OK to share printed TechRepublic Info?

I have a question concerning the copyright on the information TechRepublic has available through the internet.
I work for a non-profit healthcare organization as a computer instructor. I have found useful tips and articles and would like to sharethe printed material with my students.
Those of most interest are e-mail etiquette, manipulating data with Excel pivot tables, and various program tip sheets. I noticed the copyright at the end and was wondering if I need permission to do this.
