Volunteering as an online English teacher with Horizon Asia Educational Association (HAEA) means leading or supporting a Zoom-based ESL class for students in rural Malaysia, Myanmar, or Thailand, with no teaching credential and no travel required. It runs through HAEA’s Digital Education program, which is 100% volunteer-led and reaches students in villages where an in-person classroom isn’t practical.
Here’s what a class actually involves, who currently volunteers, what you need to get started, and the in-person alternative if you’d rather teach from Koh Tao instead.
Horizon Asia Educational Association’s Digital Education program is 100% volunteer-led, delivering free Zoom-based ESL and science classes to students in rural Malaysia, Myanmar, and Thailand since at least December 2021, when twice-weekly science and geography classes launched for Semai children in Pos Woh village.

What Zoom teaching actually involves
HAEA’s Digital Education program runs three types of Zoom classes: ESL lessons for students of all ages, building the language skills that open access to further study; science classes covering biology, physics, and astronomy, often for students encountering these subjects for the first time; and Happy Readers, a literacy and human rights awareness program run in partnership with Perak Women for Women (PWW).
A concrete example: HAEA’s Zoom science and geography classes for Semai children in Pos Woh village, Malaysia, launched in December 2021, running twice weekly with bilingual volunteer teachers and materials built specifically for students who had never attended formal school before. On the mentoring side, American educator Claire Robinson joined HAEA’s mentorship program in September 2024, giving two students, one from Myanmar and one from Malaysia, personalized ESL and Math tutoring over Zoom every Tuesday and Thursday.
The format varies depending on which program you join. A group ESL class run through Digital Education looks closer to a regular school lesson, with vocabulary, grammar, and conversation practice for a set group of students who return week after week. A mentorship match through the Mentorship for Gifted Students program is closer to one-on-one tutoring: a single volunteer paired with one or two students on a fixed weekly schedule, sometimes alongside a sponsored course on a platform like Outschool.com. Both formats depend on the same thing: a volunteer showing up on the same day, at the same time, consistently.
Who volunteers
HAEA’s online volunteers come from a range of backgrounds, not just education. Rawane Abdaoui, from Morocco, has an engineering background and teaches ESL, science, and math; one student describes her classes as helping her “believe I can achieve anything.” Claire Robinson, an American educator, teaches ESL and math one-on-one via Zoom. Neither started as a professional classroom teacher in the country where their students live; both built a regular weekly slot around students they’d never meet in person.
What’s needed to start
On the student side, HAEA supplies what a Zoom class depends on where it’s missing: tablets or phones, solar charging equipment in areas with inconsistent electricity, and monthly internet subscriptions. On the volunteer side, you need a reliable internet connection, a computer or laptop with Zoom, and a weekly time slot you can commit to consistently. The program’s own teaching philosophy treats a predictable schedule as central to how students build confidence, not as an optional extra.
Online volunteers commit to a minimum of four weeks. Applying is simple: a short application review, followed by an online interview.
How to start
Apply to volunteer through HAEA’s volunteer page, or email info@horizonasia.org directly. From there, you can offer your time toward ongoing Zoom classes, contribute a specific skill (marketing, design, or fundraising support for HAEA itself), or ask about a personalized mentorship match like Claire Robinson’s, teaching one or two students on a set weekly schedule.
Prefer to teach in person? Koh Tao, via Wonderland
If you’re already planning a trip to Koh Tao, Thailand, you can teach in person instead, at Wonderland Jungle Hostel, HAEA’s operational base for the island. The hostel’s common-area classroom runs 12 weekly English and GED-prep classes for local children and young adults, and more than 50 hostel guests volunteer as teachers there each year, with no prior teaching credential required. In-person volunteers can combine teaching with a stay at the hostel, making it possible to volunteer for an afternoon or a season depending on how long you’re on the island.
Some of HAEA’s most visible in-person teachers started out as short-stay guests: Maroezka Williams, who brought a hospitality and tourism background to weekly Koh Tao classes, and Cherry, a former HAEA student who now teaches younger Myanmar students herself. Neither route, online or in person, is treated as the “real” way to volunteer. HAEA runs both because a student in a rural village and a student on Koh Tao need the same thing: someone who shows up.
FAQ
Do I need teaching experience to volunteer online with Horizon Asia?
No formal teaching qualification is required; current volunteers include an engineer and an educator, both teaching ESL, science, or math via Zoom. Teaching experience helps, but each application is decided case by case. Because our programs work closely with girls and young women in culturally sensitive communities, we currently accept female volunteers.
What equipment do I need to teach online?
A computer or laptop with a reliable internet connection and Zoom access.
How much time do I need to commit each week?
It depends on the program and your availability. Some volunteers teach a couple of sessions a week, and mentorship matches like Claire’s run on a fixed Tuesday and Thursday schedule. We’ll agree a schedule that works during your interview. The one thing we ask is a minimum commitment of four weeks, so students get real continuity with their teacher.
Can I volunteer online and also visit Koh Tao?
Yes. Many volunteers do one or the other, but there’s no requirement to choose. You can teach a regular Zoom slot and, separately, pick up an in-person class at Wonderland Jungle Hostel if you visit Koh Tao.
