Based on the use of graphing calculators by students enrolled in calculus, there is enough material here to cover precalculus review, as well as first-year single variable calculus topics. Intended for use in workshop-centered calculus courses, and developed as part of the well-known NSF-sponsored project, the text is for use with students in a math laboratory, instead of a traditional lecture course. There are student-oriented activities, experiments and graphing calculator exercises throughout the text. The authors themselves are well-known teachers and constantly striving to improve undergraduate mathematics teaching.

During 2008, the ERMN began collecting data using the Wadeable Streams Monitoring Protocol, which addressed the benthic macroinvertebrate and water quality vital signs. This report summarizes the status of benthic macroinvertebrate communities and water quality in selected wadeable streams throughout parks in the Northern Appalachians Ecoregion of the ERMN (i.e., Allegheny Portage Railroad National Historic Site, Delaware Water Gap National Recreation Area, Johnstown Flood National Memorial, and Upper Delaware Scenic and Recreational River). Data collected since 2008 (with emphasis on data collected during 2010) are presented and discussed. All data were collected following methods detailed in the Wadeable Streams Monitoring Protocol (Tzilkowski et al. 2009).
