Seminar vs. Lecture: What's the Difference?

Edited by Janet White || By Harlon Moss || Updated on October 11, 2023
A seminar is a form of academic instruction, often involving a discussion among a small group. A lecture is a discourse on a particular subject given before an audience or a class, especially for instruction.

Key Differences

A seminar typically encourages interactive discussions among participants. In contrast, a lecture is generally a presentation given by a speaker to convey information or teach about a particular subject.
Seminars usually involve smaller groups where everyone can participate. Whereas lectures often involve a single speaker imparting knowledge to a larger audience, without expecting interactive participation during the presentation.
Seminars can often allow for a back-and-forth exchange of ideas between the presenter and the audience. On the other hand, lectures usually involve a one-way communication flow from the lecturer to the audience.
In a seminar, participants might prepare material in advance and expect to engage in discussion. Lectures, however, are generally structured with the audience passively receiving information and perhaps asking questions at the end.
