This study examined the effects of a WOE-based remote learning program for underachieving students on mathematical word problem solving. Three middle school students in the seventh grade were selected for their under achievements in math and participated in the WOE-based remote learning program, which was comprised of a total of 12 intervention sessions. The students' abilities to solve math word problems were measured 18 times throughout, baseline, intervention and maintence stages. The educational program for math word problems used in the study consisted of the self-regulated learning stage, in which students studied and solved problems for themselves by consulting WOEs that were fully presented, and the compensatory learning stage, in which they solved problems by consulting WOE where completion effects were applied and had a Q&A session with their teachers. The analysis results show that the three participants became proficient with the type of word problems in each session and improved their abilities to solve math word problems after the interventions. These findings demonstrate that a WOE-based remote learning program is effective for the proficiency of math word problems and ability of solving math word problems for underachieving middle school math students.
