Technology is also useful in that it can provide a variety of accommodations for students with different learning needs. For example, if students have difficulty seeing, screen size and print can be enlarged for ease in reading. There are programs available online or for the desktop, which can translate text to other languages or even read it aloud to students as they follow along silently. In addition, many programs and activities are interactive and allow students to manipulate objects while exploring new concepts in subjects such as math and science.
