Within your course, tables are likely to be used as a particular structured format to summarise numerical information. They tend to be used to present data as a summary and as a starting point for discussion. But someone always prepares tables. So always be aware of where the table that you are looking at has come from. Could the source be trying to tell you something in particular? For example, if a table were summarising the costs of running a hospital, would you expect figures from the gov

After studying this course, you should be able to:

• reflect on the reasons for needing to improve skills in using charts, graphs and tables

• understand the following mathematical concepts and how to use them, through instruction, worked examples and practice activities: reflecting on mathematics; tables; line graphs; bar charts and histograms; pie charts; analysis

• draw on a technical glossary, plus a a list of references to further reading and sources

Bar charts show data in the form of bars that illustrate the relationship between the items of information in terms of size: the bars get larger (generally taller) as the amounts being shown increase.

When the bars touch, they show continuous data. In other words, data that changes gradually along some sort of a scale, for example weight, height, temperature, or length (these charts are called histograms, see Author(s): The Open University

A pie chart is a diagram in the form of a circle, with proportions of the circle clearly marked. A pie chart is a good method of representation if we wish to compare a part of a group with the whole group. It gives an immediate idea of the relative sizes of the shares. So, for example, it can be used to consider advertising income. It can also be used to look at, say, shares of market for different brands, or different types of sandwiches sold by a store.

Even when you have used your own words it is essential that you acknowledge the source of the ideas you re-present. This entails making a note of the author and date of publication of the material from which you extract key concepts and points. So at the end of our summary of the Croall extract above, we would need to acknowledge that we got our information from that source by putting (Croall, 1998) at the end of the relevant paragraph. If you use more than one author's work in a paragraph th

I assume that you are reading this course because you would like to create a course similar to the materials that you can find on the OpenLearn website. You therefore have a teaching purpose and are particularly interested in the use of online tuition. Hopefully you are also keen to share your teaching materials with others. But why bother creating a new OER? Surely there is so much material already available for free on the web anyway!

I would answer this in a number of ways. First: qu

When seeking content for adaptation and re-use in open educational contexts there are several tools available to support discovery. Many of these tools are the result of experimental prototyping and short-term funded projects, however, and therefore carry with them a certain amount of risk. Not all are sustained beyond the life of the funding, but these initiatives have sought to use a variety of search technologies to support the discovery of generic and domain-specific OERs. As we move forw

## What is an open educational resource?

The term ‘open educational resource’ is one that encompasses a broad range of items. It can describe a single image or an entire short course, and materials can be in any medium or a mixture. The Organisation for Economic Co-operation and Development (OECD) has defined OERs as ‘digitised materials offered freely and openly for educators, students and

Introducing ageing
Everyone is ageing, whatever their current age, and we live in a world where many people are living much longer than previous generations. This is often seen as a problem. But is it? This free course, Introducing ageing, will help you to think about this issue by introducing you to some key ideas in studying later life. First published on Thu, 18 Apr 2019 as Author(s): Creator not set

This free course provided an introduction to studying Health and Social Care. It took you through a series of exercises designed to develop your approach to study and learning at a distance and helped to improve your confidence as an independent learner.

Dev Sharma’s arrival at the Durrants’ home, following an incident involving a knife, is an example of an ambiguous situation. The morning after the incident he has to visit the Durrants, having received a telephone call from the home carer, reporting a claim by Arthur that his daughter, who has learning difficulties, has threatened him with a knife. Dev has to initiate a risk assessment. But what exactly happened and how should he set about his duties?

As a social worker Dev

Enid Francis lived in a modern residential area on the outskirts of Derby. She shared a house with her husband, Wally, and two grown-up sons, Mark and John. Her husband had had to give up work eighteen months before his retirement, because of a heart complaint. Their two sons, aged 35 and 32, were both autistic. Enid's day was organised around meeting their needs for care and support. On weekdays, they attended a day centre, which she would have to get them ready for. When they came home in t

A hostel, which provided accommodation for 13 people, predominantly men, in individual rooms and an overflow shed. It was run in partnership with the Family Housing Association. Three-quarters of its funding came from the Welsh Assembly, and a quarter from the local authority.

Another important source of revenue was Housing Benefit, through which residents were able to pay their accommodation charges. This varied enormously. Residents classified as ‘vulnerable’, like those with ment

There is a wide range of quantitative models, of varying degrees of sophistication and complication. In this pack, we will only cover those that I think you are likely to encounter in systems studies or could use to good effect. The techniques available subdivide broadly into two major classes, static models and dynamic models. The distinction between these will become clearer as you look at some detailed examples. Essentially, dynamic models are those where the set of calculations comprising

Not much of this unit conforms to the traditional pattern I mentioned earlier – the theory-example-exercise pattern. In particular, you will find you are expected to discover much of it for yourself. Why is this? This is a legitimate question and deserves a full answer. One year, a student at a residential summer school complained I had not taught him properly. I was, he told me, an expert and so why did I not demonstrate how to tackle the problem he was working on and pass my expertise on

A practising engineer makes ethical decisions, with moral and physical implications of varying magnitudes, on a daily basis. Examples of ethical dilemmas are limitless, ranging from the engineer who takes home the odd pen, file or discarded paper 'for the children', to the engineer who signs off a project without checking the details and identifying a simple arithmetic error of magnitude. The implications of either may be negligible – such as where the cost is more than compensated in unpai

Before moving into a discussion of the missing element of the rich picture, I want to direct your attention to all the thoughts and ideas I have encouraged you not to put into your rich picture. I imagine you might have collected quite a list of loose ends. The next activity will involve some of these.

Expect to take about half an hour to do the next activity.

As it's sometimes difficult to say whether a particular innovation is radical or incremental, a useful distinction made recently is between sustaining innovations and those that are disruptive. You'll read more about these ideas in Part 3.

Briefly, a sustaining innovation is a new or improved product that meets the needs of most current customers and serves to sustain leading firms in their market position. So in this context improvements to gas lighting, say, would be sustaining
