This survey sought to identify variables related to teacher use of technology in secondary level geometry classrooms in southeastern Idaho. The primary variables examined in the study were teacher technology awareness, teacher attitude toward technology, teacher technology training, and teacher computer use for instruction. This study also tested for associations between these primary variables and principal attitude toward technology and a selected group of demographic variables: geometry teaching experience, number of sections of geometry taught, college mathematics major, and computer lab access. Four significant relationships were found. An inverse relationship was found between teacher computer use and the number of geometry sections taught. Direct relationships were found between teacher attitude and both teacher technology awareness and principal attitude. Finally, a direct relationship between type of teacher training and teacher instructional computer use was reported. (Contains 5 tables.)
