My CALL Experience I have been tutor for 4 years, more than 10 students in total, aged from 5 years old to 15 years old. I will give them different materials based on their needs. Personally, I prefer to teach students who are still in the elementary school because they do not need to suffer too many pressure from the education system. Take one of my students, Mary, for example. She is fifth grade now, and I like to talk tales with her, watching movies, YouTube in order to improve her English speaking and listening skills.
