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.     

The Trade and Industries of Western South America

Abstract

This research was based on an instructional module developed and used to investigate whether GIS can be used to enhance fourth grade students' geographic knowledge and map skills. Another goal was to identify challenges the teachers and the students face using GIS.

Findings from the study suggest that using GIS in the classroom helps students improve their geographic knowledge and maps skills. In addition, this study found that the students' geographic content knowledge tended to improve gradually and the knowledge transferred to the subsequent lessons, while certain map skills tended to develop in a more specific manner.     

Early Instruction in Geography: An Exploration in the Ecology of Kindergarten and First-Grade Geography Education

Abstract

Student drawn maps have been relatively neglected as an evaluation tool, despite their potential utility for assessing geographic knowledge. Comparison of students' sketch maps at the beginning and end of the year can inform the teacher about how students' representations of the world change over the course of instruction. Used as a pretest, they can be used to diagnose areas of strength and weakness within a class; as a posttest they can be used to assess students' achievement and the effectiveness of instruction. In this paper we provide an easy method for sorting and summarizing sketch map data, which is illustrated using maps collected from two sixth grade classes. We also outline a framework to guide teachers in generating questions to ask about their own students' maps.     

Chile

Abstract

This study provides empirical information about the extent of geography instruction present in history classrooms. Techniques of protocol analysis were applied to oral references to geography made by teachers and students in 44 U. S. and European history lessons in several grades. The references were coded according to GENIP' s five themes plus a sixth coding category for explicit references to maps. Two types of references were found: passing references, which merely mentioned a geographic issue or feature, and substantive references, in which geography was taught or played a substantial role. That 550 geographic references occur in these lessons may explain why so many history teachers believe that they are adequately integrating geography and history. However, 75 percent of all the references were passing and not substantive. We conclude that the core epistemological events for learning and reasoning in, about, and with geography are not being taught adequately in history lessons.     

Using Road Maps in the Junior High School

Abstract

The activities described in this paper were developed to familiarize junior high school students with the variety of information available on road maps and to provide a means for practice of map skills. At Legg Junior High School in Coldwater, Michigan, students were presented with an introduction to road maps, followed by a series of worksheets to use in conjunction with Michigan and Ontario highway maps. After completing the worksheets, students participated in road rally games which required them to use maps and follow instructions and clues to find a specific location. The activities can be adapted for elementary school classes or for students with different levels of ability. Teachers might also want to increase the number of worksheets or road rallies to give students additional practice in skills in which they particularly need improvement.     

Going beyond location: Thematic maps in the early elementary grades

Abstract

Cartographic research has long suggested that preschool and early elementary children possess advanced mapping behaviors in terms of interpreting, making, and using locational and wayfinding maps. To improve instruction in geographic concepts, it is necessary to see if these advanced mapping behaviors apply to thematic or special purpose maps as well, as an understanding of these types of maps is integral to the five fundamental themes of geography. An experiment was conducted to evaluate the thematic mapping abilities of second-grade students. Students viewed maps at the neighborhood, city, and national scales displaying different types of symbolization and presented in a random order. Results indicated that the map tasks were appropriate for this age level, and a statistical test of reaction times did not identify a best symbol type or scale, as all were appropriate for this age level. Responses to discussion questions indicated the students also have the ability to describe spatial patterns. The interpretation of quantitative information on maps is within the ability level of second grade students, and materials currently used in second grade should be revised to include these maps.     

How Textbooks Influence the Curriculum in Geography

Abstract

In this study, pairs of students in fifth and seventh grade generated and answered questions based on maps. More than 90 percent of the questions they generated made sense with reference to the map on which they were based. Each of these questions was coded in terms of both its informational content (symbols, latitude and longitude, and scale) and the process by which a map user obtains the information from the map (map reading, map interpreting, map inferring). Results indicated that students most often generated three types of questions, which together accounted for more than 80 percent of all the questions: 1) read symbol, 2) infer latitude and longitude, and 3) interpret scale. Qualitatively, the questions were analyzed for what they revealed about student confusion about map content. Problems with all three aspects of map content were common among both fifth- and seventh-grade students. The problem-posing technique proved useful for evaluating student's knowledge.     

River Views of Beginning Pre-service Teachers: Content Knowledge Use

Abstract

How beginning teachers organize themselves to teach new or unfamiliar topics is an important issue for research. This paper discusses information about rivers in pre-service teachers' lessons taught to fourth grade students. Lessons were videotaped and transcribed for analysis. The data consisted of all information about rivers found in the lessons. Lesson content was analyzed for accuracy, coherence, centrality, over-simplification, and undue emphasis.

Seven kinds of problems with lesson content occurred because the beginning teachers lacked sufficient knowledge about rivers. Inaccurate information was either presented or allowed to stand unchallenged in the lessons. The lessons lacked coherence, because the beginning teachers tended to make passing references to concepts. About twice as many of the lesson concepts were peripheral to the study of rivers, the problem of centrality. The relationships between some river-related ideas were misunderstood or ignored. Both physical and human geography concepts were consistently over-simplified. The recreational use of rivers was consistently over-emphasized.     

Delmarva Coastal Bays Map Contest for Fourth Graders

Abstract

This map contest is an exercise in geographic education for fourth grade students. It is sponsored by a grassroots, nonprofit environmental organization to raise the awareness and appreciation of students to the special features of their home region. The maps illustrate some aspect of the living resources or history of the region. As a case study of the map contest, this paper describes its design, publicity, appeal to teachers, judging of entries, and role of volunteers. It considers the research on map skills among young students and ways in which the contest supports geographic education.     

Journal Writing and the Development of Spatial Thinking Skills

Abstract

Informal journal writing in freshman level World Regional Geography classes is discussed as an active learning method that helps students to develop their spatial perspective and gain a better understanding of the interconnected nature of geographic phenomena. In particular, students read about events in the world and write their ideas about the geographic nature and implications of those events. Thinking spatially and thinking critically by creating their own framework for interpreting the event and applying concepts learned in class means that students are actively participating in their own learning. Ongoing instructor feedback and assessment are essential to this learning activity and are discussed as part of this exercise.     

The Council at Work

Abstract

Through analysis of census data, these lessons cover geographic concepts dealing with migration and population change in the United States. Students discuss the historical push and pull factors of immigration to the United States. By focusing on the recent influx of Hispanic immigrants, students look at the geographic concepts of assimilation, discrimination, and time-decay. Students also create graphs and maps to examine the recent increase in the United States Hispanic population and geographic patterns of Hispanic settlement.     

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.     

Organization of Feature-, Time-, and Location-Based Mental Models

This study considers how mental models are encoded into memory by viewing visual displays like maps. A mental model is an internal representation of a situation that links objects or concepts to other objects or concepts. Previous studies indicated location-based mental models are encoded when a series of propositional statements such as the object is in the location are read from a text. Evidence that locations were being used as the basic container for an organization of mental models is provided by a significant fan effect. A fan effect shows an increase in reaction time with the number of models considered when making a decision. Features, times, and locations were considered as possible containers in the mental models. Subjects created location-based mental models, but also encoded feature-based mental models. A reverse fan effect for time, found for a map animation, suggested the order of the presentation of maps could greatly affect the structure of learned information.     

Error propagation in cartographic modelling using Boolean logic and continuous classification

Abstract

When data on environmental attributes such as those of soil or groundwater are manipulated by logical cartographic modelling, the results are usually assumed to be exact. However, in reality the results will be in error because the values of input attributes cannot be determined exactly. This paper analyses how errors in such values propagate through Boolean and continuous modelling, involving the intersection of several maps. The error analysis is carried out using Monte Carlo methods on data interpolated by block kriging to a regular grid which yields predictions and prediction error standard deviations of attribute values for each pixel. The theory is illustrated by a case study concerning the selection of areas of medium textured, non-saline soil at an experimental farm in Alberta, Canada. The results suggest that Boolean methods of sieve mapping are much more prone to error propagation than the more robust continuous equivalents. More study of the effects of errors and of the choice of attribute classes and of class parameters on error propagation is recommended.     

Stereoscopic Images From Isoline Maps

Abstract

Beginning students of geography often have difficulty understanding contour and other isoline maps. If the contours can be seen in three dimensions, this concept of surface representation is grasped much more readily. The simplest way for an instructor to demonstrate the isoline concept is to draw stereopair contour images, which, when viewed through a stereoscope, show a three-dimensional surface. Crude, but effective stereocontour maps can be drawn by anyone, regardless of cartographic skill, by using the method outlined in this paper.     

Integrating GIS into the Undergraduate Learning Environment

Abstract

Despite the promise of GIS, substantial barriers have prevented its widespread use in geographic education. Among the key factors are technical impediments stemming from software complexity, pedagogic issues related to the lack of experienced faculty and the shortage of curriculum materials, and systemic issues associated with faculty motivation. This case study describes strategies that were employed for addressing each of these barriers in a large enrollment, multisection world geography course. Successful implementation of those strategies has enabled large numbers of students in classes taught by instructors with no formal GIS experience to spend a substantial amount of time learning geography with the help of simple, easy-to-use GIS software applications.     

Comparisons of Conventional “Subdued” to Vivid “Highly Contrasting” Color Schemes for Elementary School Maps: Report of An Experiment

Abstract

The appropriateness of color schemes commonly used on maps for middle grade children has been inadequately researched. Most contemporary designs seem based more on adult conventions than on investigations to determine the factors that make maps interesting and readable to children. Based on four specially-prepared maps and 384 interview sessions with subjects enrolled in fourth, fifth, and sixth grades of a public school system, the findings of this study provide some clear implications for those who either design or purchase maps for classroom use.     

Notes

Abstract

The concept of correlation is becoming increasingly important to students of all ages as the use of electronic data base technology becomes more common. Data maps offer a significant and new format for secondary students to use along with tables of values and scatter plots as they learn and apply the correlation concept. Data maps are particularly effective in promoting the interdisciplinary treatment of important content by allowing students to interpret social or physical relationships within the geographic context in which they arise.     

The Geography Course in the Oswego State Normal and Training School

Abstract

This article addresses the knowledge of geography and geography-related careers of sixth and ninth grade students in six Florida schools. For geography knowledge no sex differences were noted for the total sample, ninth grade African American males outperformed African American females, achievement differed by school, and students knew most about skills and least about physical geography Students' career knowledge increased with grade level; males were more knowledgeable than females; African American females were the least knowledgeable; sex-related differences became more pronounced in ninth grade; and the most frequently cited careers were cartographer, explorer, meteorologist, and news person.     

World Patterns of Geographic Literacy Based on Sketch Map Quality

This paper discusses world patterns of geographic literacy and illiteracy based on the quality of sketch maps of the world drawn by university students in first-year geography classes. The study, sponsored by the International Geographical Union and funded by the National Geographic Society, contains 3,568 sketch maps of the world collected from 75 sites in 52 countries. For the purposes of this paper, geographic literacy is equated with the number of nations and continents included on the sketch maps. The individual map scores are aggregated to determine the average number of items per map for each site and nation. Our set of maps provides a baseline of world variations in geographic literacy just prior to the end of the Cold War. The sketch map techniques can be used to monitor changes in geographic literacy.
