Final answer:
The learning effect is exemplified by latent learning and the use of worked examples to efficiently solve multiple-part problems.
Step-by-step explanation:
The learning effect is illustrated by the phenomenon of latent learning, which occurs when knowledge is acquired without any immediate application or reinforcement but is revealed later when needed. For example, Ravi learns the route to school by observing his dad but only demonstrates this knowledge when he has to bike to school himself, showcasing latent learning.
Worked examples are another instance of the learning effect in practice. These examples include multiple-part problems and employ problem-solving strategies, enabling students to assimilate the method of solving complex problems and remember the techniques more efficiently through repeated exposure.
