This is the seventh interview in our thought-leadership series featuring teachers who work at 51Talk. Meet Serena Correnti and learn from her experience and insights as an ESL instructor.
Serena, please tell us about your educational background.
In 2014, while I was still a high school senior, I completed a TESOL course at the Canadian Institute of English in Atlanta, Georgia. That training introduced me to modern, research-based ESL teaching methods designed to engage multiple parts of a student’s mind. The course emphasized practical techniques that help learners of all ages stay motivated and retain more of what they learn.
How did you come to teach at 51Talk?
It happened quite unexpectedly. I received an email inviting me to apply, even though I already had a job elsewhere. While I was doing well in that role, the pay was limited. After researching 51Talk and discussing the opportunity with my husband, I decided to make the change. At first I worried about rebuilding my student base and about the transition to a different platform.
Admittedly, I didn’t pass my first interview. However, a supportive 51Talk staff member named Sally recognized my potential and gave me a second chance. I’m grateful she did—within a short time I had a full schedule of classes. Joining 51Talk has been a positive turning point in my teaching career.
You’ve mentioned an interest in whole-brain teaching. Can you explain what that means and how you apply it in class?
I first learned about whole-brain teaching during my TESOL training. The basic idea is to involve as many parts of the learner’s brain as possible so lessons are memorable and engaging. This is especially important with children, whose attention can decline quickly—often after about twenty minutes. By activating multiple senses and modes of thinking, teachers can keep students focused and help them retain more.
In practice I use Total Physical Response (TPR) to incorporate movement, bring toys and props into lessons, add humor, and include songs and short videos. These strategies make lessons active and fun, and they work well with adult learners too. When students are laughing, moving, and responding, they learn more naturally. Parents notice the difference and often tell me their children don’t want the lesson to end, which is one of the greatest rewards for a teacher.
Some teachers are hesitant to teach online or to work across cultures. How can they overcome those fears, and do you have tips for teaching students from different cultural backgrounds?
It’s natural to feel nervous about teaching online or interacting with learners from another culture. Often the students are nervous too, especially if they’re unfamiliar with online lessons. The best approach is to be open-minded and compassionate. Try to see things from the students’ perspective, and be patient as everyone adjusts. When you open your heart and mind, you’ll gain far more than you give: you’ll meet kind people and learn about different customs and ways of thinking.
Practical tips include preparing visual aids and props, pacing lessons to allow for comprehension, using clear, friendly language, and encouraging interaction so students feel comfortable. Small routines—like a warm greeting, a simple review, and a fun activity—help build rapport across cultural differences.
What key advice would you offer educators considering a role at 51Talk?
My favorite saying is: “The best teachers teach from the heart, not from the book.” You don’t need advanced degrees or decades of experience to be an effective online teacher. I was only 21 when I started at 51Talk, and I was unsure of myself. What helped most was being genuine and treating my students like friends. Showing that you care—asking about their day, encouraging their efforts, and being supportive—goes a long way.
Finally, what is your favorite part of a typical ESL lesson and why?
I love singing with my students, even though I wouldn’t call myself a great singer. Playing a short, familiar song in class can instantly lift a child’s mood and motivate them to participate. I also enjoy being playful—using exaggerated facial expressions, silly voices, and a sense of fun brings out the students’ enthusiasm. Parents appreciate seeing their children happy and engaged, and for me, being able to laugh and teach every day makes this a truly fulfilling career.
