Abstract
Worldwide, pedagogical culture in schools is didactic, emphasizing one-way knowledge flows, limiting student learning. We study innovations at teacher training institutions in Uganda to reverse this towards a “culture of learning.” Teachers are trained to apply scientific approaches to improve their practice. A coordination structure generates spillovers to transform system-level practice. With these ingredients in place, change takes place through three steps. First, the initial training empowers teachers to use action-research to continuously improve their pedagogy, fostering dynamic, learner-centered, environments both inside and outside the classroom. Second, teachers form communities of practice, where collective reflection leads to a shared analysis of effective practices, enabling continuous improvement and adaptation. Finally, as communities grow and are coordinated by key actors, the program catalyzes a systemic shift, attracting untrained schools and teachers to participate. This embeds a culture of continuous learning that improves and grows independently, benefiting students on a larger scale. Our research seeks to understand how effects of this intervention, dubbed the "Learning to Learn" (LTL) approach, spread and sustain change over time. In this light, we ask: What density of teachers must be trained for effects to spread? How do the extent and speed of spillovers depend on a “coordinator”? What conditions cause a culture of learning to emerge, with dynamically increasing effects on learning? Our design involves randomizing characteristics of the implementation process at three levels: clusters (groups of schools), schools, and teachers. Answers will inform future scale-up plans beyond a single context, including how many teachers to target, what coordinating structures support impact, and conditions of long-lasting change.

Experimental Design

Experimental Design
In the first phase of the study, we will implement a cluster-randomized controlled trial (RCT) stratified at three levels. First, we will assign clusters of neighboring schools to high-density (75% of schools treated) or low-density (25% treated) areas. Second, within clusters, schools will be randomized into three groups: high-training (a majority of teachers trained per school), low-training (a minority of teachers trained per school), and no-training. Third, groups of teachers within schools will be randomly selected to attend the training.

In phase 2 of the study, a subset of clusters (both high- and low-density) will be randomly selected to invite a high-performing teacher to participate in a second year of training. In this second year, the teacher will be trained to coordinate and accompany action-research activities within the cluster of schools.

Experiment Characteristics

Sample size: planned number of clusters
Depending on funding, either ~200 schools (phase 1 only) or ~600 schools (both phase 1 and phase 2)
Sample size: planned number of observations
Depending on funding, between 200-700 pupils per school and roughly 11 teachers per school.
Sample size (or number of clusters) by treatment arms
Depending on funding, we will have 1/3 of clusters in high-density, 1/3 in low-density, and 1/3 in control. Within treated schools (within cluster), half of the treated schools will have high training and half will have low training.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
