The purpose of this study was to provide a more in-depth analysis of the psychometric characteristics of the Principal’s Computer Technology Survey (PCTS). The PCTS developmental process yielded a 40–item survey with groups of items comprising five subscales (i.e., curriculum integration, perceptions, acquired expertise, needs assessment, and professional development). Principals’ responses to items within the five subscales was measured on a five-point Likert scale ranging from 1 (strongly disagree) to 5 (strongly agree). An expert panel reviewed the instrument plus exploratory factor analyses and confirmatory factor analyses were conducted. This analysis resulted in a restructured instrument …

The project described in this article explores how a series of conceptual ecological models can be used to portray the improvement in ecological understanding over the span of a short course. The course involved high school teachers working collaboratively on ecological research projects. Teachers were asked to construct qualitative conceptual models (a diagram of important ecosystem components and the linkages between these components) and write explanatory essays at three points during their research experience. The progression in development of teachers’ models spanned initial intuitive explanation, with misconceptions, to the post-test elaboration of a more complex and accurate understanding of ecological …
