The document discusses teaching and assessing the 4Cs (communication, collaboration, critical thinking, and creativity) using Common Core standards. It provides examples of CCSS standards that imply the 4Cs and suggests having teachers examine standards in teams to identify relevant language. The document advocates for assessing the 4Cs to encourage their development in students, noting that assessing communication and collaboration is already common. Sample self-assessment and peer assessment methods for project-based learning are outlined, including journals, reflections, feedback, products, organizers, observations, and explanations.
