Is online learning necessarily constructivist in approach - the Korean context?

The fact that many Asians learn with the instructionist approach and still are successful makes me wonder. E.g. the Korean teachers of English I interviewed last year. They were aware of the two approaches but practised mainly if not only the instructivist approach. Their reason: cultural values. Korean culture is influenced by Confucian philosophy which emphasises deference to one's elders and figures of authority, unquestioning obedience and conformance to rules.

However, in international league tables, (South) Koreans do well in Maths and the sciences, but poorly in langauages. Korea leads in broadband penetration (place 7 in the world), computer to student ratio is one of highest in OECD, and online learning is already a feature of education there. This need not infer that Korean students engage successfully in online learning with a high degree of instructivist approach. Instead, Koreans were probably strong in these subjects before the advent of online learning. Would a study of the Korean wikipedia give clues to their learning approach (the more articles, the more they lean towards a constructivist approach)?
