Resumo Neste artigo buscamos identificar e compreender as características do contexto formativo em Matemática de estudantes quando produzem jogos digitais e dispositivos robóticos destinados ao tratamento de sintomas da doença de Parkinson. Norteados pelas ideias da metodologia qualitativa de pesquisa, interagimos com alunos do Ensino Médio visando a construção de um jogo eletrônico com dispositivo robótico, chamado Paraquedas, destinado a sessões de fisioterapia de pacientes com Parkinson. Os alunos foram estimulados a propor e desenvolver ideias em ambientes voltados à experimentação e invenções eletrônicas para beneficiar pessoas em sociedade. Os dados foram analisados à luz dos pressupostos teóricos do Pensamento Computacional e da Matemática Crítica e consistem de discussão-análises do desenvolvimento científico-tecnológico, colaborativo-argumentativo e inventivo-criativo de tecnologias, indo além dos muros da sala de aula de Matemática. Como resultado, identificamos as seguintes características do contexto formativo em Matemática: independência formativa; imprevisibilidade de respostas; aprendizagem centrada na compreensão-investigação-invenção; e conexão entre áreas de conhecimento. Compreendemos que tais características se originam e mutuamente se desenvolvem dinâmico e idiossincraticamente nas concepções de planejamento, diálogo e protagonismo dos sujeitos, os quais fomentam a exploração de problemas aberto e inéditos de Matemática em-uso e descentralizam a formalização excessiva do rigor de objetos matemáticos como ponto nevrálgico à formação em Matemática.

Principles and Standards for School Mathematics (NCTM 2000) emphasizes the goal of computational fluency for all students. It articulates expectations regarding fluency with basic number combinations and the importance of computational facility grounded in understanding (see a summary of key messages regarding computation in Principles and Standards in the sidebar on page 156). Building on the Curriculum and Evaluation Standards for School Mathematics (NCTM 1989) and benefiting from a decade of research and practice, Principles and Standards articulates the need for students to develop procedural competence within a school mathematics program that emphasizes mathematical reasoning and problem solving. In fact, learning about whole-number computation is a key context for learning to reason about the baseten number system and the operations of addition, subtraction, multiplication, and division.

Nowadays, the growing complexity of mathematical and computational modelling demands the simplicity of mathematical and computational equations for solving today’s scientific problems and challenges. This paper presents combinatorial geometric series, innovative binomial coefficients, combinatorial equations, binomial expansions, calculus with combinatorial geometric series, and innovative binomial theorems. Combinatorics involves integers, factorials, binomial coefficients, discrete mathematics, and theoretical computer science for finding solutions to the problems in computing and engineering science. The combinatorial geometric series with binomial expansions and its theorems refer to the methodological advances which are useful for researchers who are working in computational science. Computational science is a rapidly growing multi-and inter-disciplinary area where science, engineering, computation, mathematics, and collaboration use advance computing capabilities to understand and solve the most complex real-life problems.

The paper is written to demonstrate the applicability of the notion of triangulation typically used in social sciences research to computationally enhance the mathematics education of future K-12 teachers. The paper starts with the so-called Brain Teaser used as background for (what is called in the paper) computational triangulation in the context of four digital tools. Computational problem solving and problem formulating are presented as two sides of the same coin. By revealing the hidden mathematics of Fibonacci numbers included in the Brain Teaser, the paper discusses the role of computational thinking in the use of the well-ordering principle, the generating function method, digital fabrication, difference equations, and continued fractions in the development of computational algorithms. These algorithms eventually lead to a generalized Golden Ratio in the form of a string of numbers independently generated by digital tools used in the paper.
