We present results from a randomized study of a well-defined use of computers in schools: a popular instructional computer program for pre-algebra and algebra. We assess the program using a test designed to target pre-algebra and algebra skills. Students randomly assigned to computer-aided instruction score 0.17 of a standard deviation higher on pre-algebra/algebra tests than students randomly assigned to traditional instruction. We hypothesize that the effectiveness arises from increased individualized instruction as the effects appear larger for students in larger classes and in classes with high student absentee rates.

In this paper we use a 'market-based' approach to examine whether increased school expenditures are valued by potential residents and whether the current level of public school provision is inefficient. We do so by employing an instrumental variables strategy to estimate the effect of state education aid on residential property values. We find evidence that, on net, additional state aid is valued by potential residents and that school districts do not appear to overspend on education. We also find that school districts may overspend in areas in which residents are poor or less educated, in large districts, and in districts with higher shares of rental property. One interpretation of these results is that increased competition has the potential to reduce overspending on public schools in so...
