Inquiry-based teaching is a pedagogical approach that centers the curriculum around students' questions. It invites students to explore academic content by posing, investigating, and answering questions. This approach develops skills like research, problem-solving, and teamwork. It also fosters habits of lifelong learning by giving students ownership over their learning. However, some disadvantages are that it may lead to poorer performance on standardized tests, student embarrassment if they don't know answers, and potential teacher unpreparedness for this approach.
