Teaching Practices and Student Achievement Report of First-Year Findings from the 'Mosaic' Study of Systemic Initiatives in Mathematics and Science

In our increasingly technological society, improving students' performance in mathematics and science has become a critical challenge. During the 1990s, the National Science Foundation funded a series of Systemic Initiatives designed to change the way these subjects are being taught in schools throughout the country. These initiatives sought to align all aspects of the educational system in support of ambitious curriculum and performance standards, with particular emphasis on teacher training and professional development to promote effective changes in instructional practice.
