 goes back to my my underlying goal and that is to have students feel like they are capable of teaching themselves and teaching their peers about key concepts in the course. So what I've done with the concept maps is I've just actually isolated two out of the 12 learning modules in the course and the students completed a concept map for the not the first module in the course but their first concept map and they got used to using the technology which seemed to be a bit of a hurdle for them at first but by the time we used it for the second module of nutrients then they were more familiar with the technology and they tend to focus more on actual learning of the interrelationships between the nutrients.
