What is up on the walls, is it warm and welcoming, is it crowded/distracting
The words/language that are said by the teacher and students
Standing by the door and welcoming everyone in
The teachers relationship with the students
Is there one?
Having relevance within the lessons
Building students up, using positive affirmations
Understanding and being able to communicate in their students language
Reading and writing it to communicate effectively
Organize class in a way that wont be foreign but familiar
