Inquiry-based learning is an educational strategy in which students actively participate and perform self-directed investigations on a topic or a problem defined previously. In this process, the students follow and apply recognisable methods and practices, formulate a hypothesis, and ask questions, with the ultimate goal to solve the inquiry defined at the beginning of this strategy. In the investigation phase, the students prove the hypothesis or repeat the process involving the elements learned in the tries that failed. This goes on until the students prove the hypothesis, answer the questions, and explain the problem they are investigating.
