The aim of the present study is to shed light on the conceptions that young students have of heat and temperature, concepts that are both important in school science curricula and closely related to daily life. The subjects of the study were students from a rural district in South Korea and they ranged in age from 4 to 11 years. Interviews were conducted with each student on the basis of questions on temperature, thermal insulation, and heat equilibrium. After calculating the frequency and percentage of student responses and analyzing the rationale for their answers, it was found that younger students tended to view temperature as ''size'' or a ''summation of numbers.'' This tendency gradually diminished in older students. Most students had alternative conceptions of thermal insulation regardless of age; however, reasoning differed according to age. Younger students displayed a greater tendency to view insulation as a material property, whereas older students showed a greater tendency toward rational heat and temperature conceptions. Most students did not have clear concepts of heat equilibrium regardless of age, but possessed numerous alternative conceptions. ß

This comparative study investigated how early childhood education and care practitioners in South Korea and Norway perceive the concept of children's well-being and their own roles in supporting and facilitating children's well-being. Data were collected through online questionnaires from 198 practitioners and analysed utilising chi-square analyses. The results showed that South Korean practitioners perceived the cognitive and economic domains as more important than Norwegian practitioners. Meanwhile, the practitioners from Norway perceived the social domain as more important than South Korean practitioners. Norwegian practitioners perceived physical needs, need for affection, and enjoyment as more important than Korean practitioners. Norwegian practitioners also monitored every child's well-being and more actively encouraged positive interactions and child-initiated activities. Meanwhile, Korean practitioners perceived the need for safety as important and believed that environments were not safe enough for children's health and well-being. These findings suggest that the educational approaches and sociocultural contexts of the two countries influence children's well-being.
