Subclaims¶

q2 i? The review reports, citing Ogan et al. (2012), that computer sharing accounts for over 60% of use in developing areas in the Cognitive Tutor project. → Benjamin D. Nye 2015 q2 i? Multi-input shared systems such as MultiLearn+ (four users per laptop) and Single Display Groupware (whole class sharing one projection) lower hardware cost-per-student substantially. → Benjamin D. Nye 2015 (2)

The review reports this field finding from the Cognitive Tutor project, citing Ogan et al. (2012); the underlying study's design is not described in the review. Sharing has serious implications for user models that assume each machine measures one person's work.

"Recent findings from the Cognitive Tutor project show that computer sharing accounts for over 60 % of use in developing areas, with students leaving their own machines to share a machine instead (Ogan et al. 2012)."

The review describes multi-input ITS field systems, citing Brunskill et al. (2010) for MultiLearn+ and Alcoholado et al. (2012) for Single Display Groupware. Neither field study indicated that students exchanged or shared input devices extensively under these conditions.

"Since inputs are inexpensive compared to processors or displays, a four-user system like MultiLearn+ lowers the cost-per-student by almost three-quarters."
