This research evaluates technological equipment and its use in Secondary Education Institutions in Turkey. Specifically we examine teachers' use of new technologies in biology education. We locus on how frequently teachers use various computer applications and the conditions that prompt this usage. Our study also examines whether individual teacher characteristics affect changes in attitudes related to the implementation of technological supplements. The present research conducted via survey model was implemented with the support of MEB-EARGED. Data analysis was made by means of frequency analysis, Kruskal Wallis-H and Mann Whitney - U test processed with SPSS 15 for Windows. Research results indicate that even though secondary education institutions have satisfactory equipment in terms of new technologies, this quality does not appear in the class environments and education processes sufficiently. It was observed that a high ratio of teachers never use the new technologies in the teaching process and a rather low ratio uses the new technologies very frequently. Results show that there are significant differences between biology teachers' frequency of various computer applications. Variables are according to their seniority in the school system, the sort of the schools they work in, their access to and progress in training courses, and their own level of education.
