Which training method involves both the trainer and trainees actively participating in the learning experience?

The correct choice is interactive lectures because this training method emphasizes the involvement of both the trainer and trainees throughout the learning process. Interactive lectures incorporate techniques such as discussions, group activities, and question-and-answer sessions that engage participants, allowing them to contribute and apply the material actively. This collaborative approach fosters a more dynamic learning environment where trainees can better absorb and retain information through participation and engagement with both the subject matter and their peers.

In contrast, self-paced learning typically allows trainees to progress through the material individually, without active engagement from a trainer. Traditional lectures mainly consist of the instructor delivering content while students listen, limiting their participation. Online courses can vary, but many lack the immediate interaction characteristic of interactive lectures, leading to a more passive learning experience when they are not designed to facilitate real-time engagement.
