Students are dropping out of high school at an increasing rate. Many students have dropped out because they have poor basic skills and therefore cannot succeed academically. This study developed a strategy whereby the classroom teacher was given the responsibility to manage all aspects of the instructional process, including the assignment of computer-based learning activities for low achieving At-Risk students and peer group learning. The research investigated the effectiveness of a computer-based instructional model for improving the ability of At-Risk students to read, write, and calculate. The model placed the microcomputer and related software in the hands of the classroom teacher to be used as a tool for the target students in grades 1–8. Besides increased performance in most grade level tests, students and teachers also demonstrate positive attitudes toward using computers as tools.
