Concept

The 5E Instructional Model organizes inquiry-based teaching into five sequential phases: Engage, Explore, Explain, Elaborate, and Evaluate, each serving a distinct pedagogical function within a lesson.

Application

The stem describes a teacher delivering lectures on key concepts that lead to student discussion: formal, direct instruction on content followed by dialogue that consolidates and clarifies understanding. This sequence is the defining function of the Explain phase, in which formal vocabulary and concepts are introduced (often through direct teacher input) and refined through structured discussion.

Contrast

• Engage: opens the lesson with a question, anecdote, or short activity that activates curiosity and prior knowledge, before any formal content is presented, unlike the stem, which describes formal-content delivery itself.

• Explore: involves student-led, hands-on investigation of a phenomenon prior to the introduction of formal terminology, unlike the stem, which describes teacher-led lecture rather than student investigation.

• Elaborate: applies a concept that has already been introduced to a new or extended situation, unlike the stem, which describes the initial teaching of the concept rather than its later application.

Therefore, delivering lectures on key concepts that lead to student discussion is an example of the Explain phase of the 5E Instructional Model.
