When giving an interactive lecture, which of the following is essential to use?

In an interactive lecture, the use of clarification is essential because it ensures that students fully understand the content being presented. When instructors encourage students to ask questions and provide clarification on complex topics, it fosters an engaging learning environment. This interaction helps to address any confusion or misconceptions, enabling students to actively participate and absorb the material more effectively. Clarification also encourages dialogue, which is critical in an interactive setting where learners feel comfortable expressing their thoughts and inquiries.

Other factors, such as analogies, examples, visual aids, and humor, can enhance the teaching experience, but they are not as fundamentally essential to the interactive nature of the lecture. While these tools can help in illustrating concepts and keeping students engaged, without proper clarification, the core goal of effective communication and understanding may not be achieved.
