Bad modelling teaching practices

There are numerous excellent textbooks that provide guidance on what and how to teach modelling, founded on sound principles (e.g., mathematics, domain analysis, object-orientation) and engineering practice. There is less guidance available on what and how not to teach modelling - i.e., what principles to avoid conveying either directly or indirectly, and what engineering practices should be ignored (e.g., because they misrepresent the practices of modelling). We describe a number of bad modelling teaching practices that we have identified, as a result of substantial individual and team teaching experience to both industry and academia.
