Kim Ki-hoon earns $4 million a year as a teacher in South Korea — at a private after-school tutoring academy, or hagwon:
Mr. Kim works about 60 hours a week teaching English, although he spends only three of those hours giving lectures. His classes are recorded on video, and the Internet has turned them into commodities, available for purchase online at the rate of $4 an hour. He spends most of his week responding to students’ online requests for help, developing lesson plans and writing accompanying textbooks and workbooks (some 200 to date).
South Korea has dramatically improved its education system over the past several decades:
Sixty years ago, most South Koreans were illiterate; today, South Korean 15-year-olds rank No. 2 in the world in reading, behind Shanghai. The country now has a 93% high-school graduation rate, compared with 77% in the U.S.
Of course, we might ask what the numbers look like for Korean-Americans.
Anyway, these private cram schools — as we called them back when these stories were about Japan — are big business:
Nearly three of every four South Korean kids participate in the private market. In 2012, their parents spent more than $17 billion on these services. That is more than the $15 billion spent by Americans on videogames that year, according to the NPD Group, a research firm. The South Korean education market is so profitable that it attracts investments from firms like Goldman Sachs, the Carlyle Group and A.I.G.
Students sign up for specific teachers, so “better” teachers get more students and make more money:
Performance evaluations are typically based on how many students sign up for their classes, their students’ test-score growth and satisfaction surveys given to students and parents. “How passionate is the teacher?” asks one hagwon’s student survey—the results of which determine 60% of the instructor’s evaluation. “How well-prepared is the teacher?” (In 2010, researchers funded by the Bill & Melinda Gates Foundation found classroom-level surveys like this to be surprisingly reliable and predictive of effective teaching in the U.S., yet the vast majority of our schools still don’t use them.)
[...]
All of this pressure creates real incentives for teachers, at least according to the kids. In a 2010 survey of 6,600 students at 116 high schools conducted by the Korean Educational Development Institute, Korean teenagers gave their hagwon teachers higher scores across the board than their regular schoolteachers: Hagwon teachers were better prepared, more devoted to teaching and more respectful of students’ opinions, the teenagers said. Interestingly, the hagwon teachers rated best of all when it came to treating all students fairly, regardless of the students’ academic performance.
Private tutors are also more likely to experiment with new technology and nontraditional forms of teaching.
