| Summary: | 碩士 === 國立交通大學 === 資訊學院資訊學程 === 101 === With the advances in information retrieval technology and widely used in learning fields, in addition to quickly obtaining a variety of new knwoledge and explanations, the better to achieve ubiquitous learning environment, it has been reported by researchers in the language learning applications, through stand-alone software query, and gradually evolved into a network query patterns. However, it is relatively inconvenience on mobile devices while using the traditional way by the keypad to enter a query with the mobile devices. The users must remember correct wording of idioms in order to successfully carry out inquiries in traditional text idiom search system. Although some studies propose associative search techniques, it may sometimes limited to the difficultly to use appropriate words to express the situation. Therefore, this study intends to make idiom search system of using visual scenario as input. By using graphical user interface, through pictures and story editor as the search key to proceed idiom search for providing a more intuitive, more natural input methods, to solve the idiom search difficulties.
Using the benefit of graphical dragging, pulling, setting free easily, inputting visual components idiom search, allowing users to easily use mobile phones and tablet computers and other kinds of portable handheld devices in operation to solve learning idioms flaws on mobile ones. Not only using simple image search function, but also allowing users to use ways of dragging and dropping graphics to proceed the editor of scenario and scenario of editor automatically for being converted into searchable keywords. Through the operation of scenario editing will help the students learn about the mood and meaning of idioms, assist and enhance students' understanding and memory for idioms, using theoretical characteristics by learning in progress.
The study also designed related experiments of learning achievement, cognitive load and software usability for future investigation. The results showed that the learning achievement of using visual scenario search system for elementary school students on idiom self-learning is the same as the traditional text search one. In the analysis of cognitive load, we found it can help alleviate the pressure of students' learning through idiom search system of visual scenario, and can help memorize idiom for them well. In the user's software usability evaluation whose results show such positive feedbacks as using more conveniently, using more often willingly and reading more easily for interface design.
