Unlocking math potential in students from lower SES backgrounds - using instructional scaffolds to improve performance.
Article in NPJ science of learning, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Socioeconomic status (SES) influences school success. Students with lower SES may face challenges that this study aims to address through instructional scaffolding. To be effective, such support needs to consider students' individual strengths and weaknesses. In this study, 321 sixth-grade students used an e-textbook about fractions. They were randomly assigned to receive either adaptive task difficulty, explanatory feedback, or dynamic visualizations as scaffolds or no scaffolding. We assessed their fraction knowledge at pre- and post-test and eigth cognitive and motivational-affective characteristics. Latent profile analyses identified three profiles. Students with lower SES (below the nationwide average) are commonly associated with a profile that has unfavorable learning prerequisites. A linear mixed model revealed that adaptive task difficulty significantly benefited students in this profile. Implementing adaptive task difficulty in math classes might mitigate challenges associated with lower SES, enhancing educational success and equity by addressing individual prerequisites and learning needs.
