What is a discourse or formal presentation given before a group of learners for instruction called?

A formal presentation given before a group of learners for instruction is called a lecture. This term specifically refers to a method of teaching where an instructor delivers a structured presentation on a specific topic, often using visual aids and accompanying materials, to impart knowledge to the audience.

In a lecture, the primary focus is on the instructor conveying information, theories, or concepts, allowing students to absorb material in a systematic way. This format is commonly used in educational settings, including universities and training programs, to cover foundational subject matter.

While other options may involve educational activities, they do not carry the same level of formality or structure as a lecture. For instance, seminars typically encourage participant interaction and discussion, workshops emphasize hands-on learning and practice, and discussions focus on exchanging ideas among participants rather than a single individual's presentation. Each of these serves a different pedagogical purpose, whereas a lecture is distinctly characterized by its instructive and informative nature.
