Alan Buchanan, who taught in Rosshall Academy in Crookston, was given a two-year teaching ban by the General Teaching Council (GTC) Scotland.

The former maths teacher was first summoned before the GTC in August but failed to appear for the hearing.

Yesterday education bosses heard how his classroom was "chaotic" and moved to strike him from the teaching register. Again, Mr Buchanan failed to appear in front of the panel.

He was criticised for failing to create lesson plans, failing to communicate properly with his pupils and setting work that was too easy, leaving youngsters "demotivated and unenthusiastic".

Mr Buchanan did not set homework for his pupils and his classes' attainment was poor compared with others in the school.

The teacher also allowed youngsters to shout out in class or wander around the classroom, resulting in an "unsafe and disorderly atmosphere".

He let a group of boys use "highly inappropriate sexual language" towards girls in the class without disciplining them.

One pupil ripped tiles from the classroom ceiling and another hurled a blind across the room while the teacher failed to intervene.

Mr Buchanan, from Rutherglen, was first employed at the school on a job-share basis in 2003. Despite concerns over his attendance, he was given a full-time, permanent position in 2008.

Representatives for the South Side school said Mr Buchanan was given "unprecedented levels of support" from school management but he failed to improve.

All the charges are said to have occurred between November 2008 and May 2010.

A Glasgow City Council spokeswoman said: "This teacher was dismissed by the council in May 2010 due to chronic incompetence."

At the end of the two-year ban, Mr Buchanan will be entitled to reapply to be added to the teaching register.
