The current study aimed at developing Al-Azhar model primary institute pupils’ EFL creative writing via activities based on the cognitive learning-centered approach. The experimental design was adopted in the study. Forty EFL pupils enrolled in the sixth year of Al-Safwa Model Primary Institute in Zagazig, Egypt during the first semester of the academic year 2023/2024 were selected to be the participants of the study. They were specified equally into two groups: experimental and control. The experimental group was taught using activities based on the cognitive learning-centered approach, whereas the control one received regular instruction. Data were collected through the EFL Creative Writing Test designed by the researcher. These instruments were pre-and post-administered to both groups. The results revealed that a) the experimental group pupils outperformed the control group ones in the post-administrations of both the EFL Creative Writing Test, b) the experimental group did significantly better in the post-administrations of the EFL Creative Writing Test than in the pre-administrations, and c) the effect size of utilizing activities based on the approach was found to be high and positive. Consequently, it is recommended to use activities based on the cognitive learning-centered approach to promote EFL creative writing of EFL learners.
