The lecture method is the oldest teaching method where the teacher actively explains topics to passive but attentive students. It has several purposes such as motivating students, clarifying concepts, reviewing material, and expanding understanding. Effective lecture planning involves determining the aim, objectives, content, and structure. During a lecture, the teacher engages students through discussion, demonstrations, illustrations, and examples. They conclude by asking questions and summarizing key points. Characteristics of a good lecture include an active teacher, logical organization, clear delivery, and use of visual aids and humor. Advantages are that it is economical, imparts factual information, guides student thinking, and allows coverage of abstract topics.
