Description¶

Personality traits are relatively stable individual differences, most often measured on the Big Five dimensions. For learning, conscientiousness (being organised, persistent and self-controlled) is the trait most consistently associated with achievement, and openness (curiosity, breadth of interests) the second; agreeableness, extraversion and neuroticism show little association. Traits correlate with other variables here, such as self-regulation and need for cognition.

How strongly it relates to achievement¶

Mathematics. These are correlations across meta-analyses (Breit et al. 2025, a systematic review of 30 meta-analyses; overview [~W]): how strongly learners who differ on this characteristic differ in mathematics achievement, not how much changing it would change achievement. Many of these characteristics are correlated with one another, and the review is about mathematics only.

Conscientiousness r = .22, openness .13, agreeableness .01, extraversion −.02, neuroticism −.09. Claim [~W]

Implications¶

Context¶

Self-paced and online formats place more weight on conscientiousness-related behaviour, such as planning and keeping to a schedule.

Target Learners¶

Learners who struggle with planning and persistence.

Target Learning Objectives¶

Achievement, persistence and completion.

Intervention gains in conscientiousness were generally maintained at follow-up, but mediation was never tested and only one intervention examined moderation [+W] — instruction changes it
Learning patterns are associated with personal factors (personality, motivation, beliefs, prior education, age, gender); their associations with personality are weak to moderate, indicating learning patterns are not stable traits [+W] — learners who differ on it differ in outcomes
