Ambitious teaching is supported by four sets of core practices that work together throughout every unit of study. These practices start with designing units of instruction (Planning for engagement with important science ideas); they then focus on making visible what students currently know about the science being taught (Eliciting students’ ideas); they help the teacher guide sense-making talk around investigations and other kinds of lab activities or readings (Supporting on-going changes in thinking); and finally they help the teacher scaffold students’ efforts to put everything together near the end of a unit (Pressing for evidence-based explanations).
