Students reflect their teachers. Students will perform differently for different teachers. Perhaps we should be more exacting of ourselves rather than of our students. Perhaps a visual presentation would have been more comprehendible than an oral presentation. An enthusiastic teacher will have enthusiastic students.
Diligent teachers produce diligent students.
Teachers with good attitudes produce students with good attitudes. As a student teacher, I taught and observed one class of students which received instruction from three different teachers. I was amazed to see how differently students functioned under each of the three teachers. One teacher was rather quiet and controlled, and so were the students under her instruction. Another teacher was loud and somewhat boisterous, as were the students when under her care.
