A Randomized Trial on Educational Inputs in Kenya

9511347克雷默有许多关于教育投入对学校表现影响的回溯性统计研究。然而，如果不同教育投入的学校在其他与学校表现相关的未经测量的方面存在系统性差异，这些回溯性研究将是有偏见的。例如，拥有更好设施的学校通常也可能有更有优势或更致力于教育的家长，而这种家长的投入，而不是设施本身，可能要对考试成绩和设施之间的相关性负责。该项目进行了一项随机试验，可以克服过去研究中的许多统计问题。该项目进行了关于教育投入和学校表现的首批随机试验之一。这项试验是基于国际基督教人道主义服务(ITS)的工作，这是一种肯尼亚围棋。它为选定的农村小学提供教科书、练习本、校服、教室建设、课桌和医疗服务。调查人员将随机将一组候选学校分配到对照组或处理组。治疗组中的学校将从ITS获得教育和医疗服务。控制组中的学校将获得医疗服务，以换取参与该计划并配合他们的监测和评估工作。该项目比较了两组学生的课文分数和辍学率的变化。由于援助一揽子计划的不同组成部分将在不同的年份提供，并将影响不同班级的学生，调查员应该能够单独评估不同投入的影响。该项目还审查了额外资源的影响是否因学生性别或社会经济地位或教师培训和教学技术的不同而不同。

9511347 Kremer There have been many retrospective statistical studies of the effect of educational inputs on school performance. However, these retrospective studies will be biased if schools with different educational inputs systematically differ in other, unmeasured ways which are correlated with school performance. For example, schools with better physical facilities may also typically have parents who are more advantaged or more committed to education, and this parental input, rather than the physical facilities themselves, may be responsible for the correlation between test scores and physical facilities. This project conducts a randomized trial which can overcome many of the statistical problems of past studies. The project carries out one of the first randomized trials on educational inputs and school performance. The trial is based on the work of International Christian Humanitarian Services, (ITS), a Kenyan GO. ITS provides selected rural primary schools with textbooks, exercise books, uniforms, classroom construction, desks, and medical services. The investigator will randomly assign a group of candidate schools to either a control group or treatment group. Schools in the treatment group will receive both educational and medical services from ITS. Schools in the control group will receive medical services in return for participating in the program and cooperating with their monitoring and evaluation efforts. The project compares the change in text scores and dropout rates between the two groups. Since different components of the assistance package will be provided in different years, and will affect different classes of students, the investigator should be able to separately assess the impact of the different inputs. The project also examines whether the impact of the additional resources differs with students gender or socio-economic status, or with teachers training and pedagogic techniques.
