Abstract
We rank students based on the amount of time they spend on an online homework module and then provide them with this information using a randomized experiment design. We then study how students respond to learning where they rank on this metric, which we take as a proxy for study effort, on subsequent study effort and course outcomes.

We rank students based on the amount of time they spend on an online homework module and then provide them with this information using a randomized experiment design. We then study how students respond to learning where they rank on this metric, which we take as a proxy for study effort, on subsequent study effort and course outcomes.

Primary Outcomes

Primary Outcomes (end points)
Time spent on online homeworks; homework scores; midterm and final exam performance; course grade
Primary Outcomes (explanation)
These are the ways that learning your effort rank will likely influence behavior.

Secondary Outcomes

Secondary Outcomes (end points)
We are interested in how these effects vary by different student characteristics, specifically; gender; low-income status; race/ethnicity; exam 1 performance; etc.
Secondary Outcomes (explanation)
We believe that there may be heterogeneous treatment effects across these student level dimensions.

Experimental Design

Experimental Design
We rank students based on the amount of time they spend on an online homework module and then provide them with this information using a randomized experiment design. We then study how students respond to learning where they rank on this metric, which we take as a proxy for study effort, on subsequent study effort and course outcomes. We plan to provide updated information in this same (randomized) way directly after each of the three course midterms.
