MicroWorlds is a program that uses the Logo programming language, a dialect of Lisp programming language. It uses a turtle object which can be moved around, given commands, and eventually make shapes or even an animation.

It is part of a large set of dialects and implementations of Logo originating from the invention of Seymour Papert and aimed at triggering the development of abstract ideas by children through experimentation. As a tool for learning, Logo is flexible and provides immediate feedback; it is both accessible to young users and robust enough to create sophisticated projects. In original versions of Logo, Papert created a large 'turtle' that was programmed to move around the room by providing commands via the computer.

Syntax[edit]

The following is an example of something written in Logo:

Mac OS 10.7 or higher. MicroWorlds EX is a powerful Coding language that has been used by millions of kids worldwide. Download this trial version to code the projects in the Coding For Kids for Dummies book or the Getting Started with Coding book. Once downloaded, you can use this trial version for 35 days or 90 saves; whichever comes first.

In the example above, the user has gone into a part of the program called the procedure page, which allows for longer series of commands, and therefore more complex programs can be written. In this program, the cursor moves forward 90 units, turns left 90 degrees, right 180 degrees and then moves forward 4999 units.

Another example is:

In this example, the user makes a dialog box appear, having the text of whatever is inside the brackets. In this case, the box would have 'Hi!' written on it.

Commands can be written in one of two ways: using the procedures page or the command module. The command module allows for instructions to be executed immediately, whereas the procedures page holds instructions that are able to be referenced at any time (using the name written after the word 'to' at the beginning of a procedure).

Vocabulary[edit]

Logo is based on real words in its 'language' so that they are easy to remember. An example of this is the 'forward' command. 'Forward' can be used in a program such as this:

This simple line indicates that the turtle referred to before will move 50 units of computer screen in the direction it is pointed. The unit of measurement for 'forward' is one pixel on the screen. 'Forward' can also be abbreviated as the command 'fd', so therefore can be used like this:

Other important navigation commands include:

lt:x

turns the turtle left :x number of degrees

rt:x

turns the turtle right :x number of degrees

setpos [x y]

sets the position of the turtle in the coordinates of the screen, x being on the x axis, y on the y axis

pd

sets the turtle's 'pen' down, so that wherever it moves afterwards, it draws a line on the screen from where it started to where it ended up

pu

sets the turtle's 'pen' up, so that it does not draw a line anymore

setsh:x

changes the picture the turtle appears as to be a picture that is either drawn in Micro Worlds itself or imported into the program. :x refers to the shape's number

This is only a brief example of the hundreds of commands in Micro Worlds.

Versions[edit]

MicroWorlds EX is a powerful app that introduces coding to students in upper primary school and middle school. MicroWorlds has the ability to execute multiple tasks independently, also called parallel processing. Several processes can be launched independently which is very helpful when creating multiple character animations and simulations. Extra features in MicroWorlds, for example a text editor, shape centre, melody centre and the ability to import pictures all work with the Logo aspects to create multimedia projects, video games and simulations.

LCSI also provides MicroWorlds JR, an iconic version of Logo that allows younger children, who are non-readers, to learn to code.

Tom Walsh has written a school curriculum for MicroWorlds EX.^[1]

A self-study guide for use at home was written by Camille McCue.^[2]

MicroWorlds EX is available in many languages such as French, Spanish, Russian, Chinese, Portuguese, Italian, Armenian and Greek.

MicroWorlds is used as the main component of the curriculum used by OpenWorld Learning, an educational non-profit based in Denver, Colorado,^[3] that as of 2016 operated 11 elementary sites and three middle school sites in the Denver area. The organization provides a free after-school program to students interested in STEM (Science, Technology, Engineering and Math) education.

Microworlds EX can be used to make a variety of apps and interactive games.

If the turtle (your golf ball) falls into the water trap, you want your game to respond appropriately. You can make this happen by creating an on-color instruction. In MicroWorlds EX, you accomplish this by creating a command, and those are called Procedures. You put together Primitives to make Procedures, and you put together Procedures to make other Procedures.

Create a Water Trap Procedure so that when the turtle touches the blue field in your game, the Water Trap Procedure is executed. You also want to create a Win Procedure for when the turtle touches the black.

For your Water Trap Procedure, you want to hide the turtle so it looks like the ball has sunk. Then consider making an Announcement (some text to appear on screen when the player hits the water trap) so your player knows what happened, and insert a brief pause (as short as a tenth of a second, but as long as you wish) in the game so your player has time to see what’s happening and respond. Next, set the turtle back to the starting position.

For your Win Procedure, again you’ll want to hide the turtle and make a new Announcement, with another pause, and determine what happens next (for example, the game progresses to the next hole, or starts over if this is your only hole).

You can create a flag for your hole to make your game look more fun and realistic, and lastly, think about freezing the golf ball so that no player can just grab it and put it in the hole to cheat.
