Does the "Tools of the Mind" curriculum help kids self-regulate?
The Tools of the Mind curriculum did not improve self-regulation overall, but it did benefit children who started the study with high levels of hyperactivity and inattention.

What they did
Researchers conducted a study lasting about 15 months, assigning 20 childcare sites to either the highly structured Tools of the Mind curriculum or a child-centered, play-based program. They evaluated children's self-regulation and executive function across multiple time points using behavioral tasks, vocabulary tests, and teacher-and-parent questionnaires. The researchers focused on whether children's initial language skills or hyperactivity levels influenced how much they benefited from each program.
What they found
There was no overall difference in self-regulation or executive function improvements between children in the two curricula. However, children who initially scored high in hyperactivity and inattention showed significantly greater gains on a behavioral executive function task when enrolled in the Tools of the Mind curriculum. This moderation effect was visible when scoring the task using a simplified correct-or-incorrect method, but was not statistically significant under traditional scoring.
The limits
What it doesn't show
The study experienced substantial attrition during the summer, meaning a large portion of the original cohort did not complete the final assessments. Because individual socioeconomic data were unavailable, the researchers could not directly evaluate if family income moderated the curriculum's effects. Additionally, while teachers in the intervention classrooms implemented the core elements of the new curriculum moderately well, they struggled to introduce the more advanced program elements by the end of the study.
Key terms
- Executive function
- A set of top-down cognitive processes—including working memory, inhibitory control, and cognitive flexibility—that enable goal-directed behavior.
- Self-regulation
- The behavioral ability to monitor and manage one's energy states, emotions, thoughts, and attention in ways that are acceptable and produce positive results.
- Cluster-randomized controlled trial
- A study design where pre-existing groups of individuals, such as classrooms or schools, rather than the individuals themselves, are randomly assigned to treatment conditions.
- Scaffolding
- A teaching method that offers temporary support to students as they learn new concepts, which is gradually removed as they gain independence.
- Intent-to-treat analysis
- An analytical approach where all participants who were randomized are included in the final analysis, regardless of whether they dropped out or completed the intervention.

Common questions
Why didn't the study find an overall benefit for all children using the Tools of the Mind curriculum?
The comparison curriculum, Playing to Learn, is also a high-quality, play-based program. Since both curricula encourage active play and social interaction, they may both naturally support self-regulation, leaving little room for Tools of the Mind to show a distinct advantage for typically developing children.
How did the researchers measure the teachers' implementation of the curriculum?
They created a specialized checklist of core activities and sent independent observers to watch classroom activities at multiple intervals during the year, ensuring the curriculum was being used as intended.
Why did so many children drop out of the study?
The dropouts were largely due to the concurrent rollout of a free, full-day kindergarten program in Ontario, which led parents to pull their children out of the paid childcare centers where the study was taking place.
What is the practical takeaway of these findings for educators?
Highly structured, self-regulation-focused curricula may be particularly useful when targeted toward children who struggle most with hyperactivity and inattention, rather than being applied universally.
