This systematic review examines the application of poststructuralist theories in the development of diverse curricula, focusing on their impact, benefits, and challenges. Poststructuralism, with its emphasis on the fluidity of meaning, critique of power structures, and the dynamic interplay between knowledge and society, has become increasingly influential in educational theory and curriculum design. The review begins by exploring the foundational concepts of poststructuralist theories, highlighting the contributions of key theorists like Michel Foucault and Jacques Derrida. It then analyzes various case studies where poststructuralist principles have been successfully integrated into curricula, particularly in higher education and elementary schools. The findings indicate that curricula informed by poststructuralism foster critical thinking, creativity, and active student participation, making them more adaptable to contemporary societal needs. However, the implementation of such curricula also faces significant challenges, including resistance from traditional educational structures and the complexity of poststructuralist ideas. The review concludes with recommendations for future research and practical strategies for curriculum developers to effectively integrate poststructuralist theories into educational frameworks.
