Six observation scales for measuring the skills of teachers and 1 scale for measuring student engagement, assessed in South Korea and The Netherlands, are sufficiently reliable and offer sufficient predictive value for student engagement. A multigroup confirmatory factor analysis shows that the factor loadings and intercepts of the scales are the same, within acceptable boundaries, in both countries. Therefore, we can compare the average scores of teachers in both countries in a reliable and valid way. The 289 Dutch teachers score significantly better on "creating a safe and stimulating learning climate" and "intensive and activating teaching" and almost significantly on "efficient classroom management". We find no significant differences in "clear and structured instruction". The 375 South Korean teachers perform significantly better than the Dutch teachers on "teaching learning strategies" and almost significantly on "differentiating instruction". Furthermore, we find better student engagement in South Korea. ARTICLE HISTORY

The friendships of college students in the United States (n= 61), Indonesia (n= 56), and South Korea (n= 35) were assessed to evaluate the H. C. Triandis, R. Bontempo, M. J. Villareal, M. Asai, and N. Lucca (1988) hypothesis that the friendships of individuals in collectivist cultures are more intimate and less extensive than those in individualistic cultures. Students rated the qualities of their friendships, reported the identity and characteristics of friends, and recorded details of their social interactions using the Rochester Interaction Inventory. The friendship characteristics of South Korean students were generally consistent with the H. C. Triandis et al. (1988) hypotheses, whereas those of the Indonesian students were not. It appears that friendships in some collectivist cultures, including Indonesia, display characteristics of extensive social contacts with others in conjunction with limited intimacy with specific individuals.

Differentiated instruction is considered to be an important teaching quality domain to address the needs of individual students in daily classroom practices. However, little is known about whether differentiated instruction is empirically distinguishable from other teaching quality domains in different national contexts. Additionally, little is known about how the complex skill of differentiated instruction compares with other teaching quality domains across national contexts. To gain empirical insight in differentiated instruction and other related teaching quality domains, cross-cultural comparisons provide valuable insights. In this study, teacher classroom practices of two high-performing educational systems, The Netherlands and South Korea, were observed focusing on differentiated instruction and other related teaching quality domains using an existing observation instrument. Variable-centred and person-centred approaches were applied to analyze the data. The study provides evidence that differentiated instruction can be viewed as a distinct domain of teaching quality in both national contexts, while at the same time being related to other teaching domains. In both countries, differentiated instruction was the most difficult domain of teaching quality. However, differential relationships between teaching quality domains were visible across teacher profiles and across countries.
