The COVID-19 pandemic has caused a shift from on-campus to remote online examinations, which are usually difficult to invigilate. Meanwhile, closed-ended question formats, such as true–false (TF), are particularly suited to these examination conditions, as they allow automatic marking by computer software. While previous studies have reported the score characteristics in TF questions in conventional supervised examinations, this study investigates the efficacy of using TF questions in online, unsupervised examinations at the undergraduate level of Biomedical Engineering. We examine the TF and other question-type scores of 57 students across three examinations held in 2020 under online, unsupervised conditions. Our analysis shows significantly larger coefficient of variance (CV) in scores in TF questions (42.7%) than other question types (22.3%). The high CV in TF questions may be explained by different answering strategies among students, with 13.3 ± 17.2% of TF questions left unans
Researchers Study How Autistic People Communicate Virtually by Angela Mohan on March 16, 2021 at 3:12 PM
Autistic people prefer to communicate using the internet instead of in-person.
Researchers from Drexel University s A.J. Drexel Autism Institute collected and reviewed published research about how autistic youth and adults use the internet to communicate and provide a framework for understanding contributions, gaps and opportunities in online autistic communities.
Lead author Elizabeth McGhee Hassrick, PhD, an assistant professor in the Autism Institute, and her co-authors cast a wide net searching across five databases that list studies investigating how autistic people use the internet to communicate. Filtering for specific criteria, they read 32 articles, collected their most important findings and looked for patterns.
