This is an oldie but goodie! I have teachers ask me all the time where I learn about the digital tools I use in my classroom. Even though I rely on my personal learning network through Twitter, Pinterest, and even Instagram, I read a lot of articles about instructional technology.
My favorite source for these articles is the iOS app, Zite (also available for Android).
Zite is a personalized magazine. I started by putting in my interests, and Zite automatically generated articles around these interests that are current and up-to-date! When I choose an article and read it, I can then decide if I liked the article or not and what keywords interested me. Zite will further personalize the articles based on these responses.
