From my own experience, the most effective digital tools are provided by the British publishing house Pearson, which accompany their ELT resources. There are tools for teaching English online as well as MyEnglishLab for students to fulfill their home tasks and to be in contact with the teacher's account.

To my experience, the most effective method is face to face experience

For promoting personalized learning in ESL classrooms, a few digital tools stand out for their effectiveness. Kahoot is excellent for making learning fun and interactive, allowing teachers to create quizzes that adapt to each student's pace, giving them instant feedback based on their performance. Flipgrid is another powerful tool, where students can record and share videos of their speaking exercises, receiving personalized feedback from teachers. It encourages self-expression and helps improve speaking fluency. Moodle offers a more comprehensive platform where teachers can customize learning paths for each student, assigning tasks and resources based on their individual progress. These tools allow students to work at their own level and pace, promoting a more tailored learning experience that fits their unique language needs.
