As Manipulações em Tela Compondo a Dimensão Corporificada da Cognição Matemática

Abstract

ResumoDispositivos móveis com tela sensível ao toque estão nas mãos de todos. Ou, ainda, as mãos do homem da atualidade espelham smartphone. É difícil hoje imaginar o cotidiano sem um celular conectado e seus diferentes aplicativos. Do mesmo modo que o surgimento do compasso e de outros recursos de desenho mudou a forma de construir e entender conceitualmente determinado objeto matemático, os ambientes móveis de construção dinâmica também estão trazendo alterações ao aprendizado nos dias atuais. Este artigo traz ideias do campo da cognição, da linguagem e da neurociência para mostrar como elas podem orientar pesquisas com dispositivos com toques em tela; articula algumas dessas ideias a exemplos focados em formas de giro em uma tela ou com o próprio dispositivo; e ressalta as manipulações em tela como mais uma dimensão da cognição corporificada. Sublinha também a necessidade de incluir no pacote semiótico (escrita, fala, registros, construções em tela etc.) essa nova forma de interação e de manifestação e apropriação da linguagem. AbstractMobile devices with touchscreen are on the hands of all. Or rather, nowadays our hands mirror smartphone. It is difficult to imagine the daily lives without a connected cell phone and its different APP. In the same sense that the emergence of compass and other drawing resources changed the way we construct and conceptually understand a particular mathematical object, dynamic mobile environments are bringing for learning nowadays. In this article I bring ideas from the field of cognition, language, and neuroscience to show how they can guide researches with touchscreen devices. I articulate some of these ideas to examples focused on ways of turning on a screen or with the device itself. The article highlights the manipulations on screen as one more dimension of embodied cognition. It also emphasizes the need to include in the semiotic bundle (writing, speech, inscriptions, constructions on screen, etc.) this new form of interaction and manifestation and appropriation of language.

Dimensions to be considered in teaching, learning and research with mobile devices with touchscreen

“…Using a corded mouse may not be the same as using a wireless one. Each form of handling promotes different mappings in our brain, which can be related to sensitivity aspects, spatial features, (dis)continuity in handling, through (in)direct contact (Bairral, 2017).…”

“…Controlling manipulations on screen, on which our research group12 based some recent study, represents a new form of language manifestation and come to integrate our embodied cognition (Bairral, 2017). Although the possibility to touch the screen is not recent, the mobility and the type of sensitivity and performance offered by some devices are quite new and have made an impression on us.…”

“…Touching on the screen generates a whole net of different movements, combining themselves, often forming a multifaceted symbolic system (Bairral, 2017). Ubiquity and mobility in a tablet or smartphone imply a better understanding and interaction subjectenvironment and, in this sense, the expansive dimension of technology in the process of conceptual holding is still more in demand.…”

“…This flux, which can be represented pictorially, composed also with words and abstract symbols (not represented with simple images), can be called thought (Damásio, 2005). In the case of mathematical thinking, we need to consider that a concurrence of gesture + speech + construction-on-the-screen + touches + pictorial-register + movement-with-the-device + movement-with-the-body compose, with the same relevance, the linguistic-cognitive spectre of the subject (Bairral, 2017). Although manifestations through images are often difficult to be captured or analysed synchronically, we cannot value only written registers.…”

Dimensões a considerar na pesquisa com dispositivos móveis

“…Cada forma de manuseio promove em nosso cérebro mapeamentos diferentes. Esses podem ser de sensibilidade, de espacialidade ou de continuidade de manuseio direto no objeto ou a partir dele (Bairral, 2017).…”
