Abstract
Researchers have raised concerns about teachers’ ability to embed nature of science (NOS) in their science instruction, a complicated situation that is certainly impacted by the availability of adequate resources to assist K-12 science teachers. In light of the implementation of the ideas from the Framework for K-12 Science Education and the Next Generation Science Standards in the USA, this study sought to identify and evaluate resources aimed at guiding NOS instruction. A search of the National Science Teachers Association (NSTA) database for Next Generation Science Standards (NGSS)-aligned instructional resources resulted in an analytical sample of eight lessons. All materials accompanying these lessons were analyzed for their representations of 10 NOS aspects. The evaluation of these materials revealed a prevalence of implicit, naïve representations in the sample lessons (60.4% of all NOS aspects addressed). Examination of the connections to NOS in these lessons leads to a set of recommendations to improve the quantity and quality of NOS representations in future NGSS-aligned instructional resources. The analytical approach used and the issues raised about the presentation and treatment of NOS in precollege lessons are of interest to the broader science education community.

Notes
The term “inquiry” is largely absent from the Framework and the NGSS. Anderson (2016) explained that the range of meanings ascribed to the term and its narrow interpretation (equating use of the term inquiry to “The Scientific Method”) in American precollege settings as contributing to this shift.
The NGSS@NSTA curators include both classroom teachers and NGSS writers identified through a competitive application process. They receive regular training and use the EQuIP rubric to evaluate resources and offer exemplars of both the kinds of resources American educators now need and the process by which educators can take existing materials and adjust them to support NGSS instruction (NSTA, 2014).
Connections between specific performances expectations and NOS can be seen when reviewing the NGSS in text (NGSS Lead States 2013) or online (e.g., www.ngss.nsta.org); however, these connections would not relate to a specific resource, contain limited information to help teachers convey these NOS ideas, and require additional effort on the part of the teacher.
