We have to select good tamil teachers to develop tamil langulage. Most of the tamil teachers are using tamil bazar notes to teach tamil. Using tamil notes should be avoided. Students memorisng as it is from the notes and the teachers are awarding 100% marks. It an idiotic system.
I am teaching tamil.So far i am not encouraging my students to learn from tamil bazar notes.Instead I encourage all my students to create and write own answers.
so true. i can say i have taken tamil classes times in my life and i have never had a teacher who was worth a tablespoon of salt. which is why so many people who take tamil as their second language can’t even read a newspaper.
Nice&helpful
