Demonstration, discussion, and illustrated lecture are all considered:

Demonstration, discussion, and illustrated lecture are all forms of presentation techniques used in instructional settings. These methods are designed to convey information and skills to learners in an effective and engaging way.

A demonstration allows the instructor to show a process or skill, providing a visual model that students can follow. Discussion encourages interaction and exchange of ideas, helping students to deepen their understanding of the material through conversation. An illustrated lecture incorporates visual aids to complement the spoken word, making it easier for learners to grasp complex concepts.

Each of these presentation techniques serves to facilitate learning by providing clear, structured information that supports the instructional goals. Being effective in presenting information is crucial for instructors aiming to enhance their students' comprehension and retention of the material.
