Teachers need to have a certain level of comfort and skill with troubleshooting and supporting their students with technology.  Instructional time is valuable and it is much more efficient if the classroom teacher can quickly resolve basic issues instead of waiting for external support all the time.  However, it will certainly take time to build this capacity within teachers.  

When designing online instruction, it is certainly important for teachers to be very thoughtful in the organization of their content and delivery methods in order to accommodate the various learning styles of students and their experience with online learning.  I generally try to organize a course with the assumption that there is one person in my course with no experience with online learning or the Learning Management System.  In addition to this, online teachers need to consider how to support students who may need guidance with pacing their independent learning since it is very different than a face-to-face classroom. 

I think it is important to keep in mind the value of collaborative work even in an online setting.  It can take a little more effort in an online setting to ensure that everyone is comfortable with the setup, but I think it helps create a community of learners, deepen learning, and add interest to the learning environment.
