Implementing a High School Level Geospatial Technologies and Spatial Thinking Course

Understanding geospatial technologies (GSTs) and spatial thinking is increasingly vital to contemporary life including common activities and hobbies; learning in science, mathematics, and social science; and employment within fields as diverse as engineering, health, business, and planning. As such, there is a need for a stand-alone K–12 curriculum in this area rather than the more piecemeal integration of GSTs and spatial thinking that is more common in today's schools. This article discusses the development of a systematic GST/spatial thinking course and analyzes how this course promoted student learning in these areas as well as developing problem-solving skills in other fields and applications.     

Professional Technologies in Schools: The Role of Pedagogical Knowledge in Teaching With Geospatial Technologies

Preparing learners for the future requires twenty-first-century teaching that integrates professional tools in the classroom. Geospatial technologies (GST), which represent geographical professional technologies, lack robust integration in high school geography. Researchers continue to ask why educators teach about rather than with GST. Understanding teacher decisions is paramount. This mixed methods study examined commonalities among teachers who use GST using Mishra and Koehler’s (2006 Mishra, P., and M. J. Koehler. 2006. Technological pedagogical content knowledge: A framework for teacher knowledge. Teachers College Record 108 (6):1017–54.[Crossref], [Web of Science ®] , [Google Scholar]) Technological, Pedagogical, Content Knowledge (TPCK) framework as a theoretical lens. This investigation examined whether geography teachers who exhibit stronger geospatial TPCK used GST more frequently than other teachers who exhibited a less developed knowledge base.     

Integrating Geospatial Technologies in Fifth-Grade Curriculum: Impact on Spatial Ability and Map-Analysis Skills

This study explores the effects of geographic information systems (GIS) curriculum on fifth-grade students' spatial ability and map-analysis skills. A total of 174 students from an urban public school district and their teachers participated in a quasi-experimental design study. Four teachers implemented a GIS curriculum in experimental classes over six weeks while three teachers continued with regular teaching in control classes. Both groups completed pre- and post-tests measuring spatial ability and map-analysis skills. Students in the GIS classes demonstrated more growth over time in spatial ability and map-analysis skills than did their peers in the control classes.     

Geospatial Thinking and Spatial Ability: An Empirical Examination of Knowledge and Reasoning in Geographical Science

This study examined the relationships between geospatial thinking and spatial ability, focusing on knowledge and reasoning about fundamental concepts in geospatial science. Scores on a geospatial thinking test had low correlations with each other, compared to high correlations among scores on spatial ability tests, and the degrees of relationship between geospatial thinking and spatial ability depended on the type of geospatial thinking. Expert geospatial scientists did not outperform students on spatial ability tests, suggesting that expertise in geospatial science might not simply be explained by superiority in spatial ability. The results point to the necessity of targeted instruction for geospatial learning.     

Affecting Geospatial Technologies: Toward a Feminist Politics of Emotion*

Building on earlier contributions to feminist understanding of geospatial technologies (GT), I seek to further develop feminist perspectives on GT along new directions. I argue that an attention to the importance of affect (feelings and emotions) and the performative nature of GT practices offers a distinctive critical edge to feminist work on GT. I emphasize the need for GT practitioners to contest the dominant meanings and uses of GT, and to participate in struggles against the oppressive or violent effects of these technologies. I argue that only when emotions, feelings, values, and ethics become an integral part of our geospatial practices can we hope that the use of GT will lead to a less violent and more just world.     

Preparing Preservice Teachers to Incorporate Geospatial Technologies in Geography Teaching

This study evaluated the efficacy of geospatial technology (GT) learning experiences in two geography curriculum courses to determine their effectiveness for developing preservice teacher confidence and preparing preservice teachers to incorporate GT in their teaching practices. Surveys were used to collect data from preservice teachers at three intervals over one semester. Results indicate preservice teachers' confidence and competencies to successfully integrate GT in their teaching increased over the duration of the study. The findings highlight the value of providing GT learning experiences in geography curriculum courses and contribute to the literature on preparing preservice teachers to incorporate GT in teaching geography.     

Teaching GIS in Geography*

Although numerous courses in geographic information systems (GIS) have been introduced into the geography curriculum over the past few years, there has been remarkably little debate over the issues involved. This paper first discusses the arguments for geography as an appropriate disciplinary setting for GIS teaching at the undergraduate level. This is followed by a discussion of the nature of GIS courses and their appropriate place in the undergraduate geography curriculum. The final section of the paper describes the NCGIA Core Curriculum project and examines its significance in this broader context.

Integration of Geospatial Science in Teacher Education

Abstract

One of the primary missions of our university is to train future primary and secondary teachers. Geospatial sciences, including GIS, have long been excluded from teacher education curriculum. This article explains the curriculum revisions undertaken to increase the geospatial technology education of future teachers. A general education class introducing geospatial technology to the general student body has been developed, a cartography class has been modified to provide applied geospatial experience explicitly for future teachers, and a service learning partnership with local K–12 schools has been established where students are working with teachers to integrate geospatial sciences in their academic programs.     

Geographic Information Technologies and the History of a Shoreline: The Case of Chapter 91 in New Bedford,Massachusetts

Abstract

This article discusses the use of geographic information technologies to assist researchers in the exploration of historical databases. The case study is a pilot project in which we used geographic information systems (GIS) and global positioning systems (GPS) to study the history of the Public Waterfront Act (the “Chapter 91” program), a policy designed to balance private property rights, public interest, and environmental protection in the Massachusetts tidelands. The issues discussed range from the role of GIS in society and its limitations as a representational tool to the ability of current GIS to deal with historical data and to manage temporal attributes.

A Pedagogic Framework to Link GIS to the Intellectual Core of Geography

Abstract

This paper aims to develop a new pedagogic framework for teaching GIS at the college and university level using Berry's geographic matrix. By synthesizing different schools of thought, this paper argues that GIS education essentially involves two aspects—how to teach about GIS and how to teach with GIS. Berry's geographic matrix can be used to tie these dual aspects of GIS education together neatly. As an abstract representation of geographical phenomena, the geographic matrix embeds all three entities of GIS—location, attribute, time—and thus can help GIS instructors teach about GIS. As a synthesis of geographical approaches, the geographic matrix can assist GIS instructors teach with GIS. This paper demonstrates that GIS is actually an implementation of Berry's geographic matrix. Furthermore, the 10 approaches to geographical analysis, originally proposed by Berry for the geographic matrix, can be executed routinely in a GIS environment. By incorporating Berry's geographic matrix into GIS education, teachers can enable students to surpass technical issues and to appreciate the conceptual and functional linkages between GIS and geography's intellectual core.     

Student Learning of Place: Learning Progressions Can Help Fill the Gaps

This commentary is a response to Larsen and Harrington's article titled “Developing a Learning Progression for Place” (2018). The commentary includes a discussion of the benefits to other content areas that research on student learning of place can provide. The commentary also describes the coherence that learning progressions can bring to research on student learning of complex, interdisciplinary domains of study.     

Paper versus Pixel: Effectiveness of Paper versus Electronic Maps To Teach Map Reading Skills in an Introductory Physical Geography Course

Abstract

This article addresses the lack of outcome-based research on the integration of technology into pedagogy at the undergraduate college level. It describes a study performed at a Midwestern university, testing the relative effectiveness of paper and electronic topographic maps for teaching map-reading skills, and considers the relationship between learning styles and paper or digital map preference. Results indicate that, although student map skill performance did not differ significantly with the use of paper or electronic maps, students preferred paper maps. Neither their performance nor their preferences were related to learning style. The article discusses the significance of these findings.     

Observational Work for Children

Abstract

Geographic information systems (GIS) are computer-based tools for geographic data analysis and spatial visualization. They have become one of the information and communications technologies for education at all levels. This article reviews the current status of GIS in schools, analyzes the requirements of a GIS-based learning environment from constructivist perspectives, and discusses the major issues in the design of a constructivist GIS-based learning environment based on experience from the development of World Explorer, a GIS-based learning environment that provides a theme-oriented data and information base, supports multiple representations and multiple linkages of information, and facilitates interactive learning and knowledge construction.     

Sources of Literature for Commercial Geography

Abstract

The No Child Left Behind (NCLB) legislation has resulted in declining classroom time dedicated to geography instruction, especially in grades K-8. To combat this problem, a National Geographic Society Grosvenor grant provided resources allowing 28 teacher-authors to generate a package of more than 80 lessons that combine the teaching of geography and mathematics skills tested on Arizona's state mandated testing. When taught in 113 piloting classrooms that mirror Arizona's student demographics, GeoMath lessons generated statistically significant increases in performance in math skills and improved understanding of geography standards. In addition, a fourth of the K-8 piloting teachers surveyed felt that teaching GeoMath lessons increased in their level of comfort in teaching mathematics. Given the success of this GeoMath strategy, and a prior GeoLiteracy program, we advocate here a national agenda of articulating geography curriculum to high-stakes tested subjects of reading and math.     

Reading the World: Integrating Geography in an English Language Learner Literacy Program

Abstract

English language development classes focus on teaching students of other languages how to speak, read, and write English. They must also prepare students to meet the many standards and requirements that are prerequisites to content classes, such as geography, and high school graduation. This discussion focuses on the integration of literacy and geography in a classroom with English language learners. A common English language development model, the “Into, Through, Beyond” model of learning, sets a foundation that integrates components of English language acquisition with language arts and geography standards. In turn, this approach to learning prepares the learners for success in social and academic arenas.
