Establishing A Content Taxonomy For The Coherent Study Of Engineering In P-12 Schools, Greg Strimel, Tanner Huffman, Michael Grubbs, Eunhye Kim, Jamie Gurganus

Journal of Pre-College Engineering Education Research (J-PEER)

Engineering education has increasingly become an area of interest at the P-12 level, yet attempts to align engineering knowledge, skills, and habits to existing elementary and secondary educational programming have been parochial in nature (e.g., for a specific context, grade, or initiative). Consequently, a need exists to establish a coherent P-12 content framework for engineering teaching and learning, which would serve as both an epistemological foundation for the subject and a guide for the design of developmentally appropriate educational standards, performance expectations, learning progressions, and assessments. A comprehensive framework for P-12 engineering education would include a compelling rationale and vision …

The Critical Role Of Humidity In Modeling Summer Electricity Demand Across The United States, Debora Maia-Silva, Rohini Kumar, Roshanak Nateghi

School of Industrial Engineering Faculty Publications

Cooling demand is projected to increase under climate change. However, most of the existing projections are based on rising air temperatures alone, ignoring that rising temperatures are associated with increased humidity; a lethal combination that could significantly increase morbidity and mortality rates during extreme heat events. We bridge this gap by identifying the key measures of heat stress, considering both air temperature and near-surface humidity, in characterizing the climate sensitivity of electricity demand at a national scale. Here we show that in many of the high energy consuming states, such as California and Texas, projections based on air temperature alone …
