Abstract
The main purpose of this study is to examine the ICT integration into US public school curriculum and to propose five ICT integration models related to middle and high school course subjects. Based on the literature on ICT, curriculum, pedagogy and approaches to curriculum development were discussed. Then, two main ICT integration approaches from US public schools were explained. Finally, five ICT integration models; ICT as a subject matter, ICT as a cultural, mediational tool in the activity system in which students and teachers construct and co-construct new knowledge, ICT as a subject matter (one of the content area) that is integrated into a variety of other subject matters, such as math, science, literacy, and technology together, and as a Mixed Curriculum were proposed. It is believed that these models will expand the understanding of ICT integration into teaching and learning of middle and high schools subject matters
