Service courses have different problems. There are diverse expectations between the statistics and other departments. There must be good communications between them with actual examples being used in the teaching. Many countries are experiencing either a growth in the number of students or a growth in the number of those with poor mathematics. There is the challenge of teaching the concepts without the mathematics.
Assessment plays a big role here as at the school level.
Students learn quickly what they are supposed to answer. If we are to develop our courses we must get feedback from our students. One way of getting feedback is to use minute papers at the end of the teaching session. Interaction between staff and student is important and needs to be developed. The lecture is not the best way of teaching.
