Experiences With Online Teaching and Psychological Adjustment of High-School Students at the Onset of the COVID-19 Pandemic in Croatia.

Vastly changed schooling arrangements due to the COVID-19 crisis have generally limited the opportunities and resources for schools to provide necessary psychological and other support to their students. Given this, all parties involved in the schooling system need to understand the kinds of experiences students have via distance learning and how students adapt to novel living and studying conditions. This study examines the relevant sources of stress that students encounter with regard to online classes, and the frustrations they face due to living in social isolation, as well as how these stressors relate to the measures of students' emotional wellbeing and psychological adjustment. Data were collected in April 2020 via an online questionnaire administered to a sample of 4,492 students (62.6% female) attending all four grades of high school within two Croatian counties. The results point to the differential effects of particular aspects of online teaching practices on the stressful experiences of students. Furthermore, the results of multivariate analysis of variance and canonical discriminant analyses demonstrated notable gender and grade differences in the structure of students' emotional and behavioral adaptation to the health crisis. Female students and those predominantly studying at the highest grade reported higher frequency and intensity of short-term emotional and psychosomatic difficulties. Male students in the final grade year scored highest on the dimension defined by the number and intensity of online teaching stressors. The results are interesting in light of hypothetical accounts of adjustment mechanisms based on existing stress theories. Moreover, the findings serve as a basis for teachers' self-reflection and self-evaluation of schools, which can then lead to designing specific programs of support in learning and adaptation to the new living and studying conditions.
