While the number of universities in Vietnam has increased dramatically over the past decade, the country's poor quality of higher education has received much attention in recent times. The increasing number of university graduates without jobs and the number of university lecturers switching to other jobs is attracting many studies to find the causes, including public service motivation, job satisfaction, and teaching performance of university lecturers. This study aims to enrich the research literature and examine the role of service motivation as a moderator variable in the relationship between job satisfaction and teaching effectiveness of Vietnamese university lecturers. This study was conducted through a cross-sectional survey using a purposive sampling technique (n=200). Multivariable linear regression analysis and moderator regression were applied to test the proposed research hypotheses. Research results show a positive and significant relationship between satisfaction at work, motivation to serve the public, and teaching effectiveness of Vietnamese university teaching. In particular, public service motivation moderates the relationship between job satisfaction and the teaching performance of university lecturers in this country.

There are many factors affecting the quality of faculty that numerous researchers mentioned, analyzed and pointed out the different degrees of influence. The paper studies external factors affecting the quality of faculty such as Political regime, Management mechanism and Salary regime. These three factors have been existing in each country and make a different impact on the quality of faculty creating the unique characteristics of each country. The author builds a theoretical framework for research on the above-mentioned three ones and conduct a direct survey of 400 lecturers from 10 universities in Hanoi -the capital city of Vietnam. The survey is selectively done, in which its surveyed subjects are lecturers with doctorate or higher and their working time from 5 years or more. Through secondary data collected from published documents combined with those gained from direct investigations and surveys, the author contributes to clarifying the impact of the abovementioned factors on the quality of Vietnamese faculty. From that result, he proposes a number of workable solutions on the policies with the hope of providing leaders and managers with scientific arguments so that they have more sound bases to appropriately adjust their policies to satisfy the essential needs of lecturers, which helps them have more opportunities to create and maximize their capacity. That also contributes to completing the policies on developing a team of high-quality Vietnamese faculty meeting the requirements of higher education in the modern and integrated social context.
