Primary school enrollments have increased rapidly in sub‐Saharan Africa, spurring concerns about low levels of learning. We analyze field experiments in Kenya and Uganda that assessed whether the Reading to Learn intervention, implemented by the Aga Khan Foundation in both countries, improved early‐grade literacy as measured by common assessments. We find that Ugandan literacy (in Lango) increased by 0.2 standard deviations. We find a smaller effect (0.08) on a Swahili literacy test in Kenya. We find no evidence that differential effects are explained by baseline differences across countries in student test scores, classroom attributes, or implementation fidelity. A plausible explanation that cannot be directly tested is differential effective exposure to the literacy treatment in the tested languages. Students in Kenya were tested in Swahili, which is not necessarily the main language of instruction in primary schools, despite official policy. 相似文献

Legislative scholars often assume that legislators are motivated by concerns over re-election. This assumption implies that legislators are forward-looking and are motivated by a concern over what their re-election constituency will look like during their next electoral cycle. In this research, we show how the forward-looking nature of legislators motivates members of the U.S. House of Representatives to represent both their home district and their neighboring districts in their choices regarding when to support their own party. Using survey responses to the 2006, 2008, and 2010 Cooperative Congressional Elections Study to construct measures of Congressional District ideology, empirical analysis is strongly supportive of our claims. Legislators’ choices are strongly influenced both by the ideology of their home district and that of the districts that neighbor their home district. Thus, the electoral connection between citizens and representatives extends beyond a legislator’s own constituents to include the constituents in neighboring districts. 相似文献
