Usability Issues of Web-Based Assessment System for K-12 and Implementation of PAS System

Web-Based Assessment (WBA) System for K-12 needs to support the educational assessment according to the process-oriented learning and instruction. Usability issues of the Web-Based Assessment (WBA) System for K-12 refer to how to make questions efficiently, and how to control the access to the final Html test files from unauthorized people. In this paper, we study the usability issues of the antecedent WBA system and additional attributes based on PBA model (offline paper-based assessment); changing the current test class, applying Html access key value, and using student’s school identification such as individual name, class, an examinee's number for logging into the WBA system. Finally, we design and implement web-based online evaluation system, called PAS (PBA-based Assessment System), according to the usability issues discussed in this study. As a result, an instructor can make assessments more frequently and conveniently. Key-Words: Examinations and Tests via Internet, Web-Based Assessment System, Usability and Accessibility
