The Domestication of Ginseng

Many students enter classes with a very Orientalist mental map of the region usually called the Middle East. This is understandable considering the information and images of the region that pervade our media landscape. In an effort to teach student how to critically examine media sources themselves, the author utilizes a blog format for student participation and discussion. The article describes how the geographic imaginations of the students involved became more nuanced through the process of finding, analyzing, and critiquing various media sources in a small online community.     

Activities to Develop a Spatial Perspective Among Students in Introductory Geography Courses

Abstract

Teaching students to gain a spatial perspective is one of the most difficult yet important components of geographic education. This paper presents a series of activities designed to develop a more comprehensive understanding of spatial concepts among students in introductory geography courses. The activities and content are most appropriate for high school or university undergraduate students. An evaluation of these activities demonstrates that they enhance the student's spatial perspective and their understanding of the role of spatial concepts in geography.     

Defining Appalachia: Public Policy and Regional Dynamics in Appalachia's Low-income Counties, 1965-2000

Abstract

The extant literature on place location learning resolves in varying degrees that place location knowledge (PLK) is deficient in the United States and abroad. This is particularly true for younger school-attending age groups. This study has three main aims: to investigate the validity of that claim in regard to secondary-level students in Dublin by testing their PLK; to assess what characteristics of tested place locations render some sites more visible in students' eyes than others; and to investigate statistically what traits of the respondents shape their PLK. The implications of these findings on geographic education and future research are also discussed.     

Mental Mapping: A Lesson That Creates Itself

Abstract

Mental image and place-preference maps of college students in Florida were created through a two-part lesson. The patterns revealed by these maps were linked to students' life experiences, census data on migration and income, and similar studies conducted in other states. Students prefer states with established migration links to Florida and better income/job opportunities. Because the maps could not be created without their input, students were wholly engaged in a lesson that uses concepts in population geography and cartography to fulfill several national geography standards.     

Books,Places, Regions—A Natural Blend

Abstract

Children love books, and through carefully chosen ones geographic concepts can be conveyed. Books are good resources—great background material for describing a place, emphasizing the culture of a region, highlighting a geographical issue, or clarifying where a place is in the world. This article explains how literature encourages geographic thinking, builds geographic skills, and develops lasting mental maps of places and regions.

Demographic Transition: Threat to Developing Nations

Abstract

As computers become commonplace in the nation's schools, interactive maps are finding their way into the geography classroom. Students can use electronic atlases to access information as well as use authoring software to produce their own interactive maps. Does this change in media correspond to better geography education for our children? This article addresses whether using interactive maps for gathering and presenting information can have a positive influence on learning geography content. A two-week experiment was conducted in five 7th grade classrooms. Students in four of the classes researched and produced map products using both traditional and computer-assisted techniques. The fifth class was a control group. A pretest and two post-tests were given to quantitatively assess student learning after each project. Also, students were given a qualitative questionnaire to determine their attitude towards the different techniques. Quantitative results of the study indicate that there was no significant difference in student post-test performance after using each of the techniques, but qualitative results suggest that students prefer using the computer techniques over the traditional methods for gathering and presenting information.

Anthropogenic relief changes in a long-lasting lignite mining area (‘Ville’, Germany) derived from historic maps and digital elevation models

Humans constitute one of the main geomorphological agents in modern times. As an example, post-mining regions represent a typical landscape of the Anthropocene. Strong relief modifications are particularly obvious with open pit mining. However, many existing mining areas are lacking detailed pre-mining information for the quantification of anthropogenic relief changes, which is a considerable challenge in regions with historic mining activities. Here, the Ville (Rhenish lignite district, Germany) is used to quantify surface mining induced relief changes in one of the oldest and currently largest lignite districts in Europe. Historical maps from first geodetic mapping in 1893 enabled construction of a historic digital elevation model to quantify the relief changes in comparison to elevation data from 2000 and 2015. The vertical accuracy of the historic data is remarkably high, with relief differences < 2 m in areas not affected by mining. In total, 49.2% of the investigated area (184 km²) shows a relief deficit and 14.5% has positive relief differences. Absolute changes account for more than 80 m heightening (dumpsites of overburden) and lowering of the natural relief (pits). Besides these altitudinal changes, overall steeper slopes are significant for the new topography, but levelling exists likewise. The spatial variabilities are discussed in the context of the regional geology and the mining techniques. Undoubtedly, such large-scale anthropogenic relief changes persist for a very long time and will last as a human legacy far into the future. Only the detailed reconstruction of the pre-mining relief offers the ability to clarify the dimension of humans as geomorphological agents and to understand landscape perception. Due to the fact that the impact of open pit mining has such a large vertical and horizontal extension, their consideration as part of anthropogeomorphology can significantly contribute to support future Critical Zone research in the Anthropocene.
