Which instructional method involves the instructor performing a task while explaining it?

The instructional method where the instructor performs a task while explaining it is known as demonstration. This approach allows the instructor to visually show students how to complete a task or process in real time, providing a clear model for learners to follow. As the instructor demonstrates, they can articulate each step, highlighting key points, techniques, or considerations that are essential to understanding the task. This method is particularly effective in technical subjects or hands-on training because it engages visual and auditory learning styles, making it easier for students to grasp complex concepts or procedures.

In contrast, a lecture typically involves a one-sided presentation where information is conveyed without hands-on demonstration. Group discussions focus on student participation and ideas sharing rather than direct instruction from an instructor. Collaborative learning, while interactive, revolves around students working together to solve problems rather than the instructor demonstrating a skill or task. Thus, demonstration stands out as the method where the instructor actively models a task while providing explanations.
