Interpretação geométrica dos signos das razões trigonométricas com Geogebra

Abstract: O ensino da Trigonométrica caracterizou-se por um enfoque algébrico, o que tem feito de seu estudo um processo memorístico e mecânico. Um conteúdo onde se pode evidenciar o anterior é o dos signos das razões trigonométricas que costuma se abordar através do uso de regras mnemotécnicas, ação que limita seu entendimento. Com a intenção de apoiar à superação deste problema, neste trabalho descreve-se o desenho de um recurso elaborado com o software GeoGebra e sua aplicação em uma sequência para analisar e dotar s… Show more

“…In this extract of the transcription, there is an expression that cannot be categorized with any of the types of connections proposed a priori in the theoretical foundation, which led us to investigate this type of expressions "the law of the ear" and it was found that refers to mnemonics used by humans to memorize or remember procedures more quickly (Balbuena & Buayan, 2015;Bor & Owen, 2007;Díaz-Urdaneta & Prieto-González, 2015;Drushlyak et al, 2021;Fiallo, 2010;Hoffmann, 2018;Keller, 2016;Márquez-García, 2013;Nelson et al, 2013;Reyes-Gasperini et al, 2014;Vargas & Urzúa, 2018). Therefore, in this research, the new category for ETC is proposed as MT connection based on mnemonics, understood as the relationship established by the subject between a mnemonic rule (often a familiar resource) and a mathematical object, rule, or mathematical procedure to memorize and use strategically more easily.…”
