Barriers to Infusing Technology

I find incorporating technology into my class can be very difficult.  One of the biggest obstacles I face is the lack of relevant materials.  It is difficult to find applications that have the ability to enhance the learning.  Many are below grade level content and/or are lower on the blooms chart, as in practice.  My second barrier is time.  Time to build the lesson, time to setup student accounts, time to instruct them on how to use the technology, and often time wasted because the technology is not working like it should.  Another barrier that I struggle with is students inability to type equations or show their work.  In the past students get frustrated and request paper and pencil.  Finally I have found that my students do not have their technology with them.  Even if I remind them for a week, they will forget to bring it or it will be broken.
