Abstract
The increase in mobile communications has led to advanced educational methods and technologies through accepting new technologies. A lot of studies have tried to overcome temporal and spatial limits on using personal mobile devices and have tried to increase learning effectiveness using various efficient educational methods. In this paper, U-CLASS, an interactive learning management system that provides interactive communications between a professor and students, is proposed and implemented. Monitoring of academic achievement after a real experiment with the proposed system and analysis of educational activities during the experimental class are important points. In order to achieve that, the proposed system was used in a practical class at a university, and educational activities from the classroom were gathered and analyzed. The data on the educational activities include frequency of questions, attendance rate, and seat positions of the students. Analysis results show that the average distance between professor and student in the classroom is strongly related to the grade of the student. Students who have a higher attendance rate and who ask more questions commonly show higher achievement.
Highlights
In recent years, a lot of methods that use personal mobile communication devices and wireless Internet technology to overcome the constraints of time and space of a classroom have been produced
The U-CLASS middleware gets the information from students, merges it with other information in the database, and provides a variety of information to the professor in real time. This system supports a wide range of networks, such as code division multiple access (CDMA), third generation (3G), long term evolution (LTE), wireless fidelity (Wi-Fi), and local area network (LAN) [29, 30]
Where AD(x) is average distance between the professor and seat position of each student; x is a student who got a grade; Ri is the weighted factor according to the distance from professor, i = 1, 2, 3, 4, 5, 6; Ti is the number of students sitting in the same row; p is the total number of classes attended by a student
Summary
A lot of methods that use personal mobile communication devices and wireless Internet technology to overcome the constraints of time and space of a classroom have been produced. The system enables students to confirm their attendance automatically and answer multiple-choice questions from the professor by pressing buttons on the wireless Clicker node. This system has excellent performance and reliability, there are some problems in terms of cost and operation method, because it has to use an additional proprietary terminal unit. The proposed system is applied to a class environment, and data on educational activities that occurred in that environment are gathered and analyzed to determine the major factor promoting learning effectiveness.
