The producers of the movie "Screenagers: Growing Up in the Digital Age" have created a blog, "Tech Talk Tuesdays," to share research and resources about teenagers and screen time, plus suggestions for talking with teens about the effects of excessive consumption and setting guidelines. The posts tackle topics such as creating sensible policies for cell phone use in school, how much screen time is harmful vs. helpful, and problems associated with parents texting kids during school. Posts like "Groundbreaking Study on Association Between Screen Time and Brain Changes" keep educators current on what research reveals about teens and screens. Check out the blog.
