The 5E Instructional Model is a lesson sequence in five phases: Engage, Explore, Explain, Elaborate and Evaluate. Learners meet a puzzle and try things before the teacher introduces the formal idea. It was developed by BSCS (Biological Sciences Curriculum Study), with Rodger Bybee and colleagues, and has been used in BSCS curriculum materials since the late 1980s. It builds on the learning cycle of J. Myron Atkin and Robert Karplus (1962) and the SCIS cycle of Karplus and Herbert Thier.
How the five phases work
Where you see it today
BSCS says the model has been used extensively in its curriculum materials and teacher professional learning since the late 1980s, and that several US states endorse it. In a randomised laboratory study, students aged 14 to 16 taught with 5E-based materials scored higher on knowledge, reasoning and argumentation than peers taught with commonplace methods by the same teacher (Wilson et al., 2010).
A field experiment with high school maths students found that open access to GPT-4 raised practice scores but lowered exam scores once access was removed; a tutor version with guardrails largely avoided the harm (Bastani et al., 2025). The 5E lesson: an assistant that hands over answers skips the Explore and Explain phases where learning happens.
A randomised trial with college students compared a custom AI tutor, designed on the same teaching practices as the class, with an in-class active-learning lesson. Students learned more in less time with the tutor (Kestin et al., 2025). It was one course, so treat it as promising rather than settled.
The same order works for adults: a real customer problem first (Engage), a sandbox or simulation (Explore), a short debrief that names the method (Explain), a live task (Elaborate), then a review against clear criteria (Evaluate).
5E vs related teaching models
How to use it
- Open with a question or puzzle that makes people state what they already believe, and write those beliefs down.
- Give a concrete task to explore before you explain anything; resist the urge to give the answer early.
- Ask learners to explain their findings first, then introduce the formal concept and terms using their examples.
- Set a transfer task in a new context so the idea is used, not just recalled.
- If you use an AI assistant in class or training, configure it to ask questions and give hints rather than full answers during Explore.
AI makes explanations cheap, so the scarce part of learning is the effort the 5E sequence protects: trying, getting it wrong and explaining it back. The Business Engineer view is that teams which design their AI tools around that order build skill; teams that use AI to skip it build dependence.

Understanding the 5E Instructional Model
At its core, the 5E Instructional Model helps students understand new concepts in the classroom through active participation. By understanding and then reflecting on certain activities, students are better able to reconcile new knowledge with existing ideas.

The 5E Instructional Model is a five-phase lesson sequence (Engage, Explore, Explain, Elaborate, Evaluate) developed by BSCS in the late 1980s.
The model is a form of inquiry-based learning, encouraging students to discover information for themselves instead of having the teacher reveal information directly.
While the framework should be followed in a linear fashion, the teacher may need to move back and forth between phases to ensure students understand and retain knowledge.

The model is a form of inquiry-based learning, encouraging students to discover information for themselves instead of having the teacher reveal information directly.
It is based on research conducted by science educators J. Myron Atkin and Robert Karplus in 1962.
Both argued the inquiry-based approach was more valid in science teaching, which until that point had been dominated by the rote memorization of facts.
The inquiry based-approach is a multi-faceted approach incorporating
- The posing of questions and the planning of investigations.
- The examination of books and other sources of information to understand what is already known.
- The evaluation of known knowledge in light of experimental evidence.
- The utilization of tools to analyze and interpret data, and
- The formation or proposing of answers, explanations, predictions, and results.
The 5E Instructional Model framework
To assist the teacher and the student in learning, both must move through a framework of five phases.
While the framework should be followed in a linear fashion, the teacher may need to move back and forth between phases to ensure students understand and retain knowledge.
Each phase begins with the letter E:
Engage
First, the teacher must understand the level of prior knowledge students possesses on a certain topic.
Then, they must identify any knowledge gaps.
Perhaps most importantly, the teacher needs to foster an interest in filling these gaps by ensuring students are in the right frame of mind to learn.
Explore
This phase provides students with a learning experience where they hypothesize, investigate, question, test, or communicate with their peers.
The teacher must avoid giving direct instruction during this process. Students should be free to conceptualize and collaborate in an informal setting.
Explain
Then, students describe their understanding of a topic and pose questions stimulated by their learning in the previous phase.
They must be allowed to express their own ideas and explanations before the teacher introduces factual scientific information.
Any misconceptions are clarified with definitions, notes, labels, videos, software, or other relevant informative materials.
Elaborate
During the elaborative phase, students are given the space to apply what they have learned while reinforcing previous knowledge.
Ideally, knowledge is broadened and deepened through further investigation, product creation, technology integration, or the application of knowledge or skills to other disciplines.
Evaluate
Traditional forms of assessment involve examinations that test rote learning. However, the 5E approach favors both formal and non-formal evaluation methods.
This may include a portfolio or performance-based assessment, concept maps, physical models, or journal logs. In some cases, the student may also be allowed to self-assess or be assessed by their peers.
Drawbacks of Using the 5E Instructional Model
While the 5E Instructional Model offers many advantages, it also has some limitations and potential drawbacks:
1. Time-Consuming
Implementing all five phases of the model can be time-consuming, and educators may not always have the necessary time for in-depth exploration.
2. Complex Planning
Designing lessons using the 5E model requires careful planning to ensure that each phase aligns with the learning objectives.
3. Variability in Engagement
The effectiveness of the “Engage” phase in capturing learners’ interest may vary depending on the topic and the instructor’s approach.
4. Resource-Intensive
Some activities in the “Elaborate” phase may require additional resources, which might not always be readily available.
5. Not a One-Size-Fits-All
The 5E model may not be suitable for all subjects or instructional goals and may require adaptations for certain topics or learners.
