Purpose Dorothea Lange was one of the first US documentary photographers, and she was empowered by the belief that seeing the effects of injustice, in photographs, could elicit social and political reform. She famously documented the plight of Dust Bowl migrants during the US. Great Depression and harsh difficulties endured by incarcerated Japanese Americans during the Second World War. Lange’s photographs brought suppressed issues of class and race to the surface, depicting those impacted by national tragedies into recognizable, honorable, determined individuals. By showing Americans how suffering and injustice look in real life, she stimulated empathy and compassion. This inquiry is not particularly about the Great Depression or Japanese Internment, though disciplinary concept lessons would certainly support students’ prior knowledge. This lesson focuses students’ attention on broader ideas regarding social justice and how social and political documentary photography transform people’s views about distressing problems, even today. Supporting questions are: How can deep analysis of photographs affect our thoughts and emotions about social issues? What is empathy? How can social documentary photography affect people’s emotions? Supporting questions guide students to answer the greater compelling question, How can visuals, such as photographs, impact social change? The paper aims to discuss these issues. Design/methodology/approach This is an inquiry lesson plan based on a National Council for the Social Studies Notable Trade book for Young People award winner, Dorothea’s Eyes, written by Barb Rosenstock. Findings The paper is a lesson plan, which incorporates students’ analyses of primary sources and other research methods to engage the learner in understanding how Dorothea Lange helped change perspectives regarding the need for social and political reform. Though the story is historic, similar social justice topics still persist, worldwide, today. Originality/value Through inquiry and research, students begin to learn how social and political documentary photography began in the USA, and students create their own social documentaries. Though the US Great Depression and Japanese Internment are highly relevant within this lesson, the overall, greater message is about class, race, suffering and how to inspire empathy.
