Primary Outcomes (explanation)
We use validated psychometric scales to measure students and teachers’ well-being (MBI, BAT). We measure teachers’ sense of community through their participation in coffee gatherings we organize in treated and control schools, and via answers to open-ended survey questions (i.e., “what is your definition of working community?”).
We measure teachers/students cooperation through a behavioural task: we distribute half of lottery tickets to teacher/student pairs. The lottery tickets display a barcode with no digits. Teachers and students need to cooperate to match the missing half in order to participate in the lottery. We compare the share of matched tickets in treated vs control schools. We also track noise dynamics in three random lectures to see whether the intervention affected conflictuality in the classroom, as suggested by smoother noise dynamics.
We rely on students’ grades and their performance on a sample of questions from a standardized test to measure students’ outcomes.
We will collect three types of data: survey, observational and administrative data.
i) Survey Data: We will interview teachers, students, and schools’ principals at baseline (September 2023) and endline (May 2024), through tablet-based questionnaires.
ii) Observational Data: We will: a) collect teachers’ mood via monthly SMS; b) collect teachers’ attendance to social events organized at baseline and follow-up; c) observe students' and teachers’ cooperation in games; d) measure decibels in classrooms via noise detectors; e) use qualitative data psychologists collect during the intervention.
iii) Administrative Data: Students’ grades and attendance, high school choice (8th-graders only).
