Learn how cost models are developed Learn the principles of systems engineering sizing Compare COSYSMO to other modelsĦ What is COSYSMO? Short answer: a Model But it depends who is asking Woolfolk, "Chapter 7 Cognitive views of learning," in Educational Psychology, 7th ed. Conditional knowledge - “knowing when and why” to apply the declarative and procedural knowledge. Performing the process demonstrates procedural knowledge. Describing a process is declarative knowledge. Procedural knowledge - “knowing how” to do something and must be demonstrated. It is “knowing that” something is the case.
