Given its abstract nature and the highly syntactical competence required by the use of symbolic algebra, research on its teaching and learning must rely on approaches that include semiotic concepts and analyses that recall the history of algebraic ideas, among others. Educational Algebra: A Theoretical and Empirical Approach deals with a theoretical perspective on the study of school algebra, in which both components (semiotics and history) occur. This perspective runs opposite to general theoretical models, since it submits components for the design of local frameworks for theoretical analysis. The Methodological design allows for the interpretation of specific phenomena and the inclusion, within such interpretative frameworks, of evidence not included in more general treatments. Such is the case of phenomena observed in subjects who are initiating the study of symbolic algebra, involving the production of personal sign systems at the intermediate level or the level previous to the mathematical sign system which is to be learned. Disciplines such as Linguistics, Logic, Psycholinguistics, Semiotics, general Cognitive Psychology, Mathematics Psychology, Mathematics Epistemology, History of Mathematics, and others have carried out research on the same topics approached by Mathematics Education and have redefined their results within the framework of their respective fields. Specifically, theorists in Linguistics, Information Processing and Didactics of Mathematics have done important work on the notion of code. Today, this notion is a key element to interpreting the idea of representation in the new explanatory models of cognitive problems placed by alternative teaching approaches, including those involving a technological environment. Additionally, Psycholinguistics and Artificial Intelligence in procedural models of human abilities have intended to explain how and why users of mathematical language naturally and commonly make mistakes in syntactical procedures. Educational Algebra: A Theoretical and Empirical Approach adds to previous developments with priority given to a pragmatic perspective on "meaning in use" over "formal meaning". The bulk of these approaches and others of similar nature have lead to a focus on competence rather than on a user’s activity with mathematical language. Such a shift in perspective has fundamental implications on the way mathematical language is studied. Essentially, Grammar—the abstract formal system—and Pragmatics—the principles of the use of language—are complementary domains in this volume. Both are related to different teaching models, whether new or traditional, used in helping students to become competent users of Algebra. Because of this, Educational Algebra: A Theoretical and Empirical Approach will be of interest to researchers and practitioners within the mathematics education field.

Language and Culture in Mathematical Cognition, Fourth Edition focuses on the role of linguistic and cultural factors in math cognition and development. It covers a wide range of topics, including analogical mapping in numerical development, arithmetic fact retrieval in the bilingual brain, cross-cultural comparisons of mathematics achievement, the shaping of numerical processing by number word construction, the influence of Head Start programs, the mathematical skills of children with specific language impairments, the role of culture and language in creating associations between number and space, and electrophysiological studies of linguistic traces in core knowledge at the neural level. Includes cutting-edge findings, innovative measures, recent methodological advances and groundbreaking theoretical developments -- Synthesizes research from various subdomains of math cognition research -- Covers the full complement of research in mathematical thinking and learning -- Informs researchers, scholars, educators, students and policymakers . --

Che cosa sono le macchine matematiche? Una macchina matematica (in un contesto geometrico) è uno strumento che ha uno scopo fondamentale (indipendentemente dall’uso che poi se ne farà): obbligare un punto, o un segmento, o una figura qualsiasi (sostenuti da un opportuno supporto materiale che li renda visibili) a muoversi nello spazio o a subire trasformazioni seguendo con esattezza una legge astrattamente, matematicamente determinata. Le macchine matematiche sono tra gli strumenti suggeriti per l’attività di laboratorio, nella proposta di nuovi curricoli avanzata dall’Unione Matematica Italiana. Una ampia collezione di macchine (oltre 200), di interesse storico e didattico, è stata ricostruita a Modena, dove è collocato, presso il Dipartimento di Matematica, un laboratorio di ricerca per la didattica della geometria con l’uso di strumenti (il Laboratorio delle Macchine Matematiche). Sono stati ricostruiti curvigrafi, pantografi, prospettografi, modelli tridimensionali di solidi e di curve sezione, strumenti per la soluzione di problemi. Quasi tutti i modelli, realizzati in legno naturale ed effettivamente funzionanti, sono ripresi da fonti storiche dall’antichità classica all’Ottocento. Il Laboratorio è aperto alle scuole su prenotazione e realizza mostre, allestimenti espositivi, laboratori interattivi su richiesta in Italia e all’estero. L’attività del Laboratorio è coordinata dalle due autrici, con la collaborazione dei membri dell'Associazione di promozione sociale Macchine matematiche, di studenti universitari, borsisti, insegnanti. In questo libro sono raccolti i risultati di oltre vent’anni di ricerche didattiche sul tema, realizzate in Italia e all’estero, in tutti gli ordini scolastici. L’esplorazione guidata delle macchine consente di ricostruire il significato geometrico-spaziale di concetti o procedure di solito affrontati solo nel quadro algebrico e di esplorare dinamicamente le configurazioni assunte allo scopo di produrre congetture e costruire dimostrazioni. Le macchine consentono anche di stabilire collegamenti interessanti con l’arte e la tecnologia, rompendo l’isolamento in cui si colloca spesso l’insegnamento della matematica. Al volume è allegato un cd-rom (per Windows) che contiene immagini, animazioni, schede di approfondimento.
