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.     

Group incentives for teachers and their effects on student learning: a systematic review of theory and evidence

The effects of teachers’ group incentives on student achievement are examined by reviewing theoretical arguments and empirical studies published between 1990 and 2011. Studies from developing countries reported positive effects of group incentives on student test scores. However, experimental studies from developed countries reported insignificant effects. Some of the evidence appears to show a positive association between small group size of teachers and the effectiveness of group incentives. Still, it is uncertain whether the key to successful group incentives in teaching emanates from the incentive size, teacher group size, teacher intrinsic motivation, or type of incentive (rank type vs. non-rank type). Furthermore, most studies show that individual teacher incentives have positive effects unlike studies on group incentives. However, there is a lack of comparative studies of group incentives and individual incentives. We conclude that current empirical evidence has unclear policy implications and recommend additional experimental research.     

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.     

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 credentials and student achievement: Longitudinal analysis with student fixed effects

We use a rich administrative dataset from North Carolina to explore questions related to the relationship between teacher characteristics and credentials on the one hand and student achievement on the other. Though the basic questions underlying this research are not new—and, indeed, have been explored in many papers over the years within the rubric of the “education production function”—the availability of data on all teachers and students in North Carolina over a 10-year period allows us to explore them in more detail than has been possible in previous studies. We conclude that a teacher's experience, test scores and regular licensure all have positive effects on student achievement, with larger effects for math than for reading. Taken together the various teacher credentials exhibit quite large effects on math achievement, whether compared to the effects of changes in class size or to the socio-economic characteristics of students.     

Effects of teacher professional characteristics on student achievement: an investigation in blended learning environment with standards-based curriculum

Use of different teaching materials and curriculum for the same subjects is always a confounding factor in studies investigating teacher characteristics and student achievement. The purpose of this study is to understand the effects of different teacher qualities on student achievement in high schools with a standards-based curriculum delivered over a blended learning environment. Utilizing quantitative research approach, this study investigates the effects of teacher characteristics and teaching practices in a course offered through Cisco Networking Academy, which has a standards-oriented curriculum delivered online. Participants in the study were 226 teachers and 3299 students from Networking Academies located in the USA. The findings suggest that certain teacher characteristics such as teaching experience, degree, and primary teaching field do not have effects on student achievement.     

高质量教师的经济价值

以往关于教师质量的研究都止于教师质量对学生学业成绩的影响,而没有进一步分析高质量教师的经济价值。高质量的教师能够带来学生学业成绩的提高,而学业成绩所反映的认知技能能够在劳动力市场上获得收益。因此,将教师效能的研究结果与认知技能回报率的研究结果相结合,可以估算出高质量教师的经济价值。结果表明,一位高于平均水平以上一个标准差的教师如果教授20人的班级,一年之内该教师能够带来学生未来工资收入的现值增加40万美元。如果该教师所教的班级人数更多,那么他的年度边际经济价值更大。     

Effects of class size and adaptive teaching competency on classroom processes and academic outcome

In many studies of class size effects, teacher characteristics are missing, even though many argue it is not class size that is important but teacher quality. In the present study teachers' effectiveness on the learning progress was assessed while teaching a unit with predefined learning objectives. To measure adaptive teaching competency a multi-method approach was employed (e.g., vignette and video test). There were 49 teachers and 898 students. Smaller classes led to higher academic learning progresses, better knowledge of students, and better classroom processes. Adaptive teacher competency remained relevant in smaller classes, that is, class size and teacher quality were independently important.     

教师参与专业发展活动对学生学业成绩影响的实证研究——基于北京市高中学生的分析

教师专业发展是提高学校教育质量和学生学业成就的关键因素。关于教师专业发展的实证研究主要关注的是专业发展活动对教师本身的影响,较少有研究关注专业发展活动对学生带来的影响。本研究基于2016~2019年北京市高中阶段4万多名学生的标准化考试成绩和近2000名教师的问卷调查数据,采用增值模型分析教师对学生学业成绩的增值影响,并进一步聚焦教师参与区级和校本教研活动对学生学业成绩的影响。分析结果显示,教师参与区级教研活动的程度对学生成绩有显著的正向影响,其中聚焦于学科课程内容的教研活动对学生成绩的增值作用尤其显著。此外,教师参与校本教研活动的程度对学生成绩有显著的正向影响,其中教师之间的非正式交流的积极作用不容忽视。     

Meeting the highly qualified teachers challenge

The moulding of the future of a nation depends on the teachers and the education they provide in schools. Research evidence from the US. National Assessment of Educational Progress (NAEP) confirms this to be the case. Quantitative analysis of data indicates that measures associated with pre-service teacher preparation are by far the strongest correlates of student achievement (Darling-Hammond 2000). The research report of Wilson, Floden, and Ferrini-Mundy (2001) also suggests a strong relationship between teacher preparation and teacher effectiveness. Other research studies similarly indicate that differences in teacher quality are the most crucial for student achievement when compared with variables such as class size, streaming, or the amount of homework (Anderson & Helms 2001; Mendro 1998; Powell & Anderson 2002; Rivkin, Hanushek & Kain 2001; Saunders & Horn 1994; Strong & Tucker 2000) as possible contributory factors. In the pursuit of improved student achievement, we therefore need to examine seriously the role of teacher variables, ranging from teacher qualifications and their subject matter knowledge, to what motivates them to take up teaching as a career and as a consequence, how they teach in classrooms.     

Is traditional teaching really all that bad? A within-student between-subject approach

Recent studies conclude that teachers are important for student learning but it remains uncertain what actually determines effective teaching. This study directly peers into the black box of educational production by investigating the relationship between lecture style teaching and student achievement. Based on matched student-teacher data for the US, the estimation strategy exploits between-subject variation to control for unobserved student traits. Results indicate that traditional lecture style teaching is associated with significantly higher student achievement. No support for detrimental effects of lecture style teaching can be found even when evaluating possible selection biases due to unobservable teacher characteristics.     

Does teaching style explain differences in learner achievement in low and high performing schools in Kenya?

Quality of instructional delivery is an important determinant of the extent to which the teaching process has an impact on learning achievement. The literature identifies many contributors of learning achievement including teacher, curricula, teaching, student, home and school environments. On an ‘education production function’ approach, achievement may be modelled as an outcome determined by school and classroom based inputs. The processes of achievement determination are typically assumed, in the absence of detailed information about actual classroom practices. In Kenya, primary schools continue to report differentials in performance on standardized tests even when policy implementers distribute teachers normally to these schools. Such differences in academic performance have been reported even among schools within the same neighbourhood. Schools from the same neighbourhood draw students with similar backgrounds and expose them to teachers who have gone through the same training. This paper hypothesizes that teaching style plays a key role in explaining the differences in academic performance among students between primary schools. Using data from 72 math lessons that were filmed in 72 primary schools in Kenya, the authors demonstrate the extent to which teaching practice explains differences in performance among students and schools. While controlling for individual and school based factors, the paper uses mixed methods to analyse the linkages between teaching practices and learning achievement. The main research finding and policy implication is that students learning achievement can be improved through quality teaching, even when other conditions such as class size are not conducive.     

The gateway to the profession: Assessing teacher preparation programs based on student achievement

With teacher quality repeatedly cited as the most important schooling factor influencing student achievement, there has been increased interest in examining the efficacy of teacher training programs. This paper presents the results of research investigating the relationship between teachers who graduate from different training programs and student achievement on state reading and math tests. Using a novel methodology that allows teacher training effects to decay, we find that training institution indicators explain a statistically significant portion of the variation in student achievement in reading, but not in math. Moreover, there is evidence that graduates from some specific training programs are differentially effective at teaching reading than the average teacher trained out-of-state and that these differences are large enough to be educationally meaningful.     

Are class size differences related to pupils' educational progress and classroom processes? findings from the institute of education class size study of children aged 5–7 years

Abstract Despite evidence from the USA that children in small classes of less than 20 do better academically there is still a vociferous debate about the effects of class size differences in schools, and considerable gaps in our understanding of the effects of class size differences. This article summarises results from the most complete UK analysis to date of the educational consequences of class size differences. The study had two aims: first, to establish whether class size differences affect pupils’ academic achievement; and second, to study connections between class size and classroom processes, which might explain any differences found. The study had a number of features that were designed to be an improvement on previous research. It used an ‘observational’ approach, rather than an interventionist one, in order to capture the nature of the relationship between class size and achievement across the full range of observed classes, and it employed a longitudinal design with baseline assessment to adjust for possible non‐random selection of children into classes. The study followed a large sample of over 10,000 children from school entry through the infant stage, i.e. children aged 4–7 years. It used multilevel statistical procedures to model effects of class size differences while controlling for sources of variation that might affect the relationship with academic achievement, and a multimethod research approach, integrating teachers’ judgements and experiences with case studies, and also carefully designed time allocation estimates and systematic observation data. Results showed that there was a clear effect of class size differences on children's academic attainment over the (first) Reception year. In the case of literacy, the lowest attainers on entry to school benefited most from small classes, particularly below 25. Connections between class size and classroom processes were examined and a summary model of relationships presented. Effects were multiple, not singular; in large classes there are more large groups and this presented teachers with more difficulties, in smaller classes there was more individual teacher contact with pupils and more support for learning, and in larger classes there was more pupil inattentiveness and off‐task behaviour. Results support a contextual approach to classroom learning, within which class size differences have effects on both teachers and pupils. It is concluded that much will depend on how teachers adapt their teaching to different class sizes and that more could be done in teacher training and professional development to address contextual features like size of class.     

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.     

Understanding When Teachers Disagree about Student Disability

The persistent racial and ethnic disparities in special education in the United States raise concerns about the potential misidentification of students. While previous studies have focused on how various student and school factors influence teacher decisions, there is less attention on when teachers disagree about student disability or special education. The current study uses national data from the Educational Longitudinal Study of 2002 to examine when teachers disagreed in their perception of student disability for more than 10,000 high school students. A unique feature of the data is each student is observed in two different subject classrooms, providing an opportunity to examine how differences in student achievement, behavior, and teacher characteristics influence when teachers disagreed in their judgment of student disability. The results indicate that teachers were more likely to disagree when student behavior varied across classrooms, while differences in student achievement and teacher characteristics were not related to disagreement. The study also found that teachers disagreed more for students who were Black, male, and from lower socioeconomic backgrounds. The main findings highlight how disability is often a context-dependent social construct and have implications for how students are identified for special education.     

The cost-effectiveness of raising teacher quality

Econometric studies suggest that student achievement may be improved if high-performing teachers are substituted for low-performing teachers. Drawing upon a recent study linking teacher performance on licensure exams with gains in student achievement, an analysis was conducted to determine the cost-effectiveness of requiring teacher applicants to meet a minimum 1000 SAT test score requirement, while raising teacher salaries by 45 percent in order to maintain an adequate pool of candidates. Results indicate that the cost-effectiveness of this approach to raising teacher quality is substantially lower than the cost-effectiveness of a competing approach for raising student achievement, involving the implementation of systems that provide formative assessment feedback to students and teachers regarding student performance in math and reading. The implementation of formative assessment instead of less cost-effective approaches would help to achieve the important goal of raising math and reading achievement while using fewer resources. The savings in resources may then be used to achieve other important educational goals—those that are not well-addressed through formative assessment.     

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.     

Special education and subject teachers’ self‐perceived readiness to teach mathematics to low‐performing middle school students

Educational reforms during the last decade have led to a more inclusive environment for students with different needs and have placed demands on teachers’ readiness to instruct diverse students in the general classroom. Previous research has ascertained that student achievement is correlated with teacher quality and teachers’ efficacy beliefs. Today, basic competence in mathematics is more important than ever for managing routine day‐to‐day activities and therefore, identifying and educationally supporting students with low performance in mathematics is necessary. The aim of the study was to investigate the perceived teacher efficacy beliefs of special education and mathematics teachers when teaching mathematics to low‐performing middle school students. Results indicated that special education teachers had higher teacher efficacy beliefs than mathematics teachers. Teacher experience, certification or gender had no effect on teachers’ efficacy beliefs. Furthermore, subject teachers reported high pedagogical knowledge for teaching low‐performing students, and special education teachers reported having moderate mathematical subject knowledge.     

The effect of kindergarten classroom size reduction on second grade student achievement: Evidence from California

Because classroom size reduction (CSR) and standards based testing were implemented at the same time in California during the mid-1990s, it is difficult to isolate the effects of classroom size on outcomes from the effects of curriculum changes. As a result, the main comparison in this paper is very specific – the effect of reduced sized kindergarten classrooms on test performance in second grade. The main result of the paper is that the effect of classroom size reduction is small, especially when compared to the other determinants of student achievement at the second grade level. There is a very small effect of classroom size reduction on student achievement in reading and math, and no effect in language and spelling. Of the two offsetting effects of CSR controlling for spending – the direct effect of smaller classes and the indirect effect on teacher quality, the class-size effect is larger. Over time, the negative effect on teacher quality is reduced as new teachers gain experience and credentials.
