Instructor articulated how s/he proactively supports a wide range of learning styles and abilities of all students, as opposed to just making reactive accommodations for those with registered disabilities. Note: This support does not entail sacrificing academic rigor or student learning outcomes. The goal is supporting the needs of all learners as opposed to having an inflexible teaching and learning process.
