Abstract: Mobile devices can deliver learning content and assessment “anywhere” and “anytime”, offering new opportunities for ubiquitous and personalized learning experiences. Despite the growing interest for mobile learning and mobile-based assessment, little research exists about the factors that influence students to adopt these new technologies. The current study applies the Technology Acceptance Model (TAM) to explain and predict the acceptance of mobile-based assessment in a European University. It proposes two additional variables, Personal Innovativeness and Previous Experience to the already known ones (Perceived Usefulness and Perceived Ease of Use) investigating how they influence Behavioral Intention to Use Mobile-Based Assessment. Partial Least Squares (PLS) was used for data analysis. Results indicate that Previous Experience and Personal Innovativeness have a significant influence on mobile-based assessment adoption.Practical implications are discussed.
