Industrial actions in schools: strikes and student achievement

Many jurisdictions ban teacher strikes on the assumption that they negatively affect student achievement, but there is surprisingly little research on this question. The majority of existing studies make cross‐section comparisons of the achievement of students who do or do not experience a strike. They conclude that strikes do not have an impact. I present new estimates of this impact of strikes using an empirical strategy that controls for fixed student characteristics at the school cohort level, and a sample of industrial actions by teachers in the province of Ontario. The results indicate that teacher strikes in grades 5 or 6 have a negative, statistically significant impact on test score growth between grade 3 and grade 6. The largest impact is on math scores: 29% of the standard deviation of test scores across school/grade cohorts.     

BEYOND TEST SCORES: THE IMPACT OF BLACK TEACHER ROLE MODELS ON RIGOROUS MATH TAKING

Rigorous math has a positive impact on ultimate educational attainment and earnings, but black high school students enroll in advanced math classes at low rates. Curriculum choice is determined by prior academic achievement and expectations for future schooling, both of which can be influenced by role models. This article finds that increasing the percentage of math teachers who are black has a nontrivial, positive impact on the likelihood that a black geometry student will enroll in a subsequent rigorous math course. This race-based role model effect occurs only for opposite-sex student/teacher matches.     

Middle school or junior high? How grade‐level configurations affect academic achievement

Does the grade‐level configuration of a school affect academic achievement? This research examines the effect of attending a middle/junior high school on academic outcomes in British Columbia, Canada, relative to attending a school from kindergarten through grade 8. Using an OLS strategy, I find that attending a middle/junior high school reduces grades 4 to 7 achievement gains in math and reading by 0.125–0.187 and 0.055–0.108, respectively. Similar‐sized estimates are found for math using a 2SLS strategy. Finally, large negative effects on grade 10 and grade 12 English exams are also found.     

The impact of teacher subject knowledge on student achievement: Evidence from within-teacher within-student variation

Teachers differ greatly in how much they teach their students, but little is known about which teacher attributes account for this. We estimate the causal effect of teacher subject knowledge on student achievement using within-teacher within-student variation, exploiting a unique Peruvian 6th-grade dataset that tested both students and their teachers in two subjects. Observing teachers teaching both subjects in one-classroom-per-grade schools, we circumvent omitted-variable and selection biases using a correlated random effects model that identifies from differences between the two subjects. After measurement-error correction, one standard deviation in subject-specific teacher achievement increases student achievement by about 9% of a standard deviation in math. Effects in reading are significantly smaller and mostly not significantly different from zero. Effects also depend on the teacher-student match in ability and gender.     

The impact of charter school attendance on student performance

We employ a panel of individual student data on math and reading test performance for five cohorts of students in Texas to study the impact of charter school attendance. We control for school mobility effects and distinguish movement to a charter school from movement within and between traditional public school districts. We find students experience poor test score growth in their initial year in a charter school, but that this is followed by recovery in the subsequent years. Failure to account for this pattern may lead to potentially misleading estimates of the impact of charter attendance on student achievement. Students who remain in charters largely recover from the initial disruption within approximately 3 years, and there is weak evidence that there may be overall gains from charter attendance within this period. Furthermore, students who return to traditional public schools after just 1 or 2 years in a charter do not appear to suffer a lasting negative impact despite their poor average performance in their first year of charter attendance.     

LOST IN TRANSLATION? TEACHER TRAINING AND OUTCOMES IN HIGH SCHOOL ECONOMICS CLASSES

Using data from a 2006 survey of California high school economics classes, we assess the effects of teacher characteristics on student achievement. We estimate value‐added models of outcomes on multiple choice and essay exams, with matched classroom pairs for each teacher enabling random‐effects and fixed‐effects estimation. The results show a substantial impact of specialized teacher experience and college‐level coursework in economics. However, the latter is associated with higher scores on the multiple‐choice test and lower scores on the essay test, suggesting that a portion of teachers' content knowledge may be “lost in translation” when conveyed to their students.

The impact of a study abroad programme on learning abilities and personality traits: evidence from a randomization

Personality traits are increasingly considered as a powerful predictor of socio-economic success as academic achievement. In this article, we exploit the random assignment of applicants to a programme in order to retrieve unbiased estimates of the impact of studying abroad on both cognitive and noncognitive abilities. Our findings suggest that secondary school students, especially those considered ‘more able’, benefited from a 1-month experience abroad, as it enhanced both personality traits and language proficiency.     

Stuck in the middle: Impacts of grade configuration in public schools

We examine the implications of separating students of different grade levels across schools for the purposes of educational production. Specifically, we find that moving students from elementary to middle school in 6th or 7th grade causes significant drops in academic achievement. These effects are large (about 0.15 standard deviations), present for both math and English, and persist through grade 8, the last year for which we have achievement data. The effects are similar for boys and girls, but stronger for students with low levels of initial achievement. We instrument for middle school attendance using the grade range of the school students attended in grade 3, and employ specifications that control for student fixed effects. This leaves only one potential source of bias–correlation between grade range of a student's grade 3 school and unobservable characteristics that cause decreases in achievement precisely when students are due to switch schools–which we view as highly unlikely. We find little evidence that placing public school students into middle schools during adolescence is cost-effective.     

DOES TEACHER QUALITY AFFECT STUDENT PERFORMANCE? EVIDENCE FROM AN ITALIAN UNIVERSITY

In this paper, we analyse whether the characteristics of university teaching staff matter with regard to students' performance and interest in the discipline. We use data on about 1000 students enrolled on the first-level degree course in business and economics at a medium-sized Italian university. Thanks to the random assignment of students to different teaching classes during their first year, we are able to analyse the effect that teachers with different characteristics, in terms of experience and research productivity, produce both on students' performance, measured in terms of the grades obtained at subsequent examinations, and on courses chosen. Our results suggest that teacher quality has statistically significant effects on students' grades in subsequent courses. These effects are also robust after controlling for unobserved individual characteristics. On the other hand, we find less clear evidence when relating teacher quality to student involvement with a subject. It emerges that research productivity does not produce a statistically significant effect on the probability of a student undertaking additional courses in a subject, while more experienced teachers have a negative impact. However, also this effect does not become statistically significant when we run separate regressions for different disciplines.     

Teacher training for PhD students and new faculty in economics

Past studies suggest that a majority of economics graduate students engage in teaching-related activities during graduate school and many go on to academic positions afterwards. However, not all graduate students are formally prepared to teach while in graduate school nor are they fully prepared to teach in their first academic position. The authors characterize current teaching experience and training of graduate students from the point of view of directors of graduate studies and of newly minted academic economists. The authors also query department chairs and new faculty about teacher training, support available for new faculty, and the degree to which newly hired Ph.D. economists are prepared to teach. Findings indicate that while some training is available, there is room for enhancing teacher training in economics.     

Participation in school-sponsored sports and academic spillovers: new evidence from the early childhood longitudinal survey

The link between participation in school-sponsored sports and academic performance has been studied extensively in the literature. Whilst previous studies tend to show positive academic spillovers, it remains unclear whether these positive associations are primarily driven by selection into sports. We investigate this issue using data on middle school children drawn from the Early Childhood Longitudinal Study, Kindergarten Class of 1998–1999. Due to the lack of credible instrumental variables for sports participation, we establish bounds for the relationship between school sports and academics using a combination of the propensity score matching method and an approach that uses selection on observed factors as a guide to selection on unobserved factors. We find that the association between participation in school-sponsored sports and academic performance as measured by standardised test scores in reading, math and science ranges from null to negative. Overall, our results suggest that failure to account for selection may result in a misleading positive correlation between sports participation and academic performance.     

Peer effects in Austrian schools

This study deals with educational production in Austria and is focused on the impact of schoolmates on students’ academic outcomes. We use PISA 2000 and 2003 data to estimate peer effects for 15 and 16 year old students. School fixed effects are employed to address the potential self-selection of students into schools and peer groups. The estimations show significant positive effects of the peer group on students’ reading achievement, and less so for mathematics. The peer effect in reading is larger for students from less favorable social backgrounds. Furthermore, quantile regressions suggest peer effects in reading to be asymmetric in favor of low-ability students, meaning that students with lower skills benefit more from being exposed to clever peers, whereas those with higher skills do not seem to be affected much.     

THE IMPACT OF PUBLICLY PROVIDED EARLY CHILDHOOD EDUCATION PROGRAMS ON DISTRICT‐LEVEL TEST SCORES

While the existing literature largely finds that standardized test scores are positively associated with participation in pre‐kindergarten programs at the student level, there is little research on the policy effect of publicly providing these programs to entire school districts. We attempt to partially fill this void by examining the effect that publicly provided pre‐kindergarten and full‐day kindergarten programs have on fourth grade student achievement in math and reading at the district level. The models utilize panel data from districts in Wisconsin along with fixed effects estimations. We find that once time‐invariant unobserved heterogeneity of a district is accounted for, preschool programs have small but significant impacts on a cohort's future math scores, particularly in less‐educated communities. Additionally, there is no evidence that preschool or full‐day kindergarten has an impact on future reading scores at the district level. (JEL I20, I28)     

Evaluating the magnitude and the stakes of peer effects analysing science and math achievement across OECD

What follows is an exercise aimed at estimating peer effects' impact on science and math test scores of secondary school students surveyed in 1995 by the International Education Agency across OECD countries. It is also to discuss their importance for educational policy, particularly regarding the highly sensitive issue of ability-grouping. Using this unique international database. This study assesses the magnitude of the peer effect relative to more traditional inputs. Referring to education policy stakes, we control for the presence of increasing or decreasing return. This study also checks for cross effects in order to determine whether peer effects matter more to low or high SES pupils, and whether their final impact on achievement is affected by the underlying level of heterogeneity within the group. Using a methodology, which a priori accounts for the clustering of the data within countries and schools/classrooms - i.e. fixed/random effect or hierarchical model - our analysis indicates that peer effects are strong determinants of both math and science achievement relative to individual SES and other school inputs. The presence of increasing of decreasing returns is not obvious. But we find systematic evidence that low-ability pupils are more sensitive to peer group characteristics. By contrast, this study also find that - for a given level of the peer effect - higher heterogeneity comes at a certain cost. In brief, these results provide no systematic evidence regarding grouping policies.     

How important are school principals in the production of student achievement?

As school leaders, principals can influence student achievement in a number of ways, such as hiring and firing of teachers, monitoring instruction and maintaining student discipline, among many others. We measure the effect of individual principals on gains in math and reading achievement between grades 4 and 7 using a value‐added framework. We estimate that a one standard deviation improvement in principal quality can boost student performance by 0.289 to 0.408 standard deviations in reading and math, while the principal at the 75th percentile improves scores by 0.170 to 0.193 relative to the median principal. Our results imply that isolating the most effective principals and allocating them accordingly between schools can have a significant positive effect on reducing achievement gaps.     

Teacher unions, teacher pay and student performance in India: A pupil fixed effects approach

This paper examines the relationship between teacher unionization, student achievement and teachers' pay using a cross-section of data from private schools in India. We use differences in student mark across subjects to identify within-pupil variation in achievement and find that union membership of the teacher is associated with reduced pupil achievement. We find no evidence this could be due to the unobservables not controlled for by this procedure. A school fixed effects equation of teacher pay shows that union membership raises pay and in this case too we find that remaining unobservables are unlikely to explain this outcome. We discuss the policy implications of the findings and show that the effectiveness of teacher credentials in improving teacher performance is linked to unionization.     

Measuring peer effects in the Brazilian school system

Using the identification strategy proposed by Graham and Hahn (2005), we estimate the magnitude of classmate effects on math scores using Brazilian data from 2005. In addition, we provide a detailed discussion about the identification of endogenous peer effects in the linear in means models. Our results show that both peer characteristics (exogenous peer effects) – like race, socioeconomic status and gender – and peer actions (endogenous peer effects) are important determinants of students’ outcomes in the fifth grade of elementary school. Our estimates of endogenous peer effects are about 0.008 of 1 SD of math test scores, which can be interpreted as evidence of a so-called ‘conformist’ individual behaviour, under which students face large costs to exert effort levels that are distant from what is believed to be the norm in the classroom. Those estimates of endogenous peer effects imply a social multiplier of about 1.67.     

Does weight status affect academic performance? Evidence from Australian children

This article investigates the impact of children’s weight status on their academic performance using the Longitudinal Survey of Australian Children. Considering the endogeneity of the weight status variable (obesity or overweight), to obtain consistent estimates of its impact, we use the body mass index of biological parents as instrumental variables. The two-stage least square estimation shows that obesity or overweight has a significant negative impact on academic performance. Furthermore, the effect of child weight status is different across grade levels. Overweight has a larger negative impact on academic performance for senior year students, especially on numeracy.     

Racial diversity and academic test scores in public elementary schools

This article examines the effect of racial diversity on academic achievement using panel data on San Francisco’s public elementary schools from 2003 to 2007. Theories argue that the relationship between racial diversity and academic achievement may be positive or negative. Few studies have examined the effect of racial diversity in US elementary schools. Fixed effects models are used to examine the relationship between racial diversity and academic performance in elementary schools. Controls for student differences and teaching staff differences are added as part of the education production function literature. Results show that racial diversity has little effect on academic achievement scores.     

Resources and Student Achievement—Evidence from a Swedish Policy Reform*

A policy change is used to estimate the effect of teacher density on student performance. We find that an increase in teacher density has a positive effect on student achievement. The baseline estimate—obtained by using the grade‐point average as the outcome variable—implies that resource increases corresponding to the class‐size reduction in the STAR experiment (a reduction of seven students) improves performance by 2.6 percentile ranks (or 0.08 standard deviations). When we used test‐score data for men, potentially a more objective measure of student performance, the effect of resources appears to be twice as large.
