Children from low-income families may face the following challenges of literacy and prejudice when using e-learning tools: 1. **Inadequate digital literacy**: Many children from low-income families may lack the necessary digital literacy to effectively use e-learning tools. This may include familiarity with basic operations, information screening skills, and online safety awareness. 2. **Unbalanced access to resources**: Low-income families often have difficulty accessing high-quality e-learning resources and tools, and may lack stable Internet connections or appropriate electronic devices, which puts them at a disadvantage when using these tools. 3. **Inadequate family support**: Due to their parents' educational background and financial pressures, children from low-income families may lack learning support from their families, and parents may not be able to provide the necessary guidance or supervision, affecting their children's learning outcomes. 4. **Social prejudice and low expectations**: Children from low-income families may encounter prejudice from their peers or teachers, who believe that they have low learning abilities. This cultural prejudice may affect their self-confidence and motivation to learn. 5. **Mental health issues**: Financial pressures and unstable living environments may cause children to face mental health issues such as anxiety and depression, which in turn affects their learning outcomes and the use of e-learning tools. 6. **Unequal learning opportunities**: Children from low-income families may not fully utilize the learning opportunities provided by e-learning tools for a variety of reasons (such as lack of extracurricular activities, insufficient stimulating learning environment, etc.), resulting in lagging knowledge and skills development. 7. **Cultural Deficiency and Adaptability Issues**: The content and design of e-learning tools may not fully take into account the cultural background and life experience of children from low-income families, resulting in insufficient empathy when learning, leading to resistance to learning and adaptability issues. In summary, the challenges of literacy and prejudice faced by children from low-income families when using e-learning tools are very complex. Solving these problems requires the joint efforts of families, schools and society to provide more equitable and comprehensive educational support.
