The Office of Shared Accountability (OSA) conducted an evaluation of the implementation of the second year (2011-2012) of the Science, Technology, and Engineering Leadership Program (STELP) in Montgomery County (Maryland) Public Schools (MCPS). Funding for STELP, including the evaluation study, is provided by a grant from the Howard Hughes Medical Institute (HHMI) to MCPS. The goal of STELP is to improve instruction in science, technology, and engineering and help students achieve science, technology, engineering, and mathematics (STEM) literacy (MCPS, 2010). This evaluation report addresses the second year of STELP. The focus of this evaluation was on implementation of the program in terms of continued training of a group of teacher leaders to develop online professional development modules for other MCPS science, technology, and engineering (STE) educators to view. Year two included both new and returning teacher leaders and built upon the professional development modules created in year one. This report summarizes key findings and offers recommendations. Also included are appendices: (1) Training Sessions' Feedback Surveys; (2) Program Evaluation Unit Project Rubric; (3) STE Staff Interview; (4) STELP Training Plan Peer and STE Specialist Review; (5) Training Session Schedule, Attendance and Outcomes; and (6) Participants' STELP Reflection.
