5E instructional model

The 5E instructional model moves students through five phases to build and further develop understanding. These phases are: Engage → Explore → Explain → Elaborate → Evaluate.
Initially developed by
Biological Sciences Curriculum Study (BSCS), Colorado, USA
Effectiveness
In 2023, Polanin et al. from the American Institutes for Research conducted a meta-analysis of 61 randomized control trial studies and found that the 5E instructional model had an effect size on student science achievement of 0.87. Download the research paper here.
Where you'll find it in Stile
Every Stile unit is informed by the 5E instructional model at a program, unit and lesson level.
Examples within Stile

Engage: stoking student interest

A live poll about students' earthquake experiences sparks curiosity and surfaces prior conceptions.
Introduction: Natural disasters lesson
in the Active Earth unit
Text: Poll: Have you ever experienced an earthquake? Image: Collapsed building after an earthquake, with poll options and student response results displayed.

Explore: active investigations

Students investigate why sunlight is weaker in winter by experimenting with flashlights and angles.
Modeling sunlight intensity lesson
in the Our Place in Space unit
Text: Investigate how the intensity of light on a surface depends on the angle of the light beam. Image: Students shining a torch at different angles onto graph paper using a protractor, measuring and drawing the light circles.

Explain: clarifying concepts

Students draw on learning experiences from the previous phases to explain key concepts. Teachers use these explanations to gauge student understanding and inform next teaching steps.
The fossil record lesson
in the Active Earth unit
Text: Summarize how the dinosaur fossils formed. Image: Illustration of buried dinosaur skeletons and remains in soil and water layers.

Elaborate: applying and extending knowledge

Students apply their knowledge of forces in a novel design task, demonstrating their grasp of the concept by extending it to a new context.
Long-distance communication lesson
in the Waves unit
Text: Discuss whether satellite internet could provide fairer internet access in the future. Image: Two students on a video call with Earth and an orbiting satellite in the background.

Evaluate: assessment and reflection

Students receive feedback on their thinking in this final phase. Teach Mode allows on-the-spot formative assessment during lessons, auto-marked check-ins provide prompt analysis of student understanding and summative tests offer a detailed view of student learning.
Test: The Hydrosphere lesson
in The Hydrosphere unit
Text: Label the features to complete the diagram. Image: Diagram of a landscape with rivers, lake, clouds, and groundwater, with labels to be placed on features.
