Lumen’s new Introductory to Statistics course will be delivered in Lumen One, a new platform that brings together the best of Lumen’s teaching & learning solutions including a full suite of professional development resources to support evidence-based teaching. Designed for the Introductory Statistics course, it can also be used in a co-requisite course model, as it includes extensive additional support for those students struggling with prerequisite skills.
Designed to Support Equity
This Introductory Statistics course is built with support from the Bill & Melinda Gates Foundation to promote equitable outcomes in gateway courses. Putting equity at the center of course design allows us to focus on the research-backed practices and approaches that have a real and measurable positive impact on outcomes for all students, especially Black, Latino/a/x, Indigenous, and low-income students.
The platform and content of the course are built to:
- Create and foster connections between faculty and students.
- Support students’ sense of belonging and engagement.
- Provide early & timely intervention when students face challenges.
- Surface student performance and actionable data for faculty to quickly see who’s struggling and help them.
- Include sample data sets and problems that are relevant and culturally diverse.
- Provide worked problem videos that make students feel represented and included.
Working closely with both student and faculty groups, Lumen’s principles of co-design and collaboration also extend to the course content, which comes from our partnership with The Dana Center at UT Austin.
Key features include:
- A simplified, highly-actionable Faculty Engagement Center that enables timely intervention when students are struggling
- Class-wide performance analytics on pre-requisite skills and learning objectives so you can flex your instruction to better support your students
- A suite of support resources, including evidence-based teaching practices to help faculty quickly identify and action student support needs
- Facilitation of peer-to-peer learning and engagement
- A design that is built from the ground up to promote equitable outcomes through research-backed instruction
