Mathematics preparation and professional development of deaf education teachers.

With the world increasingly dependent on mathematics and problem-solving skills, the poor mathematics performance of deaf and hard of hearing students is cause for concern. The present article focuses on the mathematics competency of teachers of deaf and hard of hearing students as a factor in this poor performance. As part of a larger study (Pagliaro, 1996, 1998a), deaf education teachers provided data on their postsecondary education and their professional development activities related to mathematics. Administrators were also questioned to investigate the schools' contribution to these activities. Results reveal an insufficient level of mathematics preparation among deaf education teachers, especially at the high school level. Few hold degrees in a mathematics-related field, and only a moderate number seek professional development in this discipline. Recommendations for improving the mathematics competencies of deaf education teachers are provided, with the objective of improving student performance.
