[/qb][/QUOTE]The problem is that many in my lectures do talk on the phone during lectures (even my smaller discussion seminars of 10 people or less) or the text message during class as if they have nothing else better to do. [/QB][/QUOTE]

It was the same for me, but people were politer and went outside to answer the phone, so the lecturers didn't mind. And back in high school, this was 4 years ago so phones weren't as 'popular' then, they weren't allowed in the school at all.
