There are a lot of educational and educational technology journals and magazines out there. I have two favorites, both of which are free.
The first one is Tech&Learning magazine, which I am a TL Advisor for. I write a bi-monthly blog and do product reviews for them. The magazine has a lot of great articles and resources for teachers. They also run educational technology conferences around the country. The conferences are a great way for educators to see what is new and how to integrate technology into their classrooms.
The other one is THE Journal. THE Journal is another great resource with some really good articles, tips, and information for educators.
Both magazines also have great websites with a plethora of information. You can subscribe to either an electronic or paper version of the magazines.
The articles and information in both magazines are well written, timely, and relevent and well worth reading.
