Ma'am this is indeed an idea which has worked for us perfectly. Students feel free to post their ideas and voice their concerns freely. When many teachers are not comfortable sharing their personal phone numbers with students. We at R.N Podar are friends with so many students of face book. It definitely helps us in knowing our students better. I happened to come across a poem written and posted by one of our students who we thought was good at science but his inclination towards creative expression was a surprise and was much appreciated by all. Also a connect with the school alumni keeps the warmth in student-teacher relationship alive.
