Since the 1960s, Logo was intended to have no threshold and no ceiling. It derives its magic from how little kids and graduate students find the same environment challenging, exciting and expressive. Although a variety of forces have conspired to make MicroWorlds use most common in years five through seven, little kids can use it in quite creative ways. Much has been written about how MicroWorlds can be used to enhance the learning of secondary school concepts. This column makes the case for using MicroWorlds in the lower primary grades.

A Great Value
Schools that own MicroWorlds site-licenses already have a “free” multimedia paint, animation, music and web-page creation software appropriate for young learners. There are many entry-points through which children may enter the world of MicroWorlds.

Painting the Picture
At its simplest level, MicroWorlds is a terrific paint program for little kids. It has everything but 100 ways to erase your creation. Kids can paint with the paint tools, stamp pre-defined shapes or create their own shapes to stamp. Make a new page, add a button to go to that page and create the next picture. Add a text box to the page and an illustrated story, poem or report is born. All of the techniques associated with process writing can be applied to the experience.

Painting a picture…

Click on the drawing centre to open the paint tools
Paint your picture
Hatch a turtle by clicking on the eye tool
Open the shapes centre to choose a “stamp”
Click once on the shape of your choice or double-click on a shape to edit it
Click on the turtle to change its shape
Choose the magnifying glass (+ or -) from the tool menu and then click on the turtle to change the size of the turtle
Choose the stamp icon from the tool menu and then click on the turtle to leave its fossil on the screen
Drag the turtle to another position and stamp it again (or change its shape)
Remember that there is still a “live” turtle on the screen so be sure to cut it with the scissors tool or hide it with HT

Can’t catch me! I’m the Gingerbread Man!

Creating multiple pages…

Choose Pages-New Page
Choose the button tool and click it on the screen in the position where you wish the button to appear
Type the name of the page you wish to turn to in the Instruction: line
Select Once

If you don’t like the appearance of MicroWorlds buttons, hatch a turtle, dress it in a great costume and make its instruction the name of the page you wish to turn to.

Put a transition on a page…

Choose Pages-Transition…
Select the transition you wish to use
Click OK

The transition will appear whenever this page loads.

Getting Moving

Why should little kids be limited to mindless drill or painting pictures? Even early readers can program MicroWorlds to perform simple animations. Write or print the names of simple turtle graphics commands (FD, BK, RT, LT, SETSH) with sample inputs on cards next to the computer. Names of the standard turtle shapes next to their pictures may also be placed on cards.

Baby animation…

Hatch a turtle
Turn it in the desired direction by clicking and dragging its nose
Open the shapes centre and select the shape you wish for the turtle to wear
Click on the turtle
Click the eye tool on the turtle to edit its instruction
Type the command, FD 5, in the Instruction: line
Select Many Times
Click on the turtle to make it go and repeat the process for additional turtles

Encourage kids to change the distance (number) by which the turtle goes forward and observe what happens.

Kids can even program colours to make a turtle reverse when it hits the brown mountain (see the MicroWorlds online help or users guide to learn how).

Toddler animation (flipbook animation)…
Follow the same steps as above, but add a command such as, SETSH [bird1 bird2] FD 5, in the Instruction: line of the turtle. These instructions may be written on student reference cards.

You can find out the name of turtle shapes by opening the shapes centre and holding the mouse over the shape (in Windows 95) or double-clicking on the shape (Macintosh).

Making Magic

Five year-old John Richardson uses MicroWorlds to tell stories, create insect reports and even design copies of his favorite commercial software products like The Logical Journey of the Zoombinis. Making software is not beyond the imagination of young kids. Why not make your LEGO rocket fly on the computer screen? In the past it was impossible for pre-readers to program computers.

Kids like John can hatch turtles, design turtle costumes, paint backgrounds, create multiple pages, compose music and record narration and sound effects without assistance. They can even create simple animations by typing the commands prepared on teacher-made reference cards.

After John creates all of his desired objects, he directs his Dad in how to program motion and interactivity. This process is quite similar to when pre-writers dictate a story to an older student or adult. However, a MicroWorlds project requires the use of mathematical processes, different senses and action.

The success of early-childhood MicroWorlds projects is dependent on three factors:

sufficient computer access
adult support
a great open-ended tool (MicroWorlds)

After little kids spend a few years “messing-about” with MicroWorlds they will have the fluency required to tackle more complex problem solving in specific school subjects. These children will appreciate the intellectual satisfaction and joy associated with teaching the computer to do something it may never have done before.
