With a modern, robust new curriculum carefully prepared by local and international experts to meet the needs of Uzbekistan’s students, how would the Ministry of Preschool and School Education (MoPSE) ensure the effectiveness of textbooks and teacher guides in the classroom? The new teaching and learning materials (TLMs) created and customized by the USAID-funded Uzbekistan Education for Excellence Program in partnership with the MoPSE were developed through a multi-step, participatory process. Input from international experts and Uzbekistan primary teachers and academics grounded the modern methods and practices in the local context. To evaluate the use and value of these TLMs for students and educators, the Program led an extensive pilot initiative.
