內容介紹：
Education technology (EdTech) companies are altering the education landscape. In this paper, we study DonorsChoose, a nonprofit that operates a teacher crowdfunding platform. Given the K--12 system is hard to improve, we ask whether DonorsChoose moves the needle on effectiveness and inequality. Combining DonorsChoose data with data on student test scores in Pennsylvania from 2012--2013 to 2017--2018, we find an increase in the number of DonorsChoose projects funded at a school leads to higher student performance, after controlling for selection biases. For a school with zero project, one funded project (about $400 in value) achieves about 2 to 9 additional students, on average, scoring at the basic and above on all tested subjects in high school and on science and ELA in primary and middle schools. These effects are driven primarily by teacher projects from the lowest income schools. Based on a textual analysis of over 20 thousands of statements from all funded teachers describing how resources are used, we find two channels of improvement most effective in the lowest income schools. Our study suggests that those in the education sector can harness the wisdom of frontline workers -- teachers -- to improve effectiveness and equity.
