# LINEAR ALGEBRA - 2021/2

Module code: MAT1034

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 | IN-SEMESTER TEST (50 MINS) | 25 |

Examination | EXAMINATION - 2 HOURS | 75 |

Alternative Assessment

None.

Assessment Strategy

__The assessment strategy is designed to provide students with the opportunity to demonstrate: __

That they have learnt the basic material in the field, and are able to apply it to examples and problems.

__The summative assessment for this module consists of: __

· In-Semester Test that constitutes 25% of the final mark;

· Final Examination that constitutes 75% of the final mark.

__Formative assessment and feedback: __

The students will be given exercise sheets every fortnight, and it will be suggested that they work through the examples as part of their independent study prior to attending the seminars. This will aid the students with the development of mathematical technique and knowledge. The students will receive feedback on their work during the seminars and office hours.

In addition, there will be four pieces of unassessed coursework as part of their independent study. This coursework will be marked and the students will receive detailed feedback on this work during the lectures, seminars, and office hours.

Module aims

- The aim of this module is to extend students' knowledge of matrices, vectors and systems of linear equations and to introduce the abstract concepts of vector spaces, linear maps and inner products.

Overall student workload

Independent Study Hours: 101

Lecture Hours: 44

Seminar Hours: 5

Methods of Teaching / Learning

The __learning and teaching__ strategy is designed to provide:

- A detailed introduction to linear algebra and its application in other areas
- Experience (through demonstration) of the methods used to interpret, understand and solve problems in linear algebra

The

__learning and teaching__methods include:

- 4 x 1 hour lectures per week x 11 weeks, with lecture notes provided;
- (every second week) 1 x 1 hour seminar for guided discussion of solutions to problem sheets provided to and worked on by students in advance.

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.
