I am currently working in southern Vietnam on a government scheme as a teacher trainer to university lecturers and high school teachers. The overarching goal is to upgrade both English language skills and teaching practices. I would echo the above opinion that critical thinking is definitely not a prized quality in Vietnam-- not even amongst the ranks of the educators themselves. Perhaps the root cause may lie with singular political thought as mentioned, but I would posit that their deep roots in Confucian thought/education systems continue to waylay tendencies to critical thinking. Individually, great emphasis is placed on memorization, repetition and testing but dreadfully little on analysis, logic or long-term (strategic) planning. In groups, communication and teamwork tends to be poor, often marred by gender/social/economic divides and a cultural aversion to confrontation. It is generally a major loss of face to disagree with or criticize another person in a public forum. The result: 1) poorly conceived ideas or flawed logic is only rarely refuted in group scenarios; and 2) a sense that "nothing is mandatory" pervades-- in a work environment subordinates or coworkers will often simply ignore requests/orders that are inconvenient. Both can be averted by strong leadership... but will that leadership ever be developed?
