* A defined curriculum: A set of learning objectives, topics, and materials that students are expected to cover.
* Regular meetings: Classes meet at scheduled times (e.g., daily, weekly) for a specified duration.
* Structured instruction: The instructor delivers the material using various methods (lectures, discussions, activities, etc.).
* Assessment: Students are regularly assessed to measure their understanding and progress (tests, quizzes, assignments, projects).
* A consistent group of students: Although there can be some fluctuation, the class generally consists of the same group of students throughout the course.
This contrasts with things like independent study, workshops, or irregular tutoring sessions, which are less structured and may not have all these features. In essence, a "regular class" is the standard model of classroom-based instruction.
