cultural Intelligence are not addressed directly in this year 1 course on the engineering fundamentals but are developed throughout later modules in the course.
