An instructional approach that engages students in solving real-world problems individually or in groups is called:

The correct answer is Problem-based learning. Problem-based learning (PBL) is an instructional approach specifically designed to engage students in solving real-world problems, either individually or collaboratively in groups. In PBL, students are presented with complex, open-ended problems that mirror authentic challenges, and they work to identify what they need to learn to solve them. This method fosters critical thinking, problem-solving skills, self-directed learning, and collaboration, making the learning process highly active and relevant to practical applications.

• Lab-oriented method (B) typically refers to hands-on activities, especially in science, focusing on experiments and practical work. While it involves problem-solving, it is a more specific type of practical approach and not as broad as problem-based learning which can apply across many disciplines and does not always require a physical lab.
• Interactive approach (C) is a very general term that describes any teaching method involving active participation and exchange between students, or between students and teachers. While problem-based learning is interactive, not all interactive approaches are problem-based learning.
• None of these (D) is incorrect because problem-based learning precisely describes the instructional approach mentioned.
