CSUNny chatbot speeds registration but leaves persistence unchanged

In a four-year trial with 8,708 CSUN students from 2018, the CSUNny chatbot raised timely class registration by up to 34 percentage points but had no detectable effect on grades or persistence.

  • 1 for a person

    Reminders made students more likely to register for classes and Early Start by the deadlines studied, but credits, grades, persistence and graduation did not change.

Depth runs from 1, a convenience or time saved, to 5, a life or a livelihood preserved.

Compared with

Control-group students who received only the university's standard communications. Measured.

The system’s part
Not isolated. Students were randomly assigned to the chatbot or to the university's standard communications. The estimates cover the whole service, including campaigns written by staff and answers that staff supplied. The paper describes the AI as non-generative matching of questions to a knowledge base with a probability threshold. It does not describe the model.

    Students remain receptive over time, and impacts are concentrated in improved completion of time-sensitive administrative tasks, with no detectable effects on academic performance or persistence.

Details

AI system

Workflow

A chatbot team of CSUN staff and faculty wrote and sent the campaigns. Offices such as the registrar and financial aid supplied lists of students for targeted reminders. The chatbot answered questions that matched its knowledge base and flagged the rest for a staff member.

Follow-up

Conditions for replication

The task must be time-sensitive and required for continued enrollment, such as registering for classes. Campus offices must share student data so that targeted reminders reach the students who still need to act.

Purpose
