Immersive learning is one of the leading trends in education. Immersive learning uses a simulated or artificial environment for a better learning experience. Design of intelligent learning platform and motivating content development is one key aspect of immersive learning. In this article, we propose an intelligent computer-assisted learning platform that helps school-level students in self-learning. Specifically, the proposed platform focuses on biology learning. The learning platform performs several tasks including automatic identification of important terms and concepts, identification of questionable sentences, visualization of key concepts through relevant images, and conducting a mock test for confidence building. Various techniques have been adopted for the development of the individual functionalities. Working of the individual modules is evaluated by two human experts. In addition, in an individual-level learning setup, the platform is used by 50 Class IX students for studying a module. They provided feedback on the system through a questionnaire. Both the human expert-based and questionnaire-based evaluation results demonstrate that the platform offers satisfactory performance.
