Next Generation Science Standards.From Education Week: Well before the Next Generation Science Standards became final last month, teachers in pockets around the country were already exploring the vision for science education espoused by the document and bringing elements of that approach to the classroom. The new standards call for bringing greater depth to K-12 students’ understanding of the subject and asking them to apply knowledge through the practices of scientific inquiry and engineering design, among other elements. “The teachers say they are already changing instruction, changing how they look at content, how they plan for investigations and activities,” said Diane E. Sanna, the director of curriculum and instruction for the 1,900-student Tiverton, R.I., district, where a group of teachers has been engaged in professional development, drawing mainly on the National Research Council framework document that was produced to guide the standards.
