The progress in the areas of molecular biology and biotechnology has been demonstrating the importance of the teaching-learning of those subjects to students and teachers of the elementary and high school as well as to the society in general.In this sense, the Scientific Dissemination Coordination of CBME has as objective contributes for the dissemination and learning of techniques and basic concepts in that area of the knowledge, in order to awake in the public the scientific interest and the critical sense related to these advances.With the goal to offer elements for the elaboration of activities addressed to science teachers of elementary and high school, a survey of their conceptions on science and biotechnology was made. A questionnaire was applied to 30 teachers that participated in updating courses and training, being that 13 teachers belonged to the region of São Carlos city (SP), 8 belonged to the region of Campinas city (SP) and 9 belonged to Fortaleza city (CE).The questionnaire was applied to the teachers in the beginning of the courses and it was composed of different types of questions, which allowed capturing their personal reflections about science, their knowledge on basic concepts of cell and molecular biology, and their opinions about the applications of the biotechnology.In the analysis of the question What you think about using the modern biotechnology in the production of foods to increase its protein content, in order to turn it larger or to change its taste?, 57% of the teachers agreed partially that this application is useful for the society, 52% agreed totally that the application is morally acceptable while 70% totally disagree as for the encouragement of this application.Some conflicts presented in the registered answers reflect, in certain way, the conflict shown by the academic and scientific communities, as for the ethical aspects of some applications such as transgenic foods, genetic manipulation in animals and the possibility of human cloning.
The current evolution of the science and technology generated a demand in the teachers' formation that needs constant updating. In that sense, CBME has been elaborating courses and workshops to update teachers of Sciences and Biology involving current themes. The activities on Molecular Biotechnology were elaborated, especially on restriction enzymes and gel electrophoresis. Thirtyseven teachers of public schools participated in the activities. Firstly, it was made an experiment demonstrating the digestion of a plasmidial DNA by two restriction enzymes (DraI and EcoRI), with the subsequent application in gel, in order to elucidate the electrophoresis technique. After the demonstration, simple and practical exercises were distributed to the teachers to simulate those processes using paper ribbons and charts, being concluded with an exercise of a paternity test. A questionnaire was applied as an evaluation tool and from the teachers' answers it was observed, among other data, that 100% of the teachers classified the activities as interesting, 43% classified the thematic as actual, 22% defined it as appropriate to their school reality and 19% pointed it as a subject on which they have doubts. Also, it was observed that the teachers felt confident dealing with the most specific subjects, when relating it with the daily events and visualizing a possibility of didactic transposition of those themes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
