When should technology be used as a learning tool?

With Technology

• Cross-cultural/international collaboration
• Simulations of scientific phenomena
• Connecting to current culture (social media)

Without Technology

• Hands-on activities (learning by doing)
• Labs
• Particularly those that are inquiry-based - technology encourages one to search for the "correct" answers immediately
• Theatre/Dance/Music performances and activities
• Field Trips
• P.E.

I've put very few items in each category because I have a hard time saying "X should never be done with technology" (or vice versa).  I think most things can be done well either with or without technology, with a few exceptions (the items I have posted above).  However, there are even exceptions within the items I chose to post.  

For example, cross-cultural/international collaboration usually lends itself to technology use because without technology it wouldn't be possible.  However, if it were possible to do it without technology, perhaps with a cross-cultural group within the school, this could be even more beneficial.  Similarly, the hands-on activities are best without technology the majority of the time.  However, some labs need technology tools (or even simulations) in order to be most effective, along with hands-on learning.  

I think what it comes down to is not a black and white statement of "this should be done with technology and this should not."  It is important to think consciously and not using technology blindly, but instead considering its impact on the lesson.  

For example, improv is a situation that at first I would say should never be taught with technology.  If a teacher wants to teach improv to a group of students, an online tutorial about improv would not be very useful.  However, technology could be used to show students successful improv groups around the country or the students could use technology themselves to create their own filmed skits.

Technology should be used to achieve the learning objective.  If the learning objective is clear and this is the case, technology will support and not hinder learning.
