New Report Highlights Key Findings from Next Generation STEM Schools Forum
In the 2015 State of the Union address, President Obama called for Next Generation High Schools. Next Generation STEM schools seek to intensify Science, Technology, Engineering and Math (STEM) opportunities, especially for historically underrepresented students. Such schools aim to strengthen STEM learning for all students who have a strong interest in STEM, regardless of their…

Playing the Long Game: Utah Renews Investment in its Innovation Ecosystem
Innovation—the process of creating new products and services and delivering them to customers—is tough. It’s tough, because the innovation process is nonlinear, requires adaptation, requires multiple skillsets, and engaging multiple stakeholders. Regions with strong innovation systems are well known, but where do states trying to build innovation systems start? Utah offers some good lessons. In…

Characteristics of Successful Inclusive STEM High Schools and their Impact on Student Outcomes
There has been a growing interest across the U.S. in expanding science, technology, engineering and math (STEM) opportunities for our nation’s youth through STEM-focused high schools – particularly for those groups who are under-represented in these high-growth fields (including minorities, females, and students from low-income families). Inclusive STEM high schools are designed to increase participation…

A New Approach to Fighting Flu
When most people hear the term “infectious disease,” it’s likely they think of illnesses that have been prominent in the news lately, such as Zika virus, MERS and Ebola. But there is a disease that poses a much broader and more imminent threat to most of us: influenza. Seasonal influenza viruses infect five to 20…
