Which term refers to the explicit demonstration of a strategy or concept by the teacher?

The term that refers to the explicit demonstration of a strategy or concept by the teacher is modeling. In an educational context, modeling involves the instructor showing how to perform a particular task or use a specific strategy, often accompanied by verbal explanations and demonstrations. This process aids students in grasping new concepts by providing them with a clear example of what is expected and how to achieve it.

Modeling is particularly effective because it not only conveys the correct procedure but also often includes thinking aloud, allowing students to understand the thought processes involved in applying the strategy. As a result, students can observe and replicate the action, which enhances their learning and reinforces their understanding of the material.

In contrast, the other terms listed do not pertain to the concept of teacher demonstration in the same way. A morpheme refers to the smallest meaningful unit of language, orthographic units pertain to the writing system and spelling conventions, and narrative text refers to a type of writing that tells a story. Therefore, these options do not accurately represent the idea of a teacher explicitly demonstrating a strategy or concept.
