Teaching methods can be categorized as teacher-centered or student-centered.
In teacher-centered methods, the teacher is the active dispenser of knowledge, and students are primarily passive recipients.
The Lecture method is the quintessential example of a teacher-centered approach. The teacher presents information to the class with minimal student participation.
In contrast, Problem solving, Project, and Observation methods are student-centered. They require students to be actively involved in investigating, creating, discovering, and constructing their own knowledge.
Therefore, the lecture method is the teacher-centered method among the options.
