Teachers for radio and television take on the role of instructors through microphones and cameras, writing content for students and coordinating with specialists and producers to create broadcast programs. Producers are responsible for overseeing the entire production process from concept to broadcast, working with various media technicians like camera operators, sound engineers, and editors. The production process involves developing an idea, researching the topic, writing a script or screenplay, rehearsing, recording the final program, and editing it with graphics, animations, and text elements before broadcast.
