大学专业课程成绩结构与质量分析--以生态学专业为例

课程成绩是考试成绩与平时成绩的综合,是衡量教学过程中教与学质量的重要手段。以2002级生态学专业四年课程成绩为实例,分析大学学生课程成绩的结构与质量,表明基础课和专业选修课成绩偏低、难度系数较大、区分度较好,专业课课程成绩偏高、难度系数较小、成绩较集中、不能反映学生的真实水平,专业基础课和专业选修课课程成绩结构与质量介于基础课和专业课之间。针对不同类型课程成绩结构与质量,建议加强课程教学过程与考试质量监控和成绩评定标准与保证体系建设。

Whose children gain from starting school later? – evidence from Hungary

We look at the effect of school starting age on standardized test scores using data covering all Grade 4 and Grade 8 students in Hungary. Instrumental variables estimates of the local average treatment effect suggest that children generally gain from starting school 1 year later, and the effects are much stronger in the case of students coming from low-educated families. We test the robustness of the results by allowing for heterogeneity in the age effect, distinguishing between fields of testing, using discontinuity samples and relying on alternative data. The hypothesis that delayed entry has a stronger impact on low-status children is supported by the robustness checks. The observed patterns are most probably explained by the better performance of kindergartens, as opposed to schools, in developing the skills of low-status children.     

Schools, school quality and achievement growth: Evidence from the Philippines

A broad literature seeks to assess the importance of schools, proxies for school quality, and family background on children's achievement growth using the education production function. Using rich data from the Philippines, we introduce and estimate a model that imposes little structure on the relationship between intake achievement and follow-up achievement and evaluate school performance based on this estimated relationship. Our methods nest typical value-added specifications that use test score gains as the outcome variable and models assuming linearity in the relationship between intake and follow-up scores. We find evidence against the use of value-added models for our data and show that such models give very different assessments of school performance in the Philippines. Using a variety of tests we find that schools matter in the production of student achievement, though variation in performance across schools only explains about 4.4–5.3% of the total (conditional) variation in follow-up achievement. Schools providing basic facilities—in particular schools providing electricity—are found to perform much better in the production of achievement growth.

DOES FAMILY BACKGROUND MATTER FOR LEARNING IN EAST AFRICA?

ABSTRACT

The extent to which differences in family background characteristics explain differences in learning outcomes between children captures the extent of equality in educational opportunities. This study uses large-scale data on literacy and numeracy outcomes for children of school age across East Africa (Kenya, Tanzania and Uganda) to investigate the contribution of family background to learning differences. We find that learning differences between children from less-advantaged households and those from more-advantaged households equals around one year or more of effective learning on average. Even so, family background does not fully explain why children of school starting age display large differences in learning between countries.     

Low test scores in Latin America: poor schools,poor families or something else?

Latin American students consistently score low on international tests of cognitive skills. In the PISA 2012 results, students in seven Latin American countries had an average score of 395 in mathematics, or about 100 points lower than the average score of 497 in four Scandinavian countries. We estimate the effect of socioeconomic characteristics on student scores in Latin America and Scandinavia and find that 50 points of the difference are explained by Latin American parents’ lower average educational and socioeconomic characteristics, 25 points are explained by Latin America’s weak cultural orientation toward reading books and the remaining 25 points are explained by the lower effectiveness of Latin American educational systems in teaching cognitive skills.
