he aim of the current research is to prepare a unit in science based on technology learning centers and to investigate its effectiveness in developing certain visual thinking skills among 8 hearing-impaired students who will be heading in the intermediate school. The researcher used the one-group quasi-experimental design in which both groups were pretested and posttested. The proposed unit " Alam al-Hayawan (Animal World)" was taught using technology learning centers. There was a statistically significant difference at the 0.01 level between the mean scores of hearing-impaired students in the first year intermediate in favor of the post-administration.
