Robots, Gps/Gis, And Programming Technologies: The Power Of "Digital Manipulatives" In Youth Extension Experiences, Bradley S. Barker, Neal Grandgenett, Gwen Nugent, Viacheslav I. Adamchuk Feb 2010

Robots, Gps/Gis, And Programming Technologies: The Power Of "Digital Manipulatives" In Youth Extension Experiences, Bradley S. Barker, Neal Grandgenett, Gwen Nugent, Viacheslav I. Adamchuk

The Journal of Extension

The study reported here examined the effectiveness of educational robotics combined with GPS/GIS technologies used as "digital manipulatives" in the teaching of concepts in science, engineering, and technology. Based on the success of previous summer camps, the study also examined a scaling-up of the intervention from 38 participants to 147. The 147 youth (ages 10-15) participated in one of six summer camps held in Nebraska during 2008. Results indicate that participants scored higher on the content posttest than the pretest. The study further examined the differential results. The article makes recommendations for further studies, while acknowledging the potential power of …


The Sky's The Limit: Integrating Geospatial Tools With Pre-College Youth Education, John Mcgee, Jeff Kirwan Feb 2010

The Sky's The Limit: Integrating Geospatial Tools With Pre-College Youth Education, John Mcgee, Jeff Kirwan

The Journal of Extension

Geospatial tools, which include global positioning systems (GPS), geographic information systems (GIS), and remote sensing, are increasingly driving a variety of applications. Local governments and private industry are embracing these tools, and the public is beginning to demand geospatial services. The U.S. Department of Labor (DOL) reported that the pool of geospatial professionals is unable keep up with demand. It is important that pre-college educators begin implementing these tools in the classroom to stimulate the educational pipeline. Twenty-four teachers from Fairfax, Virginia were involved in an educational approach that integrates GIS with civic and environmental education.


Watershed Modeling Using Gis Technology: A Critical Review Jan 2010

Watershed Modeling Using Gis Technology: A Critical Review

Journal of Spatial Hydrology

Understanding and managing water resource problems involves complex processes and interactions within the watershed surface and subsurface. The imposition of total maximum daily load (TMDL) regulations on the pollutant influx to a watershed has created a strong demand for new assessment tools. The spatial scales relevant to transport of the pollutants may span many orders of magnitude, ranging from field plots to regional hydrological systems. As the demand for and development of watershed modeling capabilities have evolved, geographic information systems (GIS) in tandem with remote sensing technologies have played an essential role supporting both data collection and analysis.
