Teachers can use various audio, visual, and digital technologies in the classroom to engage students and accommodate different learning styles. For example, teachers can use CD players for listening activities, internet radio for educational music and news, overhead and digital projectors to display materials visually, and DVDs and digital video cameras to incorporate video lessons and student projects. When preparing presentations, teachers should determine their topic, conduct research, create an outline, organize information into clear and readable slides with limited text and engaging visuals, practice their speech, and present with confidence while engaging their audience.
