The Department of Education and Skills asked the National Centre for Excellence in Mathematics and Science Teaching and Learning (NCE-MSTL) to review the current mathematics textbooks available for schools for Project Maths, and evaluate them using a version of the TIMSS framework already in use, adapted for the purpose of this study. This study is part funded by the NCCA and is undertaken by the National Centre as part of its brief to advise on matters related to Science and Mathematics teaching and learning. A very tight reporting deadline and resource constraints precluded a more extensive study, however, the study as implemented and reported aspires to best practice standards within its frame.
