This investigation of twentieth century trends in mathematics education includes the survey of existing literature and questionnaires conducted with retired and active Texas teachers. Historical events, trends in curriculum, instruction, learning theories, and contradictions of twenty-year periods are delineated. Questionnaire responses are tabulated along the same periods and vignettes of typical classrooms are drawn from the data. Results of the survey show the impact of societal forces on mathematics curricula, a continued downward expansion of content into lower grades and expanding knowledge of learning processes. A unified mathematics curriculum, classroom-related learning theory research, and further development of team-teaching are postulated as future trends. Recommendations include further examination of trends through isolation of other variables such as region and ethnicity.

The problem of this study was an analysis of the effects of a selected strategy for bringing about changes in stereotypic sex role attitudes of teacher trainees during their teacher education program. The major purposes of this investigation were to (1) develop a preservice treatment program, characterized by the persuasive communication approach, to modify students' stereotypic sex role attitudes, (2) determine the effectiveness of the strategy in modifying students' attitudes, and (3) examine student factors that influence reception and yielding to a persuasive message.
