The New Hampshire Education and Environment Team Summer Institute is a multi-day residential professional development program for K-8 educators. The program focuses on natural science content and related teaching skills with the hope that educators will integrate more natural science instruction into their curriculum. The theme and session topics vary from year to year. During the academic year teachers have the option of attending additional professional development workshops organized by the New Hampshire Education and Environment Team. NHPLT plans on using the evaluation results to measure changes in teacher practice, leverage professional development resources, inform the national network of PLT programs, and enhance NHPLT evaluation capacity.
