Learning, Teaching and Assessment (LTA) Approach:
The delivery is monthly day release, face to face, within a Graduate Apprenticeship scheme. For a module this equates to 2 hours per day of lectures and 5 hours of tutorial supported by online materials.

The general approach in this module is to make use of presentations and group activities to give examples and case studies. These highlight the need for particular approaches and techniques, and make use of commands to tackle the issues presented. The tutorials follow up on the lectures, providing syntax and practice on the situations and commands discussed. This allows the lectures to minimise detailed discussions on command syntax, flags, and other detailed implementation issues, even though at its heart, system administration is a very practical activity. In this way the lectures can focus on the theory aspects of LO1-4, while the practicals re-enforce this with hands-on activities LO1-4. This includes the specific issues of security and performance LO4.
An example of the case-study approach might be a lecture on forging email ‘from’ fields, so that the email may appear to come from someone other than the sender. The lecture explains how email is sent and packaged, then demonstrates how email can be forged using no more than the telnet. The tutorials would then allow the students to investigate the variations of syntax which the commands involved can utilise, produce fake emails within a safe and isolated environment, then work on email server configurations to minimise or prevent fake emails.
The nature of Linux is largely very stable, but in addition some key aspects are much more dynamic. Some areas are in flux, such as system and the evolution of web services, while other areas require current knowledge, such as vulnerabilities being actively utilised by attackers as well as the growth of DoS attacks and the development of mitigation techniques. These are covered in lectures, and the students are also encouraged to explore those things independently (LO5).
All practicals take place in an online learning environment (linuxzoo.net), which provides administrative access to virtual machines within a safe virtual networking environment. It also uses integrated practical assessments which are automatically graded with feedback. This allows students to work flexibly when required.

Formative Assessment:
Tutorial/practical sessions are used to provide formative feedback for students on the module. During these sessions, module tutors assess and evaluate student performance on tasks relevant to the summative assessment, providing timely feedback which supports the development of students’ capabilities. The formative exercises and associated feedback shall also help students prepare for the summative assessments.

Summative Assessment:
There are two assessments. Firstly, a practical assessment tests student knowledge under supervised conditions as they perform administration tasks on a live system (mostly focused on LO1-3). These may involve user account troubleshooting, security (LO4) and networking configuration, performance issues (LO4), and application management. Students are assessed on their ability to complete the tasks and the time taken. The assessment is open-book.

The second assessment is an exam, and takes the form of a 20 question short answer paper. This is designed to cover all the theory of the module, and focusses on understanding and application of knowledge rather than fact-based recollection. As understanding is the key measure, the exam is open-book. LO1-5.
