Classroom sex composition and first-grade school outcomes: The role of classroom behavior

Using nationally representative data from the Early Childhood Longitudinal Study-Kindergarten Cohort (N = 21,409; 10,452 girls and 10,957 boys; mean age = 7.24 years), the association between first-grade classroom sex composition (CSC), measured as the percentage of female students, and end of the year academic (reading, mathematics) and socio-emotional (externalizing problems, internalizing problems, self-control, interpersonal skills) outcomes was examined. Using multilevel modeling techniques and controlling for prior achievement levels, CSC was positively associated with children’s reading achievement at the end of first grade; students performed better in reading in classes with a higher percentage of female students. CSC was also associated with three of the socio-emotional outcomes; controlling for prior levels, students in classrooms with a higher percentage of girls had better self-control and interpersonal skills and fewer internalizing problems. Classroom behavior mediated the effects of CSC on reading achievement and the socio-emotional outcomes. Implications for the composition of first-grade classrooms are discussed.     

"兴边富民行动"的意义

Why do Asian Americans academically outperform Whites? – The cultural explanation revisited

We advocate an interactive approach to examining the role of culture and SES in explaining Asian Americans' achievement. We use Education Longitudinal Study (ELS) 2002 baseline data to test our proposition that the cultural orientation of Asian American families is different from that of white American families in ways that mediate the effects of family SES on children's academic achievement. The results support our hypothesis, indicating that: (1) SES's positive effects on achievement are stronger among white students than among Asian-Americans; (2) the association between a family's SES and behaviors and attitudes is weaker among Asian-Americans than among Whites; (3) a fraction of the Asian-White achievement gap can be accounted for by ethnic differences in behaviors and attitudes, particularly ethnic differences in family SES's effects on behaviors and attitudes. We find that Asian Americans’ behaviors and attitudes are less influenced by family SES than those of Whites are and that this difference helps generate Asians’ premium in achievement. This is especially evident at lower levels of family SES.     

The academic attitudes of American teenagers, 1990–2002: Cohort and gender effects on math achievement

Using data from the National Education Longitudinal Study of 1988 and the Education Longitudinal Study of 2002, I compare the academic attitudes of high school students from Generation X and the Millennial Generation. I then analyze the effects these attitudes have on mathematics achievement test scores. Compared to the earlier group, students in the later cohort were less likely to indicate academic reasons for attending school and largely perceived their friends as being less engaged academically. Students in both cohorts whose friends held academic values experienced an increase in math scores. The more students in the earlier cohort disagreed that they came to school for academic reasons, the more their math scores decreased; this relationship did not appear for the later cohort. Females in each cohort showed stronger academic attitudes than males; additionally, believing that popularity was important was associated with lower test scores for females, but not males, in the Millennial cohort.     

区域性学业水平测试质量分析——小学数学学业水平检测试卷与课程标准一致性的视角

区域性学业水平测试是地方教育行政部门监测教育质量的重要方法。因此,分析区域性学业水平测试质量就显得十分重要。为此,借鉴韦伯一致性分析模式,对某地区小学数学学业水平检测试卷的质量进行了尝试探究,即从学习领域和年级两个方面分析了区域性小学数学学业水平测试与课程标准的一致性水平状况及特征。同时,还从数与代数、空间与图形、统计与概率、实践与综合应用等学习领域和知识种类、知识深度、知识广度和知识分布平衡性等"一致性维度"进行了归因分析。     

The Social Ecology of Race and Ethnicity School Achievement Gaps: Economic,Neighborhood, School,and Family Factors

This study used a nationally representative sample of middle and high school students to examine the degree to which economic, neighborhood, school, and family factors contributed to three points on a proposed school outcome continuum: (1)avoidance of problem behavior, (2)sense of school coherence, and (3)grades. Multilevel models were employed to account for the clustering of students inside schools. Results suggested that though family and neighborhood social factors contribute to variance in school outcomes, family and neighborhood economic factors revealed the largest potential to explain and therefore present leverage points to reduce race and ethnicity achievement gaps.     

庆阳市38所乡镇初级中学英语成绩测试调研报告

经过对庆阳市38所乡镇初级中学英语成绩测试现状的调研,发现这些学校的测试实践科学性不足,测试体系不完善,测试结果不能有效地指导教学。要落实新课程标准的各项目标,搞好教改,就必须规范和加强语言测试工作。     

论口头流传中的悦城龙母传说

口头流传的悦城龙母传说,除了在核心情节与史籍记载的龙母传说保持一致外,已发生很大变异。断尾龙祭母的故事类型与其它故事情节不同程度地糅合在一起,从而使悦城龙母传说更富有世俗生活气息,龙母与五龙子的形象塑造得更为生动感人,而且深切传达了民众的理想、愿望和欲求,是传统农业社会民众生活世界、思想观念的一个侧面反映。     

试论大学课堂教育目标的实现

对于课堂教学而言,既要重视对学生知识的传授,也要重视对学生能力和素质的培养,做到"教"和"育"的完美结合。大学课堂教育目标的实现,主要依靠以下四种途径:选择和组织教学内容以建构学生的知识体系;利用讲课艺术和挖掘课程的兴奋点以激发学生学习兴趣;依靠创新教育培养学生的创新能力;发掘各类课程的思想政治教育资源以塑造学生的价值观念。
