Should limits or derivatives be taught first in calculus?
We want students to grasp calculus as a coherent framework, not a bag of tricks. Does introducing derivatives via limits from the outset solidify the "why," or does it risk losing students in abstraction before they see the utility? Is there a proven effective compromise?

Having taught both sequences, I've seen the trade-offs firsthand. I would recommend a hybrid "spiral" approach. Start with the derivative intuitively, using velocity and slope as tangible motivators. Let students calculate derivatives using simple limits numerically to see the process. Once they are convinced of the derivative's power and utility, then formalize the concept with the precise (ε-δ) definition of the limit. This method respects the cognitive load. Starting with pure abstraction often breeds confusion, while delaying the formal foundation can leave advanced students unprepared. The key is to connect the intuition to the rigor explicitly.
