Step 1: Recall the source experiment.
Thorndike's puzzle-box cats slowly reduced their escape time by repeating whichever action worked, and this pattern is the basis of the theory.
Step 2: Turn the pattern into a classroom method.
A teacher gives a task without full instructions first, lets students try several approaches, and only guides them toward the correct one after they have made genuine attempts.
Step 3: Add reinforcement.
Correct attempts are praised or rewarded (matching the Law of Effect) and then practised repeatedly (matching the Law of Exercise), so the right response becomes automatic over time.
Final Answer:
Education applies trial and error by encouraging self-attempt, accepting mistakes, and reinforcing successful responses through repetition and reward.
