The first essay of this dissertation examines the role of teacher characteristics in schools on student outcomes using datasets from TIMSS 1999 and TIMSS 2007 international tests. Taking an advantage that students have to take both mathematics and science subjects from different teachers, I use the method of First Difference (FD) analysis in order to remove the potential biases between teacher attributes and unobserved student characteristics. The findings show some contradictory outcomes between the FD analysis and ordinary least squares (OLS) analysis. The second essay looks into the problem of recruitment of well-qualified high school and college graduates to work as primary and secondary school teachers. I compare teacher salaries and benefits vis-à-vis other mathematics and science-oriented professions namely medical professions, engineers, accountants, scientists and nurses. In addition, I compare incomes between people who graduate from teacher colleges and non-teacher colleges. Using data from Thailand Labor Force Survey from 1985 to 2005, I find that teachers are the most poorly paid of all professions, including nurses. The difference in terms of an opportunity cost between male and female teachers is also striking. Among the graduates from teacher colleges, male graduates earn more than their peers if they chose other occupations whereas female graduates earn less if they make other choices. The third essay looks at the reasons teachers choose part-time jobs, the type of jobs they choose, and the amount of income they receive from these jobs, as well as factors influencing these decisions. I find that approximately 20-25% of Thai teachers participated in moonlighting activities. The majority of them have part-time jobs including tutoring, selling food and other products, and farming. Low salaries and high level of indebtedness are the most important factors associated with the increased likelihood of having a part-time job. However, economic status does not correlate significantly with their decision to tutor as their part-time job.

This interdisciplinary book offers a critical analysis of Thai education and its evolution, providing diverse perspectives and theoretical frameworks. In the past five decades Thailand has seen impressive economic success and it is now a middle-income country that provides development assistance to poorer countries. However, educational and social development have lagged considerably behind itsglobally recognized economic success. This comprehensive book covers each level of education, such as higher and vocational/technical education, and such topics as internationalization, inequalities and disparities, alternative education, non-formal and informal education, multilingual education, educational policy and planning, and educational assessment. The 25 Thai and 8 international contributors to the volume include well-known academics and practitioners. Thai education involves numerous paradoxes, which are identified and explained. While Thailand has impressively expanded its educational system quantitatively with much massification, quality problems persist at all levels. As such, the final policy-oriented summary chapter suggests strategies to enable Thailand to escape “the middle income trap” and enhance the quality of its education to ensure its long-term developmental success.
