Thoughtful and professional comments are welcome on the posts at GeoEd Trek to encourage a virtual community among geoscience educators. We can all benefit from a continued conversation and sharing of related resources. Comments that disagree or provide a contradiction to an original post are allowed as long as the tone is professional and constructive. Your full name and email address are required with each comment before it will go live. By submitting a comment, you are giving me your permission to post your words. I reserve the right to remove any comments that are presented in a hostile or aggressive tone, contain unsupported accusations, or that are completely off topic. Comments with threats, profane language, or personal attacks against anyone or any group will not be allowed. I will allow comments from educators that provide feedback on the use of a particular educational technology tool or product, but I will not allow comments that are solely promotional/commercial in nature. Spammers – don’t even think about it.
