Abstract D Due to the rapid developments of technology and its effects on learning English for Specific Purposes (ESP), the study aimed at applying ProWritingAid (PWA) and BASDELL model to improve business English writing skills and reduce writing anxiety of management sciences students. Participants were randomly assigned into two groups: experimental (N=30) and control (N=30). The experiment lasted eight weeks at a rate of two sessions per week in the second term of the academic year 2022/2023. Instruments, designed by the researcher, were: A Checklist of Business English Writing Skills (CBEWS), A Test of Business English Writing Skills (TBEWS), a rubric to score it and A Writing Anxiety Scale (WAS). The pre/post-test experimental and control group design was adopted. Results showed that ProWritingAid and BASDELL model improved business English writing skills and reduced writing anxiety as the scores of experimental group students' business English writing skills were higher than those of the control group students. Findings provided insights into the inverse correlation between writing skills and anxiety.
