Final answer:
The claim that a speaker should stay behind the podium while presenting a PowerPoint is false; speakers should use movement and posture tactically to engage the audience and enhance their presentation.
Step-by-step explanation:
The statement 'A speaker should stay behind the computer or podium while their PowerPoint is being shown' is false. While using a PowerPoint or other presentation software, the speaker should maintain a relaxed and natural posture, avoid stiffness or slumping, and incorporate purposeful movement to engage with the audience. Physical delivery considerations, such as posture and movement, are important aspects of a successful presentation. A static position behind a computer or podium could hinder the connection with the audience and make the delivery less dynamic. Therefore, speakers should balance movement with the delivery of their speech and use their presence to emphasize key points or transitions, making the presentation more effective and engaging.
