Antiquity: On-The-Job Training
On-the-job training, sometimes called direct instruction (or sit-by-me training in England; King, 1964, p. xvii), is the earliest kind of training. On-the-job training (OJT) is a face-to-face, one-on-one kind of training at the job site, where someone who knows how to do a task shows another how to do it. In antiquity, the kind of work that people did was mainly unskilled or semiskilled work not requiring specialized knowledge. Parents or other members of the group usually knew how to do all the jobs necessary for survival, and could pass their knowledge on to the children through direct instruction.
