This practicum describes a computer assisted instructional (CAI) program written in the computer language BASIC. This computer program was designed to help 11th and 12th grade algebra students (n=15) better understand the concept of linear equations. The program has three sections: the first is a tutorial, the second section gives the student the opportunity to answer questions on linear equations with immediate feedback, and the last section is a test. With this CAI program, teachers will have an alternative method of teaching algebra other than with a textbook and chalkboard. After 4 weeks of use, students in the target group showed significant gains in their abilities to write linear equations. Included in this study are the purpose, research and solution strategy, methodology, results as well as a copy of an attitudinal survey, and recommendations. Appended are test results from the district, school, and classroom, copy of the pretest and posttest, instructions for utilizing the CAI program, and a flowchart of the program. (Author/KR)
