概要	The think-aloud protocol is a method for making cognition visible by having people verbalize their thoughts while performing a task. In education it is the primary tool for studying response processes — how students actually read, reason about, and answer test items and learning tasks. Grounded in Ericsson and Simon's theory of verbal reports as data, it provides the response-process evidence that modern validity frameworks require, revealing whether items measure the intended thinking, and exposing strategies, misconceptions, and construct-irrelevant difficulties.	The Think-Aloud Protocol is a usability testing method in which participants verbalize their thoughts while completing tasks on a system. As users navigate an interface, they continuously narrate their observations, interpretations, and reasoning, allowing researchers to understand their mental models, decision-making, and frustration points. Originating from cognitive psychology research by Ericsson and Simon (1980), this method was adapted for HCI by Clayton Lewis and has become one of the most widely used techniques for identifying usability problems and understanding user behavior.
