Abstract To plan cluster-randomized trials with sufficient statistical power to detect intervention effects on student achievement, researchers need multilevel design parameters, including measures of between-classroom and between-school differences and the amounts of variance explained by covariates at the student, classroom, and school level. Previous research has mostly been conducted in the United States, focused on two-level designs, and limited to core achievement domains (i.e., mathematics, science, reading). Using representative data of students attending grades 1–12 from three German longitudinal… Continue Reading →

Eric.ed.gov – Baseline Report for the Mixed-Methods Cluster-Randomized Controlled Trial of Impact Network’s eSchool 360 Model in Rural Zambia. Making Research Relevant

eric.ed.gov har udgivet: Low- and middle-income countries have made significant progress getting children into school, but student learning and achievement are often dreadfully low (Berry, Barnett, & Hinton, 2015; Pritchett, 2013). Approximately 250 million children across the world are not acquiring basic reading and math skills, even though about half have spent at least 4 years in school (United Nations Educational, Scientific, and Cultural Organisation, 2014). Zambia faces many common educational challenges. Literacy rates among young Zambian adults ages 15–24 are 58.5% for females and 70.3% for males, despite an average of 7.7 years and 7.9 years of education, respectively (Zambia Demographic and Health Surveys, 2013–14; UNICEF, 2015). Community schools in Zambia are in need of a cost-effective solution for delivering quality education in order to improve learning outcomes. The… Continue Reading →
