ArticleAn interview with Sharon Hessney
As part of this year’s Massachusetts Civic Learning Week, the Leventhal Map & Education Center will co-present a virtual session called “What’s Going On In This Graph?”: Maps and Data for Civic Literacy with Sharon Hessney on March 7 at 3:30PM.
Sharon Hessney is an award-winning math teacher from Boston Public Schools and the “curator,” writer and moderator for The New York Times Learning Network’s “What’s Going On in This Graph?” This free, weekly online feature has been published for six years and has had more than 50,000 online student responses. Sharon has worked with the Leventhal Map Center K-12 education team to develop several high school statistics lessons that used maps and graphs from the 2017 Map Center exhibition Who We Are: Boston Immigration Then and Now.
“What’s Going on in This Graph?” is a free, weekly online feature where students are invited to share what they notice and wonder about different graphs, maps and charts previously published in The New York Times. On Wednesdays, there is a live moderated discussion with math teachers and students from around the world. By Friday, a free link to the article that included the graph and additional resources is revealed. Many teachers use this feature as either a “bell-ringer” at the start of class each week or to teach an entire class period. The feature is not only used in math classes but also in science and humanities classes where students are learning how to present claims and supporting evidence. All students from all backgrounds can participate as they are asked “What do you notice?” and “What do you wonder?” about the graphs. Understanding of the maps and graphs and the topic grow as students bounce their insights off each other.
Michelle LeBlanc, K-12 Director of Education for the Map Center, took the opportunity to talk with Sharon about her work with The New York Times Learning Network and her enthusiasm for the power of maps and other data visualizations to help students make sense of a variety of different issues and events in their world.
The text of this interview has been lightly edited for clarity.
I liked reading newspapers, rather than books, when I was young. For twenty years when teaching, I would share newspaper graphs with my students. In The New York Times Learning Network, I saw that there were humanities-focused features, such as “What’s Going On in This Picture?” and I wanted to do something like it for math. When the American Statistical Association became involved with The New York Times, I suggested we could do what I had been doing with graphs in my classroom. Now, having some of the best newspaper graphs and maps for students to discuss is available to anyone online.
Graphs use data and space to display “stories.” Lists of students and their grades are just data in a chart. If I were, for example, to categorize the grades by course or class period and displayed this in a segmented bar graph, showing the relative size of each of the groups, that could be a graph since the bar segments lengths show the space.
Maps, by definition, are about space. Data can be superimposed on a map by showing data values with different colors. (This is called a choropleth map.) By observing where the colors change, you can absorb the data faster than if you tried to read a table of numbers or even numbers on a map. Bubble maps (maps with filled-in circles superimposed) are particularly effective in conveying at least three variables by their location, size and color.
I have four learning objectives for students when I use graphs:
Here are two “What’s Going On in This Graph?” releases with maps:
There is much to notice and wonder about the location and size of the regions of climate risk. Note that the “top” climate risk is shown. Any region can have more than one significant climate risk. Recognize the climate risks for regions of greatest population density and regions with greatest risks and least resources to address risks and their effect.
There is much to notice and wonder about the amount of military spending and the amount of military spending per capita. Examine broad regions of the world that have the most spending. What surprises you from this bubble map? Notice and wonder about the nine additional graphs from the article.
The archive of the 147 released New York Times graphs is on the “What’s Going On in This Graph?” website. Click the graph title to see the entire release and follow up reveal, which includes the free link to the New York Times article that included the graph, additional questions and Stat Nuggets, concise definitions of statistical and math terms from the graph and an explanation of how they are used.
