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

The role of pedagogical agents in multimedia learning as an element that gives students social cues to promote cognition has been demonstrated in terms of enhancing students' academic performance and intrinsic motivation. Cognitive load is an important factor in measuring the effectiveness of multimedia learning, but the results of pedagogical agents' effects on learners' cognitive load have been consistently inconsistent. In this study, a meta-analytical approach was used to comprehensively analyse 24 empirical studies to investigate the effects of pedagogical agents on students' cognitive load in multimedia learning and the moderating factors in their process. The results showed that the teaching agent only slightly reduced the cognitive load. Moderating analyses show that the pedagogical agent appearance, pedagogical agent role, subject domain, form of media mix, intervention duration, and learning pace play a moderating role in the process of the pedagogical agent's influence on cognitive load, and can significantly reduce the cognitive load of learners.
