Mobile based assessment (MBA) specifically in the context of mobile learning is still in its infancy. Many previous studies had addressed the influencing factors of user acceptance and intention to use MBA. In order to adopt MBA in an educational environment, the influencing factors to student intention need to be investigated. Hence, this current study attempts to determine the impact of the factors related to internal assessment environment on the tertiarylevel students' intent to use MBA from the standpoint of the motivation factors. A total of 90 mathematics and computer science undergraduates participated in a survey on the adoption of MBA after a real experiment of mobile based assessment. Data analysis used the structural equation modeling (SEM). The findings reveal that the students' intention to adopt MBA can be predicted and explained by several key motivational drivers i.e. Usefulness, Ease of Use and Enjoyment. Based on the findings, motivation to learn, educational assessment content, and the navigation system design of MBAs can be enhanced by satisfying the three aforementioned motivational factors.

Despite many studies being conducted on mobile learning acceptance, few investigate mobile-based assessment acceptance. The objectives of this research are to provide valuable insights into current research on mobile-based assessment literature, and to identify the main gaps in the mobile-based assessment acceptance literature. Therefore, the present study systematically reviews 48 previous studies and eight articles related to mobile-based assessment acceptance to provide a comprehensive analysis of the articles published from 2009 to 2019. Findings indicate that majority of mobile-based assessment studies focused on evaluating the effectiveness and performance of mobile-based assessment system and conducted at the secondary school level. In addition, this study identified several gaps. Further research is needed to study the acceptance problem of a mobile-based assessment system. More investigation is required to predict which external factors that can enhance the acceptance and use of mobile-based assessment among students. The findings of this review study provide a valuable reference for researchers about the current trend of mobile-based assessment research as well as the research gaps that should be covered in future studies.
