At Lawrence University rapid, wholesale personnel changes allowed us the unique opportunity to completely rethink our curriculum in 2000. The major challenge that we faced was how to offer a curriculum that reflects the growing interdisciplinarity and complexity of the geosciences with a relatively small faculty (three members). We addressed this issue by identifying the essential elements of a geoscience program and reconciled these with our own priorities, strengths, potentials, and limitations. We then built the strongest possible program given these resources and constraints. As new faculty members were hired, we deliberately sought out versatile, flexible candidates whose training embraced several sub-disciplines. As we discussed the skills and concepts we considered essential for geology students and assessed the expertise of our faculty, we concluded that for us the most efficient curricular framework would emphasize 1) fundamental processes that drive Earth systems and 2) connections with cognate sciences. This shift in focus also has allowed us to serve the interdisciplinary Environmental studies curriculum in an integral way, without undercutting the department's own mission. There are serious challenges to departments looking to change their core curriculum. Resistance to change can come from both within departments and through external entities. Because all of our faculty were new to Lawrence, we faced no internal resistance. However, we have faced some challenges in explaining our major to "old school" alumni, emeriti, and to some graduate programs who note the lack of specific course titles on student transcripts. We also have found the need to make adjustments to our initial curricular redesign to effectively cover topics such as optical mineralogy and sedimentology and stratigraphy. Finding appropriate textbooks for our courses continues to pose a problem. Despite these challenges, we are very positive about the student response to our changes. Enrollments in our courses are up almost 20% and we see an increasing number of students from other sciences in our upper level classes. Although the number of majors has not changed significantly, we have noticed that more of our majors are attending graduate school or finding employment in the geosciences. As the scope of the geosciences grows and the boundaries between disciplines blurs, there is no longer any possibility of `comprehensive coverage' in the undergraduate curriculum. We do not consider our curriculum a universally applicable template. But we do believe that leading geoscience programs of the future will emerge from departments that identify their priorities, know their strengths, and construct their curricula based upon these intellectual foundations.

The Natural Science Program at the University of New Mexico: Geosciences Play a Central Role in Preservice Teacher Training

Nyman, M W (mwnyman@unm.edu) Ellwein, A L (ellwein@unm.edu) * Geissman, J W (jgeiss@unm.edu), Dept. Earth and Planetary Sciences, Northrop Hall, MSC03 2040, 1 University of New Mexico, Albuquerque, NM 87131, United States McFadden, L D (lmcfadnm@unm.edu) Crossey, L J (lcrossey@unm.edu)

An important component for future directions of geoscience departments is public education. The role of geoscience departments in the preparation and professional development of K-12 teachers is particularly critical, and merges with other teaching missions within the University. The importance of geoscience content for teachers (and the general public) is evident in the numerous earth science related public policy issues that are the subject of ever-increasing attention (climate change, energy resources, water utilization, etc.). The earth and space sciences are not only included in both state and federal science content education standards but are also inherently interesting to students and therefore provide an important gateway to foster interest in science as well as other scientific disciplines. For over 10 years, the Department of Earth and Planetary Sciences (EPS) at the University of New Mexico (UNM) has housed and supported the Natural Science Program (NSP), which provides science content courses and numerous programs for K-12 pre- and in-service teachers. Classes and laboratories are integrated, and are capped at 21 students in the 200-level courses, assuring an active and supportive learning environment for students who are typically science-phobic with negative or no experiences with science. Enrollments are maintained at ~150 preservice teachers per semester. The program is staffed by two lecturers, who have advanced degrees in the geosciences as well as K-12 teaching experience, and several part time instructors, including graduate students who gain valuable teaching experience through teaching in the NSP. With continued support from the department, the NSP has expanded to develop robust and functional relationships related to science teacher professional development with Sandia National Laboratories and local school districts, initiated development of a graduate certificate in science teaching and, advanced a proposal for the development of an Energy Education Program at UNM. Finally, the NSP provides a ready avenue for the incorporation of grant funded faculty research into teacher education programs, thus providing a viable and functional method for addressing broader impacts related to NSF funded programs.

Two ongoing initiatives funded by the NSF-GEO and NSF-HRD directorates are being used to enhance the geospatial program at the North Carolina Central University (NCCU) to make it a leader, regionally and nationally, in geoscience education. As one of only two Historically Black Colleges and Universities (HBCUs) in the southeast offering Geography as a major, NCCU has established a Geospatial Research, Innovative Teaching, and Service (GRITS) Center and has partnered with American Society for Photogrammetry and Remote Sensing (ASPRS) to offer "Provisional" GIS certification to students graduating with Geography degrees. This presentation will focus on the role that ongoing geospatial initiatives are playing in attracting students to this program, increasing opportunities for academic and industry internships and employment in the field after graduation, and increasing awareness of the NCCU geosciences program among GIS professionals in North Carolina. Some of the program highlights include "Provisional" ASPRS certification recently awarded to three NCCU graduate students – the first three students in the nation to complete the provisional certification process. This summer GRITS Center faculty conducted two GIS workshops for academic users and three more are planned in the near future for North Carolina GIS professionals. In addition, a record number of students were awarded paid internship positions with government agencies, non profit organizations and the industry. This past summer our students worked at NOAA, NC Conservation Fund, UNC Population Center, and Triangle Aerial Surveys. NCCUs high minority enrollment (at the present above 90%) and quality and tradition of geoscience program make it an ideal incubator for accreditation and certification activities and a possible role model for other HBCUs.

The Science Division of City College (CCNY) has implemented a joint undergraduate program with the Grove School of Engineering at CCNY that allows for both a Bachelors of Science and a Bachelors of Engineering using a synergistic Earth System Science (ESS) curriculum . The Science Core uses creative new courses that include ESS: Systems Analysis of the Earth, ESS: Modeling/Databases, Geographic Information Science, and Remote Sensing to expand the spatial science consideration. The Engineering Core supplies background fundamentals in instrumentation design and operation through courses such as Computer- aided Analysis Tools, Basics of Electrical Circuits and Introduction to Satellite Remote Sensing. This represents a dramatic broadening of a classical earth science degree and a shift to a global resource paradigm. The original geology course is now reconstructed to reflect the new points of emphasis. The Freshman level course, ESS: Introduction to Earth System Science and Engineering contains a dramatically modified set of laboratory exercises and exercises with an entirely new focus that incorporate experimental design, and an application of engineering skills. The new laboratory exercise utilize optical benches with light sources and photovoltaic solar cells to study optical phenomena. From a scientific standpoint, students locate the theoretical sun position, and estimate atmospheric light scattering properties, and then use the solar cell information to construct design plans for renewable energy installations. Laboratory simulations are linked to issues such as global warming and satellite data recovery systems. Laboratory exercises also simulate data streams recovered at CCNY using LIDAR and other information published at CCNY on AERONET. The effectiveness of the exercises, including qualitative student responses, is measured to estimate the impact of exercises on student comprehension. We are specifically interested in the manner in which students apply these newly acquired skills to real-world environmental engineering situations.

Linkages To Engagement At University of Wisconsin-Parkside

* Evans, C V (evansc@uwp.edu), University of Wisconsin-Parkside, 900 Wood Road, Kenosha, WI 53141-2000, United States

The University of Wisconsin-Parkside Department of Geosciences is a small but successful department within one of the smallest comprehensive universities in the University of Wisconsin system. Formerly a more traditional "rocks and petroleum" program, the Department was on the verge of extinction in 1999. Fortunately, a farsighted Dean intervened and proposed a change of direction for the department, filling in behind retirements with new leadership and a strong environmental focus. Several strategies have been key to resuscitating the Department to its current status, increasing majors, faculty, and SCH/FTE. First, we embraced our niche as the environmental resource, specifically offering urban or other developed settings for our focus on environmental quality. Secondly we revamped our majors' curriculum to enable our students to learn to integrate practical technological skills in sampling, analysis, instrumentation use, and civic engagement to produce positive outcomes at both physical and social levels. Thirdly, our Department has become a strong and active supporter of a teacher preparation program that is undergoing important curriculum and organizational changes. Our newest faculty addition is an atmospheric chemist with significant teaching responsibility in our campus' new Liberal Arts major for elementary school teachers. Geosciences faculty also vigorously support a certificate program in Community Based Learning, direct the campus minor in Environmental Studies, and have actively participated in campus initiatives such as First Year Experience, General Education reform, the campus' Teaching and Learning Center, and collaborative course offerings that link academic skills (math, reading, writing) courses to extra support in General Education science courses. In addition, the Department has taken campus leadership in participation in the national SENCER initiative, which links science education and civic engagement. Finally, we have also amended and upgraded our merit review criteria so that they explicitly support faculty participation in active learning approaches in the classroom, and faculty research that is applied to issues of active regional concern, and which involves our students in the research process.

As the scientific world becomes more interconnected, careers in geosciences regularly require cooperation, communication, and comprehension across disciplines. In response, faculty at the University of Vermont (UVM) have developed and are modifying an interdisciplinary watershed field course to provide both a valuable learning experience in watershed science for students and a tested prototype for collaboration and cooperation between faculty, departments, and administrators. The field course introduces concepts of watershed science, an inherently interdisciplinary field of study for which there is often no specific academic department (www.uvm.edu/watercamp). The field exercises begin in Lake Champlain, New England's&plargest inland water body. To maximize relevance, the focus is on threats and current problems associated with large water bodies. The students then move to the mountainous headwaters of a major drainage into Lake Champlain and follow it back down into Lake Champlain. The 3.5-week, 4-credit course consists of exercises created by faculty from different academic departments representing three different schools within the university including: civil and environmental engineering, geography, geology, and natural resources. A pair of faculty members from different departments lead each day's activities ensuring that students are exposed to a range of faculty interaction, connections, and cooperation between specialties. The general design of the course is modular; content and faculty can be changed as desired from year to year to take advantage of current field research projects, visiting or absent faculty, or unusual and unique field opportunities. Surveys collected from students taking the first offering show learning over a broad range of disciplines and positive attitudes about the teaching and learning styles associated with field courses. Knowledge surveys completed by the students before and after the class showed an overall increase in self assessed knowledge of the course concepts, with a positive mean survey increase of one on a three point scale (n=8). Before and after class attitude surveys showed significant increases in the students perceived benefit of writing lab reports, working in groups and using computer based materials (Wilcoxon Signed Rank Test n=7: p>t = 0.063; Wilcoxon Signed Rank Test n=7: p>t=0.063; and Paired t-test n=7: p>t = 0.0391, respectively). There was also a significant decrease in the perceived usefulness of lectures (Wilcoxon Signed Rank Test n=8: p<t = 0.015). These survey results demonstrate that this field course develops skills needed to participate effectively in interdisciplinary research and learning.

Connecting graduate students with experts in a given discipline is vital to their success but has often been challenging because of logistics, costs, and scheduling. Advances in Internet video-conferencing now allow multiple parties to meet simultaneously in a virtual classroom environment. Here we describe the mechanics of a recent student-directed graduate-level course that enabled students to directly engage in scientific discussion with experts. Conducted under the auspices of the Earth Hazards (EHaz) Consortium, the spring 2007 Volcano Instability course connected nine previously disparate groups over North America in a combined learning and cultural experience. Each week course participants (including the guest speaker, students and university professors) reviewed current journal articles and a speaker presentation, and used Marratech Internet video- conferencing software to meet online and discuss the material with an expert on the subject. Internet video-conferencing provides an inexpensive and innovative approach to teaching across international boundaries. The EHaz 2007 Volcano Instability course connected 14 experts with 64 students and professors. Many universities can participate through this approach, allowing an advanced graduate class that normally contains 4 - 8 students on one campus to become a class of 50 or more dispersed over many campuses. As evidenced by overwhelmingly positive course evaluations, the approach was stimulating and conducive to learning, and has great potential for application over many other disciplines. This dynamic interaction between students and experts will ultimately raise the standard of instruction and motivate students to self-guide their learning experience to levels of greater understanding. http://www.geo.mtu.edu/EHaz/VolcanoInstability.htm

To a greater extent than most science programs, geology is underrepresented in K-12 curricula and the media. Thus potential majors have scant knowledge of academic requirements and career trajectories, and their idea of what geologists do—if they have one at all—is outdated. We have addressed these concerns by developing a dynamic, web-based academic roadmap for current and prospective students, their families, and others who are contemplating careers in the geosciences. The goals of this visually attractive "educational pathway" are to not only improve student recruitment and retention, but to empower student learning by creating better communication and advising tools that can render our undergraduate program transparent for learners and their families. Although we have developed academic roadmaps for four environmental and life science programs at the University of Rhode Island, we focus here on the roadmap for the geosciences, which illustrates educational pathways along the academic and early-career continuum for current and potential (i.e., high school) students who are considering the earth sciences. In essence, the Geosciences Academic Roadmap is a "one-stop'" portal to the discipline. It includes user- friendly information about our curriculum, outcomes (which at URI are tightly linked to performance in courses and the major), extracurricular activities (e.g., field camp, internships), careers, graduate programs, and training. In the presentation of this material extensive use is made of streaming video, interviews with students and earth scientists, and links to other relevant sites. Moreover, through the use of "Hot Topics", particular attention is made to insure that examples of geoscience activities are not only of relevance to today's students, but show geologists using the modern methods of the discipline in exciting ways. Although this is a "work-in-progress", evaluation of the sites, by high school through graduate students, has been strongly positive. Our presentation will include a demonstration of the Academic Roadmap, and a template that can be used by other geoscience departments to easily design websites.

CAN EARTH MATERIALS BE ADEQUATELY COVERED IN A ONE- OR TWO-SEMESTER COURSE?

* Hefferan, K P (kheffera@uwsp.edu), Department of Geography/Geology, University of Wisconsin-Stevens Point, Stevens Point, WI 54481, United States O'Brien, J (jamobrien@comcast.net), Geoscience Department, New Jersey City University, Jersey City, NJ 07305, United States

Traditional geology programs offer courses in mineralogy, optical mineralogy, igneous petrology, metamorphic petrology, sedimentology and economic geology. At many universities this suite of mineralogy/petrology courses has been supplanted by a one-semester or two-semester Earth Materials course. This interactive poster poses five questions to faculty and students related to the means by which Earth Materials can be delivered: 1) Available online syllabi demonstrate a wide variation in the topics addressed in Earth Materials courses; is there a standard core of key topics that must be covered and in what level of detail? 2) Can a one-semester or two- semester Earth Materials course adequately cover these topics? 3) Excellent textbooks exist in both mineralogy and in petrology; what textbooks, if any, adequately encompass Earth Materials? 4) How has the online environment changed the way in which we use textbooks in the classroom? 5) Given the evolution of geology programs, higher education and the global economy in the past twenty years, what additional changes can be anticipated with respect to delivery and demand of Earth Materials topics? Answers-- or at least related discussions-- to these questions are encouraged via verbal dialogue among participants and/or by comments written on the poster. Our goal is to solicit faculty, student and industry feedback to create a textbook, curricula and online materials that support an Earth Materials course.

Development of a geoscience curriculum in a small liberal arts college

* Toteva, T (ttoteva@randolphcollege.edu), Randolph College, 2500 Rivermont Avenue, Lynchburg, VA 24503, United States

Geoscience programs with emphasis on geophysics are traditionally offered in research type of universities. Most small liberal arts colleges do not have the resources to offer geophysics education. Randolph College (Lynchburg, VA) is becoming one of the few small schools that provide a unique opportunity for undergraduate students to acquire basic knowledge and skills in geoscience methods, in particular in geophysics. One faculty member was hired a year ago and charged to offer a number of classes and labs in geoscience. As a result of that today the college has a geophysics lab with a 250 MHz GPR antenna, a 12 channel Geometrics Geode, three sets of geophones, and sieve equipment for geotechnical work. The above equipment was acquired with funds from the college and outside sponsors. In addition, collaboration with Virginia Tech led to the installation of a new seismological station, with a broad band seismograph, on college land. This alone triggered incredible interest in earthquake seismology, not only from students but from the campus community as well. All the equipment is used both for classes and undergraduate research. It has a significant contribution to the rapid increase in interest in the Environmental Studies and Physics programs in the school. It allows the offering of new field based classes. Such classes are always of great interest to students because they provide hands-on experience. As a result of offering these new classes, two new B.S. programs were added to the curriculum – B.S. in Environmental Science and B.S. in Physics.

The growing need to understand environmental and geological processes, their impacts, and solutions in a dynamic world requires a diverse, multidiscipline, and multicultural approach in science and engineering. In the last few years, faculty at the University of Puerto Rico, Mayagüez have engaged in education and training activities aimed at developing a critical mass of students that can address a wide range of geoenvironmental problems through multidisciplinary research. Students of diverse age, gender, culture, and academic disciplines addressing different research questions work together in a common space. Hierarchy assignments use senior students as primary mentors, but foster work at parallel levels that require sharing and developing knowledge and research resources. The activities have resulted in a significant increase in the number of diverse students in science and engineering areas related to the environment.

Increasing Diversity in the Geosciences at the City University of New York

* Damas, C (CDamas@gc.cuny.edu), Graduate Center, CUNY, 365 Fifth Avenue, New York, NY 10016-4309, United States Johnson, L (leon.johnson@verizon.net), Medgar Evers College, CUNY, 1650 Bedford Ave, Brooklyn, NY 11225, United States McHugh, C (cecilia@ldeo.columbia.edu), Queens College, CUNY, 65-30 Kissena Blvd, Flushing, NY 11367, United States Marchese, P J (pmarchese@qcc.cuny.edu), Queensborough Community College, CUNY, 222-05 56 Avenue, Bayside, NY 11364, United States

The City University of New York (CUNY) is the nation's largest urban university, with 23 institutions serving a large number of underrepresented minority (URM) and women students at all levels of the pipeline - community college to graduate school. CUNY has a strong record of recruiting, enrolling, retaining and graduating URMs in science, technology, engineering and mathematics (STEM) fields. Current efforts are underway to increase the number of URMs in the geosciences. These efforts include: 1) involving students in research at all levels of the pipeline; 2) incorporating innovative and proven pedagogical methods into the classroom; and 3) mentoring of students by research scientists from CUNY and other participating institutions. At all levels of the pipeline, students are actively engaged in Space and Earth Science research. At the community college level, students are introduced to the scientific research process through familiar software such as MS Excel to analyze simple time series. At the senior colleges, students progress to multi-variate data analysis, and they also have the opportunity to go into the field to collect data. As graduate students, they are involved as mentors and supervise undergraduate student research. Program initiatives such as the CUNY pipeline provide stipends and academic enrichment activities (i.e., GRE training, applying to graduate school, etc.) throughout the summer and academic year. During the summer, students also have the opportunity to work with and be mentored by research scientists at a CUNY campus, at a NASA center or a national laboratory. Mentors advise students about graduate school and careers, serve as role models, and perhaps more importantly, provide encouragement to students who lack confidence in their ability to do scientific research. Students also are expected to present their research findings at meetings and conferences, both locally and nationally. In addition to their research experiences, students also benefit from classroom instructions that emphasize active learning, and the integration of research related activities. Proven educational materials and pedagogical methods developed at Medgar Evers College and Queensborough Community College have proven quite effective at engaging and assisting students who have conceptual difficulties in their science and mathematics courses. Overall, students demonstrate an increase in their conceptual understanding of the subject matter, as well an increase in their confidence to solve scientific problems and to become scientists.
