The study investigated the effects of mediated learning experience (MLE) intervention on Remedial school learners' cognitive functioning as measured by the Ravens Coloured Progressive Matrices (RCPM). The sample comprised 67 participants (males = 35; females = 32; mean age = 11.8) from Grade 4 through to Grade 7. Participants were given the RCPM on two occasions, and in-between, a non-randomly constituted experimental group was exposed to MLE intervention. Pre-post test results revealed significant improvement within the experimental group on the RCPM, while non-significant pre-post test results were found within the control group. These findings provide support for further development and application of dynamic assessment and its MLE construct. (Contains 1 table and 1 figure.)
