 They asked the students to complete the very first concept map. And then we had a class that was dedicated to going through any issues they had with learning the material and using the technology. And what came out of that is that they would have liked to have had some guiding questions, basically resources to support them through using the technology before they launched into using it. So for the second concept map, I did provide a lot more guiding questions ahead of the students completing the concept map, whereas they came after the students had completed the concept map for their first module of nutrients. So yes, there were some challenges, but again it's a learning curve for everybody. And overall, I think the class and I came together more as a team as a result of using the technology.
