Impact Of The Order Of Eac And Sos During Instruction On Ratios, Josephine Marlene Derrick
Impact Of The Order Of Eac And Sos During Instruction On Ratios, Josephine Marlene Derrick
Boise State University Theses and Dissertations
The purpose of this study was twofold. First, a set of instructional materials surrounding proportional reasoning with ratios (particularly the understanding of the multiplicative relationship between the quantities within the ratio, referred to as functional reasoning throughout this thesis) were created using the free online tool, Desmos, with a goal of determining the impact of the lesson materials on student understanding. The second goal was to explore the impact of the order in which two instructional strategies, Explicit Attention to Concepts (EAC) and Students’ Opportunity to Struggle (SOS), had on student understanding. The lesson materials consisted of 5 lessons. These …
Discursive Negotiation And (Re)Construction Of Professional Identities For Mathematics, Angela Rae Crawford
Discursive Negotiation And (Re)Construction Of Professional Identities For Mathematics, Angela Rae Crawford
Boise State University Theses and Dissertations
This qualitative study explores how discourse communicates professional identities for mathematics in a context of pedagogical reform. The central research question is: In a case of mandatory mathematics professional development, what professional identities for mathematics are expressed, (re)constructed, and negotiated through discourse? This study takes a poststructuralist approach to discourse analysis. The purpose is to describe ways discourse communicates professional identities, or understandings about what it means to be a good mathematics teacher, in a context that may ask teachers to change their pedagogical practice. Data were collected by recording a mandatory, full-day professional development meeting for mathematics teachers of …
Conceptual Understanding Of Fractions And Decimals For Fourth Grade Students, Sarah J. Appleton
Conceptual Understanding Of Fractions And Decimals For Fourth Grade Students, Sarah J. Appleton
Boise State University Theses and Dissertations
A study was conducted in two 4th grade classrooms based on current research of foundational concepts of fraction and decimal knowledge, socio-cultural learning theory, cognition and international mathematics education. The goal of this study was for students to acquire conceptual and procedural knowledge of fraction and decimal concepts. When students have multiple experiences delving into rigorous tasks with fractions and decimals, researchers (Lamon, 2006; Siegler & Alibali 2005) suggest students will show an increase in understanding. Cognition and developmental stages were examined and incorporated within the suggested tasks of the instructional unit. With assistance from current research, this study demonstrated …
