Pedagogy vs. reality: An investigation of supports and barriers when implementing NGSS storylines, a study co-authored by two NCSE staff, Lin Andrews and Blake Touchet, found that lack of administrative support, time constraints, difficulty with student sense-making, and mismatched classrooms are the largest barriers to implementation of NGSS storylines, while curriculum-based professional learning including working through the lessons from a student perspective, peer collaboration, autonomy, and flexibility were the largest predictors of successful implementation.
