Denzil Mackrory

STEM Learning Leader

Denzil Mackrory joins STEM Innovation Academy as the STEM Learning Leader. He has received a Bachelor of Education from the University of Kwa-Zulu Natal in South Africa, Masters of Science from the Open University in England and a certificate in STEM Leadership from Columbia University.

Denzil has spent his career teaching in the International school circuit. Most recently he taught at the International School of Kenya where he developed and implemented the STEM curriculum. In developing curriculum, he aims to integrate the STEM disciplines by engaging students in authentic, real world learning activities that address issues of global significance.

Whilst it is imperative to produce global minded citizens, it is equally important for students to be connected to their local communities. He believes that the school is the starting point for learning and that it must be taken beyond the walls of the school by forging learning partnerships with the local community.

He strongly believes that learning must not only be fun but also rigorous. The real joy of learning comes from the feeling of success and accomplishment when overcoming a challenge. Denzil prides himself in developing a differentiated curriculum that allows students of varying abilities to be appropriately challenged to experience success in learning.

Denzil is also deeply connected to nature. Being new to Alberta he spends his free time exploring, travelling and camping in his rooftop tent. He is a wildlife photographer, mountain biker and keen fisherman who loves spending time outdoors with his friends and family. Life is about balance, knowing when to pick up the phone and when to turn it off.
