PS2206 INFO & COMMUNICATION TECHNOLOGY IN SCIENCE & MATHS THE USE OF PC LOGO WITH UPPER PRIMARY PUPIL Aims: 

Pupils should be able to use the basic commands for examples: fd, rt and lt correctly.



Pupils should be able to draw shapes by using logo programming correctly.

In order to try out this program, I chose one year 5 pupil in my previous school, Sekolah Rendah Hj Tarif, Kg Tamoi Tengah. She only has basic knowledge about computer and does not have computer at home. First, I introduced the program by showing her of how to draw rectangle. I asked her to observe the basic commands used to draw the rectangle. She noticed the term fd, rt and lt and was able to explain at me the meaning and uses of the term. When the pupil gets familiar with the program, I asked her to draw a square. She realized that square have 4 equal sides and the following are the steps used by the pupil to draw a square by using pc logo. fd 180 rt 90 fd 180 rt 90 fd 180 rt 90 fd 180

Next, I asked her to draw a rectangle. Even though, I have showed her the example of rectangle before but she has difficulties in this task. She was not confident with the steps taken to draw a rectangle because it has different sides. In this part, I gave her some hints by helping her reviewing previous lesson on shapes i.e. rectangle. She managed to answer me that rectangle has 2 lengths and 2 breadths which mean that she have to use 2 different numbers to draw rectangle. The following are the steps used by the pupil to draw rectangle. fd 100 rt 90 fd 200 rt 90 fd 100 rt 90 fd 200 Finally, I introduced the term repeat to the pupil. By showing her an example on square (repeat 4 [fd 80 rt 90]), I let her to explore any shapes she likes and at the end she was able to give me square, rectangle, octagon and decagon. Here are the shapes which were done by the pupil.

repeat 4 [fd 150 lt 90]

repeat 4 [fd 80 lt 90 fd 190 lt 90]

repeat 8 [fd 100 lt 45]

repeat 10 [fd 130 lt 45]

As a conclusion, at the beginning, pupil tends to have difficulties in using this program. Therefore, I have to give hints of how to use the term fd, rt, lt and repeat in using the logo programming.

However, when the pupil gets familiar

with the use of the commands, she was able to draw the shapes of different sizes. From the interview, the pupil told me that it was difficult to use the commands at first. But by doing a lot of practice, it is easy to run the program. She also found out that the use of repeat is easier compare to the long steps taken to draw the shapes.
