Texas Essential Knowledge and Skills for Science

Teacher's field guide

What Students Need to Do: Students pay attention while a classmate explains an observation or idea. They name the facts that support the idea, then respond politely with a question or comment.
What Mastery Looks Like: A student can repeat a classmate’s main idea and point to an observation that supports it. The student waits to speak and responds without insulting or interrupting.
Common Misconceptions: Students may repeat every detail instead of choosing evidence that supports the idea. They may say “I agree” without explaining why, or think respectful disagreement is not allowed.
How to Assess It: In pairs, have one student explain why a classroom object will sink or float. Ask the partner to name one piece of evidence and ask one polite question.
