• Student time investment
• Student learning (performance on math and Bangla questions)
• Student engagement and re-enrollment

Experimental Design (Public)
|
Before
Our sample consists of households that have (a) at least one child in grades 6-10 (grades 7-11 in January 2021) and (b) have at least one smartphone in the house. The entire sample was cross-randomized in evenly sized cells across Treatment 1 (information and reminders about remote TV lessons and online platforms) and Treatment 2 (adaptive learning).
Treatment arm 3 (data subsidy) is cross randomized equally across Treatments 2 and/or 1b (TV + internet). Treatment arm 4 (teacher support) was initially cross-randomized to 1/4 of students (teacher support) across Treatments 1a and 1b (TV only and TV + internet only), though we increased the share assigned to treatment in response to substantial treatment attrition.
Our main empirical specifications will estimate intention-to-treat effects, reflecting the causal impact of assignment to each treatment arm on our outcomes of interest.

After
Our baseline sample consists of 7,576 households that have (a) at least one child in grades 6-10 (grades 7-11 in January 2021) and (b) have at least one smartphone in the house. The entire sample was cross-randomized in evenly sized cells across Treatment 1 (information and reminders about remote TV lessons and online platforms) and Treatment 2 (adaptive learning). 6,746 households agreed to be recontacted and form the sample for our midline and endline surveys.
Treatment arm 3 (data subsidy) is cross randomized equally across Treatments 2 and/or 1b (TV + internet). Treatment arm 4 (teacher support) was initially cross-randomized to 1/4 of students (teacher support) across Treatments 1a and 1b (TV only and TV + internet only), though we increased the share assigned to treatment in response to substantial treatment attrition.
Our main empirical specifications will estimate intention-to-treat effects, reflecting the causal impact of assignment to each treatment arm on our outcomes of interest.

Sample size (or number of clusters) by treatment arms
|
Before
Equal size treatment arms across the main two groups:
- No outreach, no encouragement (control): 22,500
- Encouragement, no outreach to teachers: 22,500
- Outreach to teachers, no encouragement: 22,500
- Outreach to teachers, encouragement: 22,500
Within the encouragement treatment arm (45,000 treated), we will randomly assign students to the three types of information if their household has access to a smartphone and cable television. We do not know in advance what this sample size will be, but the treatment assignment will be distributed evenly (1/3, 1/3, 1/3) for that group. If 80% of households have access to a smartphone and cable television (36,000), then the sample size for treatment arms 2a, 2b, and 2c will be 12,000 each.
Data package reduction: The exact sample size of the data reduction package treatment arm will depend on budgetary constraints, but the randomization strategy is the following:
- Take the sample of 45,000 assigned to encouragement treatment
- Restrict to those who have access to a smart phone and are subscribers of our telecom partner
- Exclude treatment 2a (information about TV only)
- Among those, randomly select X to receive the data package subsidy, and the remainder will not receive the subsidy.
Most outcomes will be collected by IVR for the full sample. Outcomes requiring in-person phone survey (such as expectations, aspirations, and mental health outcomes) will be only collected for a subsample of individuals (around 10,000).

After
Below, we provide an exhaustive list of treatment arms that arise from cross-randomizing each of the main treatment arms.
• 0. Control : 1,894
• 1a. TV : 525
• 1b. TV + internet : 253
• 2a. Adaptive learning : 947
• 2b. Adaptive learning + TV : 471
• 2c. Adaptive learning + TV + internet : 473
• 3a. Data subsidy + TV + internet : 288
• 3b. Data subsidy + Adaptive learning : 947
• 3c. Data subsidy + Adaptive learning + TV : 476
• 3d. Data subsidy + Adaptive learning + TV + internet : 474
• 4a. Teacher support + TV : 422
• 4b. Teacher support + TV + internet : 223
• 4c. Teacher support + Data subsidy + TV + internet : 183
