Problem solving is applicable to all grade levels and subject areas. This study focused on the development of problem-solving skills in fifth grade students using problem-solving software. A pre- and post-test were administered to 21 fifth grade students. Four students were chosen for the treatment group and four for the control group. The treatment group was given 7 weeks of instruction using problem-solving software appropriate for their age. Observations showed a positive change in all the treatment students' actions with and feelings toward computers and problem solving. Cognitive assessments were inconclusive. The appendix contains 20 lesson plans for the computer unit, strategies and difficulties with each of the software programs, and the pre-test and post-test designs used. (MKR)
