The National Science Teaching Association brings the Best STEM books which offer endless opportunities for engaged learning. They invite students to see the world differently and to think in new ways about what they observe. We have chosen titles that provoke readers to examine the “thinking stance” of characters—not simply to look at actions and results. Best STEM Books winners explore problems and possible solutions in the scientific world and, where applicable, in the lives of the protagonists. Instead of focusing on specific content, the Best STEM Books emphasize real-world issues that cross disciplinary boundaries.
