This research aimed at making a list of the reflective thinking skills suitable for students with hearing disabilities, and identifying the effectiveness of using visual thinking network (VTN) for developing hearing - impaired students' reflective thinking skills. A group of 33 hearing impaired students in the second grade at Al Amal, vocational preparatory school, for the Deaf and Hearing Impaired, Assiut Educational Administration, Assiut Governorate, Egypt. A theoretical framework was developed on the strategy of VTN, the skills of reflective thinking, the characteristics of the hearing disabled, and how to use the visual thinking networks in teaching mathematics for students with hearing disabilities. A set of tools and materials was also prepared, including: List of reflective thinking skills suitable for the second grade hearing -impaired students in the vocational preparatory stage, a booklet of activities and exercises, a teacher's guide, and a test in reflective thinking skills. By applying these tools and materials, using the appropriate statistical equations, the results of the research were reached: 1) The present research came up with a list of the reflective thinking skills suitable for hearing - impaired second grade students at the preparatory stage. 2) The effectiveness of using visual thinking network (VTN) for developing hearing - impaired students' reflective thinking skills. There was a statistically significant difference at the level of (0.01) between the average scores of the students on the reflective thinking skills test in the pre and post application in favor of the post application, and the value of the effect size using the equation of eta squared effect size in the reflective thinking skills was found (0.92), and in its sub-skills ranged from (0.61) to (0.86).
