Face-to-face (F2F) vs Online Discussions

First topic message reminder :

If you have experienced discussion through F2F and online, what is your comment on the two different discussion settings? Which one do you prefer and why? Any suggestions to improve?

i prefer more online discussions than f2f.. because i felt really awkward when i'm speak in english in front of the public, moreover i cannot think the word that i'm going to say because f2f is spontaneous.

when i speak english, it sounds weird. and it's embarassing me.

i like to join online discussions if there is a topic that i'm familiar with for example family and for f2f, i need a teacher's guidance because i don't know how to voice out my idea

to speak in public, I need guidance from the teacher to correct my grammatical errors and help me in improving ourselves to be more confident

I prefer an online discussion if the teacher told my grammatical errors and teach students grammar is often wrong, and as well as telling the facts or current information

i think f2f can improve our communication skill. i'm a shy girl and for me to improve this, i have to practice more because practice makes perfect. my mum is very fluent in english so i can practice speaking with her.
i love my mum..
