Income contingent student loans for Thailand: Alternatives compared

There is significant irresolution in many countries concerning the design of student loan schemes. In no country recently has there been more uncertainty as to the form that loans should take than Thailand. The Student Loans Fund (SLF), a conventional approach to financing, was introduced in 1996, discontinued at the end of 2005, and re-introduced in 2007. In its place an income contingent loan (ICL) was implemented for one year only, 2006. As part of this debate we contribute to an understanding of the repayment burdens associated with the SLF in Chapman, Lounkaew, Polsiri, Sarachitti and Sitthipongpanich (in this issue).     

Thailand's Student Loans Fund: Interest rate subsidies and repayment burdens

Government student loan schemes typically have implicit interest rate subsidies which, while these are a cost to taxpayers, they have the benefit of diminishing repayment burdens for graduates. Our goal is to illustrate the extent of both interest rate subsidies and repayment burdens with respect to Thailand's Student Loans Fund (SLF), using methods pioneered in measurement terms by 18 and 19.     

Are there peer effects associated with having English Language Learner (ELL) classmates? Evidence from the Early Childhood Longitudinal Study Kindergarten Cohort (ECLS-K)

Over the past decade, several state and federal policies have directed schools to mainstream English Language Learner (ELL) students into English-only instruction classrooms. While there is mixed evidence on the effects of these immersion policies on the ELL students, research examining potential peer effects on their non-ELL classmates is non-existent. This paper begins to fill in this gap by using a nationally representative longitudinal sample of children in early elementary grades. Results indicate that having an ELL classmate during kindergarten and first grade is associated with lower test score gains in reading but not necessarily in math for non-ELL students whose primary language is English, controlling for unobserved fixed school characteristics as well as individual characteristics. The negative peer effects on reading test score gain are sensitive to the frequency of within classroom ability grouping usage, gender, and household income level of non-ELL children.     

Back to school blues: Seasonality of youth suicide and the academic calendar

Previous research has found evidence of academic benefits to longer school years. This paper investigates one of the many potential costs of increased school year length, documenting a dramatic decrease in youth suicide in months when school is not in session. A detailed analysis does not find that other potential explanations such as economic conditions, weather or seasonal affective disorder patterns can explain the decrease. This evidence suggests that youth may face increased stress and decreased mental health when school is in session.     

Kindergarten skills and fifth-grade achievement: Evidence from the ECLS-K

Children enter kindergarten with disparate rudimentary reading and mathematics skills; capabilities for paying attention, sitting still and making friends; mental health; and inclinations for aggressive behavior. The role of these characteristics in producing fifth-grade school achievement is the subject of this paper. We find considerable impacts for school-entry academic skills but, with the exception of a kindergartener's capacity to pay attention, virtually no impacts for the collection of socioemotional skills. This finding holds both for the overall sample and for subgroups defined by race/ethnicity and socioeconomic status. The most powerful pre-school avenue for boosting fifth-grade achievement appears to be improving the basic academic skills of low-achieving children prior to kindergarten entry.     

Analyzing the factors that influence persistence rates in STEM field,majors: Introduction to the symposium

To improve our understanding of the factors that influence persistence rates in STEM field majors, the Alfred P. Sloan Foundation provided a grant to the Cornell Higher Education Research Institute in 2007 to study the question. The five papers in the symposium represent the output of the project. This introduction explains the motivation for undertaking the study, describes the questions the researchers asked and the data bases they used in their studies, summarizes their findings, and suggests directions for future research.     

Charter school authorizers and student achievement

In this paper we analyze the relationship between charter school authorizers and student achievement. We perform this analysis using a 10-year panel dataset from Minnesota, a state that permits four distinct types of authorizers—local school boards, postsecondary institutions, nonprofit organizations, and the Minnesota Department of Education. The results of the analysis indicate that there is no statistically significant relationship between charter school authorizing type and mean levels of student achievement. However, the analysis also reveals that schools authorized by nonprofit organizations exhibit substantially more variability in achievement than schools authorized by local school boards.     

The impact of a universal class-size reduction policy: Evidence from Florida's statewide mandate

Class-size reduction (CSR) mandates presuppose that resources provided to reduce class size will have a larger impact on student outcomes than resources that districts can spend as they see fit. I estimate the impact of Florida's statewide CSR policy by comparing the deviations from prior achievement trends in districts that were required to reduce class size to deviations from prior trends in districts that received equivalent resources but were not required to reduce class size. I use the same comparative interrupted time series design to compare schools that were differentially affected by the policy (in terms of whether they had to reduce class size) but that did not receive equal additional resources. The results from both the district- and school-level analyses indicate that mandated CSR in Florida had little, if any, effect on student achievement.     

The French zones d’éducation prioritaire: Much ado about nothing?

We provide an assessment of the French ZEP (Zones d’Education Prioritaire), a program started in 1982 that channels additional resources to schools in disadvantaged areas and encourages the development of new teaching projects. Focusing on middle-schools, we first evaluate the impact of the ZEP status on resources, their utilization (teacher bonuses versus teaching hours) and key establishments characteristics such as class sizes, school enrolments, teachers’ qualifications and experience, and student composition and mobility. We then estimate the impact of the ZEP program on four measures of individual student achievement: obtaining at least one diploma by the end of schooling, reaching 8th grade, reaching 10th grade and success at the Baccalauréat (the national examination at the end of high school). We take into account the endogeneity of the ZEP status by using both difference in differences and instrumental variables based on political variables. The results are the same in all cases: there is no impact on student success of the ZEP program.     

The adverse effects of parents’ school selection errors on academic achievement: Evidence from the Beijing open enrollment program

One major concern with public school open enrollment programs is the potential for parents’ school selection errors to adversely affect their children's academic achievement. In this study of the Beijing middle school open enrollment program, we estimate the degree to which children's school outcomes were negatively affected by the poor choices their parents made during the school selection process. We do this by examining parents’ responses to a survey on school choices combined with actual school applications, school admission records, and High School Entrance Examination test scores for 4717 students entering middle schools in Beijing via randomized lotteries. We find that the children of parents who made judgment errors in school selection were admitted to lower quality schools and achieved lower test scores on the High School Entrance Examination. Parents who had less education, whose children performed at lower levels in primary school, and who were less attentive to teachers’ opinions about schools were more prone to make these errors. Providing assistance to parents, especially those less prepared to make informed choices about school selection, is consequently important for supporting more efficient and equitable open enrollment programs.     

Estimating the impact of relative expected grade on student evaluations of teachers

Grade inflation over the past few decades has been a concern for many universities. Course evaluation scores are known to be positively correlated with students’ expected grades, and this paper tests whether or not there is an incentive for the instructor to “buy” higher evaluation scores by inflating grades. To test this hypothesis, I use unique data from the University of Washington's Office of Educational Assessment that includes a measure of each student's relative expected grade in the course. I find that there is an incentive for instructors to grade leniently after accounting for the potential endogeneity of the relative expected grade variable due to unobserved teacher productivity and unobserved heterogeneity of instructors and departments. Instructor fixed effects account for a significant part of the measured effect of relative expected grade on evaluations, and by not including them, the estimated impact of relative expected grade on evaluations is biased upwards.     

Recess, physical education, and elementary school student outcomes

Today's children experience a decreased amount of time at recess and fewer physical education (PE) classes throughout the school day. Breaks for physical activity limit class time for academics, potentially reducing learning. However, breaks may improve alertness and achievement. Using the Early Childhood Longitudinal Survey Kindergarten Class of 1998-1999, we evaluate how recess and PE in elementary school influence children's learning. We find no statistically significant or economically significant impacts of weekly recess or PE time on student learning for kindergarteners through fifth graders. For example, in kindergarten, adding an hour a week of recess reduces the average test score gain in reading by a statistically insignificant 0.01 standard deviations. An additional 49 min per week of PE in kindergarten improves reading test score gains by a statistically insignificant 0.05 standard deviations. We find no statistical difference in the male and female students’ response to recess and PE. Evidence suggests that recess and PE do not harm student outcomes.     

Do student migrations affect school performance? Evidence from Wisconsin's inter-district public school program

This paper examines the competitive effects of a unique school choice program implemented in the late 1990s, Wisconsin's open enrollment program, which allows families to send their children to schools outside their home district. In contrast to other school choice programs, districts not only face negative consequences from losing students and state funding, but they also stand to gain in the event of student emigration from other districts. The identification approach exploits differences in the number of schools in bordering districts, which affects inter-district ease-of-transfer. Estimates produce three main conclusions. First, districts that experience student out-migration produce higher standardized test scores in the subsequent year. Second, these effects are most evident among districts for which out-migration, expressed as a percentage of enrollment, falls in the upper quartile of all districts under consideration. Third, districts do not appear to respond to in-migration, indicating that districts place more emphasis on (and have more control over) preventing out-migration, as opposed to encouraging in-migration. These findings provide evidence that schools respond to competitive forces by improving quality.

Conditional cash penalties in education: Evidence from the Learnfare experiment

Wisconsin's influential Learnfare initiative is a conditional cash penalty program that sanctions a family's welfare grant when covered teens fail to meet school attendance targets. In the presence of reference-dependent preferences, Learnfare provides uniquely powerful financial incentives for student performance. However, a 10-county random-assignment evaluation suggested that Learnfare had no sustained effects on school enrollment and attendance. This study evaluates the data from this randomized field experiment. In Milwaukee County, the Learnfare procedures were poorly implemented and the random-assignment process failed to produce balanced baseline traits. However, in the nine remaining counties, Learnfare increased school enrollment by 3.5 percent (effect size = 0.08) and attendance by 4.5 percent (effect size = 0.10). These results suggest that well-designed financial incentives may be an effective mechanism for improving the school persistence of at-risk students at scale.     

Do teacher characteristics matter? New results on the effects of teacher preparation on student achievement

Research fairly consistently demonstrates that teachers are an important measurable factor in student learning, yet few teacher characteristics are shown to be consistently related to student achievement. Using a state administrative dataset that matches individual students to their teachers over time, I find that math teachers’ undergraduate performance, as measured by GPA (overall, math, and math education) and course hours (math and math education), is predictive of 5th grade math achievement. The effects of the teacher characteristics are mediated by years of experience and vary according to student types.     

Referral,enrollment, and completion in developmental education sequences in community colleges

After being assessed, many students entering community colleges are referred to one or more levels of developmental education. While the need to assist students with weak academic skills is well known, little research has examined student progression through multiple levels of developmental education and into entry-level college courses. The purpose of this paper is to analyze the patterns and determinants of student progression through sequences of developmental education starting from initial referral. Our results indicate that fewer than one half of the students who are referred to remediation actually complete the entire sequence to which they are referred. About 30 percent of students referred to developmental education do not enroll in any remedial course, and only about 60 percent of referred students actually enroll in the remedial course to which they were referred. The results also show that more students exit their developmental sequences because they did not enroll in the first or a subsequent course than because they failed or withdrew from a course in which they were enrolled. We also show that men, older students, African American students, part-time students, and students in vocational programs are less likely to progress through their full remedial sequences.     

The effects of accountability on higher education

This paper analyzes the effects of a higher education accountability system in Brazil. For each discipline, colleges were assigned a grade that depended on the scores of their students on the ENC, an annual mandatory exam. These grades were then disclosed to the public and colleges were rewarded or penalized based on them. I find that the ENC had a positive effect on the education and the proportion of full-time faculty and that it increased the number of vacancies offered, applicants and enrollments. Colleges were affected differently depending on grades, ownership and academic organization, changing the distribution of students among them.     

Teens’ alcohol consumption and schooling

While research outside economics has found that drinking has a negative effect on cognitive skills, some economists have failed to find any negative relationship between drinking and academic performance. This paper argues that the reason for this discrepancy is due to the way education is measured in the economic literature. Herein, binge drinking in the senior year of high school is found to reduce the probability of receiving a high school diploma and to increase the probability of graduating with a General Education Development (GED). Moreover, this study finds that alcohol policies do not affect the dropout rate measured at the age of 25, but they do affect the probability that a student will graduate on time. In conclusion, bingeing is found to be responsible for inducing individuals to temporarily drop out of school. Eventually, these individuals return to school to complete their education, most likely by obtaining a GED diploma.     

Educational attainment and HIV/AIDS prevalence: A cross-country study

Using data for a large cross-country sample, a reasonable model is estimated to judge the effect of adult educational attainment on prevalence of HIV. Three main points are noted. First, there is an indication of a significantly negative effect of educational attainment on HIV prevalence. Second, magnitude of the impact appears sizable. Third, a simple test suggests that the model does not have any major specification problem. Three additional aspects may also be interesting. First, the impact of per capita income is negative but statistically weak. Second, the effect of health expenditures lacks significance and does not carry the expected sign. Third, the proportion of population that is Muslim has a significantly negative association with HIV prevalence, perhaps reflecting the widely-shared view that male circumcision lowers acquisition of the disease.
