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.  相似文献

Pedagogical content knowledge (PCK) is a type of teacher knowledge to be developed by a teacher. PCK is said to contribute to effective teaching. Most studies investigated the development of PCK and its influence on students’ learning from the teachers’ perspectives. Only a limited number of studies have investigated the components of science teachers’ PCK that helped students’ learning from the perspective of students. Thus, it is the aim of this study to investigate the level of science teachers’ PCK from students’ perspective, in particular whether or not students of different achieving ability had different views of teachers’ PCK in assisting their learning and understanding. Based on the PCK research literature, six components of PCK have been identified, which were as follows: (1) subject matter knowledge, (2) knowledge of teaching strategies, (3) knowledge of concept representation, (4) knowledge of teaching context, (5) knowledge of students, and (6) knowledge of assessment in learning science. A questionnaire consisting of 56 items on a five-point Likert-type scale were used for data collection from 316 Form Four students (16 years old). One-way analysis of variance revealed that the differences in science teachers’ PCK identified by students of different achieving abilities were statistically significant. Overall, students of various academic achieving abilities considered all the components of PCK as important. The low-achieving students viewed all the components of PCK as being less important compared to the high and moderate achievers. In particular, low-achieving students do not view ‘knowledge of concept representation’ as important for effective teaching. They valued the fact that teachers should be alert to their needs, such as being sensitive to students’ reactions and preparing additional learning materials. This study has revealed that PCK of science teachers should be different for high and low-achieving students and knowledge of students’ understanding plays a critical role in shaping teachers PCK.  相似文献

Attributions can have a significant effect on academic achievement and students with learning difficulties are more likely to display negative attributions than their peers. In this article, the attributions of students identified as having learning difficulties are compared with those of other non-labelled low achievers, and non-labelled average achievers. Margaret Banks, MSc research methods student, and Dr Lisa Woolfson, Reader in Educational Psychology, both at the University of Strathclyde, involved 26 low-achieving students (15 identified as having learning difficulties and 11 without any such label) and 27 averagely achieving students in their exploratory study. The students attempted to solve two sets of puzzles that, unknown to the participants, were actually impossible. They then gave a reason for their failure and rated the stability and controllability of their failure. Participants were also asked to give a self-rating of academic achievement. It was found that teacher and student perceptions of academic achievement were not synonymous. In terms of attributions, Margaret Banks and Lisa Woolfson argue that teachers' perceptions of student achievement may not be as important as students' self concept. They suggest that low self-perception of achievement and negative attributions are both associates of low self-esteem.  相似文献

This paper identifies the amount of variance in mathematics achievement in high- and low-achieving schools that can be explained by school-level factors, while controlling for student-level factors. The data were obtained from 2679 Iranian eighth graders who participated in the 2007 Trends in International Mathematics and Science Study. Of the total sample, 1422 and 1257 students were from high- and low-achieving schools, respectively. Two-level hierarchical linear modelling was applied. The results indicated that of the total variance in mathematics achievement, 27.95 and 6.70% were due to between-school differences in the high- and low-achieving schools, respectively. Controlling for the school-level factors, the better-performing students were those with a higher level of confidence in learning mathematics in both samples. After controlling for the student-level factors, inadequacies in school resources and school type yielded the strongest link to achievement in the high- and low-achieving schools, respectively.  相似文献

Effective schools should be superior in both enhancing students’ achievement levels and reducing the gap between high- and low-achieving students in the school. However, the focus has been placed mainly on schools’ achievement levels in most school effect studies. In this article, we focused our attention upon the school-specific achievement dispersion as well as achievement level in determining effective schools. The achievement dispersion in a particular school can be captured by within-school variance in achievement (σ2). Assuming heterogeneous within-school variance across schools in hierarchical modeling, it is possible to identify school factors related to high achievement levels and a small gap between high- and low-achieving students. By analyzing data from the TIMMS-R, we illustrated how to detect variance heterogeneity and how to find a systematic relationship between within-school variance and school practice. In terms of our results, we found that schools with a high achievement level tended to be more homogeneous in achievement dispersion, but even among schools with the same achievement level, schools varied in their achievement dispersion, depending on classroom practices.  相似文献

The goal of this study is to characterize the patterns of teachers’ beliefs regarding low-achieving students and instruction of higher order thinking. Subjects are 40 Israeli teachers. Results show that 45% of the teachers believe that higher order thinking is inappropriate for low-achieving students. Findings suggest that teachers’ beliefs in this context are related to their general theory of instruction: viewing learning as hierarchical in terms of students’ academic level was found to be related to a traditional view of learning, i.e., seeing learning as progressing from simple, lower order cognitive skills to more complex ones. Implications for teacher education are discussed.  相似文献

Many children have significant mathematical learning disabilities (MLD, or dyscalculia) despite adequate schooling. The current study hypothesizes that MLD partly results from a deficiency in the Approximate Number System (ANS) that supports nonverbal numerical representations across species and throughout development. In this study of 71 ninth graders, it is shown that students with MLD have significantly poorer ANS precision than students in all other mathematics achievement groups (low, typically, and high achieving), as measured by psychophysical assessments of ANS acuity (w) and of the mappings between ANS representations and number words (cv). This relation persists even when controlling for domain-general abilities. Furthermore, this ANS precision does not differentiate low-achieving from typically achieving students, suggesting an ANS deficit that is specific to MLD.  相似文献

Many school accountability programs are built on the premise that the sanctions attached to failure will produce higher future student achievement. Furthermore, such programs often include subgroup achievement rules that attempt to hold schools accountable for the performance of all demographic classes of students. This paper looks at two issues: the degree to which such rules increase the likelihood of school failure, and the effect of failure to meet a performance standard on subsequent student achievement. Using data from California's state accountability program, I find that subgroup rules lead to otherwise similar schools having different probabilities of failure. I also find that subgroup induced failure leads to lower future student achievement under both the state's system and its’ implementation of No Child Left Behind. This implies that small demographic differences play a large role in how schools are judged and how they perform under current accountability systems.  相似文献

The aim of this study is to compare the characteristics and sources of students’ mental models of acids and bases with a teacher’s anticipations and, based on this comparison, to explore some possible explanations why motivated students might fail to learn from a subject‐knowledgeable chemistry teacher. The study involves a chemistry teacher and her 38 ninth graders and focuses on the mental models of three high achievers and three low achievers who were interviewed in depth. Four students’ mental models of acid and base are identified. The mental models and sources of students’ conceptions of acids and bases that influenced the high achievers are compared to those of the low achievers. We find that the teacher in the study made accurate anticipations of her students’ mental models in the case of the high achievers but inaccurate anticipations of the low‐achievers’ mental models and the diverse sources influencing their mental models. In addition, the teacher incorrectly attributed the poor achievement of the low‐achieving students to their intuition and underestimated the effects of her teaching on the achievement of these students. As a result, the teacher’s instruction reinforced the low‐achievers’ incorrect mental models. Finally, the different approaches for teaching students with different achievements are emphasized according to the empirical data in this study.  相似文献

Mean or median student growth percentiles (MGPs) are a popular measure of educator performance, but they lack rigorous evaluation. This study investigates the error in MGP due to test score measurement error (ME). Using analytic derivations, we find that errors in the commonly used MGP are correlated with average prior latent achievement: Teachers with low prior achieving students have MGPs that underestimate true teacher performance and vice versa for teachers with high achieving students. We evaluate alternative MGP estimators, showing that aggregates of SGP that correct for ME only contain errors independent of prior achievement. The alternatives are thus more fair because they are not biased by prior mean achievement and have smaller overall variance and larger marginal reliability than the Standard MGP approach. In addition, the mean estimators always outperform their median counterparts.  相似文献

Based on the Trends in International Mathematics and Science Study 2007 study and a follow-up national survey, data for 3,901 Taiwanese grade 8 students were analyzed using structural equation modeling to confirm a social-relation-based affection-driven model (SRAM). SRAM hypothesized relationships among students’ perceived social relationships in science class and affective and cognitive learning outcomes to be examined. Furthermore, the path coefficients of SRAM for high- and low-achieving subgroups were compared. Given the 2-stage stratified clustering design for sampling, jackknife replications were conducted to estimate the sampling errors for all coefficients in SRAM. Results suggested that both perceived teacher–student relationships (PTSR) and perceived peer relationships (PPR) exert significant positive effects on students’ self-confidence in learning science (SCS) and on their positive attitude toward science (PATS). These affective learning outcomes (SCS and PATS) were found to play a significant role in mediating the perceived social relationships (PTSR and PPR) and science achievement. Further results regarding the differences in SRAM model fit between high- and low-achieving students are discussed, as are the educational and methodological implications of this study.  相似文献

Using statewide data from Florida, we analyze the impact of both pre-service and in-service training on the ability of teachers to promote academic achievement among students with disabilities. We find students with disabilities whose teacher is certified in special education have greater achievement in both math and reading than similar students whose teacher is not special-education certified. However, students without disabilities experience slightly lower achievement when taught by a special-education certified teacher. In-service professional development has no effect on the value-added of teachers in special education courses, but non-disabled students whose regular education teachers received special education training exhibit modestly higher achievement. Similarly, the gain in effectiveness associated with teacher experience is greater for teachers of regular education courses than for teachers of special education courses. Teachers with advanced degrees are more effective in boosting the math achievement of students with disabilities than are those with only a baccalaureate degree.  相似文献

Australian teacher education programmes that prepare teachers of English to speakers of other languages (TESOL) are confronting the nexus of two facets of globalization: transformations in the Asian region, captured in the notion of the “Asian century”, and shifting conceptions of professionalism in TESOL in non-compulsory education. In booming Asian economies, English language learning is integral to the demand for high-quality education. This has produced increases in TESOL Teacher Education Programme (TTEP) enrolments of both domestic Australian students and international students from Asia. Growth in demand for TTEPs has necessitated that they cater to student diversity, and the intended contexts of practice. This demand has coincided with a concurrent movement towards professional standards for TESOL that, we argue, confronts complexities around quality, accountability, and professional identity and achieving conceptual and contextual coherence. Drawing on discourses of managerialism and performativity, this paper explores tensions between increased student demands for TTEPs, professional standards discourses which are part of the global policy discourses on teacher quality, and the achievement of programmatic conceptual and contextual coherence from the perspective of Australian TTEPs.  相似文献

Over the last decade many districts implemented performance pay incentives to reward teachers for improving student achievement. Economic theory suggests that these programs could alter teacher work effort, cooperation, and retention. Because teachers can choose to work in a performance pay district that has characteristics correlated with teacher behavior, I use the distance between a teacher's undergraduate institution and the nearest performance pay district as an instrumental variable. Using data from the 2003 and 2007 waves of the Schools and Staffing Survey, I find that teachers respond to performance pay incentives by working fewer hours per week. Performance pay also decreases participation in unpaid cooperative school activities, while there is suggestive evidence that teacher turnover decreases. The treatment effects are heterogeneous; male teachers respond more positively than female teachers. In Florida, which restricts state performance pay funding to individual teachers, I find that work effort and teacher turnover increase.  相似文献

This paper reports on findings from a large sample survey in the states of India that account for two thirds of the children out of school. It then examines the feasibility of the central government's goals to ensure all children complete 5 years of school by 2007, and 8 years by 2010. These goals—more ambitious than the global EFA goals—are unlikely to be achieved without significant reforms by the central and state governments. It examines key reform options: in the public spending pattern; improving teacher accountability and work environment; incentives to improve demand for schooling; and the private sector. It argues that central to universalising elementary education will be improving the level, equity and efficiency of public spending. However, even with these reforms, improving teacher accountability will still remain key to the achievement of the goals.  相似文献

This study contributes to the literature by examining the evolution of socio-economic disparities in literacy skills between age 15 and 27. It uses combined cross-sectional data from the Programme for International Student Assessment and the Programme for the International Assessment of Adult Competencies in 20 countries and adopts a synthetic cohort approach. In the article we examine if there are differences in the evolution of socio-economic disparities in literacy between the teenage years and young adulthood among high-achieving students (90th percentile) and among low-achieving students (10th percentile) and compare differences across education systems. We used parental education as an indicator of socio-economic status. Findings indicate that on average, disparities in literacy skills observed at age 15 widen by 15% of a standard deviation by age 27. Such increase is determined by a more pronounced growth in achievement among individuals with tertiary educated parents than among individuals whose parents did not complete tertiary education. The increase in socio-economic gaps between age 15 and 27 is more pronounced among low-achieving students. The group that improves the most between age 15 and 27 is low-achieving individuals with tertiary educated parents. We find that socio-economic differences in educational attainment, NEET status and use of skills at home and in the workplace explain a large part of socio-economic disparities in literacy achievement among young adults. Although countries with above-average disparities at age 15 tend to also display above-average disparities at age 27, we identify differences across countries.  相似文献

Developing a high level of efficacy can be challenging to teachers who work with low-achieving students. The authors adopted a pragmatic qualitative research design to investigate the sources of efficacy information reported by five high-efficacy teachers and four low-efficacy teachers of secondary low-achieving students in Singapore. The results show that the psychological sources of information postulated by Albert Bandura (i.e., mastery experiences, verbal persuasion, vicarious experience, and physiological and emotional arousal), are valid but insufficient to explain high teacher efficacy. Three additional nonpsychological sources of information, including teachers' knowledge about students, rapport with students, and previous working experiences, also played significant roles in the creation of high teacher efficacy.  相似文献

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.  相似文献

This article reports on a naturalistic study conducted with 24 low-achieving high school Biology students. Observations and interviews were used to determine how the teacher and students used two different computer-based instructional programs on frog anatomy and dissection, and how students conducted a subsequent dissection. Student and teacher opinions were solicited about the different computer-based programs and the dissection laboratory. Findings suggest that dissection can be a valuable learning experience for low-achieving Biology students when they are engaged in group cooperation and interaction and receive adequate instructional preparation. Results also point to the motivation these students exhibit toward computer use, to the importance of balancing learner and program control, and to the value of considering the teacher as a possible source of both interaction and structure during courseware use. Recommendations based on these and other findings are offered for educators and instructional developers.

International benchmarking and national testing of students at all levels of schooling have provoked teachers to critically reflect on their place in this endeavour. Many of the curriculum and pedagogical approaches associated with this type of assessment and accountability conflict with long-held beliefs about the role of teachers and the work of schooling. Singapore is recognised for significant achievement in the international schooling arena and also has a long history of national testing. This study draws specifically on positioning theory to investigate teacher beliefs and positioning in these times. A large qualitative research project located in Singapore sought the ways experienced teachers positioned themselves and their work as they negotiated multiple and sometimes conflicting discourses of teaching. A rigorous process was used to elicit teacher beliefs and resultant teacher positions.  相似文献
