Writing conclusions

Science Practices: Writing Conclusions

This page provides webinars and resources related to writing explanations using the Claims, Evidence, Reasoning (CER) Framework. 

Once students analyze their data, it is time for them to use those data to write an explanation/ conclusion. While this can be a daunting task, many teachers have found the Claims-Evidence-Reasoning (CER) Framework can help students write a succinct, clear, and accurate conclusion to their investigation. In this Framework, students answer their investigational question (claim), support their answer with data from their investigations (evidence), and utilize key science ideas to explain the link between the evidence and claim (reasoning). 


In this webinar, David Bydlowski discusses writing explanations, using CER (Claims, Evidence Reasoning), and the connections to NGSS.

In this webinar Rebecca Katsh-Singer, Curriculum and Instruction at Boston College focuses on strategies for using the CER Framework with middle and high school students as they write conclusions, and on additional applications of this Framework as students discuss and critique each other’s conclusions.
