Explanation:

"Problem-based learning" is a teaching approach that centers on students. It allows the student to learn on their own or to solve problems on their own. This is also based on their own "reasoning" and "reflection." So, the role of the teacher here is to facilitate or guide the students. He doesn't need to provide direct instruction to the student. The goal here is "self-identified," so this means that the students identity their own goals. Real word problems are used in order for the students to learn how to solve them on their own.
