Liu Hui and Molly are discussing the issue of educational quality at a workshop.

Liu Hui: Hi, Molly. Today's topic is educational quality. First, what does educational quality mean to you？

Molly: As far as I'm concerned, quality education means good learning standards in educational institutions. So, educational quality ensures a desirable outcome for learners.

Liu Hui: Sounds like after some serious thinking. However, many definitions of quality in education exist, testifying to the complexity and multifaceted nature of the concept.

Molly: Definitely, establishing a contextualized understanding of quality means including relevant stakeholders. Key stakeholders often hold different views and meanings of educational quality.

Liu Hui: There are many prestigious universities in the US. They all provide high-quality education. But some universities aren't known for their quality. It's hard to imagine the gap.

Molly: Yes, in the US the quality in higher education is quite mixed. Universities like Harvard, Yale, MIT, etc., you know, are well-known all over the world. However, there are some institutions providing poor education, so called “diploma mills”.

Liu Hui: In China, we have similar issues in educational quality. Some universities pay more attention to profits instead of quality.

Molly: How to improve educational quality is an international issue. But, solutions are grounded in values, cultures and traditions and may be specific to a given nation as well.
