GIS Implementation Issues and Strategies in K-12 Education
Following a teacher's initial decision to integrate GIS into the curriculum as a spatial learning tool, three important issues immediately arise. Educators must first address several factors that significantly affect the successful implementation of GIS technology. A second consideration is the development of appropriate learning contexts for applying GIS in the classroom. Lastly, effective instructional approaches must be adopted. We have reviewed the findings of an educational research project supported by the National Science Foundation that explored each of the above issues. A second project that examined the applications of GIS in teacher preparation programs will be discussed.

GIS in the K-12 Classroom: Staff Development and Instructional Materials for Inquiry-Based Learning
ArcView GIS is a powerful tool that can offer students many opportunities for engaging in critical thinking and inquiry. GIS, by its very nature, has the ability to support educational reform of the kind advocated by leading systemic change researchers (Means, 1994). Because ArcView GIS is a tool, as opposed to a multimedia package, there is a need for instructional materials and professional development to help teachers incorporate this technology into their classrooms. Using its experiences developing instructional materials for a similar visualization tool, NIH Image, CIPE is developing guided discovery lessons and professional development to help students and teachers discover GIS.

Instructional Strategies for Environmental Education: The GIS Way
Meeting the challenge of teaching K-12 environmental science requires that students develop a "sense of place." Without a sense of place children and young adults cannot realistically see how their personal actions have relevance on a global scale. Using a GIS approach is an effective means of developing a sense of place. Discussion will cover use of GIS/ArcView GIS in the K-12 setting, challenges, obstacles, and solutions. The development of teacher training programs and examples of classroom projects emphasizing the themes of water and earthquakes and their implications for human activities will be highlighted.

Corvallis High School GIS: The Riparian Monitoring Project
The main focus of the stream monitoring program is a method of orchestration, on a meaningful level, of many disciplines of science. This orchestration includes monitoring a stream twice per year for a number of years, using many levels of High School students, and whenever possible other public agencies. To make the project scientifically meaningful one might choose an area with a sampling site above and below a site of human impact. A rancher's livestock grazing area along a stream is an example. The impacts can then be gauged and restoration or sampling a broader sense of environmental issues can be gained. ArcView GIS is used to compile and analyze data on chemical, biological and physical properties of the rivers.
The Harlem Environmental Access Project (HEAP)
HEAP is dedicated to using computers to raise the environmental awareness of schoolchildren in the five schools and a library in the Harlem section of New York City. HEAP seeks to empower them to take action and find solutions to local and global environmental issues. The primary goals of HEAP are four-fold:
- to engage students in learning about environmental issues that are relevant to their lives and their community;
- to encourage students to investigate their local environment and work for positive community change;
- to provide students with new technologies and new sources of information to assist them in addressing local environmental concerns; and
- to expose students to the possibilities of careers in environmental science, management, and law. The environment may be the single most important area of scientific and policy activity for the coming century, and among the students in Harlem's schools today are many of our future environmental scientists, engineers, managers, and political leaders.

Ecological Subregions of the United States—USFS
The electronic (interactive) version of a 1994 publication by the US Forest Service (USFS), these companion sites are based on the National Hierarchical Framework of Ecological Units, designed to provide "a standardized method for classifying, mapping, and describing ecological units" in the US.
The first site, "Ecoregions of the United States," contains three simple color maps of the United States (including Alaska,Hawaii and Puerto Rico) showing generalized ecological boundaries.
At the coarsest spatial scale, the Ecosystem Domains map delineates Dry, Humid Temperate, and Humid Tropical Domains.
At the intermediate scale, an Ecosystem Divisions map delineates more than a dozen ecosystem types, ranging from tundra to rain forest.
At the finest scale, over 50 Ecosystem Provinces are delineated. By clicking on a color type for any map (i.e., an ecosystem type), users may access further information on the abiotic and biotic characteristics within that ecosystem.
A companion site, Ecological Subregions of the United States, contains the biophysical descriptions for the color-coded maps.
This is a solid resource for anyone seeking broad ecosystem classifications for the United States.
