How can we teach computational literacy to all levels of students?

In this paper, we discuss how to teach and learn computational literacy to all levels of students. Computational literacy is an important ability to understand and communicate information in current digital age and ubiquitous age. The digital has been used as a tool of communication along with language. Therefore, we would need to have ability to express our idea and understand an other's presentation with language and digital, which is just computational Literacy. However, most educators focus on using computer and internet, not computational literacy. Therefore, we define the operational definition about computational literacy suited for the present age by analyzing existing computational Literacy. In addition, we extract educational factors from the relation with computational thinking that is the purpose of computational literacy. Finally, we discuss teaching-learning strategy of computational literacy for all level s of students.
