An Exploratory Study Of Fifth-Grade Students’ Reasoning About The Relationship Between Fractions And Decimals When Using Number Line-Based Virtual Manipulatives, Scott Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Understanding the relationship between fractions and decimals is an important step in developing an overall understanding of rational numbers. Research has demonstrated the feasibility of technology in the form of virtual manipulatives for facilitating students’ meaningful understanding of rational number concepts. This exploratory dissertation study was conducted for the two closely related purposes: first, to investigate a sample of fifth-grade students’ reasoning regarding the relationship between fractions and decimals for fractions with terminating decimal representations while using virtual manipulative incorporating parallel number lines; second, to investigate the affordances of the virtual manipulatives for supporting the students’ reasoning about the decimal-fraction …

The Impact Of Small Group Intervention Focusing On Operations With Rational Numbers On Students’ Performance In The Florida Algebra I End-Of-Course Examination, Evelyn Dopico

Theses and Dissertations

In Florida, passing the Algebra I end-of-course examination (EOCE) is a graduation requirement. The test measures knowledge of basic algebra. In spring 2015, the Department of Education introduced a different version of the test. For the first two administrations of the new test, the failure rate for 9th-grade students in the state was almost 50%. In contrast, the failure rate for students in the school where this study was implemented exceeded 70%. The purpose of this study was to determine the outcome of small group intervention focusing on operations with rational numbers of high school students’ performance on the Algebra …

The Impact Of Journal Writing On Students’ Understanding Of Rational Number Operations Of Eight Seventh Grade Students At Jackson Middle School, Amanda Marie Smoak

Theses and Dissertations

The purpose of this study was to examine the impact of journal writing on eight seventh grade math students’ understanding of rational numbers in a public school in South Carolina. The literature on mathematical understanding and achievement suggests that students should be taught to write about their mathematical thinking to learn the concepts or reasons behind the procedure to consistently and accurately perform operations with rational numbers (Countryman, 1992; Anderson & Little, 2004; Borasi & Rose, 1989; Ganguli, 1989; Johanning, 2000; Lim & Pugalee, 2004; McCormick, 2010; McIntosh & Draper, 2001; Miller, 1991).

During the course of the study, participants …
