Abstract
The presented paper examines the students’ adoption of the use of a cost-effective biofeedback system for anxiety awareness in parallel to examination activities. Human anxiety is classified by evaluating bio-signals related to skin conductance, skin temperature and heart rate. The participants of the research were 44 students who were taking examinations in the form of synchronous online tests in the classroom for one of their courses. At first, the usability of the biofeedback system was examined using the system usability scale (SUS). The statistical analysis indicated that the examined system usability is quite satisfactory. Then, the study attempted to investigate the relationships between the students’ technology readiness personality dimensions, perceptions of usability, and the usefulness of the presented system by exploiting the technology readiness and acceptance model (TRAM). The results showed that the students’ optimism and attitude towards using the system are significant factors that affect the model’s relationships. The examined relationships are presented via a path model.
Highlights
We initially examined the factor structure of the Greek version of the eight questionnaires that measure the variables included in the model based on Technology Readiness and Acceptance Model (TRAM)
Optimism questionnaire: The one-factor structure of the questionnaire based on 9 items was not verified by the initial confirmatory factor analysis (CFA)
A second CFA was performed, using a revised item set for the questionnaire
Summary
It is commonly accepted that user experience is a crucial factor that determines the intensity of use of a product, and that if a product creates negative experiences, users will not like it and will use it half-heartedly. During challenging educational activities, students concentrate their attention on the activity at hand and do not feel very enthusiastic about using biometric equipment or, even worse, biofeedback techniques in parallel to their main activity. They usually feel that all these collateral activities divert their attention and inhibit their efforts to achieve a better performance. Products that manage to create a positive user attitude can most probably overcome many potential obstacles, presenting a certain advantage
