STEM is not just about learning four discrete subject-specific content areas (McClure et al., 2017), but also an approach of higher order thinking (i.e., the ability to think critically, logically, and creatively, and solve problems; Baharin et al., 2018). In this article, the authors use STEM learning to describe children's learning about STEM, which they define as a combination of STEM content knowledge and STEM thinking (i.e., the use of higher order thinking skills related to STEM; Lapek, 2018). The authors also define a STEM learning opportunity as a situation where children have opportunities to learn about STEM content knowledge and thinking. These situations may be naturally occurring and/or with guidance from an adult. This article describes what STEM learning looks like for infants and toddlers. It includes examples of STEM learning opportunities for infants and toddlers within daily routines and activities. The authors also share a coaching framework to help early intervention providers support families to embed STEM learning opportunities at home.
