A utilização de ferramentas e métodos inovadores e tecnológicos associados aos conceitos teóricos favorece o ensino-aprendizagem. A pesquisa descreve resultados que retratam mudanças que são percebidas nos estudantes durante e após a utilização das ferramentas e demonstram a posição do estudante como sujeito ativo no processo de ensino-aprendizagem. A partir de um movimento de transformação das estruturas disciplinares, evidencia-se a correlação entre a busca de maior participação ativa e crítica dos estudantes quando se tem um dinamismo nas aulas. Conclui-se que as vantagens em termos de aproveitamento, desempenho académico e satisfação dos estudantes envolvidos quando comparado com os métodos tradicionais de ensino, foi de aproximadamente 93% de aceitação, o que expressa um aumento significativo no desempenho dos alun...

This paper describes the use of Tradescantia pallida as a bioindicator, to verify its sensitivity to gamma radiation from a <sup align="right"> 137 Cs source and to monitor places of low doses of ionising radiation in tropical climates. Specimens of the T. pallida were exposed to radiation for a period of 24, 36 or 48 h. The results show that the biological system offers a good alternative for biomonitoring of gamma radiation at low doses and is an excellent mechanism for fast and simple acquisition of data, and thus is capable of anticipating abnormalities produced by genotoxic agents, favouring its use in monitoring in nuclear installations.
