Students participated in teaching and learning sessions focused on developing concepts of fraction and decimal magnitude. The following questions guided this study: (1) How do fifth grade students reason about the magnitude of fractions and decimals? (2) What are the shifts in mathematical thinking that occur with students’ evolving understanding as they progress …

Exploring The Use Of Concrete Materials In Teaching And Learning Of Fractions In Grade Three: A Case Study Of A Public Primary School In Homa-Bay County, Kenya, Ouma Patrick Okoth

Theses & Dissertations

Learners who struggle with mathematics may have difficulties in comprehending the core ideas in mathematics. The concrete-representational-abstract (CRA) instructional sequence of teaching allows teachers to assist pupils in making sense of numbers and the mathematical concepts they represent. The use of concrete materials is critical in the teaching of mathematics to young children; they are the major instruments that early childhood teachers use to train young learners in their mathematics classes today. To encourage the use of concrete materials in mathematics instruction, this research investigates how mathematics teachers use concrete materials in the teaching and learning of mathematics, as well …

The Effect Of Using Virtual Manipulatives On Students’ Ability To Mentally Compare Proper Fractions, William Wilson Mcneary Iii

Dissertations

This study proposes a method to analyze the effects of the use of virtual fraction models (circle/bar/number line) on students’ ability to mentally compare proper fractions. Since developing a sense of magnitude with both whole numbers and rational numbers is highly correlated with improved performance on standardized assessments and improved performance in later algebra classes, special attention is directed to the bar and number line as they are linear representations.

The study used an experimental pretest/posttest group design by randomly assigning subjects within class sections to a control group (physical fraction circles) and treatment groups with seven different methods of …

Examining The Influence Of Number Line Fraction Task Characteristics On Student Work, Sharlee Hatch

Boise State University Theses and Dissertations

Research supports the claim that classrooms with teachers who respond to student thinking in the mathematics classroom will see greater student gains and student success (Lamon, 1996; Sleep & Boerst, 2012). The topic of fractions is both difficult to teach and learn, but has important implications on future success in mathematics and in life. This study set out to explore the ways in which student work is influenced by characteristics of number line fraction tasks. By examining task type, number line structure, and number choice this study shares the way these task characteristics influenced student strategies. The relationship between task …

Investigating Math Students' Ability To Conceptualize Fractions As Two Numerals Having A Single Value, William Carroll Fanning

Open Access Theses & Dissertations

It is no secret that math students of all ages have misconceptions about fractions. Multiple studies have shown that math students invariably see fractions as two separate and unrelated numbers, the numerator and the denominator, rather than a single number with specific value. This study is designed to investigate studentsâ?? interpretations of a fraction in terms of having a single value in relation to its two numbers, the numerator and the denominator.

For the purpose of this study, the investigator developed and pilot-tested seven items that have the potential to uncover whether students attend to the value of a fraction …

Evaluating The Use Of The Math Reasoning Inventory For Improvement In Fraction Instruction, Kathy Huffman Boyer

Dissertations

In an attempt to close the mathematic achievement gap between students from the United States and students from other countries, a new national set of standards, the Common Core State Standards for Mathematics, was developed and adopted by the state of Michigan in 2010. These standards emphasize mathematical reasoning and application, rather than the previous emphasis on performing calculations. Unfortunately, teachers generally have had little training in how to assess students’ mathematical reasoning, how to teach mathematical reasoning, or how to provide remediation to those students who show need. The purpose of this study was to see if use of …

A Learning Progression For Identifying And Placing Fractions On A Number Line, Corinne Dorothy Marshall

Theses Digitization Project

This project provides a learning progression for identifying and placing fractions on a number line that teachers can consider when introducing fractions on number lines. The number line is one of the most useful ways to represent all real numbers in relation to each other. It allows students to experience the density of the number system since all real numbers, natural numbers, whole numbers, integers, rational numbers and irrational numbers have an exact and unique location on the number line.

Influence Of Using Context Supportive Of The Area Model On Sixth Grade Students' Performance When Writing Word Problems For Fraction Subtraction And Multiplication, Monica L. Friske

Electronic Theses and Dissertations

The purpose of this action research study was to evaluate my own practice of teaching writing word problems with fraction subtraction and fraction multiplication using appropriate context. I wanted to see how focusing my instruction on the use of the area model and manipulatives could develop students’ understanding of fractions when writing word problems. I chose this topic because Florida has adopted the Common Core State Standards and will be implementing them in the coming years. These standards encourage the development of deeper understanding of mathematics, including fractions. I hoped this research would give my students the opportunity to make …

The Relationship Between Special Education Teachers' Mathematical Knowledge, Instructional Choices, And Beliefs About Teaching And Learning Mathematics, Virginia Rich Lee

Legacy Theses & Dissertations (2009 - 2024)

Thirty-four certified special education teachers completed four instruments in addition to viewing video recordings of students engaging in mathematical tasks. The mathematical beliefs of special education teachers were investigated through the use of the Mathematics Beliefs Scales (Capraro, 2005). Special education teachers' mathematical knowledge was measured using the Fraction Knowledge Assessment, which included a range of fraction tasks drawn from state and national elementary level mathematics standards. The proposed instruction of the special education teachers was examined through participants' written responses to video recordings of students solving fraction problems. Demographic information was obtained through the use of a questionnaire. Results …

Fostering Teacher's Conceptual Understanding Of Ordering, Adding, And Subtracting Fractions Through School-Based Professional Development, Jessica Maguhn

Electronic Theses and Dissertations

In an attempt to examine my practice of providing conceptually-based professional development on fractions to fifth grade teachers, I conducted a series of four one hour professional development workshops. I focused on the conceptual understanding of ordering, adding, and subtracting fractions. I examined the solution process that teachers used to solve fraction problems and their abilities to explain and justify their solutions in an attempt to interpret their understanding. My data showed the effects of this workshop series. The study helped determine the effects of conceptually-based professional development on fractions as demonstrated in the teachers' discussions, participation, and written explanations.

Electronic Theses and Dissertations

Within a low-performing seventh grade mathematics classroom, communication techniques including discourse, collaborative groups, listening, reading, and writing were implemented during a six week period. This study shows how the use of these techniques led to the twenty four students' conceptual understanding of fraction and decimal concepts. This research study provides insight to the deep-seeded beliefs of low-performing students. It provides a record of how the teacher used communication techniques in the classroom and had a strong positive impact on the attitudes and performance of these struggling students.

Examining Sociomathematical Norms Within The Context Of Decimals And Fractions In A Sixth Grade Classroom, Marino Nardelli

Electronic Theses and Dissertations

Social norms are patterns of behavior expected within a particular society in a given situation. Social norms can be shared belief of what is normal and acceptable shapes and enforces the actions of people in a society. In the educational classroom, they are characteristics that constitute the classroom participation structure. Sociomathematical norms are fine-grained aspects of general social norms specifically related to mathematical practices. These can include, but are not limited to, a student-centered classroom that includes the expectation that the students should present their solution methods by describing actions on mathematical objects rather than simply accounting for calculational manipulations. …

Fraction Multiplication And Division Image Change In Pre-Service Elementary Teachers, Jennifer J. Cluff

Theses and Dissertations

This study investigated three pre-service elementary teachers' understanding of fractions and fraction multiplication and division. The motivation for this study was lack of conceptual understanding of fractions and fraction multiplication and division. Pre-service elementary teachers were chosen because teachers are the conduit of information for their students. The subjects were followed through the fractions unit in a mathematics methods course for pre-service elementary teachers at Brigham Young University. Each subject volunteered to participate and were interviewed and videotaped throughout the study, and they also provided copies of all work done in the fractions unit in the course. The data is …
