Peacelessness Masjid of my school

There's nothing that I can do to prevent them happen but hope Allah willing to help me... Months have passed. Whenever it's time for solat, the students was just so slow to move for wudhuk. Me, myself with other school authority have to sound them like have to kick a ball for a goal. That's just at the outside of the Masjid but what's worst is in it. 20% of the students would respectly make saf as else making a group or circle for chattering automaticly make it noisy. I'm very disappointed. Why do they need authorities to push them ? As Islam itself told them to. Aren't they have no Iman ? Aren't they fear Allah ? They thought I'm fear them but they're wrong. What would I need to fear them as there's the one that I feared and will help me as long as I pray to Him. Hope Allah willing to help to restore the Masjid's condition.
