Teachers constantly struggle to get students actively engaged and invested in their own learning. It can be even more difficult to engage those students in critical thinking and 21st century skills. Problem-based learning (PBL) provides a student-led format with real-life learning experiences, offering a purpose for instruction. By relinquishing control and allowing students to become more involved in their own learning, the teacher is able to become more of a facilitator or guide. Students learn to communicate effectively, take responsibility, and set goals with problem-based learning. If all components of PBL cannot be implemented in the classroom due to time or other factors, choice can still be implemented. Research shows that student choice is one of the largest contributors to student engagement. Because of this, students who are given choice and authentic learning opportunities are more likely to recognize the value and purpose of learning.
