This paper discussed the concept of disability as it relates to classroom learning. The purpose of this paper is to show the uses of Assistive Device (AD) as an educational tool, and to highlight a few devices that can be used in the areas of Reading and Writing for science students with learning disabilities. Through the use of low-tech and high-tech devices, AD will be able to help students become better readers and writers. In the area of Reading, the use of AD will help students improve upon and build on their spelling abilities, and also better students’ decoding, listening, and oral skills. In the area of Writing, the use of AD will enable students to write neatly and legibly, to form letters correctly, and to write sentences that are grammatically correct. The paper conclude that If teachers plan carefully and use AD devices to enhance instruction throughout the school curriculum, Basic Science, reading and writing will not be the only subjects that students with LD will benefit. It was recommended that teachers need also to explore other avenues in their instructional curriculum where they can enhance learning through the use of AD.
