* Teacher info: 5.1 Remind pupils that the system is being
designed to enable a travel agent to look up weather information for
customers. Ask pupils to work in pairs to discuss what they would like to
change. Ask one of each pair to jot down the suggestions. After 5 minutes,
gather pupils’ ideas. Use these questions to prompt if necessary. ·
How easy is the system to use? ·
What do you have to do to change the
location? ·
What do you need to know about the URL? ·
How attractive is the graph? ·
What other information would the travel
agent need? ·
What impression does the output worksheet
give? Draw out
responses. ·
The system is difficult to use. ·
The user needs to know about and be able
to use URLs. ·
It is easy to make a mistake in entering
the location. ·
The graph is not very attractive. ·
The output worksheet looks unclear and is
not well presented. ·
The user, a travel agent, expects the
system to be quick, accurate and easy to use. ·
The system uses ICT to automate the
process of gathering data and presenting the information to meet the user’s
needs. 5.2 Explain that you are going to
demonstrate a feature of a web query which will help to make the system more
user-friendly. Show sample system 8.1T5b
lesson5.xls on the large screen. Point out that it is the system they
developed, with one change. Move to the ‘Output’ worksheet and demonstrate
what happens when the location in cell A1 is changed. Note:
the web query will not work if there is no live Internet access. Show how
the data are collected from the website, processed and displayed
automatically. Ask pupils if this helps to make the system easier to use. 5.3 IMPORTANT The
students will not be putting the string into student5_4.xls as this is very
tricky. This is presentation will just show them how it was
done. 5.4 Ask pupils to think about how the information
is displayed, reminding them that the system is being designed for a travel
agent to look up weather information for customers. Remind pupils that the
presentation of information needs to be clear, easy to read and understand.
Ask for suggestions about how to enhance the presentation of information.
Give pupils 2 minutes to think of suggestions before selecting pupils to
respond. Draw out points such as: ·
providing on-screen instructions; ·
changing the type of chart to a more
appropriate one; ·
changing the scale on one or both of the
axes; ·
removing gridlines, scroll bars, etc.; ·
enlarging fonts, changing font typeface
or colour; ·
changing the colours of the background,
lines, bars, etc. Add
suggestions to the list on the whiteboard from activity 1. Ask
pupils to modify their systems, taking into account these suggestions. Say
that at the end of the lesson they will return to the list to judge how well
their system meets the needs of the user. Give pupils help sheets or
guidelines, as appropriate, or direct them to the help menus in the
application. Undertake
focused group work with pupils working at a higher level. Prompt pupils to
reflect on their system by asking these questions. ·
