Inquiry is an educational strategy that shifts focus on to the students. It basically means learning by involvement and engagement. It is student-centric, hence, the teacher guides the student towards their own research and means of problem-solving. It also allows them to make links to different topics and subject areas.
Some inquiry-based teaching strategies would include asking open-ended questions, instead of supplying information, to promote thinking and deeper understanding; investigating case studies to understand the practical applications or real-life scenarios; individual or group projects, group and class discussions on controversial topics, etc.
Inquiry-based teaching is definitely a great strategy to incorporate into the classroom, to allow for creativity, critical thinking, building interpersonal relationships, peer-peer learning, and problem solving among others.
