Academic cheating seems to be growing at an ever alarming rate. Cheating occurs at every level of education and certification and it includes students, educators, and administrators. Technology has also given cheaters new methods for cheating and, unfortunately, you can find most of these methods demonstrated on YouTube (you can find additional resources on cheating HERE).

Best College Reviews created an interesting infographic about cheating in high school and college that I wanted to share with you. They provide resons for cheating and how cheating occurs among other interesting factoids.

Please take a look at their website to find additional resources on cheating (listed below the infographic).

Oklahoma State University and the Oklahoma Department of Career and Technology Education invite you to watch their digital forum entitled "Educating for Global Coompetitiveness" on Friday, June 13, 2014 (Speakers are from 8:30 a.m. - 12:15 p.m. CST).

Featured speakers are OSU President Burns Hargis, CareerTech State Director Dr. Robert Sommers, Tom Vander Ark, and David Cillay.

I've had the opportunity to previously meet and discuss customized learning with Tom Vander Ark, author of Getting Smart: How Digital Learning is Changing the World and CEO of Getting Smart, a education advocacy firm, but I'm excited to hear his newest thoughts on the subject and how learning is becoming more competency-based.

Dr. Cillay, Vice President of WSU Global Campus, led the 2012 launch of the Global Campus, which includes WSU’s online degree program. His responsibilities include expanding WSU’s market share, supporting faculty in technological innovation and using e-learning tools to ensure that WSU remains open and accessible. I'm also excited to learn from this presentation as it should add great value to what we are trying to accomplish with digital delivery at the Oklahoma Department of Career and Technology Education.
