Final answer:
Option (B), Case studies and examples are revised to provide current and applicable information for students, acting as illustrative instances that showcase the importance of a topic through problem-solving strategies and identification of known and unknowns.
Step-by-step explanation:
Case studies and examples are crucial tools in educational settings as they provide relevant and useful information for students. The revision and replacement of case studies ensure that the information presented is both current and applicable to the students' learning. In practice, these case studies and examples serve as illustrative instances or pertinent examples that demonstrate the importance of a topic or concept. They often involve problem-solving strategies that include the identification of known and unknown factors within a given scenario.
For instance, in a problem-solving situation, students are encouraged to:
- Identify examples within the narrative that provide details about people, places, things, and events.
- Make a list of what is given or what can be inferred from the problem as stated (identify the knowns).
- Determine whether the situation involves a specific type or case of a problem, which can aid in deriving solutions.
By using these steps, students can tackle various problems by covering up one number and solving for it using the remaining information. This not only tests their understanding of the concept but also demonstrates problem-solving agility.
