Promoting Decimal Number Sense and Representational Fluency

چکیده
tThe abstract nature of mathematics requires the communication of mathematical ideas through multiple representations, such as words, symbols, pictures, objects, or actions. Building representational fluency involves using mathematical representations flexibly and being able to interpret and translate among these different models and mathematical concepts. This article shares a collaborative lesson study experience in planning and teaching a unit on decimals. Participants included fifthand sixth-grade teachers and lesson study facilitators, including a university mathematics educator, a doctoral student, and a school mathematics specialist. The lesson was taught in a fifth-grade class with a high population of English language learners (ELL) and special needs students. The overarching goal of the lesson study was to develop students’ representational fluency Promoting Decimal Number Sense and Representational Fluency

A systematic investigation of the link between rational number processing and algebra ability.
Recent research suggests that fraction understanding is predictive of algebra ability; however, the relative contributions of various aspects of rational number knowledge are unclear. Furthermore, whether this relationship is notation-dependent or rather relies upon a general understanding of rational numbers (independent of notation) is an open question. In this study, college students complet...
متن کاملInferential Pitfalls in Decoding Neural Representations
A key challenge for cognitive neuroscience is to decipher the representational schemes of the brain. A recent class of decoding algorithms for fMRI data, stimulus-feature-based encoding models, is becoming increasingly popular for inferring the dimensions of neural representational spaces from stimulusfeature spaces. We argue that such inferences are not always valid, because decoding can occur...
متن کاملDoes Representational Understanding Enhance Fluency - Or Vice Versa? Searching for Mediation Models
Conceptual understanding of representations and fluency in using representations are important aspects of expertise. However, little is known about how these competencies interact: does representational understanding facilitate learning of fluency (understandingfirst hypothesis), or does fluency enhance learning of representational understanding (fluency-first hypothesis)? We analyze log data o...

متن کاملVerbal fluency performance in normal adult population in Iran: Norms and Effects of age, education and gender
Objective: Verbal fluency is a cognitive function that can be easily assessed in bedside and provide useful data for clinical assessment of a variety of cognitive functions. We decided to provide a standardized test for the assessment of verbal fluency in Persian language, including both phonemic and semantic fluency subtests. Method: First, three letters (P, D, and Sh) and three categories (...
