The author has developed an integrated database storage and retrieval system based on a microcomputer. It would assist classroom teachers to obtain and process audio-visual materials and information on teaching materials for the purpose of realizing their teaching objectives and conducting effective classroom management. First, the central feature of this system is to be able to convert integratedly the numeric data in the file to pictorial and statistical ones through combining some application softwares based on the relational database system. Second, it is composed of six databases, that is, two kinds of audio-visual instructional materials databases, an achievement test scores database, a guidance database, a learner responding behaviors database, a sociometry database, and a file-processing utility. These all are easily and promptly presented and processed on a menustyled form. Third, the basic hardware composes of an 16-bittype microcomputer , an 80 x 40 character CRT display, a 20-megabyte type hard disk, two 5-inches type floppy disks, a 24-dotprinter, and a 2400-baud type modem. The aim of this study is to develop and evaluate the system described above. The survey was conducted to evaluate how this integrated system realized the aim of this study both before and after demonstrating and operating of this system. The participants of this survey was 11 graduate students who were elementary or secondary teachers from different areas in Japan. The results included the followings: (1) They showed positive attitudes to the integratedness of data-processing of this system. (2) But, they showed negative attitudes to the total collectiveness of different kinds of instructional information to perform the educational objectives.
