In this investigation, we analyzed US middle school students’ (grades 6–8) gestures and speech during interviews to understand students’ reasoning while interpreting quantitative patterns represented by Cartesian graphs. We studied students’ representational fluency, defined as their abilities to work within and translate among representations. While students translated across representations to address task demands, they also translated to a different representation when reaching an impasse… 
Relationships Between Semiotic Representational Transformations and Performance Outcomes in Digital Math Games
The purpose of this study was to examine relationships between students’ semiotic representational transformations and students’ mathematics performance outcomes in digital math games. The study
Translating between representations in a social context: a study of undergraduate science students’ representational fluency
Interacting with and translating across multiple representations is an essential characteristic of expertise and representational fluency. In this study, we explored the effect of interacting with
The Future of Embodied Design for Mathematics Teaching and Learning
A rising epistemological paradigm in the cognitive sciences—embodied cognition—has been stimulating innovative approaches, among educational researchers, to the design and analysis of STEM teaching
How Students Connect Descriptions of Real-World Situations to Mathematical Models in Different Representational Modes
TLDR
This work focuses on two elements that can hinder the translation of a problem situation into a mathematical model by relating it to the phenomenon of students’ overreliance on the linear model and their (lack of) representational fluency.
Understanding Graphs: Modeling Processes, Prerequisites and Influencing Factors of Graphicacy
TLDR
It is suggested that students are facing different challenges when solving graph reading tasks, and a high level of mastery of these basic numerical abilities was repeatedly observed to be associated with actual numerical competencies but also predictive of future numerical competences as well as mathematical achievement in school.
Cognitive Task Analysis for Implicit Knowledge About Visual Representations With Similarity Learning Methods
TLDR
Together, the experiments provide the first method to assess students' perceptual competencies implicitly, without requiring verbalization or assuming explicit visual attention, and these findings have implications for the design of instructional interventions that help students acquire perceptual representational competencies.
Mathematical Thinking Process of Autistic Students in Terms of Representational Gesture
The aim of this study is to describe the mathematical thinking process of autistic students in terms of gesture, using a qualitative approach. Data collecting is conducted by using 3 (three)

Gestures at Work in Sense-Making Science Talk
Emerging research suggests that problem solvers employ distinctive gestures as they strive to explain scientific phenomena. Because the learning sciences increasingly assign explanation a central
Gesture-Speech Mismatch and Mechanisms of Learning: What the Hands Reveal about a Child′s State of Mind
TLDR
The majority of children who learned to correctly solve equivalence problems did so by adhering to the hypothesized path: They first produced a single, incorrect procedure, then entered a discordant state in which they produced different procedures--one in speech and another in gesture.
“No! He starts walking backwards!”: interpreting motion graphs and the question of space, place and distance
This article deals with the interpretation of motion Cartesian graphs by Grade 8 students. Drawing on a sociocultural theoretical framework, it pays attention to the discursive and semiotic process
Hand and Mind: What Gestures Reveal about Thought
What is the relation between gestures and speech? In terms of symbolic forms, of course, the spontaneous and unwitting gestures we make while talking differ sharply from spoken language itself.
Pattern Generalization with Graphs and Words: A Cross-Sectional and Longitudinal Analysis of Middle School Students' Representational Fluency
Cross-sectional and longitudinal data from students as they advance through the middle school years (grades 6–8) reveal insights into the development of students' pattern generalization abilities. As
An embodied cognition perspective on symbols, gesture, and grounding instruction
The need to understand and predict behaviour in complex settings such as the classroom and the workplace elevates the importance of the role of context and communication in building models of
Indexical understanding of instructions
TLDR
Support for the indexical hypothesis is demonstrated by manipulating the opportunity to index words to objects while acquiring background information about how to use a compass and map to identify landmarks.
Spatial schemas and abstract thought
TLDR
This book proposes the means by which spatial structures might be adapted for nonspatial purposes, and it considers alternatives to spatial coding as a basis for abstract thought.
