Benefits of Powerpoint with a Data Projector

This site details the benefits of using ppt with a data projector for literacy. The example on the site suggests that using a data projector with ppt reaches all students, regardless of the number of students in the class (as opposed to showing them a picture from a book, whereby, it is not a guarantee that all students will be able to see it).
New slides could be added, created the students, to supplement the lesson.
The site also includes some feedback from the students who received the ppt lesson using a data projector. Some feedback included the idea that words were easier to follow because they were bigger, having it on the computer was exciting because there were different sounds and graphics. Students Jay and Laura made a great comment in stating that it was great to see the pictures bigger and that the teacher didn't have to turn the book around so all students could see it.
There are some downfalls. One being that if pictures can't be scanned into the ppt, then the graphics shown will lose some of their visual appeal that would lend itself to getting the meaning and intent out of the pictures.
I think it's a great tool for the primary classroom. The teacher was quick to mention that it wouldn't replace their mandatory "read alouds", but using it could help to teach some expectations.
