Sir,
REVIEW OF THE CONDUCT OF TEACHERS AND STUDENTS
As a concerned student of Universal Model School, i thought it wise to write to you regarding the conduct of teachers and students.
Many students of Universal Model School have ceased to dress in the correct and complete school uniform. Many students come to school these days without a tie or a badge as required. This projects the school in bad light to the outside world.
Secondly, students have developed a lackadaisical attitude towards homework and projects. This is more common among the senior students. This makes it difficult for the teacher to really assess the understanding of a student after a lesson. This trend needs to be strongly discouraged.
Many teachers are now more punctual to class. Some teachers arrive the class very early ahead of the time scheduled for their lesson. This has made it possible for such teachers to cover the syllabus for the term in their respective subjects. This is highly commendable!
Also, some teachers now use multimedia tools in lesson presentation. This helps to engage our mind during lessons so that we get more out of the lesson. This should also be encouraged.
I hope that concrete actions taken in the direction of the issues raised in this letter will move Universal Model School to greater heights.
Yours Faithfully,
Jude Njoku
