Teaching style

believe learning is most powerful when it’s active, collaborative, and joyful. I integrate Information and Communication Technology (ICT) into lessons, pair students for peer mentoring, and design hands-on activities that encourage exploration. I love seeing students feel proud of their progress and eager to share their skills with classmates.
