There are solutions for dealing with the problem of outside access. We can allot time in the school's library or technology lab for certain assignments, and we can direct students to the public library for long-term projects. If I end up in a classroom with little or no technology, there are ways around that. It sounds like there are various online sources for discounted computers and for refurbishing old computers. Grants are also possible in securing technological equipment, so all is not lost.
Students are going to need to be proficient at computers, for college and for the workforce. It would be a detriment to ALL students if we decided to forgo the use of computers in the classroom because SOME may not have outside access or a high degree of proficiency. We can alleviate the latter by giving extra time/help for students who may be foreign to computers. It will be imperative to help guide students in the direction of modernity, and technology is the way to do it. While I was initially resistant to the idea, I guess I need to get out of the dark ages, for my sake and the students' sakes.
As I mentioned, I will make time for students who aren't as comfortable with computers. Just as I would offer extra help to a child who was weak in reading skills or faltering in his writing abilities, I will give the extra resources for students who may be at a disadvantage technologically. It's only fair; we need to give them a level playing field.
