中学生课外补习时间投入对学业成绩的影响——基于PISA2015我国四省市数据的实证研究

基于PISA2015中国四省市数据,采用多层线性模型,研究中学生各科课外补习时间投入对学业成绩的影响效应.研究发现:课外补习时间与学业成绩之间存在先降后升的非线性关系,表明学科补习具有门槛效应,当补习时间超出某个阈值,学业成绩才会出现质的提升;数学补习时间投入差异扩大了不同家庭背景学生间数学成绩的差距,会造成教育结果的不均等;校内课程时间对学生成绩的影响呈先升后降的非线性关系,相较于补习时间,校内课程时间能更有效地提升学生成绩.因此,中学生及家长应基于实际的补习需求,合理投入补习时间;学校应保证学生校内课程学习时间,发挥学校教育的主导作用;政府应重视课外补习对教育公平的冲击,加强对校外培训机构的监管,还要为经济困难家庭学生提供必要的课外补习机会,缩小因课外补习带来的教育结果不均等,努力促进校内外教育公平.     

Developing and validating an instrument measuring school leadership

In this study, we developed and validated an instrument that researchers can use to measure the collective effort of principals and teachers who excise their own unique leadership to generate (integrated) school leadership. Based on 644 teachers, we found sound psychometric properties of the scales of the instrument and the instrument as a whole. We also explored the predictive properties of the instrument in predicting student achievement at the school level. Based on 53 schools, we found that the instrument can indeed measure the kind of school leadership that really matters to student achievement. When predicting student achievement (at the school level), the instrument tends to be more sensitive to more difficult school subjects (e.g. mathematics), implying that improvement in school leadership would lead to larger improvement in student achievement (at the school level) in more difficult school subjects.     

Teacher support,instructional practices,student motivation,and mathematics achievement in high school

The authors examined the relationships among teacher classroom practices, student motivation, and mathematics achievement in high school. The data for this study was drawn from the base-year data of High School Longitudinal Study of 2009. Structural equation modeling method was used to estimate the relationships among variables. The results indicate that conceptual teaching positively affected student mathematics achievement, whereas procedural emphasis in mathematics instruction had a negative effect. Teacher support influenced student mathematics achievement indirectly through students' mathematics self-efficacy, and also influenced students' interest in mathematics courses. Finally, students with higher levels of family socioeconomic status and prior achievement were more likely to have teachers who use conceptual teaching strategies. Students with higher prior achievement were also more likely to perceive higher levels of teacher support. The findings have theoretical and practical implications.

Social relations as predictors of achievement in math in Kenyan primary schools

In sub-Saharan Africa, where there is limited financial and human capital, it is important to examine how social relationships may serve to promote or undermine human capital formation. However, little is known about the contributions of social relations to human capital development, especially in terms of academic achievement in Africa. This study examined how variations in key aspects of social relations among teachers; between teachers and students; between principals, teachers, parents and students affect achievement in mathematics among sixth graders in 70 schools in six districts in Kenya. We modeled mathematics achievement as a function of measures of social perception and support while adjusting for school-, classroom- and student level background characteristics. We found that net of teacher subject knowledge and background characteristics, teachers who display commitment to teaching by always correcting homework and keeping students engaged during math lessons had their students performing better. Teacher absenteeism and lack of interest in teaching were negatively associated with performance in math. Lack of parental involvement in the classroom also had negative effects on grades. At the school level, the level of engagement of the principal, measured by supervision of teachers and good interpersonal interactions with parents had positive effects on math achievement. Schools where parents provided material and financial support had better grades, while student delinquency and absenteeism negatively affected grades.     

Evaluation of Broward County Alliance of Quality Schools Project

This article examines the evaluation of the Alliance of Quality Schools project, a 5-year project focusing on at-risk students in Broward County, Florida. The purpose of the evaluation was to determine the effect that the project had on selected academic and behavioral student indicators after its 5th year of implementation. This article focuses only on the findings related to the effect that the project has had on reading performance. Findings related to mathematics performance and student behavior can be found by reviewing the 5th-year evaluation report (Ligas, 1999). The project's mission, based on the philosophy that all children can learn, is to help the greatest number of at-risk students achieve at their highest performance level. In addition to a strong emphasis on Direct Instruction (DI), the Alliance of Quality Schools (AQS) initiative utilizes Accelerated Reader and Computer Assisted Instruction. The project has been evaluated yearly, from the 1994-1995 school year to the 1998-1999 school year. Fifth-year evaluation findings related to student achievement indicated that the effect of the project on academic achievement for elementary and middle school students enrolled at the Alliance schools has varied by grade level and year. The highest increases in student performance occurred at the 4th-grade level for reading and at the 5th-grade level for mathematics. These increases seem to be closely aligned to the grade levels targeted for school accountability by the state of Florida.     

The development of mathematical competence in Flemish preservice elementary school teachers

A large-scale longitudinal study was conducted in which the elementary mathematical knowledge and skills of a large group of Flemish preservice elementary school teachers from 15 different institutes was assessed by means of a paper-and-pencil test that was administered both at the beginning and at the end of their 3-year training. The 30-items test covered the new standards for mathematics in the elementary school curriculum in Flanders. The test was divided in six subsets differing in terms of the curricular subdomain and of the cognitive operations being addressed by the item. The results confirmed the frequently heard concern that at the beginning of their training preservice elementary school teachers have rather weak mathematical competencies. At the end of their 3-year training, the overall test performance had become substantially better, although there were still reasons to be seriously concerned about the readiness of some student teachers to teach mathematics to elementary school children. A number of more specific comparisons helped to identify the relative role of two different factors—selection and instruction—in student teachers’ gain from pretest to posttest. Besides documenting the development of elementary mathematical competence in preservice elementary school teachers, the study also resulted in an instrument for (self-) assessment of elementary school mathematical competence. This instrument is now being used in many institutes for elementary school teacher training in Flanders.     

Using Evidence‐Based Practices to Build Mathematics Competence Related to Conceptual,Procedural, and Declarative Knowledge

Abstract Mathematics continues to be one of the most difficult components of the school curriculum for students with learning disabilities (LD). The National Council for Teachers of Mathematics, in conjunction with current educational legislation, challenges teachers to maintain high standards for student performance in mathematics. Fortunately, over the past two decades, researchers have identified and validated a number of instructional practices that help students with LD understand and use mathematics in meaningful ways. The purpose of this article is to discuss instructional guidelines and evidence‐based practices for building conceptual, procedural, and declarative knowledge within a comprehensive mathematics curriculum. The importance of balancing these three knowledge areas across mathematics content areas is noted.     

Do parental attitudes toward and expectations for their children's education and future jobs matter for their children's school achievement?

The traditional discourse in the scholarship on cultural capital theory has focused on how exclusive participation in elite status culture by students from higher socioeconomic status families benefits their learning in schools, the effects of which are most evident in linguistic subject areas such as reading achievement. However, some scholars have argued that cultural capital is not restricted to elite status culture but could include parental familiarity with school evaluation standards and job market requirements, and that the effects could transcend languages to include performance domains with more objective evaluation that are susceptible to school influences (e.g. mathematics and science). The present study systematically examines this position using data involving 96,591 15‐year‐old students from 3602 schools in eight countries who participated in the Programme for International Student Assessment 2012. Results of three‐level hierarchical linear modelling showed positive relationships between seven cultural capital variables and student mathematics achievement. The cultural variables comprised: home educational resources; parental educational attainment and occupational status; parental expectations of their children's educational attainment, future career in mathematics and school; and parental valuing of mathematics. In particular, the three parental expectations variables had substantively larger effect sizes on student achievement than the other cultural capital variables. The results demonstrated that parental familiarity with school evaluation standards and future job requirements, especially as measured by parental expectations, may constitute cultural capital that privileges student mathematics achievement in schools.     

The Link Between Middle School Mathematics Course Placement and Achievement

The proportion of eighth graders in United States public schools enrolled in algebra or a more advanced mathematics course doubled between 1990 and 2011. This article uses Early Childhood Longitudinal Study's Kindergarten Cohort data to consider the selection process into advanced middle school mathematics courses and estimate the effects of advanced courses on students’ mathematics achievement (n = 6,425; mean age at eighth grade = 13.7). Eighth‐grade algebra and geometry course placements are academically selective, but considerable between‐school variation exists in students’ odds of taking these advanced courses. While analyses indicate that advanced middle school mathematics courses boost student achievement, these effects are most pronounced in content areas closely related to class content and may be contingent on student academic readiness.     

Teacher behavior under performance pay incentives

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.     

School Autonomy: A Comparison between China and the United States

Abstract

This study examined and compared school autonomy in China and the United States. Based on the international PISA 2012 school data, the authors examined three aspects of school autonomy. We found that in comparison with the United States, (1) principals from China were less likely to have responsibility over eleven school decisions (hiring teachers, firing teachers, salary increase, budget formulation, budget allocation, disciplinary policies, assessment policies, student admittance, textbook selection, course content, and courses offered) and were similar in having responsibility over teacher start salaries, and (2) teachers from China were less likely to have responsibility over six school decisions (hiring teachers, budget formulation, disciplinary policies, textbook selection, course content, and courses offered), were more likely to have responsibility over two decisions (firing teachers, student admittance), and were similar in having responsibility over four decisions (teacher start salaries, salary increase, budget allocation, and assessment policies). We also found that schools in China had (1) lower responsibility for curriculum/assessment and lower responsibility for resource allocation and (2) a lower level of teacher participation/autonomy. The findings have implications for educational policy in China and the United States.     

Profiles of Chilean students according to academic performance in mathematics: An exploratory study using classification trees and random forests

Attempting to deepen the understanding of factors that explain student performance, this study seeks to identify and characterize profiles of Chilean students based on academic performance in mathematics. As analytical method, statistical techniques known as random forest (RF) and classification and regression tree (CART) were used to identify groups of eighth-grade elementary students according to their performance in 2011 test, using features related to individual and family behavior. The analysis was performed with a database provided by the Education Quality Measurement System of Chile. Results show that “parents’ educational expectations” (42.7%) is key factor to obtain the best children's performances. Additionally, the analysis showed that the “type of school” (26.6%) and the “index of mathematical abilities” (26.1%) influence good performance.     

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.     

Educational Aims,Ideals, and Activities

Abstract

The effects on student performance and student attitudes of varying the instructional locus of control between students and teachers were investigated. A 2 X 2 factorial design was used that included either teacher regulation or student regulation of 1) the setting of weekly learning goals, and 2) the evaluation of weekly work. After a 4-week period, a mathematics achievement test and a student attitude survey were administered. Results indicated that although teachers set more individual learning goals for students, students who set their own learning goals attained more of them. Students tended to evaluate their work more favorably than teachers, and work evaluations from both teachers and students were higher for students who initially set their own learning goals. In addition, students who were given the opportunity to set their own learning goals reported better goal-setting ability than those for whom goals were externally imposed by the teacher. As predicted, the self-regulated goal setting and evaluation were found to be significantly related to attitudes, but not to mathematics achievement.     

Effects of a reform high school mathematics curriculum on student achievement: whom does it benefit?

This study compared the effects of an integrated reform-based curriculum to a subject-specific curriculum on student learning of 19,526 high school algebra students. Using hierarchical linear modelling to account for variation in student achievement, the impact of the reform-based Core-Plus Mathematics curricular materials on student test scores is compared to the subject-specific curriculum. Findings from this study indicate that students enrolled in integrated mathematics outperformed subject-specific students on an Algebra I exam (highly aligned with content), and performed equally on an Algebra II exam (poorly aligned). High minority students in high-need schools demonstrated higher performance when they were enrolled in integrated mathematics.     

School effects on Chilean children’s achievement growth in language and mathematics: An accelerated growth curve model

This study investigates school effects on primary school students’ language and mathematics achievement trajectories in Chile, a context of particular interest given its large between-school variability in educational outcomes. The sample features an accelerated longitudinal design (3 time points, 4 cohorts) together spanning Grades 3 to 8 (n = 19,704 students in 156 schools). The magnitudes of school effects on students’ growth trajectories were found to be sizeable (generally larger than school effects in Western industrialised countries) and moderately consistent across school subjects. School composition effects on student achievement status were found for both school subjects. However, there was no evidence of composition effects on student achievement growth. The study provides new evidence on the size and nature of school effects in a developing country context based on state-of-the-art methods (i.e., accelerated longitudinal and growth curve models).     

SCIENCE AND MATHEMATICS ACHIEVEMENT IN AUSTRALIA: THE ROLE OF SCHOOL SOCIOECONOMIC COMPOSITION IN EDUCATIONAL EQUITY AND EFFECTIVENESS

In this study, we systematically unpack relationships among student socioeconomic status (SES), science and mathematics achievement, and student interest in science in the context of varying school socioeconomic composition. Using the most recent Programme for International Student Assessment dataset for Australia, we found that increases in school SES are consistently associated with substantial increases in science and mathematics performance. This pattern of association held for all groups regardless of their individual SES. However, our findings also show that students’ interest in science was not associated with varying school SES, and only marginally and inconsistently associated with individual SES. We discuss policy implications and strategies for mitigating the influence of school socioeconomic composition on science and mathematics performance, and for the achievement of more equitable and effective educational outcomes generally.
