Engaging ALL Students in Engineering [PDF]

open access: yes2012 ASEE Annual Conference & Exposition Proceedings, 2020
Engaging ALL Students in EngineeringThe introduction of a “new” discipline—engineering—into K-12 education comes with bothopportunities and responsibilities. One opportunity is that, as a new discipline for this age level,relatively few entrenched ways of operating currently exist; there is room to start fresh with aneye toward best practices.
