In recent years, Government inputs has quite more of funding handling information studies, and in levels school in the General set computer classroom, makes now small and medium-sized school almost has computer in classes, but we of teachers really of has do computer technology into all subjects teaching did? this research will be the junior high school in mathematics for cases, hope inquiry current mathematics teachers in teaching use computer technology into teaching of using situations; also, "computer technology into teaching" Although meet world trend, but how the current implementation of the circumstances will be discussed in the research in depth.Most junior high school mathematics teacher for the practical implementation of information integrated into mathematics teaching, and how far? impact factor? this is another research motivation one of the researchers. In this study, the mathematics teachers in junior high school , information education, computer technology into their teaching and to explore the status and noun construction, while research deals, organize related literature in periodicals, including the development of our country’s education ideas related to evolution, computer technology into their teaching, factors affecting computer technology into their teaching and computer technology into mathematics teaching discussion of important issues, such as. Research by questionnaire method, and Li-Shan junior high school of Taipei city,Jie-Shou junior high school of Taipei city,Lu-Chou junior high school of New Taipei city,Ming-Chi junior high school of New Taipei city will be the choice, and four schools in the status of mathematics teachers in its use of computer technology into their teaching, conducts an in-depth study into; in accordance with the final findings, conclusions and recommendations. Research found, junior highs chool in the mathematics teachers in using information into mathematics teaching of status analysis in the to "School of teaching device" level of scored highest, but in "teachers of teaching policy" level in the of scored minimum, this reflect out computer technology into mathematics teaching in hardware aspects built reset perfect, but in "teachers of teaching policy" , is does not often will information technology into mathematics teaching implementation teaching process , its behavior performance bias negative to. Finally this study suggested that enhance teachers use of computer technology into their teaching will, more teachers in information-related diversification of studies, to strengthen students learning styles, the computer technology into their teaching, will have a more positive effect.
