ABSTRACT
It is a novel idea of this research project to design and develop the Thai Sign Language-Computer Assisted Instruction Authoring Tool, called TSL-CAI Authoring Tool. This tool will be used to support the instruction and learning of Thai Sign Language (TSL) for Thai deaf and impaired-hearing persons. The design of the TSL-CAI Authoring Tool is based on the model of the IEEE 1484 CAI Architecture Standard of Learning Technology System Architecture (LTSA) and the Instructional System Design Model of Dick and Carey, which is used as a controlling model to design a better instructional system environment. This authoring tool was used to develop the Thai Sign Language CAI lessons and also served as a learning environment for Thai deaf and impaired-hearing persons. TSL instructor can use the TSL-CAI Authoring Tool to develop the Thai Sign Language Knowledge Library consisting of a Thai Sign Language Dictionary, Thai Sign Language Lessons, and Thai Sign Language knowledge Evaluation tools. Furthermore, the TSL-CAI Authoring Tool provides a feature to add video image stream of moving Sign Language and has a hyperlink to the Thai words in the dictionary using the Longest Word Matching Segmentation technique. Instructors will have more freedom to design and develop their own lessons and evaluation. This prototype was developed on the Windows environment using Microsoft Visual Basic 5.0 Service Pack 3. It is an interactive hypermedia application with the user. The system consists of 18 forms to support the information in many media types, to create hyperlinks of TSL words in each lesson, and to present the information of the TSL-CAI Authoring Tool. The number of lines of the application program is more than 7,000 lines. The data storage of test samples requires more than 500 MB. From the experiment of all functions of the system, the response time is acceptable. A prototype that provides the functions of the Authoring tool to support TSL instructors was also successfully developed. The experiment shows the success of developing the TSL Knowledge Library and TSL-CAI lesson. In addition, the learning environment was also tested. The result demonstrated the 4’I characteristics of a standard CAI, namely, Information, Individualization, Interaction, and Immediate Feedback.
