Grant-in-Aid for challenging Exploratory Research，2012.04 - 2015.03，The Development and Validation of a Computer-Mediated Semi-Direct Test for Japanese Senior High School Students through Action Research

This study investigated the usefulness of a computer-mediated semi-direct test (hereafter CST) at a Japanese senior high school. The test, which has three evaluation items, fluency, correctness, and prosody, was developed through action research. The usefulness was examined in terms of validity, reliability, and practicality with the help of the Many-Faceted Rasch Measurement. As a result, some empirical evidence for construct validity was confirmed, and other forms of evidence were shown in terms of face validity. Inter-rater reliability between the two raters and each rater's intra-rater reliability were found. Also, practicality was confirmed regarding the time spent conducting the test. In conclusion, some evidence for the usefulness was revealed and this suggests that CSTs might be one effective means to improve the rate of use of performance-based English speaking tests in high school.

Grant-in-Aid for Scientific Research(B)，2006.04 - 2009.03，Incorporation of Time-scale Modification of Teaching Materials with or without Subtitles into Learning and Instructional System for Foreign Language Education

Grant-in-Aid for Scientific Research(B)，2002.04 - 2005.03，Incorporation of Three Infra-red Rays Transfer on the Different Wavelength into Learning and Instructional System for Foreign Language Education

This research was undertaken to assess the value of the possible instruction system where an instructor can administer to language learners at a free multimedia instructing and learning layout.
This instruction system was made possible with the use of the light diffusion-transfer infra-red ray transmission system and a notebook computer. The system can use three different wavelengths. The first one is used for transferring NTSC (National Television Standards Committee) signal with analog spectrum. This transmission causes no delay distributing information from the instructor to the learners. The rest of them are used for wireless LAN utilizing infra-red ray. This system of the LAN uses CSMA/CD (Carrier Sense Multiple Access with Collision Detection) which has been adopted in IEEE802.3 10BASE-T, thus excelling CSMA/CA (CSMA with Collision Avoidance) in detecting a signal collision.
There is, however, a next research issue found in the system. The system could operate the two functions simultaneously, by presenting audio-visual teaching materials to learners, and the learners controlling the playback of the materials by themselves. Then, the further research accounting for the effective chemistry between the two is needed.
This research has arrived at the conclusion where foreign language education utilizing three infra-red rays transfer on the different wavelength may rejuvenate and even economize the whole education plan, in that instructors and learners only need to bring in their own notebook computers into the ordinary classroom, not into an extravagant LL or a computer room.

Grant-in-Aid for Scientific Research(B)，1998.04 - 2001.03，Incorporation of the Wireless Infrared Ray Transmission into Learning and Instructional System for Foreign Language Education

This research was undertaken to assess the value of the possible LAN instruction system where an instructor can administer to language learners at a free instructing layout.
This instruction system was made possible with the use of the light diffusion-transfer wireless infrared ray transmission system and a notebook computer. The system uses CSMA/CD (Carrier Sense Multiple Access with Collision Detection) which has been adopted in IEEE802.3 10BASE-T, thus excelling CSMA/CA (CSMA with Collision Avoidance) in detecting a signal collision.
In the system a program to transfer information between an instructor and learners in a computer class is being operated. In addition, two-way voice communication system between an instructor and learners is built in. This resulted in the instruction system to cope with the need of improving four skills as "reading," "writing," "listening," and" "speaking".
There is, however, a problem found in the system, in that the two-way voice communication system can not be operated real-time. As sound gaps seen in satelite broadcasting and heard in overseas calls often discomfort us, the sound gap of over one-second delay has been observed.
This research has arrived at the conclusion that foreign language education utilizing wireless infrared ray transmission system may convenience and even economize the whole education plan, in that learners only need to bring in their own notebook computers into the ordinary classroom, not an extravagant LL or a computer room.

Grant-in-Aid for Scientific Research(B)，1998.04 - 2001.03，Foreign Language Education Utilizing Wireless Infrared Ray Transmission System

Studies of a foreign language instruction system have been carried out by means of wireless LAN with optical diffusion method and note PCs, which do not limit location.
Chief characteristics of the system employed in our studies are described in the fllowings. First, CSMA/CD (Carrier Sense Multiple Access with Collision Detection) adopted in IEEE802.3 10BASE-T is employed.It has exceeding advantage of collision detection of signals over CSMA/CA (CSMA with Collision Avoidance). Second, software is in operation, which is used in a typical computer room. It can transmit information bi-directionally from an instructor to learners and vice versa. The information here includes graphical information in display and saved files. Bi-directional digital transmission of speech sounds between an instructor and learners is added to its software used at a typical computer room. Third, an instructor can handle a group of learners individually in this system.
It has turned out that the system can be used effectively and extensively in foreign language instructions. It can be applicable to every aspect of four skills, that is, reading, writing, listening and writing.
A little problem is found. A transmission lag of speech sounds over one second has been detected. Most of us have already experienced this kind of lag in an overseas call and a TV program to find that it makes communication somewhat difficult.
In conclusion, we have found possibilities to go beyond the specific restriction of facilities such as an LL and a computer room. Infrared ray transmission can be located on almost all classroom ceilings. If you bring your note PC compatible with optical LAN, then you can build up your instruction system freely within its effective area.
