Abstract
This paper reports on a strand of a larger investigation into the effect of metacognitive
training on 11 to 12-year-old students’ mathematical word problem solving in a cognitiveapprenticeship-
computer-based environment. Empirical results from the quasi-experimental
and case study designs suggested that treatment students outperformed control students on
the ability to solve word problems on their individual written measures and collaborative
“think aloud†interactions in a computer environment. Moreover, treatment students in the
case study elicited more well-regulated metacognitive decisions compared with control
students.
