Inquiry-based learning: what is it and main approaches

Inquiry-based learning is an active, student-centered approach that fosters 21st-century skills in elementary and secondary school classrooms in the United States.

Compared to traditional teaching, which focuses on the transmission of content, inquiry-based learning places the student at the center of the process. To this end, it promotes active learning, in which students learn by asking questions, researching reliable sources, analyzing data, and constructing their own explanations.

Below, we present a guide to inquiry-based learning as a key pedagogical approach in U.S. education. All of this information will help you understand the definition of inquiry-based learning, its different types, its main approaches, and why it’s important to implement it in the classroom.

What is inquiry-based learning?

Inquiry-based learning (IBL) is a student-centered, constructivist pedagogical approach in which students, guided by the teacher, formulate questions, investigate the answers, and reach their own conclusions, thereby actively constructing their own knowledge.

This methodology transforms students into researchers and places the question at the starting point of learning. In this context, the teacher collaboratively develops relevant questions with the class, provides access to reliable sources, guides the analysis of information, and helps each student defend their conclusions.

Several fundamental pillars underpin this basic framework and structure the entire approach:

• Inquiry cycle: an orderly process of asking questions, investigating, analyzing, explaining, and reflecting that guides all learning step by step.
• Questioning strategies: these are strategies rooted in the Socratic tradition of teaching through questions, designed to stimulate critical thinking.
• Essential questions: these are deep, open-ended questions that connect specific content to broader ideas and concepts.
• Research skills and information literacy: this refers to the set of skills needed to locate, evaluate, and use high-quality information sources independently and critically.
• Evidence-based reasoning: it is essential that students be able to defend each conclusion and argument with data, texts, and concrete evidence that anyone can verify.

Inquiry-based learning vs. other student-centered approaches

The roots of inquiry-based learning lie in constructivism, an educational movement that posits that each person constructs knowledge based on their own experience and reflection.

This idea originated with John Dewey in the early 20th century, a theorist who advocated for experiential learning, and was further developed by Jean Piaget, Lev Vygotsky, and Jerome Bruner. The discovery learning developed by Bruner is the approach most closely aligned with inquiry-based learning; it also draws on students’ curiosity to encourage them to investigate, experiment, and construct knowledge on their own rather than receiving it in a ready-made form.

Focusing specifically on inquiry-based learning, it is a form of student-centered learning and active learning. In the U.S. context, it is directly associated with 21st-century skills such as critical thinking, problem-solving, collaboration, and communication. Educational frameworks consider all these competencies to be essential for success outside the classroom.

Alongside this approach, others coexist, such as project-based learning, problem-based learning, design-based learning, and experiential learning. All of these approaches start with authentic questions or challenges, require research and analysis, and result in a product or solution connected to the real world, although each takes a different approach:

• Project-based learning: revolves around an extensive project with a public product as the final outcome to reinforce its relevance.

• Problem-based learning: begins with an open-ended and complex problem that allows for several practical solutions.
• Design-based learning: focuses on identifying needs, devising, and prototyping solutions in a practical way.
• Experiential learning: emphasizes direct action, reflecting on the experience, and applying what has been learned in real-world contexts.

Although IBL may incorporate projects, problems, or design processes, at its core lies the very act of inquiry, which must consist of asking the right questions, investigating rigorously, and arguing with sound reasoning. As you can see, this methodology shares many characteristics with good investigative journalism.

Theoretical foundations and research support

Beyond its origins, inquiry-based learning has operational frameworks that help implement it in the classroom, as well as research support that underpins its pedagogical value.

In the table below, we’ve compiled some examples of the frameworks and tools that help structure this approach in the classroom:

Why is inquiry-based learning important for students, teachers, and schools?

The importance of inquiry-based learning lies in the fact that it fosters strategic skills such as critical thinking, problem-solving, engagement, and adaptability. These power skills help students gain a deeper understanding of the subject matter.

Inquiry-based learning in the technological age

In the changing, dynamic, and complex environments of the technological age in which we live, this approach provides crucial value for developing the skills students need to learn, work, and actively participate in society.

The role of inquiry-based learning for students

When students work with authentic questions, conduct research, analyze data, and construct their own explanations, they systematically practice critical thinking and problem-solving. This leads to another benefit: they become more engaged in their learning and grow accustomed to participating in discussions, defending their ideas with evidence, and adapting when new information and different perspectives arise.

These skills are considered “power skills” in the job market, as we’ve mentioned, because they are transferable to any profession and are also useful for making informed decisions in their daily lives.

The contribution of inquiry-based Learning to schools and educational projects

For schools and institutions, inquiry-based learning also plays a significant role in better aligning the curriculum with students’ real-world experiences and the expectations of the education system.

By promoting active participation, curiosity, and reflection, this approach improves school culture, reduces disengagement, and supports key objectives such as college readiness, workforce readiness, and civic development.

An expected outcome of all these improvements is an increased likelihood that students will develop lasting learning that translates into better academic outcomes and enhances their capacity for lifelong learning.

What are the 4 types and main approaches of inquiry-based learning?

The 4 types of inquiry-based learning are categorized based on the level of student autonomy relative to the guidance provided by the teacher, ranging from the most to the least guided:

1. Confirmation inquiry: the student knows the question and the expected outcome in advance. Their task is to investigate to verify a known principle and practice the procedure.
2. Structured inquiry: the teacher provides the question and explains the method, but the conclusion remains open-ended. Thus, the student follows a set path without knowing exactly where they are supposed to end up.
3. Guided inquiry: in this case, the teacher only provides the question, and it is the student who chooses how to approach it and what answer to arrive at.
4. Open inquiry: finally, this represents the highest degree of autonomy, where students themselves formulate the question, choose the method, and draw their own conclusions. It is the type of inquiry-based learning that most closely resembles actual scientific research.

These approaches are often combined with methods such as project-based learning or problem-based learning, among others.

How to use inquiry-based learning in the classroom: a practical guide for U.S. teachers

To implement inquiry-based learning in the classroom, the teacher’s role is central, so they must be properly trained to achieve the best results. Teachers design lessons around fundamental questions, guide students’ research, foster collaboration, and evaluate both the research process and the final outcomes.

What are the 5 steps of inquiry-based learning?

Inquiry-based learning is structured around 5 fundamental steps: posing an interesting question, planning the investigation, gathering and analyzing information, developing explanations or products, and reflecting on the learning process.

It is important to understand that this is not a rigid structure; rather, the process can move forward and backward as new information emerges or if the initial question proves insufficient or needs to be reformulated:

• Step 1: the question. For this first step to serve as the driving force behind the investigation, the question must be interesting, open-ended, and challenging. Furthermore, it must be connected to the student’s reality. The goal is for it to spark genuine and in-depth inquiry.
• Step 2: planning. The student establishes a roadmap by deciding what they need to find out, where they can find that information, and what method they will use. They develop skills such as autonomy, organization, and the ability to design a research strategy.
• Step 3: data collection and analysis. In this phase, the student applies research skills and information literacy. They analyze the reliability of sources, compare approaches, and—very importantly—distinguish between what is relevant and what is incidental.
• Step 4: developing explanations or products. In this phase, they take action and draw conclusions or create products. The response must be well-reasoned and evidence-based. They may produce a report, presentation, multimedia project, or prototype.
• Step 5: reflection. The final step helps consolidate learning through a metacognitive process in which the student analyzes which strategies have worked best, what obstacles they encountered, and what they will do differently next time to improve the process.

In this sequential structure, the teacher’s role begins with more intensive guidance and gradually shifts toward fostering student autonomy as the student refines their technique. In this way, students learn to self-regulate.

Example of inquiry-based learning in U.S. classrooms

A simple example of inquiry-based learning involves posing a real-life question to students, guiding them to seek answers, and asking them to present their conclusions through a project or presentation. To help you see how this works step by step, we’ll walk you through a specific example: a science class.

• Asking the question: why have fish populations in the city’s river declined this year, and how does community activity influence this? As you can see, this is an essential question because it cannot be answered with a simple yes or no; the issue is connected to the students’ local environment and opens up many avenues for investigation.
• Planning: students will choose which elements to measure in the water (microplastics, nitrates, etc.), where to collect samples, and which public data to consult.
• Collect and analyze: field trips to collect samples, laboratory analysis, an interview with a local biologist, cross-checking data, etc.
• Develop the final product: based on the data collected, the student group creates a map of the river basin that identifies the most polluted areas and develops a proposal for improvement that they can present to the School Board and their city council.
• Reflect: the inquiry-based learning cycle concludes when students assess whether the samples were sufficient, what biases or obstacles they encountered, and what new questions have arisen as a result of their investigation.

Research does not proceed in a straight line but is adjusted as evidence is gathered.

Key benefits of inquiry-based learning for students, teachers, and schools

Among the key benefits of inquiry-based learning are the development of skills such as critical thinking free from confirmation bias and more robust problem-solving. Additionally, it encourages student engagement in activities and fosters meaningful and transferable learning for elementary and secondary classrooms (K-12).

To summarize what we’ve covered throughout this guide, we’ve grouped the benefits according to who they benefit.

Benefits of inquiry-based learning for students

Students who participate in this methodology gain the following benefits:

• Development of critical thinking and problem-solving skills. Students must reason, seek new approaches, verify information, and defend their conclusions with evidence.
• Consolidation of deep and transferable learning. People who learn through inquiry activate their existing knowledge, restructure information, and better assimilate new data. We can say that they learn to optimize their learning and can apply what they’ve learned to other subjects or areas of their lives.
• Strengthening of autonomy and responsibility for their own learning. Students create their own work plans as independent thinkers.
• Fostering curiosity and intrinsic motivation. When students formulate their own questions, their motivation increases, creating effective opportunities to acquire new knowledge.

Benefits of inquiry-based learning for teachers

Teachers will also benefit from this constructivist methodology:

• It accommodates diversity. This approach adapts the learning experience to each student’s pace and style, whether they work alone or in small groups, without the need to create a specific learning path for each individual.
• It adapts to any subject and grade level. Asking questions, investigating, and drawing conclusions is a sequence that can be adapted to math, writing, the study of historical events, and more.
• It provides a progressive framework. Teachers can begin the course with a highly structured inquiry and gradually grant the class more autonomy.

Benefits of inquiry-based learning for schools and school districts

The benefits of inquiry-based learning extend beyond the classroom. When this approach is adopted consistently, its effects are felt throughout schools and school districts.

Within this ecosystem, two strategic benefits stand out:

• It helps cultivate competencies that educational frameworks consider essential.
• It connects the school to its surrounding community.

There is something you should keep in mind: all these benefits will depend on the students’ prior knowledge base as well as the skill of the teacher guiding them and their ability to turn challenges into opportunities for improvement.

Common challenges in inquiry-based learning and how to overcome them

While it is true that inquiry-based learning offers significant advantages for improving educational quality, it also presents challenges such as time constraints, classroom management, curriculum adaptation, and assessment.

However, tools already exist to help overcome all these challenges:

• Instructional scaffolding: the teacher’s role is to keep the class focused on the objectives and reduce the risk of failing to achieve clear results. To avoid this, the teacher can provide manageable steps, model questions, research guides, and examples of final products.
• Clear assessment rubrics: clearly explaining what is expected of the process and the final product is essential. Clear rubrics provide reassurance to both teachers and students, facilitate grading, reduce bias, and help justify grades to families and school administrators.
• Targeted professional development: teachers must be adequately prepared to successfully implement the IBL methodology and better align it with the curriculum. Thus, they can participate in ongoing professional development, collaborate in professional learning communities, and seek instructional support from specialized coaches.
• Online proctoring and digital tools: the use of remote proctoring solutions with access controls, activity tracking, and filtered resources helps maintain academic integrity and better manage students’ independent work.

By combining these elements, schools and teachers can transform the challenges of inquiry-based learning into opportunities to create structured, safe, and sustainable learning environments.

At Smowltech, we are aware of the significant challenges posed by digitization in education, especially when schools incorporate the inquiry-based learning approach into online assessments and activities.

For this reason, we have developed proctoring plans specifically designed for the educational environment that help ensure tests are administered honestly and securely, protect academic identity, and help teachers and students maintain trust in digital assessment processes.
