I love that personal computing devices offer students a way to express their opinions without being called upon in front of the class. Incorporating a private learning space for students to get their thoughts down allows those who are uncomfortable with verbal participation to still interact with the class. I wish that I had a personal computing device throughout high school. As a student, I always take notes and think to myself, but when it comes to verbalizing my thoughts, I struggle. However, I have found that once sharing my thoughts with a small group, I am reassured that my ideas are valid, and have no problem sharing with the class. With a personal computing device, I would be able to organize my thoughts, validate them in my head, and then share with others. Using the "private space" would allow me to fit into the "public space" of the classroom much easier. My experience as a student is supported by Liu and Kao's study in the reading-- use the personal computer to do individual work, then share that work with a group and discuss your findings through large shared displays. I think that this way of learning and teaching promotes a socially supported learning environment (something I hope to have in my classroom).
Here's a parting quote from the reading to sum up my point: "Where individual computing devices succeed as private learning spaces, interactive whiteboards excel as public learning spaces. When paired with the necessary software and wireless connections, they can make transitions between individual or small-group learning and whole-class learning smooth" (6).
