Instructor Biography

Steven Gardiner, Online Instructor and Mathematics teacher

I have been teaching mathematics for over seven years and am excited about teaching students how to get more out of using technology for learning, specifically their calculator. I started The Calculator Guide, a growing collection of videos and resources in February 2015 and am happy to be developing courses online and on Udemy.

I have recently completed an MSc in Mathematics Education where my dissertation examined students perceptions and knowledge of a Natural Display Calculator and explored new ways of using the calculator to help students and teachers.
