What are the least expensive and most readily available instructional techniques in training?

Lectures and explanations are often considered the least expensive and most readily available instructional techniques in training because they primarily require an instructor, a space for delivery, and basic materials such as slides or handouts. This method is highly cost-effective since it can accommodate a large number of participants without the need for extensive equipment or resources. This format allows instructors to convey a significant amount of information in a relatively short period, making it efficient for introducing concepts, theories, or procedures to trainees.

While hands-on simulations, group discussions, and interactive workshops can be highly effective, they typically require more resources, planning, and sometimes specialized equipment or environments. For instance, hands-on simulations necessitate specific tools or facilities to recreate scenarios, and interactive workshops often involve more complex logistics to facilitate participant engagement and collaboration. Group discussions, while less resource-intensive than some options, still require facilitation and may not be structured enough to effectively communicate the breadth of information that is efficiently delivered through lectures. Thus, lectures and explanations stand out as the most straightforward and accessible method for training.
