Experimental Design (Public)
|
Before
In 2014-2015, the relative merit-based and merit-based scholarships were randomized across 118 grades (5-8) within 31 schools. The feedback was randomized individually to half of the students within these schools and grades. The grades were assigned as follows:
Group 1 (46 grades): Merit-based scholarship based on final exam rank, feedback of the midterm exam rank given to half of the students.
Group 2 (42 grades): Relative merit-based scholarship based on final exam rank, feedback of the midterm exam rank given to half of the students.
Group 3 (40 grades): No scholarship, feedback of the midterm exam rank given to half of the students.
In 2016, 122 grades (4-7) in 31 schools are randomized as follows:
Group 1 (21 grades): No scholarship, no tutoring
Group 2 (40 grades): No scholarship, tutoring randomly assigned to half of students
Group 3 (21 grades): Scholarship, no tutoring
Group 4 (40 grades): Scholarship, tutoring randomly assigned to half of students
Students eligible for tutoring will be randomly assigned to tutoring groups of sizes of 4, 6, 8, or 10.
