I found these chapters very interesting and informative because they propose ways of using word processing in the classroom that are very different from my own experience in elementary school. In fourth grade, I did the Mavis Beacon typing class, but other than that, my only memory of using word processing was to type up pre-written reports at home. Word processing was not regularly used the classroom.
In these chapters, however, the author presents many ways to integrate word processing into the regular language arts, math, and social studies curricula, which I think is very useful. I especially like the Virtual Email activity on page 97. When I was in elementary school, we did a similar activity in which we wrote letters to historical figures. That was a very useful activity because we not only researched the historical figure and displayed our knowledge, but also practiced social activism by writing the letters and were able to hone the real life skill of letter writing in the process. I think it is fantastic that this exercise is given a tech-savvy makeover in this chapter. The children in classrooms today will most likely write more emails than letters in their adult lives, so practicing email conventions is extremely important.
I also appreciate the point the author makes about children being able to edit and embellish more easily when using word processing. Even as a college student, that is very important to me. I always type my assignments rather than handwriting them because it is easier for me to get my thoughts down then rearrange them, explain them, and correct them using a computer. I think that teaching students that skill at an earlier age will definitely be to their advantage.
