“…Interestingly overall, the students achieved higher marks when compared with a cohort that studied the unit exclusively on campus with a supervised closed-book summative exam ( 61 ). One reason may be less stress in the former, given that previous studies have demonstrated that stress undermines learning and cognitive processes ( 69 , 70 ). Students preparing for open-book exams or quizzes may be required to utilize learning strategies based on higher order thinking rather than being structured around student recall of content ( 71 , 72 ).…”

The COVID-19 pandemic has been a strong driver for moving more teaching and learning activities online. Border restrictions have had a severe impact on international students either hoping to enrol in courses offered in Australia or continue with such courses if they are already enrolled. The online learning experience is likely different between students onshore and offshore. This study took a unique opportunity to investigate any such differences in students' attitudes towards remote learning, necessitated by the pandemic, by comparing two cohorts of students, Australia- vs. China-based. The preferences of students based in Australia as to remote learning were commonly about the convenience of attendance and availability of the video recordings, whereas the latter was not considered likely were the classes delivered face-to-face instead. However, students in China had a strong preference for face-to-face sessions, with the lack of prior experience in an English-speaking learning environment and hesitance to speak with the lecturers and engage in the learning activities possible reasons for this. In quizzes, students in Australia performed better than those in China regardless of local or international student status. This difference may be due to the Australian-based students' prior experience of English-speaking environments and open-book quizzes. In conclusion, remote learning in a familiar language and learning environment is accepted by students, whereas if the teaching is delivered in a second language using unfamiliar teaching methods, remote learning will require additional scaffolding to enhance their learning experience

“…Fear, anxiety, and constant worrying and racing thoughts are concluded as cognitive stress. [ 1 ] In comparison, neurological stresses are caused by neurological disease. One of the most significant factors that can affect mental health is stress.…”

Stress can lead to harmful conditions in the body, such as anxiety disorders and depression. One of the promising noninvasive methods, which has been widely used in detecting stress and emotion, is electrodermal activity (EDA). EDA has a tonic and phasic component called skin conductance level and skin conductance response (SCR). However, the components of the EDA cannot be directly extracted and need to be deconvolved to obtain it. The EDA signals were collected from 18 healthy subjects that underwent three sessions – Stroop test with increasing stress levels. The EDA signals were then deconvoluted by using continuous deconvolution analysis (CDA) and convex optimization approach to electrodermal activity (cvxEDA). Four features from the result of the deconvolution process were collected, namely sample average, standard deviation, first absolute difference, and normalized first absolute difference. Those features were used as the input of the classification process using the extreme learning machine (ELM). The output of classification was the stress level; mild, moderate, and severe. The visual of the phasic component using cvxEDA is more precise or smoother than the CDA's result. However, both methods could separate SCR from the original skin conductivity raw and indicate the small peaks from the SCR. The classification process results showed that both CDA and cvxEDA methods with 50 hidden layers in ELM had a high accuracy in classifying the stress level, which was 95.56% and 94.45%, respectively. This study developed a stress level classification method using ELM and the statistical features of SCR. The result showed that EDA could classify the stress level with over 94% accuracy. This system could help people monitor their mental health during overworking, leading to anxiety and depression because of untreated stress.

“…The research showing the effects of stress on cognitive functioning is based on two basic approaches (Stawski et al 2006). First, according to the theory of appraisal, when individuals deem life stressful, cognitive resources must be allocated to cope with environmental demands, thus reducing the resources available to perform cognitive functions (Bakker & Demerouti 2017, Calvo & Gutierrez-Garcia 2016. In this sense, several studies of aging have provided similar findings, indicating that individuals who report higher levels of subjective distress exhibit poor episodic memory, fluid intelligence and processing speed performance, as well as an increased risk of cognitive decline (Perrotin et al 2017;Wilson, et al 2005).…”
