About Miguel Guhlin

Transforming teaching, learning and leadership through the strategic application of technology has been Miguel Guhlin’s motto. He is a veteran educator comfortable with modeling the use of technology at the classroom, campus, and district level. He earned his ISTE Certified Educator status--the first Texan and Panamanian to do so--in September, 2018. He has served as a Director of Technology Operations, as well as an Instructional Technology Director. He has renewed his commitment to finding research-based strategies that work and blending technology into them. A national and international presenter, a prolific writer with over one hundred publications in print, a regular columnist and blogger with thousands of pieces published online, Miguel blogs at Around the Corner and for TCEA’s TechNotes Blog.

Both blogs have received EdTech Magazine's Honor Roll of Must-Read Blogs for 2017 and 2018. Miguel earned both his Master’s degree in Bicultural/Bilingual Studies with an ESL Concentration and his B.A. at University of Texas, San Antonio.

Please note that my tweets, instagram/facebook posts, blog entries, podcasts, publications may or may not reflect the interests of my employer(s), their customers/clients. In fact, it's probably best to assume that they do not. I certainly do not craft them with that in mind. Often, my focus in sharing tweets is a natural by-product of saving items for later reading, not an endorsement, or "Wow, this is interesting and makes me think." For that reason, you are not entering an echo chamber but rather a space where ideas (some controversial in education and edtech) are considered, debated, and my imperfect thinking flushed out. After all, how else will I explore these ideas? That's what a blog is for, to more quickly identify the rightness or error of one's thinking and processes. By the way, see if the canary is still alive at the bottom of this post.

Canary in the Coal Mine

One of my favorite stories from the past includes that of the canary in the coal mine. According to Wiktionary:
An allusion to caged canaries (birds) that miners would carry down into the mine tunnels with them. If dangerous gases such as carbon monoxide collected in the mine, the gases would kill the canary before killing the miners, thus providing a warning to exit the tunnels immediately.

I share this image here. If for some reason it changes from what is displayed, you will know that there has been a chilling effect on my speech, on the content of the blog. As long as the canary lives, you know no one has said, "You will stop publishing this or suffer consequences." Who might level such a threat, I don't know, but I always wanted to put a canary in this space in case toxic influences find their way in.
