This report summarizes the activities and findings of Horizon Research, Inc. (HRI) in its external evaluation of Rural Physics Teacher Resource Agents (PTRA) project. The report details HRI's work and findings since June 2002. The project is on schedule for going to scale with the rural centers model, establishing four centers in Year One and receiving commitments for additional sites in Year Two. The project has also sold the rural center model to the PTRAs. The project has refined and clarified the role and responsibilities of the Rural Regional Coordinators, learning from their first attempts at implementing the rural model. In addition, RRCs relieve the PTRAs from the task of institute logistics, giving them more time to plan and prepare for workshop delivery. The project's decision to focus each rural institute on a coherent scope and sequence allows for more time to be spent working with outreach participants on issues of content and pedagogy. This focus is important for the target audience of under-prepared or cross-over physics/physical science teachers. Four appendices are included: (1) Outreach Participant Questionnaires; (2) Analysis and Reporting of Questionnaire Data; (3) Additional Baseline Data on Outreach Participants; and (4) Additional Data From the Activity Use Survey. (Contains 10 footnotes and 21 tables.)
