The study aimed to reveal the effectiveness of using Needham's constructivist model in teaching technology to develop productive thinking skills and technological awareness among middle school students in Palestine. The study followed the semi-experimental approach. To achieve these goals, two study tools were prepared: a test of productive thinking skills and a scale of technological awareness. The sample consisted of (90) female students, (45) in the experimental group and (45) in the control group. The study tools were applied before and after the intervention. The results indicated that there is a statistically significant difference (p ≤ 0.05) in favor of the experimental group in the post-application of both the productive thinking skills test and the technological awareness scale. The study recommended the use of Needham’s constructivist model in teaching technological topics due to its effectiveness.
