Thirty-five Nebraska educators from across the state came together for five Saturday seminars during the 1995-96 school year to collaborate as they conducted classroom investigations. They earned 3 hours of tuition-free graduate credit. Action research was the tool for their investigations, guided by R. Sagor's book "How To Conduct Collaborative Action Research" (1992). This document presents reports on 22 projects conducted by these teachers. Their action research projects involved elementary, secondary, and higher education, and studied many aspects of education, including assessment and the communication of assessment results, performance based assessment, peer mentoring, cooperative learning, science instruction, mathematics instruction, and gender equity. The book is divided into: (1) summaries of the studies, containing the research questions, data analysis, and results of research studies; (2) "Researchers' Journeys," comments from participant journals; and (3) "Close- Ups," sample contents from three researchers' portfolios that provide an in-depth look at their research.
