6.1 Defining amplitude

Another important property of a sine wave we need to be able to specify is its amplitude. In essence, the amplitude of a sine wave is its size. Unfortunately there are various ways of defining what is meant by the size of a sine wave, and you are likely to come across many of them in material you look at outside this unit. Before I explain what our definition is, it will help matters if we look at what is meant by the average value of a sine wave.

1.6.1 The example

Suppose that a couple who have children are thinking about the next family holiday. They list five options, including staying at home. They also list four criteria and they give each an importance weighting on a scale of 1 to 5, where 5 is the most important and 1 is the least important.

3.5 Distinctions about systems practice

A tension has existed throughout the history of Western thought around whether to focus on parts or the whole. The practice that springs from this history carries the same tension. This tension has been particularly visible within science and philosophy for a long time and it gives rise to different approaches. I will be addressing these tensions in Author(s): The Open University

2 Working with memories – life storybooks

Life story books are used more and more by social workers, residential care staff and some foster parents with young people who, for various reasons, need to find ways to remember and talk about earlier parts of their lives. The books may take a variety of forms: photograph albums, scrapbooks, written accounts and audio and video recordings. They may include drawings, poems, family trees, letters, bus and train tickets, photographs, writing and all sorts of ephemera that evoke the past, or pr

3.19 Practical examples of negative numbers

Negative numbers occur in financial matters, in temperature or height measurements and many other practical situations.

3.4 Monitoring progress

Monitoring progress is about keeping track of what you are doing and how well you are doing it as you work towards your targets. It is about being able to make an assessment about yourself and being ‘self aware’ about your own capabilities, how you learn best, things that have helped you and so on. One problem in becoming more aware of yourself and making a self-assessment is that you may not know enough terms to describe yourself. Think of the first time you were asked to describe a pain

4.3.4 Monitor and critically reflect on your use of communication skills

You need to know how to track and record your progress on your use of communication skills. Try to assess the overall quality of your written and oral work and the way you produced the work. Checklists and criteria provided as part of the project or assignment and those set out in the Bookmark can be very useful tools in helping you to assess for yourself precisely what you are doing and how well you are doing it. Unless you know what you are doing wrong, it is very difficult to improve.

2.5 The emperor

With Napoleon's coronation as emperor in 1804, a new type of official image was once again required. Portraits of the emperor in his ceremonial robes were commissioned from several established artists; these all revived a traditional type of royal portraiture from the eighteenth century. The example shown in Plate 10 is by a former David student, Francois Gérard (1770–1837), by now a fashionable portrait painter (see Author(s): The Open University

The concept of self-service has reduced the use of spoken language dramatically, and nowadays shopping transactions may involve no more than the exchange of a few words. However, uses of literacy in shopping are probably increasing, as the next Activity shows.

3.8 Evaluating strategy and presenting outcomes

By now you will have found out about and sampled different resources for learning and used different ways to learn. But the structured approach used in this section is one of the main resources for developing and improving your other key skills.

So how do you know if you have learned? How do you know if you have improved? How do you know if you are meeting the standard for improving your own learning and performance expected of someone doing a course in higher education or using higher

1.1 Preparation for study

One of the main purposes of this unit is to help you develop two kinds of skills:

  • the general skills of being a student

  • some skills which are particularly associated with the way social scientists work.

Both are of fundamental importance to your success in studying other courses. This unit is about the very basic study skills of reading and taking notes. These are basic in the sense that they are the foundation for all su

6.7 Drawing ideas together

This key skill has used a three-stage framework for developing your skills. By developing a strategy, monitoring your progress and evaluating your overall approach, you take an active role in your own learning. But learning does not necessarily follow a path of steady improvement, it involves change: revisiting ideas, seeing things from different perspectives, tackling things in different ways.

You are unlikely to be able to complete your work by working through it from beginning to end
