Under what circumstances are classroom instruction and computer-based training equally effective?

A) when the trainees are all close in age
B) when the trainees are all equally educated
C) when the trainees are taught with the same instructional methods
D) when the trainees are trained with experienced trainers

When the trainees are taught with the same instructional methods, classroom instruction and computer-based training can be equally effective. This means that the content, structure, and delivery of the training materials are consistent between the two methods. This ensures that all trainees receive the same information and that the learning experiences are similar, regardless of the delivery method. It is important to note, however, that some trainees may still prefer one method over the other, and that individual learning styles and preferences should also be taken into account when deciding on a training approach.
