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.     

Perceived Classroom Control,Self-Regulated Learning Strategies,and Academic Achievement

Relations between perceived classroom control, self-regulation strategies and academic achievement were investigated in a sample of 302 sixth grade students. Four distinct perceived classroom control styles were determined, based on the balance between teacher and student control over learning. It was hypothesised that student mathematics achievement would be contingent on the combined effects of teacher and student control: it would be highest when both teacher and student control is high, and would be lowest when both of them are low. Student adoption of self-regulated learning strategies would be linked to the net effect of student control: they would be highest when student control is high and teacher control is low, and would be lowest when teacher control is high and student control is low. The data tended to support these hypotheses, indicating that both achievement and self-regulation strategies were contingent on classroom processes.     

School quality and learning gains in rural Guatemala

I use unusually detailed data on schools, teachers and classrooms to explain student achievement growth in rural Guatemala. Several variables that have received little attention in previous studies – including the number of school days, teacher content knowledge and pedagogical methods – are robust predictors of achievement. A series of decompositions by student ethnicity and type of school shed some additional light on important questions in the Guatemalan context, and beyond. The large indigenous test score gap is not explained by differences in an extensive list of observable features of schools. The large effect for community characteristics suggests peer group effects or more general institutional differences related to services or labor markets. PRONADE community schools are associated with moderate gains vis-à-vis public schools in areas related to utilization of capacity, such as days worked. But these gains are largely offset by lower teacher capacity, which highlights the challenge of improving school quality in poor, rural areas.     

Child effortful control,teacher–student relationships,and achievement in academically at-risk children: Additive and interactive effects

The joint contributions of child effortful control (using inhibitory control and task accuracy as behavioral indices) and positive teacher–student relationships at first grade on reading and mathematics achievement at second grade were examined in 761 children who were predominantly from low-income and ethnic minority backgrounds and assessed to be academically at-risk at entry to first grade. Analyses accounted for clustering effects, covariates, baselines of effortful control measures, and prior levels of achievement. Even with such conservative statistical controls, interactive effects were found for task accuracy and positive teacher–student relationships on future achievement. Results suggest that task accuracy served as a protective factor so that children with high task accuracy performed well academically despite not having positive teacher–student relationships. Further, positive teacher–student relationships served as a compensatory factor so that children with low task accuracy performed just as well as those with high task accuracy if they were paired with a positive and supportive teacher. Importantly, results indicate that the influence of positive teacher–student relationships on future achievement was most pronounced for students with low effortful control on tasks that require fine motor skills, accuracy, and attention-related skills. Study results have implications for narrowing achievement disparities for academically at-risk children.     

Class Size and Teacher Quality

The `Vinson Report' on Public Education in NSW has become received wisdom. The report's recommendation on class sizes has attracted more attention than any other. This is unfortunate because it is on this issue that the Report is weakest. A thorough appraisal of the research on class sizes reveals that many studies have methodological problems that make their application in a real world context doubtful; many studies have introduced other reforms such as curriculum changes at the same time as class size reduction, making their individual effects impossible to determine; the large majority of studies have found no significant effects of class size on student achievement, while the remainder have shown small benefits, usually only when classes have less than 20 students; class size has less effect when teachers are competent; and the single most important influence on student achievement is teacher quality. Research shows unequivocally that it is far more valuable, both in educational and fiscal terms, to have good teachers than lots of teachers. It must be ensured that the current and incoming teaching force is the best it can be, before seeking to expand it.Key Words: child development, class size, public education, student achievement, teacher quality, teaching methods     

BOOK REVIEW. Development Planning and School Improvement for Middle Managers Co-authors: Marilyn Leask and Ian Terrell,London, UK: Kogan,Page 1997.x + 246 pp. ISBN 0 7494 2038 3

The longitudinal impacts on school change and student achievement of implementing varied Comprehensive School Reform (CSR) models was investigated in 12 elementary schools in diverse geographic locations. Each school was individually matched and compared to a demographically similar control school on measures of school climate, teacher satisfaction, observed classroom teaching methods, and student achievement on a battery of 4 individually administered reading tests. Data were analyzed for all CSR-control school pairs combined and separately for pairs representing 4 different CSR models (Balanced Early Literacy Initiative, Core Knowledge, Direct Instruction, and Success for All). Although results varied across location (rural versus urban) and models on different measures, overall CSR advantages were evidenced for teacher attitudes, school climate, and student achievement. Observations of teaching strategies further revealed their general conformity to the CSR models' pedagogical emphases (e.g., direct instruction, ability grouping, higher order questioning). The implications of the findings are discussed relative to processes of enacting and sustaining educational change using whole-school reform approaches.     

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.     

Multilevel Effects of Student and Classroom Factors on Elementary Science Achievement in Five Countries

This study examined the effects of individual student factors and classroom factors on elementary science achievement within and across five countries. The student‐level factors included gender, self‐confidence in science and home resources. The classroom‐level factors included teacher characteristics, instructional variables and classroom composition. Results for the USA and four other countries, Singapore, Japan, Australia and Scotland, were reported. Multilevel effects were examined through Hierarchical Linear Modelling, using the Trends in International Mathematics and Science Study 2003 fourth grade dataset. Overall, the results showed that selected student background characteristics were consistently related to elementary science achievement in countries investigated. At the student level, higher levels of home resources and self‐confidence and at the classroom level, higher levels of class mean home resources yielded higher science scores on the TIMSS 2003. In general, teacher and instructional variables were minimally related to science achievement. There was evidence of positive effects of teacher support in the USA and Singapore. The emphasis on science inquiry was positively related to science achievement in Singapore and negatively related in the USA and Australia. Recommendations for practice and policy were discussed.     

Research Findings from the Tennessee Value-Added Assessment System (TVAAS) Database: Implications for Educational Evaluation and Research

The Tennessee Value-Added Assessment System determines the effectiveness of school systems, schools, and teachers based on student academic growth over time. An integral part of TVAAS is a massive, longitudinally merged database linking students and student outcomes to the schools and systems in which they are enrolled and to the teachers to whom they are assigned as they transition from grade to grade. Research conducted utilizing data from the TVAAS database has shown that race, socioeconomic level, class size, and classroom heterogeneity are poor predictors of student academic growth. Rather, the effectiveness of the teacher is the major determinant of student academic progress. Teacher effects on student achievement have been found to be both additive and cumulative with little evidence that subsequent effective teachers can offset the effects of ineffective ones. For these reasons, a component linking teacher effectiveness to student outcomes is a necessary part of any effective educational evaluation system.     

Teacher and Classroom Context Effects on Student Achievement: Implications for Teacher Evaluation

The Tennessee Value-Added Assessment System (TVAAS) has been designed to use statistical mixed-model methodologies to conduct multivariate, longitudinal analyses of student achievement to make estimates of school, class size, teacher, and other effects. This study examined the relative magnitude of teacher effects on student achievement while simultaneously considering the influences of intraclassroom heterogeneity, student achievement level, and class size on academic growth. The results show that teacher effects are dominant factors affecting student academic gain and that the classroom context variables of heterogeneity among students and class sizes have relatively little influence on academic gain. Thus, a major conclusion is that teachers make a difference. Implications of the findings for teacher evaluation and future research are discussed.     

Pygmalion effects in the classroom: Teacher expectancy effects on students' math achievement

According to the Pygmalion effect, teachers' expectancies affect students' academic progress. Many empirical studies have supported the predictions of the Pygmalion effect, but the effect sizes have tended to be small to moderate. Furthermore, almost all existing studies have examined teacher expectancy effects on students' achievement at the student level only (does a specific student improve?) rather than at the classroom level (do classes improve when teachers have generally high expectations of their students?). The present study scrutinized the Pygmalion effect in a longitudinal study by using a large sample in regular classrooms and by differentiating between two achievement outcomes (grades and an achievement test) and two levels of analyses (the individual and classroom levels). Furthermore, students' self-concept was studied as a possible mediator of the teacher expectancy effect on achievement. Data come from a study with 73 teachers and their 1289 fifth-grade students. Multilevel regression analyses yielded three main results. First, Pygmalion effects were found at the individual level for both achievement outcomes. Second, multilevel mediation analyses showed that teacher expectancy effects were partly mediated by students' self-concept. Third, teachers' average expectancy effects at the class level were found to be nonsignificant when students' prior achievement was controlled.     

Teachers’ self-efficacy beliefs for teaching math: Relations with teacher and student outcomes

Social cognitive theory posits that teacher self-efficacy beliefs should be related to not only their own well-being outcomes but also classroom processes and student outcomes in the general ecology of the classroom environment. However, little research has directly examined the associations of teachers’ self-efficacy beliefs with these teacher and student-level outcomes simultaneously. The present study proposes and tests an integrative model of the relations of teachers’ self-efficacy for teaching math with their job satisfaction and student math achievement both directly and indirectly via interaction quality as a critical dimension of the quality of classroom processes. Additionally, student level relational and motivational predictors of math achievement, including individual perceptions of student-teacher interaction quality and math self-concept, are included per the ecology of the classroom environment. Based on data from over 6000 4th grade students and 450 teachers, results of multilevel structural equation modeling revealed that teachers’ self-efficacy beliefs for teaching math were positively associated with teachers’ job satisfaction and class levles of math achievement and interaction quality. At the individual student level, individual levels of math self-concept were positively associated with math achievement, and individual perceptions of interaction quality were positively associated with math self-concept. However, a negative association between residualized interindividual perceptions of interaction quality and math achievement was observed.     

Social capital and student learning: Empirical results from Latin American primary schools

This paper presents an empirical analysis of the relationship between social capital and student math and language achievement and the probability of promotion, using data gathered from fourth grade classrooms in public schools in four Latin American cities. The results suggest that social capital among teachers in a school, between teacher and students, and among the students in a classroom contribute significantly to learning achievement and the probability of promotion. Furthermore, social capital between the students matters at least as much as the teacher's social capital. Children learn from each other and the networks allowing that to happen can be very important. The current pressure on teachers to achieve results on reading and math scores has tended to push teachers to “teach to the test”. Ironically, this study's results indicate that spending time in creating social capital within the classroom environment is associated with higher language and math test scores.     

Estimating peer effects in Swedish high school using school,teacher, and student fixed effects

In this paper I use a rich dataset in order to observe each student in different subjects and courses over time. Unlike most peer studies, I identify the peers and the teachers that each student has had in every classroom. This enables me to handle the simultaneity and selection problems, which are inherent in estimating peer effects in the educational production function. I use a value-added approach with lagged peer achievement to avoid simultaneity and extensive fixed effects to rule out selection. To be specific, it is within-student across-subject variation with additional controls for time-invariant teacher characteristics that is exploited. Moreover, I identify students that are attending classes in which they have no peers from previous education which otherwise might bias the result. I find positive peer effects for the average student but also that there is a non-linear dimension. Lower-achieving students benefit more from an increase in both mean peer achievement and the spread in peer achievement within the classroom than their higher-achieving peers.     

Teacher effects on student achievement in first grade: which aspects matter most?

The present study investigates the effects of teachers (background qualifications, attitudes and beliefs, and instructional practices) on student achievement in mathematics, reading, and spelling in 1st grade. Its theoretical framework and methodology are based on recent work by Palardy and Rumberger (2008). Data from the SiBO Project, a longitudinal study in Flemish primary education, were analyzed for the present study using 2-level regression analysis. The results showed that teacher background had the largest effect on mathematics achievement, whereas instructional practices had the largest effects on both reading and spelling achievement. Moreover, the size of teacher effects depended upon the specific learning domain: Larger teacher effects were found for mathematics than for spelling and reading. Overall, the results suggest that teachers had a modest to strong effect on student achievement in first grade.     

The economic value of higher teacher quality

Most analyses of teacher quality end without any assessment of the economic value of altered teacher quality. This paper combines information about teacher effectiveness with the economic impact of higher achievement. It begins with an overview of what is known about the relationship between teacher quality and student achievement. This provides the basis for consideration of the derived demand for teachers that comes from their impact on economic outcomes. Alternative valuation methods are based on the impact of increased achievement on individual earnings and on the impact of low teacher effectiveness on economic growth through aggregate achievement. A teacher one standard deviation above the mean effectiveness annually generates marginal gains of over $400,000 in present value of student future earnings with a class size of 20 and proportionately higher with larger class sizes. Alternatively, replacing the bottom 5-8 percent of teachers with average teachers could move the U.S. near the top of international math and science rankings with a present value of $100 trillion.     

Teacher behavior and student outcomes: Results of a European study

This study investigates the extent to which the factors included in the dynamic model of educational effectiveness are associated with student achievement gains in six different European countries. At classroom level, the dynamic model refers to eight factors relating to teacher behavior in the classroom: orientation, structuring, questioning, teaching-modeling, application, management of time, teacher role in making classroom a learning environment, and classroom assessment. This paper presents results concerned with the impact of the teacher factors on student achievement. In each participating country (i.e., Belgium/Flanders, Cyprus, Germany, Greece, Ireland, and Slovenia), a sample of at least 50 primary schools (n?=?334) was drawn. Written tests in mathematics and science were administered to all grade 4 students (n?=?10,742) at the beginning and at the end of the school year 2010–2011. Students were also asked to complete a questionnaire concerning the eight teacher factors of the dynamic model. Structural equation modeling techniques were used to test the construct validity of the student questionnaire. Both across and within country analyses revealed that student ratings are reliable and valid for measuring the functioning of the teacher factors included in the dynamic model. Multilevel analyses revealed that teacher factors are associated with student achievement gains in mathematics and science. Implications for the development of educational effectiveness research and for improving quality of teaching are drawn.     

Teacher–student relationship quality and math achievement: The mediating role of teacher self-efficacy

The relation between social dyadic variables such as teacher–student relationship quality (TSRQ) and student achievement have been well-documented within prior work; however, less research has focused on how TSRQ associates with achievement. We used longitudinal structural equation modeling to investigate the extent that teacher self-efficacy mediated the relationship between TSRQ and math achievement for 881 children in the National Institute of Child Health and Human Development Study. Teacher–student closeness had moderate to large positive effects on teacher self-efficacy, whereas teacher–student conflict had small to moderate negative effects on teacher self-efficacy, which then had small positive effects on math achievement. Closeness only had indirect effects on math achievement via teacher self-efficacy, whereas conflict had direct and indirect effects on math achievement. The results were consistent across grades, lending strength to the findings. This study provides researchers and practitioners evidence of an area that can be developed to potentially enhance student success in math.     

The distribution of pedagogical content knowledge in Cambodia: Gaps and thresholds in math achievement

Increasing teacher quality is a major objective of recent Cambodian education policy. In mathematics education literature, pedagogical content knowledge (PCK) has emerged as a critical component of teacher quality that is strongly linked to student achievement. In this study I use data from a large survey of Cambodian schools to investigate the effect of math teachers’ PCK on third grade student achievement. I use ordinary least squares and Quantile Regression analyses to examine this aspect of teacher quality. I find that pedagogical knowledge is a strong predictor of student math achievement in Cambodia in comparison to other student, school, and background variables, but that the effect is concentrated among higher achieving students. Quantile Regression with this dataset also exposes gaps and thresholds in achievement associated with other explanatory variables. In addition, I investigate the proportional distribution of teacher PCK in Cambodia and find that lower quality teachers are more likely to be teaching lower achieving students of lower socioeconomic status.     

The relation between teacher self-reported individualization and student-perceived teaching quality in linguistically heterogeneous classes: an exploratory study

Germany historically responded to student diversity by tracking students into different schools beginning with grade 5. In the last decades, sociopolitical changes, such as an increase in “German-as-a-second-language” speaking students (GSL), have increased diversity in all tracks and have forced schools to consider forms of individualization. This has opened up the scientific debate in Germany on merits and limitations of individualization for different student groups within a tracked system and heterogeneous classes. The aim of the present exploratory study was to examine how individualized teaching (i.e., teacher self-reported individualized teaching practices and individual reference norm orientation) is related to student-perceived teaching quality. Additionally, we considered moderation effects of classroom composition in relation to achievement and proportion of GSL students. Longitudinal data came from 35 mathematics classes with 659 9th and 10th grade students. Results showed significant relation between teacher self-reported individualized teaching practices and individual reference norm orientation and monitoring. Regarding the composition effects, the proportion of GSL students in class moderated the relation between teacher self-reported individual reference norm orientation and cognitive activation. Our findings contribute to the growing body of evidence that classroom composition can differentially impact the relation between teachers’ behaviors and students’ perceptions of teaching quality.
