Enquiry based learning

1. Confirmation inquiry:
   The learner is asked a question, as well as a method whose final result is already known. The goal is to validate the results. It allows learners to strengthen already established ideas and practice their research skills.
   
2. Structured inquiry:
   The question and method of achieving the result is given to learners, but the aim is to provide an explanation which is already based on the evidence collected during the research process.
   
3. Guided inquiry:
   Only questions are given to learners. The main objective is to plan the research method and test the issue itself. This type of investigation is usually not structured as in the previously mentioned form.
   
4. Open inquiry:
   Learners need to develop their own questions, develop investigative methods, then make the same research. At the end of the process, they have to submit their results.
   

Enquiry based learning describes an environment in which learning is driven by the student's research process. Starting with a planning and under the guidance of mentor, students identify their problems and issues. They then examine the resources available to explore the topic, thus acquiring the necessary knowledge. The knowledge thus acquired is easier to maintain, as it was a gained experience and a real problem.
