Tools to Help Writers Explain Good Evidence

SarahT-headshot-130By Sarah Tantillo with Jamison Fort

In Part I of this two-part series, I wrote about how we can help students rule out ineffective evidence when they are attempting to build arguments. The flip side of this work is to help them find the best evidence. In this post, I’d like to share a tool  teachers can use to do just that.

To give students more practice in finding relevant evidence on their own and explaining it, my friend Jamison Fort, who teaches 6th and 7th grade social studies, created the following organizer for students to analyze one text that has multiple claims. (We use “claim” and “argument” interchangeably.)

The rest of Jamison’s lesson

The day after this exercise, Jamison explained that the ultimate goal was to make sure that by the end of the next three days, every student would be able to evaluate evidence and choose the strongest possible evidence to support a claim. Then he launched the following lesson:

Their answers—that the evidence must be relevant or related to the claim, or must prove a point—showed that they evaluated evidence with single isolated indicators in mind. They had a partial understanding with responses that outlined segments but missed the full process.

To expand their understanding of how to select effective evidence, Jamison turned to this activity: Students paired up and compared and contrasted the quotes they had chosen, then answered the following questions:

Jamison then told his students they were only allowed to keep the four most valuable characteristics of effective evidence. His students then decided what could be eliminated or synthesized and what needed to stay. Once four characteristics were determined, Jamison challenged the class to create an evidence evaluation checklist. Here is what they produced:

Students became highly animated in challenging his assertion, asking him to “explain his logic.”

He told them he didn’t need to explain his logic, adding, “I just know I’m right.”

Jamison could see his students’ frustration; they clearly knew he was wrong but couldn’t express how they knew. This was how he pushed them to use the tool they had just created. He wanted to show rather than tell them of its value.

After a moment of this student-teacher standoff, he diverted their attention back to the poster they had just created and asked them again, “Is there no one who can tell me why I am wrong?”

And then the connection was made, that “aha” moment. A girl who had taken up the role of class spokesperson said his answer was wrong because it didn’t meet all the necessary checkpoints: “It was related to the text, but not relevant to your claim.”

Once kids have the essentials, do some practice

Once you’ve helped students grasp the essential characteristics of effective evidence, they can practice analyzing multiple texts, identifying arguments and key evidence. Here is a tool for that:
