Prime Online:

Teacher Professional Development for Inclusive Elementary Mathematics Classrooms

What is Prime Online?

Prime Online is a completely online professional development program designed to address 4th grade teachers’ (a) content knowledge for teaching mathematics, (b) understanding of the learning needs of students with learning disabilities and other struggling mathematics learners, and (c) knowledge of and skill in using mathematics evidence-based practices and progress monitoring within a model of classroom-based teacher inquiry. With funding from the Institute of Education Sciences in the U.S. Department of Education, we are conducting a research project to determine the effectiveness of the Prime Online professional development program. Given promising evidence gathered in an earlier pilot study, we will now explore whether Prime Online improves both teacher and student learning within school districts across Florida.


Who Can Participate?

Fourth-grade teachers with general and/or special education certification who teach the general education, grade-level, mathematics curriculum to students with and without learning disabilities and other struggling mathematics learners are being recruited to participate in the project.


When Does the Study Begin?

We will have two cohorts of teacher participants.

Cohort 1 will begin in May, 2019 and Cohort 2 will begin in April, 2020.

Note: We will not be starting the program again this April, 2020 as planned due to the COVID-19 pandemic. However, we continue to recruit teachers, so please do not hesitate to contact us with questions.


What Are The Benefits to Teachers?

All participating teachers will be paid for their participation, and receive an iPad, book, assessments, and both treatment and control teachers will eventually have access to the entire Prime Online program.
