Our approach to instruction centers on the value of deeper learning. In math, for example, our students spend most of their time struggling through problems, constructing various solutions, evaluating the strengths and drawbacks of different methods, and discussing their thinking with the class. In science, students are doing scientific work, from designing experiments, developing reliable methods to answer questions, and gathering evidence to analyzing data and building models that help explain phenomena. In history, our students must discern which sources are valid and which are biased, then make sense of conflicting accounts of events – and understand why they matter. In all disciplines students grapple with demanding text, cite evidence, and build arguments that hold up to scrutiny.
