Ramkumar Rajendran,a research scholar at Monash Research Academy of IIT Bombay,is currently researching on the development of a mathematical model for intelligent tutoring systems,which could predict and address in real-time the emotions of students,such as frustration,while they interact with the system. The primary aim of the research,according to the academy,is to develop a model that predicts the affective states of users like confusion,boredom,excitement and frustration,among others,and address them,so that the process of learning and teaching is more effective.
The system will adapt the learning content based on student performance,background and previous knowledge. Some of the teaching tools are designed to provide personalised learning content based on the students needs and preferences.
The benefit of such a system is that students,who like to learn at their own pace with computer-based self-learning methods,will not drop out because of boredom or frustration,since they are constantly engaged by content adapted by the system,based on their affective state, Rajendran said.
The model being developed by him is based on information available in the log file of Mindspark,a math intelligent tutoring system.
The work has been tested only on students in the age group of 10-12 and cannot be generalised to all age groups. We constructed a basic model and our research is in its nascent stages of real-time emotion identification, he said.
According to experts,the methods that have been implemented so far in the intelligent tutoring system to predict the affective state include human observation,self-reported data of learners of their affective state,analysing data from physical sensors,face-based emotion recognition systems,mining the systems log data and assessing the data from physiological sensors like galvanic skin response and ECG,among others.
Academicians,however,said with the exception of data-mining approaches,the other methods were at present not feasible in a large scale real-world scenario to predict affective states.
