About identification and remediation of systematic error patterns in subtraction. Study investigated 90 elementary teacher's ability to identify two systematic error patterns in subtration and than prescribe an instructions focus.
Educators typically analyze students' mathematical errors with the intent to improve instruction and correct misconceptions.Evaluating students' work to determine an appropriate instructional focus to correct errors is one of the main tenets of remedial or corrective education for all students, but especially for students with LD and low-performing students. Identification and analysis of students' arithmetic errors has the potential to improve instructional planning and, ultimately, student performance.
Although educators and researchers debate the numerous types of errors and their causes, as well as instructional approaches and procedures to correct errors, extensive research, including computer analysis of students' work , indicates that large majorities of students' errors are consistent and systematic.
Subtraction is particularly problematic for many students. Several researchers report that students experience difficulty with problems requiring borrowing.
