1 · What the graph read from it

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.

2 · The registry

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

Fractions knowledge is widely recognized as a key building block for developing mathematical competence. However, many children face difficulties learning fractions. Recognizing these challenges, researchers have sought potential leverage points to enhance children's fraction learning. In the present study, we investigated the relative contributions of verbal skills vs. non-verbal, non-symbolic number processing to 5th- to 7th- grade children's fractions skills. Specifically, we compared two math-specific verbal skills-transcoding and mathematics vocabulary-and two skills representing non-symbolic analog magnitudes-approximate number sense acuity and acuity for processing non-symbolic ratios. To assess children's symbolic fraction abilities, we used an experimental fraction arithmetic error detection task alongside a fraction magnitude comparison task, with fractions stimuli composed of two-digit components. Critically, mathematics vocabulary was the only predictor of interest that significantly predicted performance on both the error detection and comparison tasks. Our findings underscore the importance of math-specific verbal skills in supporting children's fraction abilities, perhaps implicating their role in fostering conceptual understanding, while indicating a limited role for analog representational skills.
