6.10 To extend or include?

Whatever kind of system you intend to develop, you will need to consider its security. Usually, we allow only trustworthy people to use a new system. Therefore, in a software solution we can envisage a log-on use case, which describes how a user gains access through some authentication procedure. How should such a requirement be included in the example of the hotel chain?

By analogy with natural languages, the UML allows a number of ‘grammatically correct’ options each of which will

Children and young people’s participation
Listening to children is a first step in the participation agenda, which is reasonably well established. By contrast, enabling children to share in decision making lags some way behind. This free course, Children and young people's participation, emphasises that the adoption of an integrated approach to participation by different sectors of the children's workforce is of crucial importance.Author(s): Creator not set

9.1 Reflection and the four main phases of learning how to learn

If your course encourages this approach to learning, or if you have read other material on learning how to learn, you may have come across the term 'reflection'. Maybe you have been encouraged to reflect on your learning or on your assignments. In this course, we have deliberately not used the term until now. This is not because we think the term - or the process - is unimportant, but because it can seem vague and not particularly helpful to you as a learner. In fact, all the activities in th

8.5 Reviewing

Undoubtedly this is the most difficult phase to apply to revision and an exam or to the preparation and production of an end-of-course assessment. Most of us heave a huge sigh of relief when it is all over and then try to put it out of our minds during the weeks while we wait for the results. When these arrive, it is very difficult to think back to the exam itself or revisit the details of the end-of-course assessment. With very little feedback to help, learning how to learn from exams or the

4.1 Preparing

In the preparation phase you should pause before starting a new section of work and think about it as a whole. What needs to be covered? What are the various components of this block of work? What are the learning objectives or outcomes? What will you need to know and be able to do at the end of it? What is required in the assignment?

There are two main activities during this phase, both directly related to your course work and assignment:

5 Effective use of information technology

The purpose of this course is for you to create a portfolio of your work to represent you as an effective user of information technology (IT) within your study or work activities. This will involve using criteria to help you select examples of your work that clearly show you can use and improve your IT skills. However, by far the most important aim is that you can use this assessment process to support your learning and improve your performance overall.

1.1.3 Keeping the calculator running on your Windows desktop

When performing a number of calculations whilst using other programs on your computer, it's convenient to keep the calculator running in the background.

To do this click on the 'Minimise' button of the calculator's window (the leftmost button in the top right corner). When you are ready to start working with the calculator again, click the 'Calculator' button in the Windows taskbar. (The taskbar is usually at the bottom of the screen; it contains the 'Start' button.)

As a student, you're likely to engage in a variety of writing tasks. You'll almost certainly handle significant amounts of text and, depending on your course, perhaps also numbers or diagrams.

This section looks at the different way that you write using a computer, and also provides some referencing advice.
