In the last decades with the advance of the scientific and technological development, Biology is becoming the base for the sprouting of these new processes. The dilemma that involve the subjects of Bioethics such as: abortion, euthanasia, genetics, trunk cells , research involving human beings and animal and public health, always leave of the biological knowledge. Being thus, this study it has as objective, to identify if the ethical aspects of the subjects that the Bioethics studies, they are argued in the course of graduation degree in Biology at UFAL. The methodology mention the research focus on of qualitative nature, being used the case study as methodological boarding. The data had been gotten through closed questionnaires applied to the professors and the students of the last year of the 2005 group, of the Biological course of Sciences at UFAL. The analysis of the data discloses, that a convergence for the most complex subjects of the ethical point of view and that exists exactly thus, the ethical aspect is not argued in classroom. In this way, the importance of the promotion of the debates of the subjects is verified that the Bioethics studies inside of the classroom, so that, this way it comes to contribute for the moral development and the ethical formation of the future professors of the course of Biological Sciences at UFAL. / Fundação de Amparo a Pesquisa do Estado de Alagoas / Nas últimas décadas com o avanço do desenvolvimento científico e tecnológico, a biologia vem se tornando à base para o surgimento destes novos processos. Os dilemas que envolvem os temas de Bioética como: aborto, eutanásia, genética, células tronco, pesquisas envolvendo seres humanos e animais e saúde pública, partem sempre do conhecimento biológico. Sendo assim, este estudo tem como objetivo, identificar se os aspectos éticos dos temas que a Bioética estuda, são discutidos no curso de graduação de licenciatura em Ciências Biológica da Universidade Federal de Alagoas (UFAL). A metodologia utilizada refere-se à pesquisa de natureza qualitativa, sendo utilizado o estudo de caso como abordagem metodológica. Os dados foram obtidos através de questionários fechados aplicados aos professores e aos estudantes do último ano da turma de 2005, do curso de Ciências Biológica da UFAL. A análise dos dados revela, que existe uma convergência para os temas mais complexos do ponto de vista ético e que mesmo assim, os aspectos éticos não são discutidos em sala de aula. Deste modo, verificase a importância da promoção dos debates dos temas que a Bioética estuda dentro da sala de aula, para que dessa forma, venha a contribuir para o desenvolvimento moral e a formação ética dos futuros professores do curso de Ciências Biológicas da UFAL.

The reasons for the decline in students' interest in science have been studied for the last decades. The key question is how to stimulate this interest and motivate students and pupils to study science. Part of this thesis was testing the influence of practical courses on upper secondary school students' motivation toward studying biology. To start with, it was found out how many practical courses were taught for each biology topic at Czech upper secondary schools. Molecular biology and genetics emerged as one of the topics with the lowest number of practical courses. Therefore, molecular biology practical courses have been proposed and tested. It was shown that these practical courses can increase students' motivation scores. The possible influece of age, gender and number of practical courses during biology lessons on motivation was tested as well. Motivation of Czech students was compared to motivation of New Zealand students. Younger students and boys were more motivated to study biology in both countries. New Zealand students were more motivated than Czech students. Motivated students like the participants in the Biology Olympiad, Students' Professional Activities, biology summer course and optional biology courses were used to describe the origin of their motivation toward biology.
