Representational disfluency in algebra: evidence from student gestures and speech

  title={Representational disfluency in algebra: evidence from student gestures and speech},
  author={Kristen N. Bieda and Mitchell J. Nathan},
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

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.

Students' Representational Fluency at University: A Cross-Sectional Measure of How Multiple Representations Are Used by Physics Students Using the Representational Fluency Survey.

Analysis of the Representational Fluency Survey over two years with 334 students at The University of Sydney shows that there was a significant difference between the representational fluency of the 1 first year Fundamental and Regular students (low level 1st year physics courses) compared to the1st year Advanced, 2nd year, 3rd year and Postgraduate level students.

Understanding Graphs: Modeling Processes, Prerequisites and Influencing Factors of Graphicacy

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

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.

Making connections among multiple graphical representations of fractions: sense-making competencies enhance perceptual fluency, but not vice versa

The results support the sense-making- first hypothesis, but not the fluency-first hypothesis, and assesses learning processes and learning outcomes related to representational competencies and domain knowledge.



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

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.

Representing Fractions with Standard Notation: A Developmental Analysis.

This study had two purposes: (a) to investigate the developmental relationship between students’ uses of fractions notation and their understandings of part-whole relations; and (b) to produce an

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

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.
