Inquiry-Based Learning Characteristics

Specific learning processes that people engage in during inquiry-learning include:

Creating questions of their own
Obtaining supporting evidence to answer the question(s)
Explaining the evidence collected
Connecting the explanation to the knowledge obtained from the investigative process
Creating an argument and justification for the explanation

Inquiry learning involves developing questions, making observations, doing research to find out what information is already recorded, developing methods for experiments, developing instruments for data collection, collecting, analyzing, and interpreting data, outlining possible explanations and creating predictions for future study.

Levels
There are many different explanations for inquiry teaching and learning and the various levels of inquiry that can exist within those contexts. The article titled The Many Levels of Inquiry by Heather Banchi and Randy Bell (2008) clearly outlines four levels of inquiry.

Level 1: Confirmation Inquiry
The teacher has taught a particular science theme or topic. The teacher then develops questions and a procedure that guides students through an activity where the results are already known. This method is great to reinforce concepts taught and to introduce students into learning to follow procedures, collect and record data correctly and to confirm and deepen understandings.

Level 2: Structured Inquiry
The teacher provides the initial question and an outline of the procedure. Students are to formulate explanations of their findings through evaluating and analyzing the data that they collect.

Level 3: Guided Inquiry
The teacher provides only the research question for the students. The students are responsible for designing and following their own procedures to test that question and then communicate their results and findings.

Level 4: Open/True Inquiry
Students formulate their own research question(s), design and follow through with a developed procedure, and communicate their findings and results. This type of inquiry is often seen in science fair contexts where students drive their own investigative questions.

Banchi and Bell (2008) explain that teachers should begin their inquiry instruction at the lower levels and work their way to open inquiry in order to effectively develop students' inquiry skills. Open inquiry activities are only successful if students are motivated by intrinsic interests and if they are equipped with the skills to conduct their own research study.

Open/true inquiry learning
An important aspect of inquiry-based learning is the use of open learning, as evidence suggests that only utilizing lower level inquiry is not enough to develop critical and scientific thinking to the full potential. Open learning has no prescribed target or result that people have to achieve. There is an emphasis on the individual manipulating information and creating meaning from a set of given materials or circumstances. In many conventional and structured learning environments, people are told what the outcome is expected to be, and then they are simply expected to 'confirm' or show evidence that this is the case.

Open learning has many benefits. It means students do not simply perform experiments in a routine like fashion, but actually think about the results they collect and what they mean. With traditional non-open lessons there is a tendency for students to say that the experiment 'went wrong' when they collect results contrary to what they are told to expect. In open learning there are no wrong results, and students have to evaluate the strengths and weaknesses of the results they collect themselves and decide their value.

Open learning has been developed by a number of science educators including the American John Dewey and the German Martin Wagenschein. Wagenschein's ideas particularly complement both open learning and inquiry-based learning in teaching work. He emphasized that students should not be taught bald facts, but should understand and explain what they are learning. His most famous example of this was when he asked physics students to tell him what the speed of a falling object was. Nearly all students would produce an equation, but no students could explain what this equation meant. Wagenschien used this example to show the importance of understanding over knowledge.

Inquisitive learning
Sociologist of education Phillip Brown defined inquisitive learning as learning that is intrinsically motivated (e.g. by curiosity and interest in knowledge for its own sake), as opposed to acquisitive learning that is extrinsically motivated (e.g. by acquiring high scores on examinations to earn credentials). However, occasionally the term inquisitive learning is simply used as a synonym for inquiry-based learning.
