What category of cognitive objectives does not require any physical action on the part of students?

The category of cognitive objectives involves mental processes such as understanding, analyzing, evaluating, and applying knowledge. These objectives focus on the intellectual skills that students need to develop, which do not necessitate any physical action or movement. In contrast, cognitive objectives center on thinking and processing information, making them crucial for goals related to comprehension and knowledge retention.

The affective category pertains to emotions and attitudes, which may involve personal engagement but do not require physical action either. However, it is more focused on feelings and values rather than cognitive processes. Psychomotor objectives specifically refer to skills that involve physical activity and motor skills, such as driving or performing a procedure, which requires coordination and physical execution. Technical objectives often encompass both cognitive and psychomotor skills in fields like engineering or computer science, necessitating practical application along with theoretical understanding.

Thus, cognitive objectives stand out as the category that is purely mental and does not involve any physical activity from students.
