In spring 2010, Houghton Mifflin Harcourt (HMH) began planning a pilot of an application for the Apple iPad, "HMH Fuse: Algebra 1," which was then in development. The application was to be piloted in four California school districts during the 2010-2011 school year. HMH contracted with Empirical Education Inc. to conduct a one-year randomized experiment aimed at producing evidence of the effectiveness of "HMH Fuse" for increasing algebra achievement and student attitudes toward math for seventh and eighth grade students. After a one-year pilot implementation with "HMH Fuse," the authors do not have evidence of a generalizable effect of the program on algebra achievement. They did not find clear evidence that the effect was dependent on local conditions. For two teachers in one school--selected for the study on the basis of experience with technology innovations--there was an impact. While they cannot generalize the results beyond these two teachers, the study is suggestive of approaches that may lead to success with applications such as "HMH Fuse."
