本研究透過六名教師執行八項工作任務與六名學生執行六項工作任務，受試者操作過程均透過Morae Recorder側錄軟體記錄受試者的操作歷程，另使用Morae Management軟體將側錄檔案轉換成數據資料，作為結果分析；另每一位受試者在完成任務後，須針對各項任務以主觀感受進行難易度之評分，並進行單一訪談以深入了解教師與學生在實際操作系統時所遭遇之困難與感受，進而對系統提出使用效能修正與建議。
Teachers can observed students’ learning status, and also can find their perplexing from the test system. It can be an indication to improve Teaching and Learning. When technology and internet integrate, there are many advantages on computer-based tests system, it is different to before. For example, it can test at anytime or it can depend on students’ level to use different assessment, and the result is immediately report from computer-analyzed, and this software can quickly handle a large number of answers ...etc. Therefore, computer-based test system deserves to be discussions and analyses because it has set and widely used in education, and the system operates whether users fit their requirements and cognitions to achieve maximum system performance.
According to literatures show that the usability of a system must allow users easy to finish their work and all of operation process should be satisfaction. Especially in computer-based test system that focused on setting different pattern for teachers and students in satisfaction because they have different necessary. To make this system is easy to learning and work, and be efficient system program. This study aimed to understand "computer-based tests system" of usability testing situation, a case study "A web-based examination system for junior high school students in taoyuan county ", use of usability testing, to summarize results and make recommendations. As achieved above purpose, in this paper star to explore the usability testing to its related documents, and understand the usability testing principles and evaluative methods for induce experimental methods and processes.
In the study, there were six teachers participating in eight tasks and six students took part in six tasks. All participators operate process to through Morae Recorder that is observation software to record all of courses for every participator. As well, there used Morae Management to convert the observation software into data information for result analysis. After finishing the task, every participator needs to give their feeling to score by all the tasks. Moreover, it can use an interview to understand about teachers and students of experiences which kind of difficult positions and feeling during their operating, and then revise and suggest this system.
The research discovery of the teacher’s management functions that "create student account" is the most difficult; the average score in operating is 4.33. Regarding with analysis, the system function was multifarious and professional, hence, it was difficult to general teachers. The test by students who "post a new topic in discussion area" is the most difficult to answer. The average score in operating is 3.67. Due to the system of function setting in “News” service, it has difference cognition by most of users, so that students were not easy to find this area for discussion.
As a result, it displays the whole system on usability testing should be revising system interface on bright and click on object can be clear and improve the font size、align…ect.
According to the result, this essay will supply some amendments, after this system evaluation. And also, this essay will provides some suggestions for following research. So the study hopes to people pay more attention and focus on this system of program features to advance the topic.
