Abstract
This article presents a geometric and algebraical approach to teach the concept of elasticity for undergraduate students with different levels of knowledge in mathematics and pointing out why it is necessary to introduce it from the idea of he slope of a function. To achieve this objective a short review of the literature of the main properties associated with elasticity is carried out, without separating them from their historical development, to illustrate a way of presenting the concept in a discrete or continuous way and using geometric arguments or algebraic expressions. Due to the flexibility of the concept, and taking into account the previous knowledge of the student, it is concluded that this approach is a more adequate way to teach the concept. Este artigo apresenta uma abordagem algébrica e geométrica para ensinar o conceito de elasticidade a estudantes de graduação com diferentes níveis de conhecimento de matemática e aponta por que é necessário apresentá-lo a partir da ideia da pendente de uma função. Para atingir esse objetivo, foi feita uma revisão breve da literatura das principais propriedades associadas à elasticidade, sem separar estas do seu desenvolvimento histórico, para ilustrar a maneira de apresentar o conceito de uma forma discreta ou contínua, e usando argumentos geométricos ou expressões algébricas. Dada a flexibilidade do conceito e considerando o conhecimento prévio do estudante, concluiu-se que essa abordagem é mais adequada para ensinar o conceito.
