In the first half of today’s session we spoke about computer control.
Computer control is the transfer of data from a computer to a peripheral device
making it perform a specific procedure or routine.
Here are some examples…

Traffic

So…why do we use computers to control things?
· Accuracy- computers don’t
make mistakes- unless a human error has occurred.
· Consistency- a computer
can repeat the same operation over and over again.
· Computers never get tired
or lose concentration!
· Cheaper than employing
humans (Note: when working with KS2 you could discuss the impact this has had
on workers).
In the second half of our session we looked at programming and
monitoring and how they can be taught in the classroom as part of a very
practical lesson.
Programmable Toys
Bee-bots
A Bee-bot is a floor robot with a simple and child friendly layout that
is a perfect starting point for teaching control, directional language and
programming to young children. Children simply press the buttons to control how
many ‘steps’ forwards or backwards they want the bee-bot to take and to control
the direction it moves in. The fun is guessing how many steps the bee-bot needs
to make to reach a destination, but the trick is getting your head around how
many times it needs to turn to go in the direction you want it to move in. Once
you’ve finished programming simply press ‘Go’ and see what happens! Bee-bots
are great in foundation stage and KS1.
Pippins and
Pixies
Both pippins and pixies are programmable toys, just like the bee-bot,
except they require more complex commands and are therefore often more used in
KS2. Programming a pippin involves specifying the angle of the direction that
you want it to move in., you can also place a pen in the centre of a pippin and
programme it to draw a shape.
Flexiscope
A flexiscope is a microscope used in schools which is set up to
computer software allowing you to take pictures of what you are seeing. This
piece of equipment would be particularly beneficial in lessons like science and
means children can save images as evidence of the work that they have done and
to go alongside any written work about the objects they were examining.
Data-loggers
A data-logger is a device used to collect data which can then be
connected to a computer or SMART board and represented in a series of graphs
and tables. A data logger records changes in sound, temperature and light,
children can use it to investigate all types of things such as the amount of
traffic on their school road (by recording sound) and the different factors
which may affect this, such as changes in temperature which may equal more cars
on the road. I feel out of all the gadgets we tested today, the data logger
seems to open up the most amount of interesting ideas for possible lessons, and
the fact you can then evaluate the results so easily when connected to the computer,
is another plus side to this piece of equipment.
Workshop Activity- Pippin
1.
I would use the pippin to make cross circular
links between ICT and Numeracy by asking the children to programme their
equipment to draw a particular shape.
2.
The purpose of this activity would be to teach
new skills and to consolidate existing skills in both subjects.
3.
From an ICT
perspective, the purpose of the activity would be to improve children’s
programming skills which they are likely to have first developed in the early
stages of KS1 using bee-bots. The pippin would require the children to input
more complex commands thus extending their knowledge of programming. From a
mathematical perspective, the pippin would teach children the skill of
recognising which angle an object has to turn in order to move in a particular
direction. The pippin would also consolidate children’s existing knowledge on
shapes.
4.
The key vocabulary used in this activity would
be: pippin, degree, angle, 90 degrees, 180 degrees, 360 degrees, turn, left,
right (and any shapes the children wanted to draw).
5.
This activity could be extended for more able
children in the class by firstly specifying a complex shape to make the pippin
draw other than the standard square, after this the children could be given
some big card sectioned into squares, each with a letter from the alphabet, and
asked to spell out their name.
6.
This activity could be differentiated for less
able or younger children of the class by firstly giving them the task to follow
instructions to program the pippin move in a set of directions, and then
extending by asking them to try and draw a shape.
7.
There are opportunities to assess children’s
knowledge on directions, shapes, angles and programming, putting children in
small groups will show those who are more confident than others and this very
practical lesson means the teacher can walk around and monitor each group
easily.
8.
The nature of this activity would require a
lot of space- maybe floor space would be better than tables- but can be done in
a normal classroom, no real need for an ICT suite.
