This report is based on several evaluations of NSF-funded geoscience projects at Stony Brook University on Long Island, NY. The report reviews the status of K-12 geoscience education, identifying challenges posed by the Next Generation Science Standards (NGSS), the experiences of university faculty engaged in teacher preparation, state requirements, and the current high school science curriculum. The study then describes and analyzes enrichment, active learning strategies employed in summer programs at Stony Brook. The study also describes professional development for schoolteachers, also at Stony Brook. Next, we review the attitudes of undergraduates toward the geosciences. Finally, the report identifies best practices in the geosciences, based on an analysis of the data previously discussed. The following are appended: (1) High School Teachers Workshop Survey; (2) Survey of High School STEP Students; and (3) Survey of Stony Brook CSTEP Students.
