Denise,
You are expressing the experience of many. For you to continue to model the different (more productive) way to look at the information is one of the best strtegies. Modeling the correct process in scenario-based learning gives the student a strong contextual understanding at the (Bloom's) application level. Discussing it in the abstract sometimes does not give the student the ability to apply the information appropriately (depending on the learner). Excellent approach - thanks for sharing.
