Two Categorizations of Discovery Learning

Two different categorizations exist. A teacher should know both.

A teacher who knows the categorizations can recognize discovery learning in many forms. A teacher who only knows one definition may miss valid forms of discovery learning.

Why categorizations exist

Educational researchers and writers categorize discovery learning differently. There is no single “correct” classification. Two main ones.

Why does this matter? Because:

1. Teachers reading different sources may encounter different categorizations.
2. Each categorization highlights different aspects.
3. Different aspects fit different teaching contexts.
4. Knowing multiple categorizations builds flexibility.

A teacher with only one mental framework may miss valid types. A teacher with multiple frameworks sees discovery learning in many places.

Categorization 1

Categorization 1 includes:

Experiments

Experiments are discovery learning. Students:

1. Set up an experiment.
2. Conduct it.
3. Observe results.
4. Discover knowledge.

The discovery may be:

1. The intended scientific finding.
2. Unexpected results.
3. Procedural insights.
4. Better methods for next time.

Experiments produce discovery whether they “succeed” by their original aim or not.

Exploration

Exploration includes:

1. Treasure hunts.
2. Puzzles.
3. Investigations of physical environments.
4. Searches for information.

Whenever students search, find, and discover, they are exploring.

Simulation-based learning

Simulations are computer-based environments where students:

1. Run scenarios.
2. Test outcomes.
3. Discover patterns.
4. Build understanding.

Modern simulations include:

1. Physics simulators.
2. Chemistry visualizations.
3. Historical simulations.
4. Economic models.
5. Ecological systems.

Students interact with the simulation and discover how the modeled system works.

Problem-based learning, inquiry, and web quests

Some categorizations include:

1. Problem-based learning. See /methods-of-teaching-study-guide/problem-based-learning/ for the full method.
2. Inquiry-based learning. See /methods-of-teaching-study-guide/the-inquiry-method/.
3. Web quests. Online inquiry projects.

These are sometimes classified as types of discovery learning. Sometimes they are classified as separate methods.

In this guide, PBL and inquiry are separate chapters. But scholars who put them under discovery learning are not wrong. They are using a broader definition.

Why some scholars distinguish

The argument:

Inquiry: students gather data themselves, then interpret.

Discovery: information is given to students; they discover patterns and conclusions in the given information.

For example:

Inquiry: ask students to interview their families about food traditions.

Discovery: give students a set of food tradition cases and ask them to find similarities and differences.

The first has students collecting data. The second has students given data.

A scholar who distinguishes treats these as different methods. A scholar who combines treats them as variations of one method.

Either approach is fine. The teacher should know both perspectives.

Categorization 2

Categorization 2 includes:

Case-based learning

Students receive cases. They analyze. They discover conclusions.

The teacher prepares several cases:

1. Case 1: a child with all healthy habits.
2. Case 2: a child with mostly healthy habits but missing one.
3. Case 3: a child with poor habits.
4. Case 4: another variation.

Students analyze the cases. They discover:

1. What healthy habits look like.
2. Which case is best for health.
3. Which habits matter most.
4. How their own habits compare.

The discovery is in the analysis. Students are not told the conclusions. They figure them out.

Another example: pictures from different cities. Students compare. They discover:

1. Differences between cities.
2. Common transportation issues.
3. Patterns across the country.

This is case-based discovery learning. Students learn by comparing real cases.

Incidental learning

1. Treasure hunts.
2. Word puzzles. Hide words in a grid; students find them.
3. Sudoku. Number puzzles where students discover what fits.
4. Math puzzles. Numbers hidden in patterns.

Sudoku is incidental learning at its core. Students discover the right numbers through logic and trial.

Some PBL is discovery (when students discover the solution). Some is not (when steps are predetermined). The line is blurry.

Learning by exploring

Learning by exploring focuses on questions. Students:

1. Encounter something unfamiliar.
2. Ask questions.
3. Explore to find answers.

The bag example from earlier:

Students reach into the bag. They feel objects. They identify what they are. The discovery is the identification.

A variation: students reach into a sealed box and describe what is inside without seeing. This is exploring through senses.

Learning by reflection

In learning by reflection:

1. Student asks a question.
2. Teacher does not answer directly.
3. Teacher asks more questions.
4. Student reflects and answers.
5. Through this exchange, the student discovers the answer.

The teacher uses questions to guide thinking. The student discovers the answer through their own reasoning.

This is the Socratic method. The teacher does not tell. The student discovers through guided reflection.

Flashcard

What is learning by reflection in discovery learning?

Answer

The teacher answers a student’s question with more questions until the student discovers the answer

A child asks why the sky is blue. The teacher does not answer directly. Instead: What colour is sunlight? Are the seven colours’ wavelengths the same or different?

The student reasons through the questions and reaches the answer themselves. The discovery comes through guided reflection, not from the teacher.

Simulation-based learning

Same as in Categorization 1. Computer-based simulations where students explore modeled systems.

Includes:

1. Building simulations.
2. Running simulations.
3. Modifying simulations.
4. Discovering patterns.

A student building a simulation of an ecosystem discovers how the ecosystem works as they build it.

How the categorizations relate

Both categorizations share simulation-based learning. Otherwise they differ:

The categorizations highlight different things:

Categorization 1 emphasizes broad categories that include other methods (PBL, inquiry).

Categorization 2 emphasizes more specific learning approaches.

A teacher can use either. Or both. Or neither, treating discovery learning as a single approach.

Bruner’s contribution

Jerome Bruner is the major theorist of discovery learning. His key claim: children naturally discover.

This is consistent with images of the child covered earlier in this guide:

1. Children as natural discoverers (Bruner).
2. Children as active learners (Piaget, Vygotsky).
3. Children as inquirers (constructivism).

If children are natural discoverers, schools should support discovery, not suppress it. Discovery learning aligns with this view.

A teacher who believes in students’ natural capacity for discovery uses discovery learning effectively. A teacher who believes students must be told everything resists discovery learning.

Flashcard

What are the two categorizations of discovery learning?

Tap to reveal

Answer

Categorization 1: experiments, exploration, simulations, PBL, inquiry, web quests. Categorization 2: case-based, incidental, exploring, reflection, simulation.

Both are valid. Different scholars classify discovery learning differently.

Categorization 1 includes broader categories (PBL, inquiry). Categorization 2 includes more specific learning approaches.

A teacher can use either or both. Knowing multiple categorizations builds flexibility.

What teachers should do

Practical advice:

1. Don’t worry about strict categorization. Different scholars use different categories. Either is valid.

2. Recognize discovery learning in many forms. Whatever the category, look for the spirit of discovery.

3. Use multiple types. Variety serves students better than only one type.

4. Match type to content. Some content fits experiments. Some fits cases. Some fits exploration.

5. Read both perspectives. Some books use Categorization 1. Some use Categorization 2. Both are useful.

A teacher who is flexible across categorizations finds discovery learning in many places. A teacher rigid about one categorization may miss types that fit specific contexts.
