Inquiry-based learning (also enquiry-based learning or inquiry learning) is a constructivist instructional strategy widely adopted in the 1970s¹⁾ and based on John Dewey's views on learning as active, learner-centered process which should be based on real-world examples instead of rote fact memorization. Inquiry represents questioning which fosters curiosity and questioning by students. During the inquiry-based learning discovery is guided by learners through forming questions and finding answers to those questions alone or in teams.

The idea of inquiry-based learning is to foster characteristics of good learners and encourage them in the educational process. These characteristics²⁾ include confidence in the ability to learn, enjoying problem-solving, trusting one's own judgement, not fearing being wrong, a flexible point of view, and respect for facts. These qualities, according to Postman and Weingartner³⁾ can be fostered through an approach in which the teacher:

• rarely tells the students what they need to know since that would reduce their excitement in finding things out on their own,
• interacts with students mostly through questioning and encourages interaction among students,
• does not accept short answers, but rather tries to deepen them by further questioning,
• rarely summarizes what students' discussion and what they have learned since learning is a continuous process.

The inquiry-based process of learning can be described as a cycle based on these activities mainly through following main steps:

• Questioning and curiosity provoked through questioning by the teacher together with taking the responsibility for their own learning by the students starts this process of learning.
• Investigation, gathering of information and studying materials, observing and other related activities are then expected to be performed by the students.
• This is followed by a synthesis of collected information, building hypotheses and possible explanations and planing on how to prove them.
• Development and presentation of explanations. New questions may arise at this point.
• Reflection on the original question, the research path, and the conclusions. Newly arisen questions form the beginning of a new cycle.

These steps in general are quite similar to the steps of problem-based learning. Differences between these two approaches are minimal according to some⁴⁾ and appear only in their origins (problem-based learning was developed in medical education and inquiry-based learning in science education), other suggest it is the role of the teacher:

• “In an inquiry-based approach the tutor is both a facilitator of learning (encouraging/expecting higher-order thinking) and a provider of information. In a PBL approach… the tutor does not provide information related to the problem — that is the responsibility of the learners.”.⁵⁾

Some authors suggest different inquiry-based learning modes depending on the level of scaffolding⁶⁾:

• structured inquiry - when teacher presents a problem and main frames for addressing it,
• guided inquiry - when teacher provides questions to motivate students, but the research they do is self-directed, and
• open inquiry - when students formulate questions and investigate them themselves.

Advantages of inquiry-based learning are increase in students motivation, active approach to learning, academic skills and intellectual habits⁷⁾. Students are also encouraged to develop of critical thinking, reflect on their learning, use different learning resources and gain deeper understanding of the course concepts.⁸⁾

An example of inquiry-based learning is learning about language using a Star-Trek episode as a motivator⁹⁾. In the Star Trek: The Next Generation episode “Darmok” viewers are introduced to the concept of Tamarian language spoken by an alien civilization. Weather this invented language could be an actual human language was debated by many professional linguists. A possible instructional plan for learning about language characteristics based on this episode is the following:

• Show students the “Darmok” episode
• Pose the problem to them: could Tamarian be a human language?
• Provide students with resource materials or encourage them to look them up themselves.
• Assist them if necessary on how to research the question and conduct analysis of language properties.
• Analysis of results and reflection.
