Abstract
An online questionnaire was used to investigate how linear programming is taught across disciplines countries. The questionnaire was sent to 311 lecturers in Australia, New Zealand, UK and USA. Lecturers also completed an "approaches to teaching" questionnaire and some of their students completed an "approaches to studying" inventory. The study found that mathematically intensive topics such as interior-point method and revised simplex method were taught primarily in USA. Also, lecturers in "pure" disciplines such as mathematics tended to use less software than lecturers in more applied disciplines but taught more solution methods. The sensitivity analysis topic featured more strongly in applied disciplines such as business and engineering. Whilst there appeared to be no differences in "approaches to teaching" between the disciplines, students in the "soft" disciplines such as business appeared to have a more strategic approach than students in the "hard" disciplines such as mathematics and engineering. The study suggests using qualitative methods for further research to collect richer data.
