The development of computer-assisted instructional lessons on the following three topics is discussed: 1) the mole concept and chemical formulas, 2) concentration of solutions and quantities from chemical equations, and 3) balancing equations for oxidation-reductioh reactions. Emphasis was placed on developing computer routines which interpret student answers in theix normal chemical form and tell the student wh,t, if anything is wrong with them. Among the forms of answers for which routines were developed are labeled numericEll answers, chemical formulas, and chemical equations. For each (2.p1c lessons were developed in each of the following three styles: 1) instructional sequences, 2) practice problems, and 3) quizzes with forced review of week areas. The combination of the three lesson styles was successful in providing each individual student with a unique educational experience. The effectiveness of these lessons was determined by analyzing the data generated bv the students while using these lessons and by comparing the exam results for students who had computer-assisted lessons with those who did not.
