As teachers face increasing demands to meet the needs of students with special needs in inclusive classrooms, there is a corresponding increase in the need for professional development opportunities for practicing teachers in areas that will assist them to become more knowledgeable in meeting these needs. One area of concern for teachers is the use of assistive technology tools in the classroom with students with special needs. Teachers frequently report a lack of skills and knowledge in the area of providing support for the use of assistive technology tools in the classroom, largely as a result of inadequate preservice training (Chmiliar, this issue). Opportunities for teachers to engage in accessible professional development in the area of assistive technology are important. Athabasca University has developed a unique online course in assistive technology to meet these professional development needs. This paper will discuss the survey that led to the development of this course in assistive technology, as well as the development and implementation of the innovative online features of the course.
