Research of a CALL System with IC Tags

IC标签是一种可以附着在产品上或集成到产品中的物体，目的是使用无线电波进行识别。数据可以通过一个IC标签和一个应答器单元进行检索和存储。这种无线电通信技术有望被广泛应用于运输支付、产品跟踪、材料管理和传感器网络等领域。在本研究中，我们开发了一个使用IC标签的计算机辅助语言学习（=CALL）系统。将集成电路标签引入课堂语言活动的原型系统具有以下特点：(1)将集成电路标签贴在书本、塑料瓶等实物上，作为语言问题的选项。(2)该系统具有检错功能，根据学习者的错误情况提供适当的错误提示，如“No, not on the table, but on the chair”。关于在语言问题中使用物理对象作为选项的问题，我们将IC标签的ID号与对象名称的文本数据以及对象本身联系起来。在处理学习者的错误方面，准备了多种错误信息句型。系统检查他们的答案，并提供错误消息，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。通过对该原型系统的实验，可以实现系统的稳定运行，今后需要改进的地方主要有以下两点：(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.
