California counties and school districts are implementing a critically needed change in how they evaluate science instructional materials before investing in local adoption. Past adoptions were often too superficial in nature, focusing on candidate materials' overall look and feel, use of graphical elements, and availability of ancillary materials while insufficiently attending to the substance of the materials for high-quality teaching and learning. In contrast, the California NGSS Toolkit for Instructional Materials Evaluation (hereafter referred to as TIME) process enables participants to use evidence-based measures to choose materials aligned to the Next Generation Science Standards (NGSS) that meet their district's needs.
This 11th report in the NGSS Early Implementers Initiative evaluation series is intended for school and district administrators, leaders of science professional learning, and state policymakers. It provides an overview of the full TIME process, including participants' perceptions, a detailed description of the statewide TIME trainings of 2018-19, and a vignette that illustrates a portion of the TIME process.
