Mohammed, a 30-year-old Pakistani farmer with a primary school education, paid $4,000 to get a construction job in Saudi Arabia that paid $400 a month. Mohammed did not have the $4,000 to buy a work visa and pay agent fees and transportation costs, so he mortgaged his land, hoping to repay the loan with some of the $9,600 he expected to earn in Saudi Arabia over two years. With uncertain Pakistani earnings of $100 a month and a wife and four children to support, working abroad seemed the fastest way to achieve upward mobility at home, even if half of the expected extra income from working abroad went to recruiters and other components of the migration infrastructure....

This contribution describes the model for determining the number of pupils in the class of one teacher in primary school education in context of Slovak Republic. Actually, legislation defines the minimal and maximal number of pupils in the class. The model which we created is based on economic principles. These are usually different from “politically acceptable solutions”.Our model raises up from the presumption that greater is a number of pupils in the class the parents have to study more with their children at home and complete the work of teachers at home. But greater number of pupils in the class decreases medium labor costs for teacher per pupil. The simulation permit to define different range of parameters and to compare results for different variants. Keywords: pupils; class; number; parameters; simulation; cost function; Slovakia

The sudden shift to distance learning caused by the COVID-19 virus emergency has posed a serious challenge to schools. This article presents a successful model for applying the STEM approach in science education at the Alexander Georgiev-Kodzhakafaliyata Primary School in Burgas. In the conditions of synchronous distance learning in MS Teams environment, students conduct experiments with handy tools and materials at home, during online classes or as homework assignments, then describe the experiments in presentations and share them with their classmates during the project week ( April holidays and at the end of the year). The application of STEM home laboratory combines knowledge from different disciplines, diversifies and facilitates learning, enables learning by doing things, which most stimulates the curiosity of students. Thus, they casually acquire skills for planning and conducting a scientific experiment, generating hypotheses and reasoning, measuring results and formulating conclusions. At the same time, soft skills for teamwork, creative and critical thinking, presentation skills are formed and upgraded.

Coronavirus disease 2019 (COVID-19) often presents asymptomatically or milder in children compared to adults. The role of young children in the transmission of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) remains largely unknown. In the Netherlands, the first action of loosening the partial lockdown that had been implemented to reduce SARS-CoV-2 transmission was the reopening of primary schools on 1 May 2020. We subsequently conducted a prospective cohort study among healthcare workers (HCWs) with primary school-attending children versus HCWs without children living at home. We tested each HCW three times for SARS-CoV-2 from May 20 to June 15 2020 at 1-week intervals. In total, 832 nasopharyngeal swabs were taken from 283 HCWs with primary school-attending children living at home and 864 nasopharyngeal swabs from 285 HCWs without children living at home. All nasopharyngeal swabs tested negative for SARS-CoV-2. In our region with a low population density and low SARS-CoV-2 prevalence, reopening of primary schools did not lead to an increase in infections. The results of this study may serve as an example for the implementation of regional strategies to reduce SARS-CoV-2 transmission in countries with large variations in both population density and SARS-CoV-2 prevalence.
