A storyline is…
A storyline is a coherent sequence of lessons, in which each step is driven by students’ questions that arise from their interactions with phenomena.
For example, take an albino child borne from dark-skinned parents. Students should have a lot of questions that delve into various topics like genetics, environment, DNA, etc.
A student’s goal is to be able to explain a phenomenon or solve a problem. Students work together to create questions, to answer them, to model them, and to understand them. A storyline provides a coherent path toward building disciplinary core idea and crosscutting concepts, piece by piece, anchored in their own questions.
