This report examines the accomplishments of a collaborative project to enhance student learning and motivation in mathematics in a middle school serving a changing population of students, the majority of whom are Latino. The partnership joined together the mathematics teachers and site administrator of the school, university mathematicians and educational researchers, and the management and workers from a research-and-development-oriented electronics firm. The partners in the project believed that a thematic approach to mathematics instruction might address a number of the hypothesized causes of low achievement. Results suggest that the project school is doing an especially effective job at the seventh grade level. All students showed improvement against the national norms regardless of mathematics curriculum. Eighth grade data were less encouraging but the students who were taught using a thematic curriculum held their own against the national norms. Students in the thematic class scored better on the Mathematics in Manufacturing criterion test that sampled material covered in a manufacturing unit. Contains 33 references. (PVD)
