Final answer:
Incidental learning or situational learning refers to the strategy of teaching a concept during an event in which it occurs, helping students apply the concept in real-world contexts.
Step-by-step explanation:
The strategy of teaching a skill or concept during an event or situation in which is it presently occurring can be called incidental learning, just-in-time teaching, or more generally, situational learning. This approach allows students to apply the concept in a real-world context, enhancing comprehension and retention. It contrasts with more formal education methods and emphasizes the importance of learning through experience. Examples of this might include teaching a child about monetary value by having them make purchases during shopping or introducing a student to the principles of physics through hands-on experimentation during a sporting event.
