Students learn more when they ask their own questions and look for answers. Inquiry-based learning, or IBL, is a method that puts that process at the center of instruction. Southern Illinois University Edwardsville’s (SIUE) online Master of Science in Education (MSEd) in Curriculum and Instruction (C&I) with Emphasis in Advanced Teaching Strategies prepares teachers to use IBL in their own classrooms.
This guide breaks down what inquiry-based learning looks like in practice, the different forms it can take and how teachers can start using it. Along the way, it walks through real classroom examples across several subjects, from science labs to English discussions.
What Is Inquiry-Based Learning?
Inquiry-based learning starts with a question rather than an answer. According to XQ Institute, it isn’t just for science class. Students explore, investigate and build understanding through their own inquiry. The teacher guides the process; they do not drive it.
John Dewey laid the groundwork in the early 1900s. He argued that real learning comes from experience and reflection, not from passive receipt of information. IBL builds directly on that idea.
The approach works across subjects and grade levels. Science classes use it for experiments. History classes use it to analyze primary sources. Math classes use it to work through open problems.
Language arts classes use it to weigh competing readings of the same text. The structure adjusts by subject, but the core stays the same: students lead their own discovery.
What Are the Types of Inquiry-Based Learning?
IBL takes several forms, according to the New York State Education Department. Four types appear most often in K-12 settings: structured, guided, open and controlled. Here is how each type typically plays out in the classroom.
- Structured inquiry: Gives students a question and a defined procedure. They follow the steps to find an answer, though the outcome itself stays open since the method is set by the teacher. This form works well when students are new to inquiry and need more guidance to stay on track.
- Guided inquiry: Gives students a question but no set method. Students choose how to investigate. The teacher provides support without directing each step. Students build independence and critical thinking over time.
- Open inquiry: Gives students full ownership. They form the question, design the investigation and analyze the results. This is the most complex form. It works best with experienced students who are ready to manage their own process.
- Controlled inquiry: Sits between guided and open inquiry. The teacher generates several possible questions and curates the resources students can use to investigate them, and students choose which question to pursue from that shortlist. This form works well for classes that need more structure than open inquiry allows, but more choice than guided inquiry offers.
The best choice depends on the grade and the subject, along with how ready students are to work with less structure. Refining that judgment call is exactly what SIUE’s online MSEd, C&I – Advanced Teaching Strategies program helps teachers do.
What Are Examples of IBL in the Classroom?
These types look different once they move from theory into an actual lesson. The examples below show how the same question-first approach plays out across four common subject areas.
- Science: A middle school class asks why plants in one area of the school grow better than others. Students form a hypothesis, design a test, collect data and present findings.
- History: A high school class reads primary sources from two sides of the same conflict. Students form their own reading before opening a textbook.
- Math: An elementary class gets a set of objects and one task: find every way to sort them. Students share and defend their groupings.
- English: Students read two accounts of the same event. They ask which one they trust and why. They build criteria and apply them to the texts.
In each case, the question drives the lesson. Students build content knowledge and thinking skills through searching for an answer.
What Are the Benefits of IBL?
IBL builds skills that go beyond any single subject. Students who practice inquiry learn to ask better questions. They read sources with more care and defend ideas with evidence. These skills transfer across classes and carry into life beyond school.
Research cited by XQ Institute links stronger student engagement to concrete outcomes, including higher rates of high school completion and better performance on standardized tests. When students help shape the inquiry, they invest more in finding the answer. Engaged students are also more emotionally and intellectually invested in their own learning.
IBL also supports a range of learners. Students who struggle with direct instruction often thrive when they have more control over how they learn. The open structure gives more students a way in. For a closer look at teaching to varied student needs, see SIUE’s guide to differentiated instruction.
How Do You Use IBL in the Classroom?
Teachers new to IBL often start with structured inquiry. As students gain confidence, they can shift to guided and then open inquiry.
Start with a strong question. A good IBL question has more than one answer. It pushes students to investigate rather than recall.
Build in time to explore. IBL takes more time than direct instruction. Plan lessons that let students return to a question and revise their thinking.
Teach inquiry skills directly. Students need to learn how to ask useful questions, find credible sources and draw fair conclusions. These skills need practice.
Debrief after each inquiry. Ask students what they found and how they found it. The reflection step turns a search into lasting learning.
Apply IBL in Your Classroom
IBL works best when it is part of the classroom routine, not a one-time event. Small, regular moments of inquiry, like a single open-ended question inside an otherwise traditional lesson, add up faster than one large project attempted once a semester. Teachers who build in that habit see the payoff in how students approach problems long after the specific lesson ends.
Teachers who understand IBL can build lessons that develop thinking skills across subjects. SIUE’s online MSEd, C&I – Advanced Teaching Strategies builds that same foundation through courses like Analysis of Instruction and Differentiated Instruction, giving working teachers the tools to design inquiry-driven lessons of their own. The program is completed fully online, which fits the schedule of teachers who are also working full time.

Frequently Asked Questions
Inquiry-based learning raises a few common questions for teachers who are new to the approach. Here are quick answers to the ones that come up most often.
What is an example of inquiry-based learning?
A middle school science class investigating why plants grow differently across the schoolyard, then forming a hypothesis, testing it and presenting findings, is a common example of inquiry-based learning in action.
What are the four types of inquiry-based learning?
The four most common types are structured, guided, open and controlled inquiry, which range from teacher-directed to fully student-led.
Is inquiry-based learning only used in science classes?
No; teachers use IBL in history, math and English classes as well, adapting the structure to fit the subject.
How is inquiry-based learning different from traditional teaching?
Traditional teaching starts with an answer and works backward to explain it, while IBL starts with a question and lets students build toward an answer.
Do teachers need special training to use inquiry-based learning?
Formal training helps, but teachers can start small by turning one lesson into a structured inquiry activity before expanding from there.
