A key instructional change recommended by the "Next Generation Science Standards" ("NGSS") is for teachers to be more explicit and systematic in teaching students science and engineering practices in addition to crosscutting concepts because the NGSS include a stronger focus on seamless teaching in three integrated dimensions (Duncan and Cavera 2015). In addition to teaching students about scientific ideas in which they use a model, it is now also important to explicitly teach the practice of scientific modeling (Lehrer and Schauble 2000). This article highlights three-dimensional (3D) science teaching and learning by offering specific examples from a 3D lesson.
