Four new Project Solo modules are presented. A module on computer graphing with an x-y plotter explains the format for input to the computer, demonstrates the effect of scaling, and gives several on-line exercises to produce graphs. Several student-written programs in elementary and advanced mathematics, French, and U.S. history show how peer teaching can be accomplished with a computer. Four computer games are presented: hide-and-seek, NIM, MODULO, and space war. Four simulations--lunar landing module, crazy eights, rectangular billiards, and eliptical billiards--are also offered.
