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.     

A new international database on education quality: 1965–2010

The aim of this article is to propose a new database allowing a comparative evaluation of the relative performance of schooling systems around the world. We measure this performance through pupils’ achievement in standardized tests. We merge all existing regional and international student achievement tests by using a specific methodology. When compared with other existing databases, our approach innovates in several ways, especially by including regional student achievement tests and intertemporal comparable indicators. We provide a data set of indicators of quality of student achievement for 103 countries/areas in primary education and 111 countries/areas in secondary education between 1965 and 2010.     

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.     

Accountability,incentives and behavior: the impact of high-stakes testing in the Chicago Public Schools

The recent federal education bill, No Child Left Behind, requires states to test students in grades 3 to 8 each year and to judge school performance on the basis of these test scores. While intended to maximize student learning, there is little empirical evidence about the effectiveness of such policies. This study examines the impact of an accountability policy implemented in the Chicago Public Schools in 1996–1997. Using a panel of student-level, administrative data, I find that math and reading achievement increased sharply following the introduction of the accountability policy, in comparison to both prior achievement trends in the district and to changes experienced by other large, urban districts in the mid-west. However, for younger students, the policy did not increase performance on a state-administered, low-stakes exam. An item-level analysis suggests that the observed achievement gains were driven by increases in test-specific skills and student effort. I also find that teachers responded strategically to the incentives along a variety of dimensions—by increasing special education placements, preemptively retaining students and substituting away from low-stakes subjects like science and social studies.     

A signalling model of school grades under different evaluation systems

We examine the role of school grades as a signal of worker productivity under different examination systems in relation to errors that may affect student performance. Firms use school grades as a signal of workers’ effective skills, taking into account that these evaluations are effected by stochastic shocks. We show that more precise evaluation systems, being associated with a higher reactivity of wages to school grades, induce students to provide more effort. Low ability students tend to react less than high ability students. Moreover, individuals with low abilities may prefer less accurate evaluation systems. Nevertheless, when productivity increases, these systems become less convenient and the number of individuals preferring them diminishes. Our analysis highlights an important trade-off between centralised and decentralised evaluation systems. On the one hand, frequent evaluations, typical of decentralised systems, weaken the impact on grades of those errors which influence student performance and, so, reduce signal noise, while, on the other hand, different teachers generally adopt different performance assessment standards, leading to noisier evaluations.     

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.     

Cost and learning efficiency drivers in Australian schools: a two-stage network DEA approach

This article explore performance issues in Australian public schools, using a two-stage DEA network model, which accounts simultaneously for both cost and learning efficiency levels. In the cost efficiency stage, different types of expenses and investments are employed to support a given number of students, teachers and administrative staff. In the learning efficiency stage, these groups of individuals help to produce important outputs related to performance in student tests and school rankings. Results indicate that Australian public schools are heterogeneous. Policy implications are also discussed.     

What accounts for international differences in student performance? A re-examination using PISA data

We use the PISA student-level achievement database to estimate international education production functions. Student characteristics, family backgrounds, home inputs, resources, teachers and institutions are all significantly associated with math, science and reading achievement. Our models account for more than 85% of the between-country performance variation, with roughly 25% accruing to institutional variation. Student performance is higher with external exams and budget formulation, but also with school autonomy in textbook choice, hiring teachers and within-school budget allocations. Autonomy is more positively associated with performance in systems that have external exit exams. Students perform better in privately operated schools, but private funding is not decisive.     

THE EFFICIENCY IMPLICATIONS OF USING PROPORTIONAL EVALUATIONS TO SHAPE THE TEACHING WORKFORCE

We examine the efficiency implications of imposing proportionality in teacher evaluation systems. Proportional evaluations force comparisons to be between equally circumstanced teachers. We contrast proportional evaluations with global evaluations, which compare teachers to each other regardless of teaching circumstance. We consider a policy where administrators use teacher ratings to help shape the workforce and define efficiency in terms of student achievement. Our analysis shows that proportionality can be imposed in teacher evaluation systems without efficiency costs under a wide range of evaluation and estimation conditions. Proportionality is efficiency enhancing in some cases. These findings are notable given that proportional evaluations offer a number of other policy benefits. (JEL I20, J48)     

Individual teacher incentives and student performance

This paper is the first to systematically document the relationship between individual teacher performance incentives and student achievement using the United States data. We combine data from the National Education Longitudinal Survey on schools, students, and their families with our own survey conducted in 2000 regarding the use of teacher incentives. This survey on teacher incentives has unique data on frequency and magnitude of merit raises and bonuses, teacher evaluation, and teacher termination. We find that test scores are higher in schools that offer individual financial incentives for good performance. Moreover, the estimated relationship between the presence of merit pay in teacher compensation and student test scores is strongest in schools that may have the least parental oversight. The association between teacher incentives and student performance could be due to better schools adopting teacher incentives or to teacher incentives eliciting more effort from teachers; it is impossible to rule out the former explanation with our cross sectional data.     

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.     

EXAM SCHEDULING AND STUDENT PERFORMANCE

This paper uses data from a single School of a UK university to estimate the impact of a switch from end‐of‐semester to end‐of‐year final exams on student performance. The identification strategy exploits the fact that while the timing of final exams changed, the timing of mid‐term exams remained the same. Estimates are based on a difference‐in‐differences methodology that compares final and mid‐term exam scores after the switch, with final and mid‐term exam scores before the switch. The empirical findings suggest that the shift of final exams to the end of the academic year had a negative effect on student achievement. Many changes in higher education are often done on the basis of financial, administrative or ideological considerations, underestimating the magnitude of their effect on student learning and student performance.     

The Case of the Missing Organizations: Co-operatives and the Textbooks

The author discusses the following seven issues affecting assessment of undergraduates in universities: decisionmaking and the selection of tests, the use of written and oral assignments to measure learning, the characteristics of grades and portfolios for evaluating students, opportunities for self-assessment and feedback to instructors, retention of learning and the testing for higher-ordered thinking, the psychology of students in the economics classroom, and the development of new tests as public goods. The author suggests ways that economics faculty can add new dimensions to their assessment practices, improve their understanding of assessment choices, use assessment to enhance the quality of student thinking, and conduct research studies on assessment questions.     

Test scores,educational opportunities,and individual choice

A model combining student preferences for college with university admissions decisions is estimated to provide information on the role of test scores in the determination of post-secondary educational opportunities in the U.S. In contrast to implications of much of the recent criticism of tests and their use, we find that scholastic aptitude test scores are more strongly related to student application and choice of college ‘quality’ than to college admissions decisions. In addition, although there is a substantial correlation between test scores and high school performance, we find that both post-secondary school preferences and ultimate opportunities are related as much to performance in high school as to test scores themselves. Although SAT scores certainly exclude some persons from schools, our findings indicate that they do not represent an overriding constraint on the college opportunities of high school graduates.

SCHOOL DISCIPLINE: A SOURCE OR SALVE FOR THE RACIAL ACHIEVEMENT GAP?*

Racial disparities in school discipline are believed to contribute to the persistent achievement gap between black and white students. In this article, I estimate the relationship between school discipline and achievement within a structural model, taking into account the spillover effects of disruptive behavior. I find that discipline has an overall positive influence on student performance and that the racial gap in discipline stemming from cross‐school variation in discipline policies is consistent with achievement maximization. Integrating schools can close both the discipline and achievement gaps; however, overall achievement is reduced since schools are less able to target their discipline policies.     

How and Why Has Teacher Quality Changed in Australia?

International research suggests that differences in teacher performance can explain a large portion of student achievement. Yet little is known about how the quality of the Australian teaching profession has changed over time. Using consistent data on the academic aptitude of new teachers, we compare those who have entered the teaching profession in Australia over the past two decades. We find that the aptitude of new teachers has fallen considerably. Between 1983 and 2003, the average percentile rank of those entering teacher education fell from 74 to 61, while the average rank of new teachers fell from 70 to 62. We find that two factors account for much of the decline: a fall in average teacher pay (relative to other occupations) and a rise in pay differentials in non‐teaching occupations.     

India shining and Bharat drowning: Comparing two Indian states to the worldwide distribution in mathematics achievement

Increasing evidence suggests that the level and distribution of cognitive skills is more important to economic development than absolute measures of schooling attainment, and that income and skill inequality are inextricably linked. Yet for most of the developing world no internationally comparable estimates of cognitive skills exist. This paper uses student answers to publicly released questions from an international testing agency together with statistical methods from Item Response Theory to place secondary students from two Indian states—Orissa and Rajasthan—on a worldwide distribution of mathematics achievement. These two states fall below 43 of the 51 countries for which data exist. The bottom 5% of children rank higher than the bottom 5% in only three countries—South Africa, Ghana and Saudi Arabia. But not all students test poorly. Inequality in the test-score distribution for both states is next only to South Africa. The combination of India's size and large variance in achievement give both the perceptions that India is shining even as Bharat, the vernacular for India, is drowning. How India's development unfolds will depend critically on how the skill distribution evolves and how low- and high-skilled workers interact in the labor market.     

Selection on performance and tracking

Tracking is widely used in secondary schools around the world. Some countries put more emphasis on the use of performance to place students into tracks (e.g. the Netherlands), while in other countries parents have more influence on the track their child will go to (e.g. Germany). This article examines whether selection into tracks based on performance has an effect on the relation between tracking and student performance and educational opportunities. Using data from the Programme for International Student Assessment for around 185 000 students in 31 countries, different estimation models are compared. The results indicate that a highly differentiated system is best for performance when schools always consider prior performance when deciding on student acceptance. In systems with a few tracks, there is no such impact. Equality of opportunity is best provided for in a system with many tracks when schools always consider prior performance.
