The Promise and Practice of Teaching Data Literacy in Social Studies: A Companion Site Main Menu A Taxonomy of Data Visualizations Information can be visualized in multiple ways, from bar graphs to scatterplots, choropleth maps to distribution maps, timelines to time series. Designers can choose from an array of graphical elements such as points, lines, or icons used to represent data, and multiple aesthetic attributes such as color, shape, and size. Furthermore, designers can apply multiple combinations of titles, legends, and explanatory text to provide context for a data visualization. Given the almost dizzying array of data visualizations students may encounter in social studies, it is helpful to place them in categories related to the types of questions they will help us answer. Data Visualizations as Primary Sources Humans have been creating different types of data visualizations for centuries. Explore this collection of timelines, maps, graphs and charts to see what they reveal about the historical time and place in which they were produced. How do students learn with data visualizations? Reading data visualizations in print and online social studies texts can improve students' overall comprehension and quality of reasoning. And there is evidence to suggest that reading data visualizations helps students better understand historical and geographic context, multiple causation, and change over time — all important concepts for students to grasp in social studies subject areas. However, students may face significant challenges in trying to make sense of different kinds of data visualizations. This section provides insight into both benefits and challenges of reading timelines, maps, and graphs and charts. How should students analyze data visualizations in social studies? The challenges that data visualizations present, coupled with their prevalence in social studies texts, standardized assessments, in online social studies resources, and as sources of information in society, suggest that teaching with and about data visualizations in social studies is essential. This module provides guidance for how teachers can support students' data literacy for social studies. How do I help students create and integrate data visualizations for social studies? This page highlights several tools that are useful for data-based projects in social studies. And accompanying each tool is a "minimal manual" that provides guidance for using the tool in social studies inquiry- and project-based learning.

Map of Territory of United States from the Mississippi to the Pacific Ocean; Ordered by Jeff'n Davis, Secretary of War to Accompany the Reports of the Explanations for a Railroad Route (1858) Carrie Finholm Dating back to 1858, this is a map that presents the territory of the United States from the Mississippi to the Pacific Ocean to help support the explorations for a railroad route. Ordered by Jeff'n Davis--the Secretary of War--the map was made in accordance with the 10th & 11th sections of the Army Appropriation Act of March 3rd, 1853. At the bottom of the map, there is a scale to show the statute miles. This copy was annotated in color to show Indian reservations and military departments. The red and brown flags represent the military establishments. Relief is shown by using hachures and spot heights. The map also shows Indian tribal locations, military posts, routes, and dates of expeditions. The bottom right hand corner includes a list of authorities.

Willard's Chronographer of American History (1845) Carolyn Corey This educational wall map created in 1845 summarizes the history of the United States in the form of a tree. Time is represented using the metaphor of a clock, circling in a timeline around the treetop. The graphic covers the period from Columbus's "discovery" in 1492 until the present. With this format, emphasis is placed on historical context of one event compared to another; to know the relative place of an event in history compared to others.

Sanson Map of the World on Hemisphere Projection (1659) Carolyn Corey Nicolas Sanson d'Abbeville was a celebrated Paris cartographer. This map created in 1659 gives an overview of the general divisions of the globe. The topography of the landmasses fades into the background, although it contains a few curiosities. For example, Korea and California are shown as islands. In the foreground the two hemispheres show the system of meridians, latitudes, equator, tropics, and climatic zones, which served the contemporary geographers as divisions and description of the surface of the Earth. The title of the map indicates that the coordinate system also correlates to the division of the imagined celestial sphere, which astronomers used to map out the position of celestial bodies.

Plan of Fort Henry and its Outworks (1862) Carrie Finholm The Battle of Fort Henry which was fought during the American Civil War on February 6th, 1862 and was a very important victory for The Union. Fort Henry was known as a critical defense point for the Confederacy as it protected Nashville, Tennessee and the railroad route between Bowling Green, Kentucky and Memphis. Fort Henry's surrender also allowed the Tennessee River to open to the Union traffic south of the Alabama border. Established by the United States Army, the map displayed is upon cloth with pen-and-ink. The profile of the fort, the ditch full of water, and the profile of the rifle pits are also featured on the cloth map.

Map of the Battle Field of Gettysburg (1863) Carrie Finholm The Battle of Gettysburg, which involved the largest number of casualties of the entire Civil War, was known as the war's turning point. Right after the battle, this map was made in 1863 to showcase the Battle of Gettysburg. This particular map was based off of Gouverneur K. Warren's map of the Gettysburg Battle Field, but with the addition of hachures. The names of land owners are printed in the color red. The troop positions are not noted.

Universal Cosmography (1507) Carolyn Corey This map is a key work in the development of scientific geography. There is only one surviving example of this woodcut, which is made up of 12 individual pages. The German cartographers Martin Waldseemüller and Matthias Ringmann decided to call the new (to Europeans, at least) continent in the west "America," after the first name of the seafarer Amerigo Vespucci. This unusual visualization came about because Waldseemüller extended Ptolemy's second projection (which was conceived for a smaller circumference of the Earth) in order to integrate the Pacific Ocean and North and South America. At the top, Ptolemy and Vespucci are pictured.

Locations and Wanderings of the Aboriginal Tribes (1828) Carolyn Corey The American pedagogue Emma Willard strove to reform educational methods. In addition to founding her own schools, she published teaching materials, such as Willard's History of the United States, or Republic of America, which was accompanied by an atlas of 12 maps. In the preface she emphasized how vital it is to convey to students a stable framework for understanding complex themes. The clear arrangement of facts and visual devices should make it possible for students to acquire and categorize further knowledge at a later time. This example shows the historical state of North America before European colonization. The locations of various tribes of aboriginal peoples are illustrated, shown on the map as ovals, with their migrations and movements indicated by lines and arrows.

Conspectus of the History of Political Parties (1880) Carolyn Corey Timelines began to gain popularity in the nineteenth century and became very prominent in everyday life. This “Conspectus of the History of Political Parties” helps to consolidate political history into one data visualization. A “conspectus” is a term from the 19th century, meaning “a comprehensive mental survey.” In this data visualization, the various presidencies are outlined at the top by year and color coded in accordance with the outlined political party “rivers” at the bottom, as well as other important members of the cabinet, the Supreme Court, and other federal political positions. These demonstrate the power held by each political party based on the thickness of the river. Scattered throughout the timeline are various events that occurred, weaved throughout the rivers. This was created by Walter R. Houghton, published by Grander, Davis & Co. in 1880, and lithographed by William B. Burford in Indiana.

Plan of the Investment of York and Gloucester (1782) Carrie Finholm Sebastian Bauman-- the creator of this map-- was a topographical engineer who immigrated to North America from Germany. He designed and created this map very shortly after the Battle of Yorktown when the British surrendered. This was the very first map published that was dedicated to the battle and to the famous general, George Washington. The plan illustrates the British troops in red. The French and American troops are colored in yellow and blue. The passage at the bottom of the map contains the description of the battle.

New York and Erie Railroad Diagram (1855) Carolyn Corey This diagram comes from the early days of the railroad and shows the organizational structure of the New York and Erie Railroad Company. Like many early rail companies they had the challenge of securely managing the traffic going in both directions on single tracks and avoiding deadly collisions. Those responsible for the lines in the company used the telegraph to exchange current traffic information. The diagram illustrates the strict lines of communication that had to be observed to prevent fatal mistakes. The long main branches of the diagram represent the fives lines of the railroad company, which are rooted in the circular structure of management. The numerous round leaves on all the various branches stand for individual employees.

Map Showing the Distribution of Wealth (1874) Carolyn Corey Based off the ninth census conducted in 1870, this map displays the distribution of wealth within the United States. With the help from Francis A. Walker and information from the United States Census Office, data was able to be collected to display this information. A scale is provided on the right hand side to reveal what the colors of wealth represent. The bottom center contains an explanation of some of the key features of the map. According to the map, the blue lines indicate the boundaries of groups of population. The figures in blue express the the number of inhabitants to the square mile found in each group. The map also explains in the description below that the shaded lines in blue reveal the outside limit of a population of 2 or more to the square mile. The shading points towards the regions which have a population of less than 2 to square mile. This image can be found at https://www.loc.gov/resource/g3701gm.gct00008/?sp=83.

Whereon is Laid Down the Missouri, Jeffersons, Lewis's, Clarks, and the Columbia, Rivers, from the Mississippi to the Pacific Ocean (1807) Carrie Finholm After the Louisiana Purchase, Lewis and Clark were sent on an expedition to explore the western portion of the United States. This map, created by Meriwether Lewis himself, portrayed the journey that him and William Clark took. The map specializes in the northern quadrant of the United States from east of the Mississippi River and to the Pacific Ocean. The red ink was used for indicating and locating territories of Indian tribes. The black ink was used for inscriptions, place names, for both latitude and longitude, and for borders. The blue was used to display sources of water such as rivers, lakes, and the ocean. This image can be found at https://www.leventhalmap.org.

The Discovery of the East Coast (1856) Carrie Finholm This map dispenses almost completely with representing geographic features. Here German travel writer Johann Georg Kohl visualized historical explorations along the east coast of the United States. This and two other maps, which show the Gulf of Mexico and the Pacific coast, belong to a monumental study that Kohl carried out for the U.S. coastal and Geodetic Survey. In this hand-colored map the coast is traced with differently colored lines, each standing for an expedition. Unfortunately the range of colors does not logically correlate to the successive periods of time. This map is however notable in its goal of creating a visual representation of the series of expeditions and the ever increasing knowledge that resulted.

Reynold's Political Map of the United States (1856) Carrie Finholm This map was designed to display the comparative area of free and slave states and the territory open to slavery or freedom by the repeal of the Missouri Compromise. This map depicts free states in red, slave states in black, and territories in green. Kansas is intentionally left neutral to emphasize that the fate of that state was in question. This map is persuasive, attempting to convince viewers that free states in the Northeast were in danger of being overwhelmed by “Slave Power” in the South. There are multiple charts of statistics at the bottom of the map, based on the Census of 1850. They convey the message that the southern states were able to advance their agenda because they had more power at the federal level, even though on demographic, cultural, and economic measures, the North was superior.

Acres of land owned by Negroes in Georgia (1900) Carolyn Corey The creator of this visualization--W.E.B. Du Bois-- was a sociologist and well-known leader in the black civil rights movement. For the World's Fair in Paris in 1900 he designed an exhibition on the black population in the United States with his former classmate Thomas J. Calloway. In just four months, and with financial support from the U.S. Congress, Calloway and Du Bois produced a presentation comprised of a great number of books and photographs. Du Bois's particular contribution together with students, was to prepare several dozen display boards presenting sociological data on the lives of the black population through graphs and charts. It is clear that Du Bois modeled some of the charts from statistical atlases at the U.S. Census Office, for example; in others he developed his own modes of visualization. This particular data visualization displays information of how many acres of land was owned by negroes in Georgia from the year of 1874-1899.

The Complete Map of Richmond and its Fortifications (1863) Carrie Finholm Th city of Richmond, Virginia served as the capital of the Confederacy during the American Civil War. As it was of central importance both strategically and politically, the city was one of the most important targets of the Union army over the course of the war. This situation is represented in this map, which was published in Boston. It shows the city's surroundings, with residential areas, rivers, swamps, and roads. Around the city, the Confederate defensive positions and their striking distances are charted. The early use of concentric circles for indicating distances is especially interesting, as is the note in the title attesting to the accuracy of the information--even though it was published in the North it originated from an engineer who deserted the Confederacy.

Population of the United States from 1790 to 1820 (1874) Carrie Finholm With its numerous diagrams and thematic maps, the Statistical Atlas of the United States, published in 1874 by Francis Amasa Walker, is a masterwork of the 19th century statistical graphics. This example shows the "progress of the nation" in a series of four maps that document the population growth in 10-year stages from 1790 onward. The population densities of the inhabited territories (excluding indigenous peoples as they were not taken into account in the censuses) were broken down into five classes. In addition the authors made great efforts to calculate the respective geographic "Centre of Population," evidently because this concept played an important role in the public debates of the time. Represented by a star, this center wandered from the northern Chesapeake Bay in 1790 steadily westward over time.

Stowage of the British Slave Ship Brookes (ca. 1790) Carrie Finholm This visualization is considered iconic of the anti-slavery movement that formed in the late 18th century Great Britain. This work is attributed to the English abolitionist Thomas Clarkson who tirelessly collected and published reports and records of the inhumanity of the slave trade. The artist who rendered the illustration is unknown. There were many variations of the graphic and it found broad distribution as a single printed page and in newspapers. It shows various sections of a transport ship and the "stowage" of enslaved people in the lower deck. Special attention was paid to the extreme lack of space that was allotted to each person for a trip that lasted many weeks.

United States Political History (1883) Carolyn Corey Scribner's Statistical Atlas of the United States was published privately, but was based on the data from the 10th census of 1880. In addition to the numerous statistical maps and diagrams, it includes charts on political history. The page shown here traces the political evolution of the United States through the changing parties in power. Three horizontal sections present a timeline starting from the first U.S. presidential election in 1789 to the then present day. The height of each area of color correlates with the number of votes. It is color coded according to the respective party in power and each section represents a presidential term. The text gives information on the prevailing political themes of each presidency.

Historical Geography (1888) Carolyn Corey This work demonstrates impressively how maps have been used beyond their original purpose for the communication of political content; here, for example, offering an interpretation of U.S. history through a moral lens. The territory of the United States is overlaid with two strange trees oriented horizontally from east to west. As the rhetorical explanation states, this map deals with the two main influences on American history since the founding of the original colonies of Jamestown and Plymouth. The "good tree" of the North is rooted in the Bible and brings light to the West, where it ends in "immortality" in the Pacific. The dark and crooked tree of slavery in contrast soon buckles under, ending in "murder," "war," and finally "Hades," which is, without further explanation, located in Texas.

Map of the United States, showing by colors the area of freedom and slavery, and the territories whose destiny is yet to be decided : exhibiting also the Missouri compromise line, and the routes of Colonel Fremont in his famous explorations : with importa Mark Guzdial Published as a campaign poster supporting the Republican Party's first presidential bid in 1856, this broadside provides a commentary on the geographical sectionalism that was polarizing the nation. Using 1850 census data, it tabulated the demographic and economic differences between free and slave states, highlighting political concerns that the balance of Congressional power would shift as newly acquired western territories were admitted as states into the Union. The map clearly marked the 1820 Missouri Compromise line, which had defined the boundary between free and slave states. However, the passage of the 1854 Kansas-Nebraska Act nullified this long-standing compromise line, and potentially opened the entire western territory to slavery because it sanctioned “popular sovereignty“ whereby citizens of each territory could vote on the slavery issue.
