Children try to understand, make sense of, and influence the world around them. As they do so they develop explanations of how the world works—explanations that may be sophisticated, but do not align well with those accepted by science (Inagaki, K. & Hatano, 2002; 2006). Young children regularly engage in complex reasoning even before they enter school, developing their own ideas about how things work (Metz, 1995; Carey, 1985; Gelman & Kalish, 2005). Skilled teachers listen to what students say and observe what they do and then incorporate students’ ideas into their instruction, enabling students to construct their knowledge based on direct past experiences. By scaffolding and creating learning progressions, teachers enable students to create ever more sophisticated explanations of their world (NRC, 1999).
In creating DASH, Pottenger, et al., (2000a, 2000b, 2000c) developed learning sequences beginning in Kindergarten in a comprehensive program aligned with the National Science Education Standards (NRC, 1996). They were able to demonstrate that K–2 students can successfully engage in science and engineering practices as defined in the new science framework (NRC, 2011) and that teachers supported with professional development and developmentally appropriate instructional materials can teach the crosscutting concepts and core ideas called for by the NRC framework. Equally important, CRDG has based its instructional programs on inquiry, providing students progressively more sophisticated experiences with the eight practices of science identified in the framework (NRC, 2011). We have demonstrated that all eight science practices can be effectively introduced at a developmentally appropriate level in grades K–2 by providing PD and supportive instructional materials.
Learning progressions have received increasing attention for their potential in supporting student construction of knowledge and development of skills. Developing a thorough understanding of scientific explanations of the world, students need sustained opportunities to work with and develop depth of understanding and connections over long periods of time (NRC, 2007). The NRC science framework embraces this conceptualization of learning progressions, as do we, in proposing the SEE project (NRC, 2011; Corcoran, et al., 2009).
Learning progressions have been defined as sequences of successively more complex ways of reasoning about a set of ideas (National Assessment Governing Board, 2008), in which learners move from novice to expert after extensive experience and practice, building on prior knowledge and developing increasingly more sophisticated explanations (Shavelson & Kurplus, 2011). Corcoran et al. (2009) define learning progressions as “empirically grounded and testable hypotheses about how students’ understanding of, and ability to use, core scientific concepts and explanations and related scientific practices grow and become more sophisticated over time, with appropriate instruction” (p. 8). The hypotheses are then tested empirically to assess how valid they are.
