Normally achieving, learning-disabled and mildly retarded students (n=148, ages 6-9) were trained to select the odd picture of a 3-picture array. Mildly retarded subjects showed large, consistent performance differences from the other groups, but learning-disabled subjects could not effectively be distinguished from normally achieving peers.…

This study examined the arithmetic computation performance of 229 normally achieving students (ages 9 to 14) and 101 students with learning disabilities. Results found that the students with learning disabilities performed at lower levels and that their progress from one age to another was extremely limited. (Author/CR)

Nineteen special educators implemented Curriculum-Based Measurement with a total of 36 learning-disabled math pupils in grades 2-8 to examine the effects of goal line feedback. Results indicated comparable levels and slopes of student performance across treatment conditions, although goal line feedback was associated with greater performance…
