PEACE TALKS RADIO host Paul Ingles postulates that advertising of all kinds crowds our brains with messages that may not help us to inner peace or peace among us. Many of us just let TV, radio and online ads wash over us in our homes, cars and through our devices. We talk with three media educators who think teaching young people and adults to critically analyze ad messages may help us build some immunity to the persuasive power the ads ply to our minds, and to our attitudes about ourselves or each other. We'll ask our guests, media literacy advocates and teachers, about it. And while the idea of teaching media literacy in schools has been kicked around for about 25 years, to promote critical analysis by students of advertising and other mediated messages, the movement hasn't really taken off.
