Here’s how I would answer this – the focus first and foremost is on the educational outcomes of the lesson. When technology can help me with those outcomes, I would incorporate it into the lesson.  

Technology can:

Reinforce a concept

Present a concept in a different way

Engage students

Allow students to be creative in a way that might not possible without the technology

Transform the way you are currently teaching a topic

How this will practically work at the school you’re applying for might depend on the technology available at that school. For instance, if you have access to devices for each student you can take a different approach to the use of technology, compared to only having a single computer or tablet.  

You could also point out that that even if you have a single device there are some great things you can do. If you’re stuck for ideas for single devices, take a look at my 15 Ways To Use Just One Computer In The Music Classroom article and my 18 Ways To Use A Single iPad In The Music Classroom article.
