Moreover, all students with special needs must have their own educational program called individualized education program (IEP) (Woolfolk, Winne, & Perry, 2012). Students are evaluated if any assistive technology needed to be used in the classroom before they are allowed to purchase assistive technology through their IEP. Therefore, as we can see, assistive technology plays a big role in the individualized education program of each student. There are a number of programs that can be used in classroom teaching to support students with ADHD, students with hearing impairment, and students who are blind. For example, a math or spelling program that contains all kinds of interesting images and sounds can capture the attention of students with ADHD. For students with hearing impairments, there are some interactive videodisc programs that they can use to learn sign language. And there are other devices that convert printed materials into Braille for students who are blind (Woolfolk, Winne, & Perry, 2012). .
Moreover, students with physical disabilities also need extra help in classroom learning. Their movement is limited by the impairment of their body parts; therefore, they might experience difficulty in activities that involve using fine motor skills such as turning book pages and controlling computers. "Technology can be a powerful equalizer for people with disabilities, allowing them to get around a limitation in any number of areas " (Believe Ability Inc., 2008). There is a useful assistive technology for students with physical disability introduced by a company, Natural Point, called SmartNav4 (NaturalPoint, Inc., 2011). According to NaturalPoint (2011), the SmartNav 4 is an assistive technology which is introduced to students with "ALS, spinal cord injuries, muscular dystrophy, and other special needs " to use in the classroom. The SmartNav 4 is "a total hands-free mouse solution " that can be available for students who have severe physical disabilities and cannot use their hands to control keyboard and mouse.
