Final answer:
The question asks which example best illustrates intrinsic motivation. Intrinsic motivation stems from internal satisfaction and personal reward, rather than external incentives.
Step-by-step explanation:
The question concerns which example best illustrates intrinsic motivation. Intrinsic motivation refers to engaging in behavior because it is personally rewarding.
Specifically, this pertains to doing an activity for its inherent satisfactions rather than for some separable consequence.
When individuals are intrinsically motivated, they act for the fun or challenge entailed rather than because of external products, pressures, or rewards.
The options given present various motivations for different actions; however, the example that most strongly illustrates intrinsic motivation is not clearly provided among them.
Nevertheless, based on the information, a scenario that would fit the definition of intrinsic motivation could be similar to option (b), where a businessman believes hard work is its own reward. This indicates an internal satisfaction with the effort put in, regardless of external praise or promotion.
Instructional strategies to enhance intrinsic motivation involve providing a sense of autonomy, competence, and relatedness.
For instance, when teaching materials offer a healthy challenge and foster a feeling of personal growth, students tend to be more intrinsically motivated.
Furthermore, it's crucial to consider the potential effects of extrinsic rewards on intrinsic motivation, as they can either increase it, in the case of unexpected rewards or verbal reinforcement, or diminish it if the reward becomes the exclusive focus of the activity.
