Table 2_The role of intermediary representations in solving lever balance problems with different target representations and problem complexities.pdf

This study examined how intermediary representation use was associated with performance on lever balance problems and how this association varied across target representation types and problem complexity types.</p>Methods<p>A total of 130 ninth grade students solved 12 problems representing three target representation types and four problem complexity types.

Problem solving success was analyzed using a generalized linear mixed effects model.</p>Results<p>Intermediary representation use was associated with higher overall problem solving success. However, this association was strongest for mathematical and tabular target representations and more limited for diagrammatic target representations. The magnitude of the association also varied across problem complexity types.
