Fawkham is a small rural school with
93 pupils. Our aims were to develop Control Technology throughout Key
Stage 2 and promote the interest of ICT in staff and pupils. This report
outlines the introduction of the Datameter in Years 3/4 and 5/6, and
the Science investigations undertaken by children.
Introducing the Datameter (or another
sensor eg. Logit Explorer)
Give
yourself time to play with the Datameter in order to become familiar
with using it before working with a class.
First,
introduce the light sensor to the children. The changes are immediate,
and it's easy to relate effect to cause. There is a need for discussion
about sources of light and changes in light level - natural, or controlled
by humans. Talk about the use of sensors in the familiar environment.
Let
the children experiment with the sensor. Cover the sensor, then
point it towards a source of light. Children begin to understand the
features of the real-time graphs and what the sensor is recording.
Integrate
the use of sensors into the planning of other subjects. Once
staff and pupils are familiar with how the software and sensors work
then it is possible to incorporate their use into planning for curriculum
subjects. We have been able to integrate sensors into our medium and
long term planning in Numeracy (graph work), Science (temperature) and
Geography (weather conditions locally and around the world.) The use
of sensors has also led to some useful work in English (E-mails to other
parts of the world to exchange temperature readings.)

Class Management
The initial lesson can be with a whole
class. If you have a data projector or large display, this is an excellent
means of demonstrating skills to the whole class. The class together
have the opportunity to talk about graphs as they are produced, and
to answer questions which focus on the graphical features.
The most effective way to use the sensors
is with small groups of two or three. It is not practical for a large
number of children to crowd round an experiment.
Extra Adult Help
We found that it was useful to have another
adult around to work with groups. We set aside one morning a week to
allow different groups of children to work with the sensors at a time
when we knew extra help was available.
Staff Training
Time to allow the staff to be trained and
get familiar with using the equipment is essential.
Remember to keep the Datameter charged! This
is a simple task of plugging it into the mains - you do not need to
switch it on. It is a matter of getting into a routine so that it is
always ready for use.
Outline planning for Years 3 - 4
Pupils are taught in mixed year groups. Each group
began with a weekly half-hour lesson, although this was extended to
an hour when the experiments took place.
Week 1
Introduction
to the concept of how ICT can be used to control actions. We talked
about traffic lights, EPOS systems, car park barriers, etc. and then
discussed how computers can be used to assist these processes.
Discuss
sensors in the familiar environment, matching sensor to process (light
sensor to street lights, proximity sensors for some traffic light operations,
etc.).
EPOS
(Electronic Point of Sale) systems discussed and children asked to pay
attention to what happened the next time they paid for goods at the
supermarket.
Week 2
Introduce
the Datameter.
Give
pupils an opportunity to use all the sensors.
Use
the Datameter in real time (connected directly to the PC) so that the
pupils are immediately able to see the results in graphical format (using
Junior Insight software).
Make
sure children understand features of the graphs. Ask questions: Where
is there a rapid / slow change? Which are large / small changes?
Week 3
Using
the Datameter to measure how much light passes through different materials.
A cardboard box was provided. Children were given
the opportunity to discuss and decide in their groups how to carry out
the investigation.
The Datameter was attached to the PC throughout
the experiment. Children responded better to the immediate feedback
given with the graphing facility. The children put a hole in the box
which allowed the light sensor to be placed inside the box and the Datameter
outside. Groups decided to investigate the following:
Year
3 - how much light travels through different coloured paper
Year
4 - how much light travels through different materials
Week 4
Children
bring in different materials. (i.e. plastic, paper, card, tissue paper,
kitchen roll, etc.)
Provide
paper in different colours making sure there is a good variety of very
dark and very light papers.
Carry
out the tests using the Datameter
Prepare
spreadsheets of results.
Children were responsible for setting everything
up themselves. First, they checked that the Datameter was sending information
to the computer. They then replaced the box lid with different materials,
watching the changes in light readings as they changed the coloured
paper or material.
When we changed the material too quickly, the children
found it difficult to interpret the line graph. We therefore decided
to move from darkness (with the box lid on) to one material at a time.
It was now obvious where the change had taken place.
Each pair produced one chart showing the change
in light density from darkness for a particular colour or material.
This also enabled all children to take part in the experiment. The children
obtained printouts from the Junior Insight software and also used Excel
to prepare a spreadsheet showing their findings. Charts were also produced
from the spreadsheet, enabling the children to investigate different
chart types and the best ones to use to represent their findings to
best effect.
Week 5
Pupils
word process a project report.
Teacher
produces a display of work.
With
the class, interpret graphs and discuss findings.
Outline planning for Years 5 - 6
The first two weeks followed those for Years 3 -
4, allowing children to become familiar with the function and use of
sensors.
From the third week, pupils used the temperature
sensor to investigate how temperature varies from place to place in
a small area. This led to comparisons of local and global temperatures.
The differentiation was made in how the project was documented. Year
5 pupils compiled a Word report while Year 6 pupils created a PowerPoint
presentation.
Week 3
A group were given the Datameter with the temperature
sensor and asked to track temperature changes throughout a school day.
They were asked to choose 4 locations to measure the temperature (outside
the school buildings but within the grounds).
Week 4
Pupils
used the Datameter independently and uploaded the readings to the Junior
Insight software.
They
typed the readings onto an Excel spreadsheet.
With
help, they entered formulae to work out the lowest, highest and mean
readings.
They
produced charts in Excel and explore different chart types.
Literacy Links
The second part of the project for Years
5 and 6 involved the children sending Datameter to people in different
regions of the world to collect temperature data for the day that they
undertook their research. Replies were collected, and information put
into the spreadsheet for analysis and comparison.
Week 5
Year 5 wrote up the project using Word, while Year
6 prepared a simple PowerPoint presentation. All children contributed
to a display of the project.

Evaluation
Children enjoyed participating in these projects
and gained considerable ICT skills as part of the process. Since the
projects were set up to complement current curriculum subjects and topics,
pupils were able to assimilate the ICT skills within other areas of
study.
Both projects ran much more smoothly when children
were organised in groups of 2 or 3. It was very difficult for 6 or more
children to crowd around a Datameter and a cardboard box trying to see
readings (and blocking out the necessary daylight!).
Both staff and pupils feel a sense of purpose
and achievement. We have developed additional ICT skills that can be
used in the future. Many schools are in our situation, facing curriculum
demands which leave little time to develop other skills. Having made
the commitment to set aside extra time for staff training we feel it
has been time well spent.
