Computerized dynamic assessment of seriational thinking modifiability: Effects of mediation on seriation and readiness for math among kindergarten and grade 1 children.
Trial report in The British journal of educational psychology, 2026. 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
BACKGROUND AND
aimsA vast body of theory and research highlights the operation of seriation as a prerequisite to mathematical thinking in young children. However, there is limited evidence that seriation interventions improve early years mathematics. The current study's primary aim was to explore whether a brief computerized intervention for seriation within a dynamic assessment procedure can enhance seriation and transfer to mathematics readiness, the effect of intervention on task dimensions of quantity, size and darkness, and the prediction of math modifiability by seriational modifiability. SAMPLE: A sample of 440 Kindergarten and Grade 1 children was randomly assigned to experimental (n = 231) and control groups (n = 209). The mean age (in months) of the children in the experimental and control groups was 73.48 and 74.51, respectively. The number of boys and girls was 228 and 212, respectively.
methodsAll children were administered a computerized version of the Children's Seriational Thinking Modifiability Test and the Math Readiness Test before and after the intervention. The experimental group of children received 45 min of mediation on seriation problems, whereas the control group practised seriation problems without mediation.
resultsThe findings revealed that children in the experimental group demonstrated improved seriation and math performance compared to children in the control group. More significant increases were observed in size and darkness than in quantity. Seriational modifiability significantly predicted readiness for math improvement. The findings support our hypothesis that seriation intervention is essential for developing math thinking.
