EREN has developed student learning goals focused on cross-cutting collaborative science themes that apply across diverse EREN projects. EREN also has an assessment instrument to measure student progress toward these goals and tested this instrument with students in 21 different undergraduate courses in 2014 and 2015. The results of this effort have been published here: https://eric.ed.gov/?id=EJ1275654. A copy of the EREN learning goals and the assessment instrument is available here. We welcome suggestions for improvement and collaborations on measuring student learning in team science contexts. Please contact erenteam@gmail.com to start the conversation!
