Maps has been treated as an essential learning element in geography education that inquires all natural and human phenomena that appear on the earth surface. Therefore, maps in all textbooks need to be provided precisely to students in a form that complies with cartographic principles. However, there have been a number of previous studies in which textbooks of middle and high school textbooks are presented in a form that does not comply with these cartographic principles. Nonetheless, there is no case study on how maps created without cartographic principles specifically affect students' understanding of geographical facts. The purpose of this study was to investigate the effects of maps that do not comply with cartographic principles on geographical understanding.
The research was conducted by using questionnaires composed of simple questions for geographical facts of high school students using the maps in high school textbooks in terms of world map representation and thematic map design. Then, the process of judging the geographical facts was specifically investigated through the individual interview process with the students. The main results of the study are as follows. First, the area recognition was very inaccurate when using the projection which is not suitable for thematic mapping, and in the case of the oval-shaped world map without lines of longitude and latitude, confusion occurred in recognizing the direction from the map. Second, Students have difficulty in understanding geographical facts from chropleth maps and isarithmic maps, which do not follow the principle of color arrangement scheme, choropleth maps, which do not use the figures important to understanding mapping data as a basis for classification, and choropleth maps that represent the total value rather than the normalized value. This study is academically meaningful because it demonstrates the necessity of compliance with cartographic principles when designing thematic maps. Also, the results of this study will provide useful information for specifying textbook compilation standards in future.
