A Survey on Code Switching in your Lessons

[shamshoque]

Dear Colleagues,
We are currently working on a research project. We are trying to find out how much of your lesson-time ( 10%, 20%. 30%, 40%, 50% etc.) you spend in explaining the contents of your lessons in Bengali. What are the reasons that you have to use L1 (mother tongue) in your lessons?
Thank you for your sincere cooperation and honest opinion.
