Experimental Design
Experimental Design
This study will examine the effects of tracking students within economics courses via a randomized controlled trial (RCT).
Experimental Design Details
Students who would have been assigned a section of SS251 within an hour will be randomly assigned to one of the sections of SS201 offered in the same hour (time slot). If there are are fewer than 9 SS251 students within an hour, they will all be assigned the same randomly selected section. If there are more than 8 but fewer than 17 within an hour, the SS251 students will be equally and randomly split between two sections within the hour, and so on. SS201 students within an hour will then be randomly assigned to fill in a section with or without SS251 students. At the conclusion of the semester, we will analyze how assignment to a section with SS251 students affects SS201 student's performance, major choice, and other taste and academic outcomes.
Randomization Method
randomization done in office by a computer
Randomization Unit
cluster of randomization is classroom
Was the treatment clustered?
Yes
Experiment Characteristics
Sample size: planned number of clusters
70 classrooms
Sample size: planned number of observations
1100
Sample size (or number of clusters) by treatment arms
17 treatment classrooms, 53 control classroom
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Assuming an intraclass correlation in grades and major choice of 0.03, we estimate being able to detect a 0.1 grade point change in performance and a 3.3 percentage point increase in probability of majoring in economics (with power of 0.8)
