| Popis: | 100 With the aid of the computer technology, assessment evolves from the traditional paper exam to on-line test system. However, to engage learners constantly in learning, it requires strong motivation of learning and practicing. In the PC generation, learners can perform online learning at the fixed spots. It is difficult for learner to learn anytime anywhere with the limitation of the learning sites. It will decrease the learning motivation gradually and will be hard to recover the learning path. The item formats designed by the test system nowadays are usually not intuitive for most teachers. Most of them are too complicate or inflexible to fulfill the requirement of the teacher. Furthermore, with the preloaded content, most of the test systems cannot generate items automatically based on the content nor the learners learning progress. The study is to design the auto item generator based on the concept modules defined by teachers. The system uses syntax tools to help teachers to analysis the learning content and then define the concept modules. Once the concept modules are defined, the concept density algorithm is applied to select the appropriate concept to generate the test item automatically. In the meantime, the system will adjust the test flow based on the learners’ status and record the of learners’ progress. |
