The Learning Equation (TLE) is a software product that provides mathematics programming to students. It was introduced to grade 9 students in Alberta in 1997-1998, and in 1998-1999, its use was extended to grades 7, 8, and 10. TLE is designed to follow the Alberta mathematics curriculum closely. It can be implemented in several ways, and in some schools is the main delivery method, entirely replacing textbooks. In other schools, it is a supplement or a remedial resource. This study examined the effects of TLE on student achievement and attitudes and on teachers' effective delivery of mathematics. Interviews were conducted with 1,186 students, and data, including achievement findings, were available from several sources. Overall, by grade 9, students who used TLE slightly outperformed those who did not. TLE did not appear to make students feel more positive about mathematics, but in some cases, it reduced negative feelings. Teachers reported positive attitudes about TLE, but wished for closer communication with the TLE development community. In general, study findings reflect positively on TLE and indicate that it is a viable alternative to teaching mathematics using a textbook. Three appendixes describe study methodology and present pretest and posttest student responses. (Contains 17 tables and 23 graphs.) (SLD)
