Error Monitoring, a learning strategy designed to enable a student to detect and correct errors in written products, was taught to nine learning disabled (LD) adolescents. The instructional procedure involved an 11 step process including such procedures as describing the steps of the strategy, modeling the strategy, and student practice to criterion in both teacher generated and self generated passages. Results showed that students could detect and correct more errors after they received training. The error rate in their self generated products was especially low (close to zero) after training. Graphs of statistical data are offered, and monitoring strategy guidelines and record sheets are appended. (Author/SB)
