What This Standard Means
What Students Need to Do
- Students examine who created a source, when it was made, why it was made, and what evidence it gives. They ask questions that help decide whether the information is trustworthy.
What Mastery Looks Like
- Students can explain why a source may be dependable, limited, or biased. They support their judgment with details about the creator, purpose, date, audience, or evidence.
Common Misconceptions
- Students may assume every primary source is accurate and every secondary source is less trustworthy. They may confuse popularity, polished design, or strong opinions with reliable evidence.
How to Assess It
- Give students a diary entry and a textbook paragraph about the same event. Ask them to write two credibility questions and choose which source better answers one historical question.
