This behavior has traditionally been labeled as a form of gaming or help abuse. We propose that some examples of this behavior are not abusive and that bottom-out hints can act as worked examples.

Search and rescue robots are being used more frequently to access hazardous environments to assess situations and locate survivors. There are a wide range of existing mobile platforms for various situations and environments, but these robots are typically bulky, heavy or expensive, limiting their widespread and practical use in case of disaster mitigation.(More)
Students interacting with educational software generate data on their use of software assistance and on the correctness of their answers. This data comes in the form of a time series, with each interaction as a separate data point. This data poses a number of unique issues. In educational research, results should be interpretable by domain experts, which(More)
Methods for microfabrication of solderable and stretchable sensing systems (S4s) and a scaled production of adhesive-integrated active S4s for health monitoring are presented. S4s' excellent solderability is achieved by the sputter-deposited nickel-vanadium and gold pad metal layers and copper interconnection. The donor substrate, which is modified with "PI(More)
