An Investigation of the Use of Computer-Aided-Instruction in Teaching Students How to Solve Selected Multistep General Chemistry Problems.
Grandey, Robert C.
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-reduction reactions. Emphasis was placed on developing computer routines which interpret student answers in their normal chemical form and tell the student what, if anything is wrong with them. Among the forms of answers for which routines were developed are labeled numerical answers, chemical formulas, and chemical equations. For each topic 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 by the students while using these lessons and by comparing the exam results for students who had computer-assisted lessons with those who did not.
