Concepts Of Variable In Middle-Grades Mathematics Textbooks During Four Eras Of Mathematics Education In The United States, James K. Dogbey

USF Tampa Graduate Theses and Dissertations

This study used content analysis to investigate the development of the concept of variables in middle grades mathematics textbooks during four eras of mathematics education in the United States (New Math, Back to Basics, Problem Solving, and the NCTM Standards era: 1957 – 2009). It also examined the nature of support that the curricula provide for teachers to enact variables ideas in the classroom. Findings revealed that each of the middle grades mathematics curricula examined used variables, but in varied proportions and levels of complexity. Formal definitions for variables were found in 11 of the …

Ecological, Behavioral, And Curricular Interventions To Prevent Student Problem Behavior: An Approach To Implementing Effective Practices, Lindsey M. Merritt

USF Tampa Graduate Theses and Dissertations

While classroom management has been a highly researched topic in Applied Behavior Analysis, there are few empirically validated methods to effectively disseminate classroom techniques into school settings. There are three main classroom management areas that exist in the literature. These are: a) ecological factors, b) behavior principles, and c) curricular modifications. These three areas have been researched independently and in combination to find best classroom management practices. Although these areas are highly researched, dissemination of these materials into public and private classrooms has fallen far behind. However, researchers are finding specific variables that positively influence the success of programs in …

Proportionality In Middle-School Mathematics Textbooks, Gwendolyn Joy Johnson

USF Tampa Graduate Theses and Dissertations

Some scholars have criticized the treatment of proportionality in middle-school textbooks, but these criticisms seem to be based on informal knowledge of the content of textbooks rather than on a detailed curriculum analysis. Thus, a curriculum analysis related to proportionality was needed.

To investigate the treatment of proportionality in current middle-school textbooks, nine such books were analyzed. Sixth-, seventh-, and eighth-grade textbooks from three series were used: ConnectedMathematics2 (CMP), Glencoe's Math Connects, and the University of Chicago School Mathematics Project (UCSMP). Lessons with a focus on proportionality were selected from four content areas: algebra, data analysis/probability, geometry/measurement, and rational …
