Increases in student achievement can be observed in classrooms where computers are used as essential tools in the curriculum. In contrast, when computers are used as supplemental to the curriculum—even in classrooms that are 1:1 (one laptop per student)—no increase in student achievement is observed. These claims are based on the analyses of a number of empirical studies of classroom computer use. We draw on the work of Project RED, a nationwide survey of classroom computer use, to identify the characteristics that distinguish between essential and supplemental use. This distinction is not an empty one; it could and should guide the next wave of 1:1 classrooms as mobile computing devices experience increased adoption. Indeed, the reality of every student having a computing device in the palm of his or her hand is within reach in the near term. However, if those computing devices are used as supplements to the curriculum then a great opportunity will be lost. In contrast, with a change in pedagogy and curriculum, K-12 education is poised to experience a dramatic increase in student achievement.

This work is based on the efforts of Dr. Chee- Kit Looi and his colleagues at the National Institute of Education, Singapore, and on the vision and cooperation of Chun Ming Tan, Principal of Nan Chiau Primary School, and Gene Lim, head of department and teacher at Nan Chiau. Two of Dr. Looi’s associates, Gean Chia and Peter Seow, in particular, have played major roles in the creation and enactment of the mobilized curriculum used at Nan Chiau. And we wish to acknowledge Jenny Lee and Shirlyn Cheng, teachers at Nan Chiau for their leadership in being early adopters of the mobilized curriculum. We (Norris and Soloway) proudly work with all the above as members of CERA—Center for Education Research and Action. CERA is a unique collaboration, housed at Nan Chiau Primary School, among academics, administrators, teachers, researchers, and commercial concerns. In a conversation with us at his home in Atlanta, Mark Weston (Rivero 2010) used the term “essential” in reference to the computer’s role in learning. Thank you, Mark, for sharing and for that pivotal conversation.
