The Effectiveness of a Manual Training Program in the Development of Mental Rotation Ability

Shadia Tal, Tahani Abu-wardih


This study aimed at investigating the effectiveness of a manual training program in the development of mental rotation ability, and for achieving that the cluster sample was chosen consisted of (80) subjects. Half of the subjects were males and the other were females, whose ages were (10) years of the 4th Grade from Al-hashimiah Basic School for Boys and Girls in Ajloun Educational Directorate. Two sections were selected randomly from each school. One of them consisted of an experimental group and the other consisted of a control group.
A manual training program was developed. The computerized pre and post mental rotation ability tests were also developed. Validity and reliability of the tests were achieved. The rotation ability was measured by reaction time (RT) of the correct answers and the number of the correct answers (accuracy).
Results of the study indicated that there were statistical significant differences in RT and in the accuracy between the experimental and control groups in favor of the experimental group where the RT decreased and the accuracy increased significantly.
Results also indicated that there was a significant difference in accuracy in the experimental group in favor of the females. Results also revealed a linear relationship between RT and the angular disparity. Results also showed the accuracy decreased with the increasing of the angular disparity.
