In which instructional phase do instructors assess prior knowledge before teaching?

The phase in which instructors assess prior knowledge before teaching is the preparation phase. This phase is essential because understanding the learners' existing knowledge helps instructors tailor the lesson to meet students' needs. During preparation, instructors can gauge what students already know, identify any gaps in their understanding, and adjust their teaching strategies accordingly. By doing this, instructors can create a more effective and engaging learning environment, ensuring that the material presented is relevant and comprehensible.

In contrast, the presentation phase focuses on delivering content, the evaluation phase is about assessing learners' understanding after instruction, and the application phase emphasizes practical use of the knowledge gained during the lesson. The preparation phase is crucial for setting a solid foundation for these subsequent steps in the instructional process.
