title: The differential effects of teaching addition through strategy instruction versus drill and practice to students with and without learning disabilities.
abstract: Forty-two second-grade general education students and 42 students with learning disabilities (LD) were taught basic, one-digit addition facts (e.g., 5 + 3 = _). Students received instruction via (a) a minimum addend strategy, (b) drill and practice, or (c) control. The effectiveness of the two methods was measured through students' accuracy and latency scores on a posttest and a transfer task (e.g., 5 + 3 + 7 =_). Students with LD improved significantly only in the strategy condition, as compared to drill-and-practice and control conditions, whereas general education students improved significantly both in the strategy and the drill-and-practice conditions as compared to the control condition. However, in the transfer task, students from all groups became significantly more accurate only in the strategy condition, while all students were significantly faster than their control group peers regardless of teaching method. The implications for teachers' differential choices of methods of instruction for students with different learning characteristics are discussed.
