Linda Donohue

Learning Specialist - High School Prep Tutor

I have always been a lifelong learner and have enjoyed my participation in teaching and learning environments. With an Honours Bachelor of Science in Computer Technology , I worked for many years in Information Technology. My passion for teaching and learning was stimulated when I was hired as an Educational Technologist at a K-12 International school in the Netherlands. In that role I was responsible for ensuring that technology was integrated smoothly and effectively across the curriculum in all subject areas. In order to fulfill my mandate effectively I was required to learn the curriculum at the school, which offered the IGCSE, U.S. and Canadian curriculums. It was this experience that led me to enroll in a Master of Education program with the University of British Columbia, specializing in instructional design. My most recent teaching experience was working as a classroom teacher at a refugee learning centre in Malaysia where I was responsible for teaching Intermediate (grades 7-9) IGCSE math and science courses. I am excited to be working with Math Plus Tutors and look forward to helping students achieve success!
