Abstract
We conduct an adaptive experiment to select one out of six treatment arms of biweekly phone calls to parents that deliver reading exercises for first graders. The experiment is carried out in two waves - start to midterm, and midterm to endterm - during term 3 of the first grade in a sample of 108 private primary schools in Kenya. The method uses Bayesian econometrics to estimate average treatment effects and exploration sampling (Kasy and Sautmann, 2021) to assign parents to treatment arms in each wave. The objective is to identify the treatment arm with the highest average "correct words per minute" (cwpm) score.

Experimental Details

Interventions

Intervention(s)
We carry out 3 methods of leveling reading exercises by students' reading proficiency, and 2 different delivery formats (either instructing parents how to tutor children, or the IVR tutoring the reading exercises directly), for a total of 3x2 = 6 treatment arms.

Experimental Design

Experimental Design
We carry out an adaptive experiment with 6 treatment arms and a control group to identify the treatment arm that in expectation leads to the greatest improvements in reading fluency, through engaging parents in reading regularly with their children at home. In the first wave of the experiment, student IDs are randomly assigned to each arm and the control; in the second wave, we calculate the probability that each treatment arm is optimal using Bayesian estimation and then use Exploration Sampling (Kasy and Sautmann, 2021) to assign the wave-2 sample to these arms.
