Little explicit attention has been given to the impact of item pools on the validities and cross-validities of different background data scoring approaches. This study tests the idea that pools of items theoretically related to the performance of interest will outperform pools of items with no hypothesized relationship with the criterion. Validities and cross-validities of rational scales and empirical keys created from theory- and non-theory-based item pools were compared for 3 criteria. When size of the item pools was held constant, theory-based empirical keys (correlational and vertical percent) and rational scales showed larger validities and cross-validities than non-theory-based empirical keys …

Service learning is an undergraduate education strategy found across four program areas funded by the W. K. Kellogg Foundation (WKKF). This cross-foundation, retrospective evaluation examines 35 projects of $100,000 or more funded between 1985-95. Study information was based on qualitative data and approaches, with the majority of project activities and results self-reported by grantees. Written surveys and review of annual progress reports submitted by grantees were augmented by follow-up telephone inquiries and e-mails. Four international projects are included in the evaluations. Most projects used approaches involving classroom learning, community service, and reflection on service within the context of coursework. The …
