Julio,
Yes, sticking with what works for you is key. When technology becomes a hindrance rather than an effective tool for both you and your students, it defeats the purpose. Hopefully after completing this course you will feel comfortable incorporating technologies that work well with the tools you have already incorporated into your curriculum, such as Google docs for online sharing and review, or Zoho, for collaborative learning projects.
Wishing you continued success in the classroom.
