An intelligent classroom management system based on wireless sensor networks

Abstract

The learning efficiency in a traditional classroom is easily influenced by three factors: the learning environment, the instruction mode and the conditions of students. For improving the learning efficiency, an intelligent classroom management system with context-awareness based on the wireless sensor network technology is proposed and implemented in this research. The statuses of students and the classroom are detected by wireless sensors, and these statuses will be transferred to the management system built in a server. The management system will determine the current conditions of the students and the classroom, and give proper feedbacks to the students, the teachers, and the wireless sensor-controlled equipment deployed in the classroom. The proposed intelligent classroom management system includes three subsystems. 1) The environment management system regulates the classroom to a suitable condition for teaching and learning; 2) The instruction mode management system assists teachers to switch instruction modes quickly and smoothly to avoid wasting of time; 3) The learning behavior management system alerts students when they are inattention or fatigued. The proposed system is implemented in a classroom of Chung Hua University, Taiwan. A preliminary evaluation is also conducted to verify the correctness of the system.
