Research of a CALL System with IC Tags

IC标签是一种可以附着在产品上或并入产品中的物体，用于使用无线电波进行识别。数据可以通过IC标签和转发器单元检索和存储。这种无线电通信技术预计将被纳入广泛的领域，如运输支付，产品跟踪，材料管理和传感器网络。本研究利用IC标签开发了一个计算机辅助语言学习（CALL）系统，其原型系统具有以下特点：（1）将IC标签贴在书本、塑料瓶等实物上，作为语言问题的选项。（2）该系统具有错误检查功能，根据学习者的错误，提供适当的错误信息，例如“不，不是在桌子上，而是在椅子上”。关于在语言问题中使用物理对象作为选项的观点，我们将IC标签的ID号与对象名称的文本数据和对象本身相关联。针对学习者的错误，我们准备了多种错误信息句型。系统检查他们的答案，并提供错误信息，指出错误的对象和错误的地方，以及正确的。错误信息是根据学习者的错误模式产生的，在原型系统上进行的实验表明，该系统运行稳定，主要有以下两点需要改进：（1）增加问题和提示信息的变化; (2)根据学习者的错误率和较高的词汇水平，需要一个支持性的反馈系统。

An IC tag is an object that can be attached to or incorporated into a product for the purpose of identification using radio waves. Data can be retrieved and stored with an IC tag and a transponder unit. This radio communication technology is expected to be incorporated in a wide range of fields, such as transport payments, product tracking, material management, and a sensor network. In this research we developed a Computer Assisted Language Learning (=CALL) system by using IC tags.A prototype system has the following features in order to introduce IC tags into language activities in a classroom: (1)IC tags are attached on the physical objects such as a book and a plastic bottle and etc to use them as options in the language questions. (2)This system is equipped with a mistake-checking function in which adequate error messages, such as "No, not on the table, but on the chair" are provided, depending on the learner's mistakes.In regard to the point of using physical objects as options in the language questions, we link ID numbers of the IC tags with the text data of the names of the objects, and the objects themselves. In regard to deal with the learner's mistakes, multiple sentence patterns of error messages am prepared. The system checks their answers and provides error messages which indicate the wrong object and the wrong place, as well as correct ones. The error messages are produced based on the learner's mistake patterns.As a result of experiments on this prototype system, stable operation was able to be carried out, The following 2 things are mainly cited as its future improvement, (1)variations of the questions and hint messages should be increased. (2) A supportive feedback system is needed, depending on the learner's error rate and higher vocabulary level.
