HOW TO USE IT
The setup button generates two random unsigned binary numbers.The slow-motion slider is an easy way to adjust the speed of the display. Set it to zero if you want to show the final result as quickly as possible. 0.4 is a good setting for most purposes.
The step button demonstrates the next step, and then stops so you can take notes. This is useful when you are first learning the method.
The go button does each remaining step, at a speed determined by the slow-motion slider. This is useful when you do not need to take notes between each step. If you want to pause the demonstration, click the go button a second time and it will stop after finishing the current step.
The quiz button generates a random multiplication problem and then asks you for the product.
The show-again button starts the same multiplication problem from the beginning. This is very useful when your hand-calculations do not agree with the model's calculations.
HomeApplets on this website were written by Teresa Carrigan in 2004, for use in computer science courses at Blackburn College, with the exception of the Fireworks applet. The applets made with NetLogo require Java 1.4.1 or higher to run. The applets made with NetBeans require Java 1.4.2 or higher to run. Applets might not run on Windows 95 or Mac OS 8 or 9. You may obtain the latest Java plugin from Sun's Java site.
