This curriculum, from the NOAA Ocean Data Education (NODE) Project, incorporates a scaled approach to learning. Each module offers activities at five different levels of student interaction, sometimes referred to as Entry, Adoption, Adaptation, Interactivity, and Invention. The early levels are very directed and teacher-driven, which provides important first steps when learning something new. The levels of Adaptation through Invention are more student-directed and open up opportunities to design lessons featuring student inquiry.
