Resumo
A genética é uma ciência em constante evolução e vem sendo alvo de interesse pela mídia. Com os avanços evidenciados na genética no nosso dia a dia, o sistema educacional brasileiro tem necessidade de adequar-se à realidade, aproximando a escola dos novos conceitos. Assim, tendo em vista a importância da genética para a alfabetização científica dos alunos, o objetivo do presente trabalho foi, através de uma pesquisa qualitativa, com o auxílio de questionários, verificar qual o conhecimento mínimo de genética básica dos concluintes do ensino médio, e também dos graduandos de ciências biológicas dos anos de 2004 e 2005 que ainda não haviam cursado a disciplina de genética. De acordo com o exposto no presente trabalho, fica evidente e indiscutível, a importância da melhoria das técnicas de ensino de genética. Os alunos do ensino médio demonstraram certa dificuldade para trabalhar questões que exigem estruturação das respostas, os mesmos procuraram respondê-las da maneira mais simples possível e com o minímo de palavas, prejudicando muitas vezes o entendimento de seus textos. Os conteúdos abordados mostraram-se em alguns casos, desconhecidos pela maioria - devido à quantidade de alunos que deixaram de responder a algumas questões básicas, tais como Leis de Mendel, mitose e meiose, herança e sexo, teoria cromossômica e herança biológica. Com relação aos graduandos de Ciências Biológicas, a aprendizagem de genética encontra-se também, longe de ser satisfatória, visto que os mesmos já passaram pelo vestibular...
Genetics is a science in continuing evolution and it has been object of interest of the media. The Brazilian Educational System needs to adjust itself to reality, linking school to the new concepts, because the advances evidenced by genetics nowadays. Hence, because the importance of genetics to the scientific knowledge of students, the purpose of this study was, by means of a qualitative research and the use of questionnaires, to verify what is the minimal knowledge about genetics presented by senior high school students and undergraduate students of Biological Science during academic years of 2004 e 2005, which ones had not attended a course in genetics yet. According to the results shown here, it is evident and unquestionable the importance of improvements in teaching techniques on genetics. Senior high school students showed some difficulties in solving questions that required structured answers. They tried answering questions as a simple way as possible, using few words, many times, damaging the comprehension of their texts. The contents approached were unknown by most of the students - whereas a huge amount of them not answered basic questions, like those related to Mendel's Laws, mitosis, meiosis, heredity, gender, chromosomal theory and biological heredity. In regard to undergraduate students, the learning about genetics is also far from to be satisfying, considering that they have already taken a college entrance exam, which one is considered as a seletion process worried about content, so these students are expected to have a better comprehension about basic genetics. The differences seen among the three groups analyzed (senior high school students, undergraduate students of Biological Science during the academic years of 2004 e 2005) are not significant and refer...
