Postmodernism represents skepticism toward metanarratives and universal ideologies that dominated the modernist era. The study focuses on three key postmodernist concepts - alternative assessment, process syllabi, and self-directed learning. Alternative assessment emphasizes evaluating the learning process over summative testing. Process syllabi focus on the learning experience rather than rigid outcomes. Self-directed learning enables student responsibility in setting learning goals and processes. This paper examined the effects of postmodernist educational concepts on improving Iranian EFL learners’ autonomy. A quasi-experimental pre-test/post-test design was utilized with 60 intermediate level Iranian EFL students divided into an experimental and control group (n=30 each). The experimental group received instruction utilizing the three postmodernist concepts over 14 weeks, while the control group received traditional modernist instruction. Autonomy was measured using a validated questionnaire before and after the intervention. The results showed the experimental group demonstrated significant increases in autonomy compared to the control group. Paired sample t-tests revealed significant differences between pre-test and post-test autonomy for the experimental group across all three postmodern concepts - alternative assessment, process syllabi, and self-directed learning. This suggests postmodernist concepts that decentralize instruction and emphasize student process over outcomes can enhance Iranian EFL learners’ self-direction and responsibility for language acquisition. The study implies EFL syllabus designers and instruction should transition to postmodern models centered on individualized assessment, flexible syllabi, and student-guided learning to boost autonomy. Further research can expand sample sizes and explore additional postmodernist concepts across diverse demographics.

Background : Work-related musculoskeletal disorder is the most important occupational disease that threatens the health of employees. Aim: The aim of this study was to investigate the relationship between workers' posture and musculoskeletal disorders. Materials and Methods: Eighty-two male and female workers working in a home appliance factory participated in this cross-sectional study. Musculoskeletal disorders were investigated using Nordic questionnaires. Posture evaluation was performed to measure the angles of forward head, rounded shoulders, and thoracic kyphosis using photogrammetry. Craniovertebral, shoulder, and thoracic kyphosis angles were photographed during the work and then measured using ImageJ software. Data analysis was done using SPSS 26 and Spearman's correlation test at a significance level of 0.05. Results : A significant relationship between the craniovertebral angle and musculoskeletal disorders in the last twelve months was observed in the cervical region ( P <0.001). Also, a significant relationship was observed between the kyphosis angle and musculoskeletal disorders in the last twelve months in the upper back and lower back ( P <0.001). Conclusion : The results showed that the workers’ posture during work is correlated with the prevalence of musculoskeletal disorders. Therefore, it is suggested to pay attention to ergonomic principles during work to maintain and improve the physical health of workers.
