What is also referred to as an Appearance Model used for instructional or experimental purposes?

An Appearance Model, often used for instructional or experimental purposes, is best represented by a mock-up. A mock-up is a full-size or scale model that is created to demonstrate the design’s physical attributes, ensuring that the aesthetics and overall look of a product are communicated effectively. It doesn’t need to function like a prototype; instead, it primarily serves to convey how the final product will appear and allows stakeholders to visualize and assess design elements without delving into the functional aspects.

Mock-ups are particularly useful in the early stages of design when feedback on visual appeal and design elements is crucial. They can also be employed in presentations to help others understand the concept without needing to concern themselves with the technical details or functionality of the product. This makes them a vital tool in the design process.
