The purpose of study was to investigate the effect of teaching Physics using Needham's constructivist model in developing the critical thinking skills of tenth-grade students in Jordan. A critical thinking test consisting of (25) items, was applied over purposively sample consisting of (53) students in Mafraq, Jordan schools, randomly distributed into two groups: 1) as an experimental group which contains (27) students who were taught by the Needham's constructivist Model. 2) as a control group which contains (26) students. The results showed that there were statistically significant differences between the averages of the two groups in critical thinking skills as a whole in favor of the experimental group. The study recommended the use of Needham's constructivist model in teaching physics. (Published abstract)
