This study investigated cross-nationally preservice teachers' perceptions of the effectiveness of computers and technology in improving education. Participants were undergraduate education students from the United States and Taiwan; 180 students from each country were randomly selected. A survey instrument that identified types and amounts of technology resources generally found in elementary, middle, and high schools was used. The results indicate that preservice teachers in both countries valued a computer lab in each school and computers in each classroom higher than interactive video equipment or calculators. They also thought that these technology resources were more important and useful for students in high schools than in elementary or middle schools. Preservice teachers in the United States had more positive perceptions of the effectiveness of technology resources in improving education than their counterparts from Taiwan. Findings of this study and their educational implications are discussed. (Contains 1 table and 22 references.) (Author/AEF)
