What happened
Coursemojo is a platform for middle school English language arts in which an assistant called Mojo works alongside the classroom teacher. Evidence for ESSA, the clearinghouse of the Center for Research and Reform in Education at Johns Hopkins University, rates it Moderate. The rating rests on two quasi-experimental studies from the 2024-25 school year. In a large Tennessee district, 2,045 sixth graders in twelve schools took part. Students using Coursemojo scored 8 points higher on the TCAP exam, an effect size of +0.12. In a large Texas district, over 3,000 sixth graders in twelve middle schools took part. There, 68% of Coursemojo students met the state passing benchmark on the STAAR reading test, against 59% of comparison students. The clearinghouse reports that results were stronger with use on 2.5 or more days a week. LXD Research conducted both studies, and the page does not say who paid for them. The maker says that OpenAI's GPT-4o model sorts each student's written answer against criteria written by its staff, and Mojo then asks a prewritten follow-up question.

When a student responds to an open-ended question, the OpenAI GPT-4o model analyzes their answer against specific, human authored criteria developed for that question.
Details
AI system
- Workflow
-
Each student used the platform on a personal device during English lessons. Mojo activities followed the district's chosen curriculum. Coursemojo trained teachers before launch and supported them during the year.
Follow-up
- Conditions for replication
-
Students use the platform consistently, about 2.5 or more days a week. The school uses a curriculum that Mojo's activities are built on.
