Investigation of mobile learning with mobile phones for deaf students

（1）学习内容的发展我们总共开发了97项练习，是作为i-mode移动电话的独立应用而设计的，供主题：日语、英语、数学、科学、社会研究和信息技术使用。根据评估和学生的意见，我们用功能收集了练习：标记、重复、暂停和恢复、答案的解释。（2）分布和评估196名学生，总共有高中生和一所大学，用移动电话解决了这些练习。最后的分数，重复次数的数目和每一个学生在网络服务器上自动记录的数据库所需的总时间。“”Moreover，学生们要求回答一个网络问题。主要结果如下：·许多学生使用的练习有回答的方法和多种选择。相比之下，有些练习有回答的方法，填充空白是不受欢迎的。这可能是由于用移动电话输入单词或数字的不方便造成的，或者由于笔和纸张的使用来进行数学练习。就像我们的意图一样，许多练习都在10分钟内完成了。近70%的应答者同意使用移动电话作为一种新的学习方式（3）应用开发--机器人可以被移动电话的红外射线控制，被开发成一种学习材料。通过测试，从一台PC直接下载到一台新型移动电话的方法。通过使用无接触IC卡（Felica）的移动电话，我们测试了移动电话和Felica阅读器/写入器与USB接口连接的PC之间的数据通信。事实上，我们获得了在移动学习和个人电脑学习之间实现无缝连接的重要发现。

(1)Development of learning contentsWe developed 97 exercises in total, which are made as stand-alone applications for i-mode mobile phones, for the subjects : Japanese, English, mathematics, science, social studies and information technology. According to the evaluation and students' opinions, we equipped the exercises with the functions : marking, repetition, pause and resumption, explanations of answers.(2)Distribution and evaluation196 students in total of high-schools and a college solved the exercises with the use of mobile phones. The final score, the number of repetitions and total required time of every exercise for every student were automatically recorded into the database on a Web server. Moreover, the students were requested to answer a Web questionnaire. Main results are as follows :・Many students used the exercises which have the method of answering, multiple choice. By contrast, some exercises which have the method of answering, fill-in-the-blanks were unpopular. This may be caused by unease of inputting words or figures with a mobile phone, or by the use of pen and paper for mathematics exercises.・Just as our intended, many exercises were completed within 10 minutes.・Nearly 70% of the respondents agree with learning with a mobile phone as a new style of learning.(3)Applied developments・The robot which can be controlled by the infrared ray of a mobile phone was developed to be a learning material.・The method of direct downloading from a PC to a new type mobile phone via a USB cable were examined.・By using a mobile phone equipped with contactless IC card (Felica), we examined data communication between the mobile phone and a Felica reader/writer connected to a PC by the USB interface. Consequently, we obtained the significant findings toward the seamless connection between mobile learning and PC learning.
