Curriculum is dynamic and changes over time due to various factors such as new information, technology changes, research findings, and shifting societal attitudes. Modern trends in curriculum development include incorporating new educational technologies, preparing students for an increasingly globalized world, emphasizing continuing education and interdisciplinary knowledge, and focusing on vocational and skill-based learning. Issues facing curriculum development in Pakistan involve teacher reluctance to change, insufficient teacher training, political interference, economic problems, inadequate evaluation systems, weak adherence to national education policies, societal disapproval, urban-focused curricula, and a lack of teaching resources in schools.
