Abstract: A method of using a computer to teach, wherein a child first studies a first element of information located on a computer screen, then locates an empty space adjacent to first element. The empty space is intended to receive a second related element of information. After comparing what is available from a group of second elements, the child selects an appropriate second element from a remote source located on the screen. Once a correct second element is chosen, appropriate software allows the child to computer activate (touch screen or use a mouse) to selectively display a third element. The third element relates to the second element, while the second element relates to the first. The child learns by observing the designed relationship between any first element and the second element and any relationship between the second element and the third element.
