Inquiry-based learning (IBL) is a student-centred learning methodology that invites students to follow the steps of the scientific method. It can be used to encourage students to investigate real-world problems. Students are invited to create their hypotheses, design experiments, collect data to support their ideas, analyse results, make conclusions and discuss ideas with their colleagues. Inquiry-based learning can be presented to students in a very structured format, can be built with a more open approach where students are guided by their teachers but have ownership of the chosen path, or it can be completely open, giving the students the freedom to explore the topic following their path.
