DCIs, SEPs, and CCs, Oh My! Understanding the Three Dimensions of the NGSS


"Taken together, the DCIs, SEPs, and CCs represent a markedly different way of teaching science. Can one use existing lessons to teach in this way? Not really. Most existing lessons that claim to be 'inquiry-based' do not truly engage students with building knowledge of DCIs through engagement with SEPs and CCs. The new standards provide a different view of what it means to do and learn science. Understanding the three dimensions is an essential first step in the process of becoming a 'next generation' teacher."
