I agree that the classroom can greatly improve the learning experience for the student but in many situations the teacher/instructor has no ability to modify this area.I work in a technical training school where my input or feedback is not even considered.I would love to change things up but,some of the factors that prevent me changing the classroom are:I teach a subject for only three week intervals.The next three weeks I may be teaching a completely different subject in a different room to a different group of students.During the three weeks I am teaching,two other instructors are teaching the same subject in the same room at different time frames(teaching styles and students learning styles coming into play).No budget available for modification from original room set-up.No modification allowed without going through an extensive approval process.Not much advance notice of the subject I am teaching or where I am teaching(usually two days or less).No classroom downtime to make any changes between three week rotation periods.I am asking for any suggestions that I can implement in my classrooms,considering the restrictions I previously mentioned.
