Morgan G. Ames’s The Charisma Machine discusses a philanthropic initiative in this field to build the hand-crank-powered OLPC XO. Stepwise regression has led to doubt about the conclusions of a report in this field written by James S. Coleman. (15[1])Duelling analyses (15[1])of the results (15[1])of a (15[1])Tennessee experiment in this field, Project STAR, (15[1])were written by Alan Krueger and Eric Hanushek, (-5[1])a proponent of value-added models. (-5[1])For research in this field, (15[2])Victor Lavy and Joshua (15[1])(*) Angrist used a regression (-5[1])discontinuity (10[1]-5[1])based on Maimonides’ rule of 40. (10[1]-5[2])Angrist also used lotteries (10[1])to find strong results for the KIPP (10[1])(“kip”) program in this field, (10[2]-5[1])where international research often uses PISA (“PEE-suh”) scores. (10[6])For (10[1])10 points, (10[4])name (10[1])this field where economists have researched the achievement gap (10[1]-5[1])and the (10[1])No Child (10[1])Left (-5[1])Behind (10[2])Act.
