Case studies of individualized professional development at an outdoor education center.

摘要

Since the publishing of A Nation at Risk in 1983, educators across the country have directed attention and formal research studies towards discovering why American schools are not producing graduates who measure up to students in other countries. Research has been done which deals with children's responses to learning science while utilizing a variety of educational strategies. Factors such as gender, ethnicity, class size, length of the school day or school year, equipment availability and usage, have been studied and their impact analyzed. New assessment devices and testing instruments have been used to measure the amount and quality of their learning. Significant in its absence from most studies is the recognition of what classroom teachers believe about science, what they feel to be the best way(s) to teach science, and how they actually teach science. Related research on these factors laid the ground work for this study.;Teaching is a profession characterized by a need for life-long learning. Some teachers study for advanced degrees. "Workshops" and "teacher institutes", either on-site at their own schools or through other enrichment situations provide learning opportunities for others. Informal educational institutions which have provided science enrichment field trip opportunities have recently begun to look at the curriculum goals and expectations of the state boards of education and regional school districts. As they become informed about these goals, their enrichment opportunities are found to serve the schools more fully.;This study focuses on the Arlington Echo Outdoor Education Center, where the staff does not merely plan, prepare for, and present lessons on various age-appropriate science topics to schoolchildren which come to them. Instead, it is the policy of this center to prepare the individual classroom teachers so that the teacher assumes the responsibility to provide the preparation of the children for the experience, the facilitation of the various activities and lessons while at the center, and the assessment of the student's learning following the experience. The staff works with each teacher to prepare them to use transdisciplinary science lessons which were planned to satisfy and enrich state, district, and school expectations (Outdoor Education Guidebook, 1997). The staff members believe that if the teachers are prepared to do these things, not only will the current students learn more, but that the teacher will experience growth professionally and this will impact more children over time. The teachers gain science content knowledge and learn constructivist teaching strategies while learning how to use the facilities and equipment safely and confidently. Ideas for preparatory and follow-up activities are made available. This study looked closely at the individualization of the professional development provided by this informal science institution.;Data from observations of professional development sessions as well as the on-site experiences with the children were used in the study. Teachers were asked to reflect on the degree to which the Arlington Echo approach to professional development was beneficial in building their confidence about providing science-based, interdisciplinary experiences for their students, with comparisons made between the responses of veteran teachers and those of teachers with fewer years of experience. Through the reflections of the participant teachers, it was possible to gather data about whether their beliefs about science and about how science is best taught were modified by this experience.
