CORROBORATION: PUTTING THE PIECES TOGETHER
Interpreting primary sources is an ideal method to access multiple stories, and corroboration is the process by which students pull
the pieces of research together. Daisy Martin describes the beneît of using multiple accounts, noting, âshifting from thinking about
one story to multiple stories is an elegant and useful way to pivot from history as înished, certain, and simple to history as complex,
interpretive, and procedural.â
12
In corroboration, students move from evaluating one source in isolation to synthesizing across
multiple sources where the thinking and questioning become more complex. Teachers should provide prompting questions to probe
how the sources relate to each other. Students will beneît if they can practice this skill in a collaborative structure. Corroboration
promotes deep thinking that will facilitate original research on the part of the student historian.
The thinking that happens in corroboration is multifaceted. Not only do students synthesize information, but they also begin to
question the reliability of independent sources as various perspectives emerge. They may confront conîicting evidence and
consider why there are multiple accounts or opinions. They may also begin to see consistent trends or emerging themes. When
students work with nonîction texts, they tend to assume the source is always accurate. Beers and Probst dispel this notion and
deîne nonîction as a âbody of work in which the author purports to tell us about the real world, a real experience, a real person,
an idea, or belief.â
13
They further advise that âour job as readers of nonîction is to enter into that potentially messy reading as a
co-constructor of meaning.â
14
Developing the ability to co-construct meaning through corroboration requires critical thinking. Mary
Ehrenworth describes shifting the readerâs experiences and suggests teaching that nonîction is âsomeoneâs perspective on the
truth.â
15
In corroborating sources, students analyze varying perspectives, which cultivates independent thinking.
Students need support to confront the cognitive challenge of synthesizing multiple sources.
16
Using an organizer that identiîes each
sourceâs critical claims is a method in which students can step back, compare and contrast, and view the big picture. Looking at each
sourceâs succinct analysis will allow students to evaluate how they speak to each other. In this process, they will learn to ask more
complex thinking questions that consider how the sources relate. Possible prompting questions include:
⺠Has this text made me see something diîerently?
⺠Does this text oîer an opposing view? Do these sources validate each other?
⺠Does this validate my thinking? Why or why not?
⺠Do I need to do more research to îgure this out?
⺠What new questions should I research? What else do I want to know?
After students identify the key claims and answer some of the questions, they should discuss these corroborating questions in
small groups where their thinking will be visible. In collaborative discourse, students are more likely to understand complex material
and engage more deeply with the content.
17
All students beneît when they have to articulate their thoughts and hear the ideas
of others. Students may validate their thinking through the discussion process, consider a diîerent interpretation, or defend their
understanding of multiple sources.
Corroboration requires analytical thinking that fosters a deep understanding of a group of sources. This thinking must occur
throughout the research process, not only toward the end. In addition to helping students pull their ideas together, it may also help
them create new research questions for an even deeper dive into the topic. Digging deep with more complex questions will enhance
the level of analysis in the end research product.
ACTIVITY ALERT!
In Activity Three, students will practice corroborating two sources. Ideally, corroboration would occur after students
have read and established historical context. Before starting this activity, students will need to complete the Historical
Context Organizer (introduced in Activity One) and use the Close Reading Routines (from Activity Two) to read the
speeches closely. Students will work in groups to complete an organizer to prepare for a full class discussion on
corroborating questions.
