This study investigates the impact of adding an adaptive computer assisted instruction (CAI) program to current Head Start curriculum on low SES, African American pre-kindergarten students' reading and math gains. Students completed pre- and post-testing with a standardized reading and math measure in order to determine relative gains. The results show that students using the program had significant reading and math gains over those in the control group. These results suggest that an adaptive computer assisted instruction program can benefit pre-kindergarten students by developing early reading and math skills more effectively than in-class instruction alone.
