This is one of a series of reports on the National Longitudinal Study of Mathematical Abilities (NLSMA). It is an analysis of a follow-up survey conducted on the Z-Population (students in grades 10-12) approximately one year after the students completed grade 12. (NLSMA Reports Nos. 3, 6, 7, and 9 contain background information on the Z-Population, on the scales and tests used, and on the data gathered.) General information about the survey and the responses received are given. Students were then grouped according to type of mathematics textbooks used (modern or conventional) and an extended series of Chi-square analyses performed. The data resulting from these analyses are given and a discussion presented that does not attempt to explain all of the observed trends. Instruments used to collect information are included in the report. For related documents, see ED 044 277 through ED 044 283, ED 044 310, ED 045 447, and SE 016 669 through SE 016 691. (LS)
