This case study focuses on how a high school student, Laura, learned the meaning of the velocity sign. By moving a toy car she created many real-time graphs on a computer screen. The study strives to show that her learning was not just an acknowledgment of a rule, but a broad questioning and revision of her thinking about graphs and motion. Laura’s process exemplifies what is involved in the learning of a way of symbolizing situations of physical change.
