The Instructor's Shadow: Three Trainees, Three Learning Histories
At a government Industrial Training Institute in a small Punjab town, an instructor has 30 students in a six-month electrician course and eight weeks left before the final practical examination. He describes three students. Gurpreet completes a three-way switchboard correctly when working alone but repeats the same connection four or five times, checks the tester repeatedly, and makes wiring errors whenever the instructor stands beside his bench. Manpreet practised enthusiastically for the first month while each finished board earned a merit entry in a notebook; when the entries were stopped for shortage of time, his practice dropped to almost nothing, though he still completes tasks when the instructor assigns them. Ravi watched a senior student wire a distribution board once, then reproduced it without trial and error, but could not explain why a particular terminal was chosen. The instructor also notices that students practise on grey wiring boards while the examination uses black boards with differently colour-coded wires, and last year six of his students failed the practical.
1. Identify the learning process operating in each of the three trainees and state, with reasons, whose behaviour must change first if the practical pass rate is to improve.

Gurpreet - classically conditioned anxiety plus faulty stimulus control. His skill is intact when the instructor is absent, so this is not a competence deficit. The instructor's approach has repeatedly been paired with correction, deadlines and public criticism; it now functions as a conditioned stimulus producing a conditioned emotional response (shaking, heightened arousal). The four or five repeat checks are a safety behaviour: they briefly reduce anxiety and are therefore negatively reinforced, which is why the checking is increasing rather than dying out. The instructor's presence also acts as a discriminative stimulus signalling 'evaluation', so the same task is followed by different consequences in the two conditions.
Manpreet - operant conditioning on a continuous reinforcement schedule that was abruptly withdrawn. Merit entries worked as tokens backed by praise. Continuous reinforcement produces rapid responding and rapid extinction, which is exactly the observed pattern. The task did not become less attractive; the consequence disappeared.
Ravi - observational learning. Attention, retention and motor reproduction occurred after a single model without trial and error, but he could not verbalise the rule, so he copied the response rather than the principle and may not transfer it to a differently wired board.
Whose behaviour must change? The instructor's. Gurpreet's anxiety was built by the instructor's own conduct, so graded, non-evaluative presence and an end to public correction come first. The grey-versus-black board gap points the same way: last year's six failures suggest trainees learned to respond to grey boards rather than to wiring logic, which is a training-design fault, not a student fault.
2. Design an eight-week training plan that addresses all three problems and the board-colour mismatch. Justify each element with the principle behind it.

Weeks 1–2 - reduce the evaluation cue and train generalisation. The instructor stands at Gurpreet's bench while doing paperwork, says nothing evaluative, and withdraws for short intervals, lengthening them as checking behaviour falls. This is graded exposure with response prevention of the checking ritual. In parallel, all students practise on three board types (grey, black, and mixed wire colours), so that 'board' stops predicting a single correct answer - stimulus discrimination training by wiring logic rather than by surface appearance.
Weeks 3–4 - shift Manpreet to an intermittent schedule. Praise moves from every board to every third or fourth, then to a variable ratio, and merit points are exchanged for a valued outcome (a tool-kit session, responsibility for the display board) rather than for each unit of work. Intermittent schedules build slower acquisition but far greater resistance to extinction, so practice will survive the removal of tokens. Instructions and self-check sheets give the behaviour a discriminative cue independent of the instructor.
Weeks 5–6 - make Ravi's observational learning explicit. After watching a model, Ravi must verbalise the rule ('the live terminal goes to…') before reproducing it, and then apply it to a different board. Verbal coding is the retention process that turns copying into transferable learning.
Weeks 7–8 - assessment under examination-like conditions. Timed trials on black boards, unknown fault-finding, and the instructor walking the room continuously so that his presence stops predicting evaluation. Final trials are scored on a checklist, giving evidence rather than impression, and students see their own error patterns.
3. The instructor claims Manpreet is 'lazy and unmotivated'. Using evidence from the case, argue for or against this claim and say what evidence would settle the question.

The claim is not supported. Laziness would predict low effort across conditions; Manpreet's effort was high under one consequence and low under another, which is the signature of a motivational schedule effect rather than a stable trait. He still completes work when the instructor assigns it, showing that the behaviour is available. Two explanations remain open: the merit entry was the only reinforcer sustaining practice, or stopping the entries was experienced as a loss and produced frustration and withdrawal. These predict different remedies - a leaner intermittent schedule versus reinstating recognition in a new form.
Evidence that would settle it: (a) a brief experimental manipulation, reinstating entries for two weeks on a variable schedule and measuring time-on-task; (b) an interest inventory and a choice test (does he choose wiring tasks when free to choose?); (c) observation of whether he practises when working alongside a peer he admires. If practice rises when reinforcement returns, 'lazy' is a labelling error; if it stays flat across all conditions, look for skill gaps or avoidance. Labelling a trainee on the basis of one schedule change is exactly the error the case is built to expose.
