Large class sizes, lack of basic infrastructure like clean water and toilets, and inadequate learning materials can negatively impact the quality of the learning environment. However, the quality of school facilities alone may not determine student achievement - other factors like early childhood experiences, health, nutrition, parental support, and quality teaching methods also greatly influence learning outcomes. Creating positive early learning opportunities, ensuring basic health and nutrition needs are met, improving parental and community involvement in schools, and adopting student-centered teaching practices can help children succeed, even in challenging physical learning environments.
