Improving urban public schools: suggestions for teacher union leaders

In an earlier session of this conference, one participant asked the panelists what advice they would give to an audience of union leaders representing teachers from urban public schools. In response to that question, I offer seven suggestions. Following my explanations of those suggestions, I conclude with slightly different versions that I believe serve as relevant advice to local and state educational policymakers.Education

Improving the Performance of the Education Sector: The Valuable, Challenging, and Limited Role of Random Assignment Evaluations

In an attempt to improve the quality of educational research, the U.S. Department of Education%u2019s Institute of Education Sciences has provided funding for 65 randomized controlled trials of educational interventions. We argue that this research methodology is more effective in providing guidance to extremely troubled schools about how to make some progress than guidance to schools trying to move from making some progress to becoming high performance organizations. We also argue that the conventional view of medical research -- discoveries made in specialized laboratories that are then tested using randomized control trials -- is an inaccurate description of the sources of advances in medical practice. Moreover, this conventional view of the sources of advances in medical practice leads to incorrect inferences about how to improve educational research. We illustrate this argument using evidence from the history of medical research on the treatment of cystic fibrosis.

Standards, information, and the demand for student achievement

Higher student achievement, say the authors, has been severely hampered by a lack of good information comparing achievement levels with today's labor market requirements. They argue that by obtaining this information--in the form of academic standards and assessments--parents can more accurately evaluate the quality of their children's education.Education

Educating Urban Children

For a variety of reasons described in the paper, improving the performance of urban school districts is more difficult today than it was several decades ago. Yet economic and social changes make performance improvement especially important today. Two quite different bodies of research provide ideas for improving the performance of urban school districts. One group of studies, conducted primarily by scholars of organizational design, examines the effectiveness of particular district management strategies. The second, conducted primarily by economists, focuses on the need to improve incentives. Each body of research offers important insights. Each is somewhat insensitive to the importance of the insights offered by the other literature. A theme of this paper is that insights from both literatures are critical to improving urban school systems.

The Growing Importance of Cognitive Skills in Wage Determination

Using data from two longitudinal surveys of American high school seniors, we show that basic cognitive skills had a larger impact on wages for 24-year-old men and women in 1986 than in 1978. For women, the increase in the return to cognitive skills between 1978 and 1986 accounts for all of the increase in the wage premium associated with post-secondary education. We also show that high school seniors' mastery of basic cognitive skills had a much smaller impact on wages two years after graduation than on wages six years after graduation.

Who Benefits from Obtaining a GED? Evidence from High School and Beyond

This paper examines the value of the GED credential and the conventional high school diploma in explaining the earnings of 27-year-old males in the early 1990s. The data base is the High School & Beyond sophomore cohort. We replicate the basic findings of prior studies that implicitly assume the labor market value of the GED credential does not depend on the skills with which dropouts left school. We show that these average effects mask a more complicated pattern. Obtaining a GED is associated with higher earnings at age 27 for those male dropouts who had very weak cognitive skills as tenth graders, but not for those who had stronger cognitive skills as tenth graders.

Do the Cognitive Skills of School Dropouts Matter in the Labor Market?

Does the U.S. labor market reward cognitive skill differences among high school dropouts, the members of the labor force with the least educational attainments? This paper reports the results of an exploration of this question, using a new data set that provides information on the universe of dropouts who last attempted the GED exams in Florida and New York between 1984 and 1990. The design of the sample reduces variation in unmeasured variables such as motivation that are correlated with cognitive skills. We examine the labor market returns to basic cognitive skills as measured by GED test scores. We explore whether the returns differ by gender and race. The results indicate quite large earnings returns to cognitive skills for both male and female dropouts, and for white and non-white dropouts. The earnings payoff to skills increases with age.

Do Teacher Absences Impact Student Achievement? Longitudinal Evidence from One Urban School District

Rates of employee absences and the effects of absences on productivity are topics of conversation in many organizations in many countries. One reason is that high rates of employee absence may signal weak management and poor labor-management relations. A second reason is that reducing rates of employee absence may be an effective way to improve productivity. This paper reports the results of a study of employee absences in education, a large, labor-intensive industry. Policymakers' concern with teacher absence rests on three premises: (1) that a significant portion of teachers' absences is discretionary, (2) that teachers' absences have a nontrivial impact on productivity, and (3) that feasible policy changes could reduce rates of absence among teachers. This paper presents the results of an empirical investigation of the first two of these premises; it discusses the third premise. We employ a methodology that accounts for time-invariant differences among teachers in skill and motivation. We find large variation in adjusted teacher absence rates among schools. We estimate that each 10 days of teacher absences reduce students' mathematics achievement by 3.3 percent of a standard deviation.

Expanding School Enrollment by Subsidizing Private Schools: Lessons from Bogotá

Many countries use tax revenues to subsidize private schools. Whether these policies meet social objectives depends, in part, on the relative quality of education provided by the two types of schools. We use data on elementary school students and their teachers in Bogotá, Colombia to examine difference in resource mixes and differences in the relative effectiveness of public and private schools. We find that, on average, the schools in the two sectors are equally effective. However, they produce education using very different resource combinations. Moreover, there are large differences in the effectiveness of schools in both sectors, especially in the private sector. The results of our analysis shed light on the quantity-quality tradeoff that governments in many developing countries face in deciding how to use scarce educational resources.
