Dryden began her teaching career in 1937, near the rural community of Lenore,
Manitoba. She taught at the Errol School, a one-room building with an outhouse and wood stove. After five years of office work, she returned to her former career in 1947, teaching at Two Creeks School and later Virden Public School, both located in her home province. While there, she also helped define the curriculums for the Industrial Arts and Vocational Industrial programs, as well as being introduced to early computer systems. She currently teaches four times per week at the "Creative Retirement Learning Centre" and the "Chinese Cultural and Community Centre" in
Winnipeg,
Manitoba. Dryden offered introductory classes in computer technology and
Microsoft Office software, as well as explaining how to send emails and stay safe online. She taught on numerous operating systems, from Windows 97 to Windows 10, while managing the bugs that come with new releases. Keeping pace with technological changes, necessary for her computer classes, involved plenty of work for Dryden. However, she still enjoyed "... working with people, and watching them as the learning process goes on." In order to advance, she believed that students need to develop their minds, bodies and spirits. With regards to computers and seniors, she felt that using technology keeps the brain active and also allows retirees to keep in touch with loved ones. Dryden also saw a negative side to new technologies, considering how many people now focus on their cell phones when they could be connecting with others. ==Awards and honors==
