Studies have shown scholastic, creative, and social benefits of Montessori education, benefits that were hypothesized to result from better executive functioning on the part of those so educated. As these previous studies have not reported consistent outcomes supporting this idea, we therefore evaluated scholastic development in a cross-sectional study of kindergarten and elementary school-age students, with an emphasis on the three core executive measures of cognitive flexibility, working memory update, and selective attention (inhibition). Two hundred and one (201) children underwent a complete assessment: half of the participants were from Montessori settings, while the other half were controls from traditional schools. The results confirmed that Montessori participants outperformed peers from traditional schools both in academic outcomes and in creativity skills across age groups and in self-reported well-being at school at kindergarten age. No differences were found in global executive functions, except working memory. Moreover, a multiple mediations model revealed a significant impact of creative skills on academic outcomes influenced by the school experience. These results shed light on the possibly overestimated contribution of executive functions as the main contributor to scholastic success of Montessori students and call for further investigation. Here, we propose that Montessori school-age children benefit instead from a more balanced development stemming from self-directed creative execution.

Through performance monitoring individuals detect and learn from unexpected outcomes, indexed by post-error slowing and post-error improvement in accuracy. Though performance monitoring is essential for academic learning and improves across childhood, its susceptibility to educational influences has not been studied. Here we compared performance monitoring on a flanker task in 234 children aged 4 through 15, from traditional or Montessori classrooms.While traditional classrooms emphasize that students learn from teachers' feedback, Montessori classrooms encourage students to work independently with materials specially designed to support learners discovering errors for themselves. We found that Montessori students paused longer post-error in early childhood and, by adolescence, were more likely to self-correct. We also found that a developmental shift from longer to shorter pauses post-error being associated with self-correction happened younger in the Montessori group. Our findings
