Subclaims¶

q3 i? Tools 5-year-olds outperformed control children on both EF measures taxing all 3 core EFs, especially on the more EF-demanding conditions. → Diamond Adele 2011 q3 i? Montessori children chosen by lottery showed better EFs, reading, and math at age 5 and more creativity in essay writing at age 12 than lottery peers not chosen. → Diamond Adele 2011 (2)

q3 · i? · review · r2

The review reports Tools was evaluated against another high-quality program using EF measures requiring transfer of training; benefits required EF supports interwoven into all academic activities all day.

"Tools 5-year-olds outperformed control children on both EF measures, which taxed all 3 core EFs, and especially on the more EF-demanding conditions. Thus the program with more play produced better EFs than the one with more direct instruction."

q3 · i? · review · r3

The review reports a lottery-based comparison of children entering an AMI-approved Montessori public school versus lottery peers, assessed at end of Kindergarten and end of Grade 6.

"At age 5, Montessori children showed better EFs than peers attending other schools. They performed better in reading and math and showed more concern for fairness and justice. No group difference was found in delay of gratification."

Discussion¶

Related Claims¶

• Largest EF-training benefits emerge on the most demanding EF tasks and task conditions, so outcome measures must test the limits of children's EF abilities — a broader claim this one bears on
• Curriculum add-ons PATHS and CSRP improve children's EFs and related outcomes in regular classrooms, with CSRP's academic gains mediated largely via EF improvement — a narrower finding that bears on this claim
• Low-income children in high-fidelity Montessori significantly closed the achievement gap with higher-income children by the end of a longitudinal lottery study — related
• Implementation fidelity matters: classrooms using only Montessori materials produced greater gains than classrooms mixing in other materials — related
• Children admitted by random lottery to high-fidelity Montessori schools performed better or the same as waitlisted controls on academic, executive function, and social measures, never worse — related
• Isolated EF interventions show robust near-term EF gains but poor transfer, including to early mathematics — related
• Mindfulness interventions show comparatively robust efficacy for preschool SR/EF, especially for outcomes requiring integrated mobilisation of EFs and SR — related
• Children attending alternative schools (Montessori, Steiner) outperform mainstream-school children on figural divergent and convergent thinking measures — related
