7. Conduct short as well as more sustained research projects based on focused questions, demonstrating understanding of the subject under investigation.
8. Gather relevant information from multiple print and digital sources, assess the credibility and accuracy of each source, and integrate the information while avoiding plagiarism.
9. Draw evidence from literary or informational texts to support analysis, reflection, and research.Here are three more Common Core anchor standards for writing. These focus on what goes into the writing, expecting students to gather and organize evidence, rather than just invent their pieces by imagining or imitating adult debates. They build on the three kinds of writing (argumentation, explanation, and narrative) and the three skills for producing and distributing those writings, and again, I think they're the right thing to work on.
Standard 8 is especially valuable. Assessing sources has always been key to well-informed citizenship, and it's become even more important as the Internet makes so many texts available with so little filtering for quality. The next generation will need to be able to use those resources wisely, and Common Core calls for us to equip them to do that well.
You can download the complete Common Core State Standards here. They were developed by organizations of governors and chief state school officers like Kentucky's Commissioner of Education, and they've been adopted by 46 states (47 for the mathematics standards).
