However, several challenges need to be addressed to improve the effectiveness and scalability of these systems. These challenges span across various aspects such as data quality, system scalability, integration of multimodal data, and user interaction.
• Data Quality and Availability:
      One of the primary challenges faced by domain knowledge-based interactive learning systems is the quality and availability of domain-specific data. High-quality, well-annotated data is crucial for training machine learning (ML) models that power these systems. However, obtaining sufficient amounts of data, especially in niche or specialized domains, can be difficult and costly. Additionally, data must be curated and cleaned, which is a time-consuming process. The lack of access to diverse data sources can lead to inaccurate or incomplete learning models, limiting the effectiveness of the system.
• Scalability and Generalization:
      As domain knowledge-based interactive learning systems scale up to serve a larger number of users or more complex learning environments, they often face challenges related to scalability and generalization. A system that works well in a small-scale pilot may struggle to accommodate diverse learning needs across larger datasets or domains. The system must also be capable of adapting to the varying levels of expertise, learning styles, and educational backgrounds of users.
• Integration of Multimodal Data:
      Domain knowledge-based systems often require integrating data from multiple sources or modalities, such as text, audio, images, and video. Effective fusion of this multimodal data is a significant challenge. Different types of data require unique processing methods, and ensuring that they complement each other can be difficult. Improper data fusion may lead to inaccurate predictions or irrelevant learning recommendations.
• Personalization and Adaptivity:
      Personalization is crucial in interactive learning, as each learner has unique needs, preferences, and prior knowledge. A one-size-fits-all approach can lead to disengagement and suboptimal learning outcomes. The challenge lies in creating a system that can continuously adapt to a learner’s progress, learning style, and specific needs. The personalization process needs to be dynamic, ensuring that learning paths are tailored in real-time based on user feedback and performance.
• Ethical Considerations and Bias:
      Another significant challenge is ensuring that domain knowledge-based interactive learning systems operate ethically and fairly. Machine learning models can inherit biases present in training data, leading to biased outcomes that disadvantage certain groups of users. Furthermore, privacy concerns arise, especially when personal data is used to tailor learning experiences. Users must feel confident that their data is handled securely and ethically.
• User Acceptance and Trust:
      For domain knowledge-based interactive learning systems to be effective, they must gain the trust of their users. Some users may be skeptical of machine learning models and algorithms, especially when decisions or recommendations are made without transparent explanations. Users are more likely to engage with a system that they trust and understand.
• Real-time Feedback and Decision Making:
      In interactive learning, providing real-time feedback that is accurate and contextually relevant is a significant challenge. Learning systems must process large amounts of data quickly and make decisions that directly influence the learner’s progress. Delay or inaccurate feedback can frustrate users and impede the learning process.
• Interdisciplinary Collaboration:
      Building domain knowledge-based interactive learning systems often requires collaboration between domain experts, educators, and data scientists. Without interdisciplinary collaboration, systems may lack sufficient depth in the specific domain or fail to address key pedagogical challenges. Effective communication between these groups is vital for creating systems that are both educationally effective and technically robust.
