This study investigates the influence of teacher understanding on student understanding through teacher practice. Three elementary school teachers participated in a university course that discussed mathematical and pedagogical knowledge regarding addition and subtraction word problems. The data from this study were analyzed qualitatively to…

Direct linkGibson, David – Mathematics Teaching, 2011
In the September 2010 issue of "Mathematics Teaching," Tom O'Brien offered practical advice about how to teach addition, subtraction, multiplication, and division and contrasted his point of view with that of H.H. Wu. In this article, the author revisits Tom's examples, drawing on his methodology while, hopefully, simplifying it and giving it…

Lopez Fernandez, Jorge M.; Velazquez Estrella, Aileen – Teaching Children Mathematics, 2011
In this article, the authors discuss their approach to column addition and subtraction algorithms. Adapting an original idea of Paul Cobb and Erna Yackel's from "A Contextual Investigation of Three-Digit Addition and Subtraction" related to packing and unpacking candy in a candy factory, the authors provided an analogous context by…

Namkung, Jessica M.; Fuchs, Lynn S. – Learning Disabilities Research & Practice, 2012
The purpose of the study was to examine differences in early numerical competencies, as well as subtraction skill, as a function of children's mathematics difficulty (MD) status: computational difficulty (CD), word problem-solving difficulty (PD), concurrent difficulty (CDPD), or neither difficulty (i.e., typically developing; TYP). Based on…

Mancl, Dustin B.; Miller, Susan P.; Kennedy, Meghan – Learning Disabilities Research & Practice, 2012
Mathematics continues to be one of the most challenging aspects of the school curriculum for students with learning disabilities. The provision of pedagogically sound foundational computation and word problem instruction in the elementary grades is critical for students to progress through the mathematics curriculum successfully. A…

Thevenot, Catherine; Castel, Caroline; Fanget, Muriel; Fayol, Michel – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2010
The authors used the operand-recognition paradigm (C. Thevenot, M. Fanget, & M. Fayol, 2007) in order to study the strategies used by adults to solve subtraction problems. This paradigm capitalizes on the fact that algorithmic procedures degrade the memory traces of the operands. Therefore, greater difficulty in recognizing them is expected…

De Smedt, Bert; Torbeyns, Joke; Stassens, Nick; Ghesquiere, Pol; Verschaffel, Lieven – Learning and Instruction, 2010
This study examined the development of indirect addition as an alternative for solving multidigit subtractions, by means of two learning environments in traditionally schooled third-graders in Flanders (Belgium). Thirty-five third-graders, who did not demonstrate mastery of indirect addition, participated in an Explicit (n = 20) or Implicit (n =…

Edwards-Omolewa, Nicola D. – Investigations in Mathematics Learning, 2011
Gender differences in the strategies elementary school children use to solve multidigit addition and subtraction story problems that require regrouping are investigated in two studies. Study 1 replicates the Fennema and colleagues (1998) study by reexamining previously published data on 72 children's addition and subtraction solution strategies.…

Carr, Martha; Taasoobshirazi, Gita; Stroud, Rena; Royer, James M. – Contemporary Educational Psychology, 2011
One hundred and seventy-eight second grade students from two states (Georgia and Massachusetts) participated in an experiment in which they were randomly assigned to either (1) a computer program designed to increase fluency in addition and subtraction, (2) a program designed to improve cognitive strategy use for addition and subtraction, (3) a…

Choppin, Jeffrey – Mathematics Education Research Journal, 2011
This study explores the extent to which a teacher elicited students' mathematical reasoning through the use of challenging tasks and the role her knowledge played in doing so. I characterised the teacher's knowledge in terms of a "local theory" of instruction, a form of pedagogical content knowledge that involves an empirically tested set of…

Boets, Bart; De Smedt, Bert; Ghesquiere, Pol – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
Recent findings suggest deficits in coherent motion sensitivity, an index of visual dorsal stream functioning, in children with poor mathematical skills or dyscalculia, a specific learning disability in mathematics. We extended these data using a longitudinal design to unravel whether visual dorsal stream functioning is able to "predict"…

Torbeyns, Joke; Ghesquiere, Pol; Verschaffel, Lieven – Learning and Instruction, 2009
This article discusses the characteristics of the indirect addition strategy (IA) in the domain of multi-digit subtraction. In two studies, adults' use of IA on three-digit subtractions with a small, medium, or large difference between the integers was analysed using the choice/no-choice method. Results from both studies indicate that adults…

Murata, Aki; Bofferding, Laura; Pothen, Bindu E.; Taylor, Megan W.; Wischnia, Sarah – Journal for Research in Mathematics Education, 2012
This study investigated how elementary teachers in a mathematics lesson study made sense of student learning, teaching, and content, as related to using representations in teaching multidigit subtraction, and how changes occurred over time in their talk and practice. The lesson-study process paved a group talk path along which teacher talk shifted…

Boswell, M. Alison; Knight, Victoria; Spriggs, Amy D. – Rural Special Education Quarterly, 2013
This investigation used an ABAB withdrawal design to determine the effect of self-monitoring using the MotivAider® (MotivAider, 2000) on percentage of intervals of on-task behavior by an 11-year old male with a moderate intellectual disability who attended a rural middle school. The MotivAider® is a small device, the size of a pager, which can be…

Karp, Karen; Caldwell, Janet; Zbiek, Rose Mary; Bay-Williams, Jennifer – National Council of Teachers of Mathematics, 2011
What is the relationship between addition and subtraction? How do individuals know whether an algorithm will always work? Can they explain why order matters in subtraction but not in addition, or why it is false to assert that the sum of any two whole numbers is greater than either number? It is organized around two big ideas and supported by…
