The relationship between teaching and research is often assumed and just as often ignored. Research should and does influence the teaching (and vice versa), but the gap between the two can at times seem large. Many of us are talking about very narrow connection between research and teaching. These voices are too often heard from colleges. But many academicians have got naive ideas about the work of a teacher; their ideas are often too far from the reality. The academicians often hold the concepts about an ideal class, where all the pupils are engaged in the teaching content; they do not consider the discipline sustaining.
