According to research by Johnson and Brown (2020), the shortage of adequate teaching materials significantly affects students coming from low-income families. Schools with limited budgets often cannot provide the necessary resources, which ultimately widens the educational gap and increases inequalities in learning outcomes.
Additionally, Sharma (2019) emphasizes that the absence of engaging and diverse teaching tools leads to a decrease in students' interest. Without interactive or visual content, lessons tend to become repetitive and boring, which lowers students' motivation to actively participate in class.
In essence, students from poorer backgrounds face greater challenges because their schools lack enough resources, and when lessons are unengaging, their enthusiasm for learning diminishes, deepening inequality in education.
