In this video, I break down Merrill’s First Principles of Instruction in a way that’s actually usable for lesson planning—whether you’re teaching online, hybrid, or in a physical classroom. The core idea is simple: great instruction is problem- or task-centered, and everything else supports learners as they move from “I’ve seen it” to “I can do it” to “I can use it in real life.” I walk through what Merrill’s model is, why it shows up so often in instructional design, and how you can apply it without turning your teaching into a rigid template. I focus on the five principles: Task/Problem-Centered learning, Activation (connecting to prior knowledge), Demonstration (showing what good performance looks like), Application (practice with feedback), and Integration (bringing it back to the learner’s context so it sticks). My main takeaway: if you start by designing the real-world task first, the rest of your lesson becomes easier to structure—and your students get a clearer sense of “why we’re doing this.” Use Merrill’s principles as a checklist to tighten your lesson flow and make learning more transferable, not as a theory you memorize.
