How do we design and scale STEM courses in a way that values diversity, equity, inclusion, and accessibility? First, Dr. Manisha Sharan shares how linguistic diversity impacts STEM teaching and learning in higher education. Dr. Sharan will share strategies and scaffolding for educators, curriculum developers, and institutional leaders to help linguistically diverse students succeed in STEM. Then, Dr. Vandana Janeja discusses the growing demand for data science skills and the challenges of scaling data science courses and curriculum throughout STEM, particularly at resource-constrained institutions. In this presentation, Dr. Janeja will share approaches for meeting these challenges in a way that prioritizes diversity, equity, and inclusion.
