Which of the following is considered inexpensive and effective for small group presentations?

Choosing flip charts for small group presentations is an effective and economical option due to their simplicity and interactivity. Flip charts allow presenters to write or draw in real time, which can enhance audience engagement and understanding, especially in small group settings. They facilitate spontaneous discussions, brainstorming sessions, and personalized feedback, making it easier for presenters to tailor their content based on the group's reactions and input.

While presentations using PowerPoint slides can be visually striking and informative, they often require additional technology and preparation. Brochures and posters serve as supplemental materials but may not provide the level of interaction and immediate engagement that flip charts offer. Thus, for small groups where direct interaction and adaptability are crucial, flip charts stand out as the most suitable choice.
