Collaborative philosophical enquiry for school children: cognitive effects at 10-12 years

Area of Science:

• Cognitive development
• Educational psychology
• Intervention studies

Background:

• The modifiability of cognitive ability is a key debate in education.
• Previous 'thinking skills' interventions show promise but lack exploration of generalized effects.

Purpose of the Study:

• To investigate if a collaborative, interactive dialogue intervention enhances cognitive abilities.
• To assess the generalization of intervention effects to non-verbal and quantitative reasoning.

Main Methods:

• A 16-month collaborative inquiry intervention for 105 children (aged 10) in four classes/schools.
• A control group (N=72) followed a standard curriculum.
• Cognitive Abilities Test administered pre- and post-intervention.

Main Results:

• Intervention group showed significant gains in verbal, non-verbal, and quantitative reasoning.
• Gains were consistent across schools and observed in both boys and girls.
• Students with higher pre-test abilities showed smaller gains; controls showed no gains.

Conclusions:

• Philosophical inquiry via interactive dialogue enhances cognitive abilities and generalizes reasoning skills.
• Intervention effects were robust across schools, genders, and abilities.
• This large-scale trial demonstrated substantial effect sizes, exceeding prior literature.
