Tóm tắt	The Team Situation Awareness Scale (TSAS) extends individual situational awareness measurement to the team level, assessing how well team members collectively perceive the task environment, understand shared information, and coordinate their actions. Developed by Endsley, Salas, and collaborators in the 1990s–2000s, the TSAS measures team-level SA, recognizing that in complex operations (emergency response, military command, operating rooms), task success depends not just on individual operator awareness but on shared mental models, communication, and coordinated decision-making.	The NASA Task Load Index (NASA-TLX) is a multidimensional subjective workload assessment tool developed by Sandra Hart and Lowell Staveland at NASA's Ames Research Center in 1988. It measures six dimensions of cognitive and physical task load to quantify operator workload across diverse task domains, from aviation and process control to human-computer interaction. The TLX has become the gold standard for workload measurement in human factors research and applied settings.
