This discrepancy is most prominent when C-tDCS is used to alter a cognitive function, questioning the assumption that cathodal stimulation always compromises performance. In this study, we aimed to study the...

Short Answer Grading: When Sorting Helps and When it Doesn’t

Automatic short-answer grading promises improved student feedback at reduced teacher effort both during and after instruction. Automated grading is, however, controversial in high-stakes testing and complex systems can be difficult to set up by non-experts, especially for frequently changing questions. We propose a versatile, domain-independent system that assists manual grading by pre-sorting ...
