ABSTRACT
Nos últimos anos, tem-se observado nas instituições de ensino superior, públicas e particulares, uma grande dificuldade dos alunos da área da saúde na aprendizagem de Bioquímica. Este problema deve-se principalmente ao uso da abstração para descrever fenômenos que acontecem em nível molecular, além da exigência de conhecimentos básicos de química. Portanto, para tornar a disciplina de Bioquímica efetiva na formação dos nutricionistas é necessário adotar medidas focadas nas principais dificuldades dos alunos. É muito importante ressaltar a necessidade de uma análise do ensino de Bioquímica no curso de Nutrição de uma Instituição de Ensino Superior da rede particular, pois sua contribuição para a formação profissional é, quantitativamente, superior às públicas. Contudo, as reais condições de ensino/aprendizado vigentes têm sido pouco estudadas, do ponto de vista acadêmico. A presente pesquisa identificou as principais dificuldades dos alunos no aprendizado de Bioquímica e propôs alternativas para seu aprimoramento, usando como modelo de estudo a disciplina de Bioquímica no curso de Nutrição em uma Instituição de Ensino Superior da rede particular. Durante a pesquisa, foi traçado um perfil da instituição e dos estudantes, foram realizados questionários e testes, para investigar as principais dificuldades no aprendizado de Bioquímica. Concluímos que os alunos têm grande dificuldade com as representações simbólicas, problemas em compreender palavras novas, interpretar textos e gráficos. Então, foram realizados exercícios direcionados à melhora da compreensão das representações simbólicas, interpretações de textos e gráficos e a cada palavra nova o seu significado era explicado. Diante da necessidade de compreensão de um conceito químico, o assunto era abordado. Também foram realizadas provas em grupo, para que os alunos tivessem a oportunidade de discutir de forma ativa os problemas apresentados. Para avaliar a eficácia das intervenções foram realizados os...
In recent years, it has been observed that life science students in both private and public universities have great difficulties in learning biochemistry. This problem is due mostly to the lack of abstract thought, required for understanding phenomena at the molecular level, accompanied by lack of basic chemistry knowledge. Therefore to improve the effectiveness of biochemistry teaching it is necessary to adopt measures that address the main students' difficulties The analysis of biochemistry teaching in the Nutrition course of a private university is considered essential given that their student output is superior to public universities'. Despite of this, academic research on the actual teaching & learning conditions in private universities is limited. The current research used the teaching of biochemistry to Nutrition students of a private university as a case study. Profiles of the institution and students were drawn and questionnaires and tests carried out to investigate the main difficulties faced by students. We concluded that students have great difficulty in understanding symbolic representations, have problems in understanding new vocabulary and interpreting texts and graphs. Therefore, students were subjected to exercises aimed at developing the understanding of symbolic representations and text and graphics interpretation, with the meaning of each new word explained. Chemistry concepts were discussed as required. Assessments were held in small groups, to provide students the opportunity to actively discuss the issues being presented. To evaluate the effectiveness of these interventions the students were subjected to the same tests used to evaluate their difficulties . The visual literacy test showed considerable improvements in graphs interpretation and new vocabulary. A comparison of before and after evaluation sheets pointed that students were more satisfied with the learning experience following the interventions. Therefore we conclude that it...

El desarrollo de prácticas de laboratorio en el primer año de la carrera de Medicina se ha visto limitada por las carencias de reactivos, sin embargo, el escenario del policlínico universitario facilita su realización al estar disponibles los servicios del laboratorio clínico. Esta actividad docente concebida para la adquisición de hábitos y habilidades en procedimientos experimentales alejados de la vinculación básico-clínica tampoco es alcanzable en los nuevos modelos pedagógicos. Para lograr familiarizar a los estudiantes con su futuro desempeño profesional se realiza una investigación acción de tipo cualitativa cuyos objetivos se encaminaron a: identificar los procedimientos experimentales que se realizan en el escenario docente y que permiten tratar los contenidos de Bioquímica, elaborar la estructura metodológica para la vinculación básico-clínica mediante el desarrollo de prácticas de laboratorio orientadas a problemas de salud en la comunidad y comprobar el nivel de satisfacción de los estudiantes sobre el desarrollo de esta actividad docente al ser aplicado el diseño metodológico elaborado durante los cursos 2005-2006 y 2006-2007 en los policlínicos Norte del municipio de Sancti Spíritus, el de Guayos y de Fomento. Entre los resultados a destacar se encuentran que existe relación entre el contenido de Bioquímica y los complementarios con los procedimientos experimentales y de diagnósticos que se realizan en el laboratorio clínico del policlínico universitario factibles a la vinculación básico-clínica, se familiarizaron los estudiantes con problemas de salud presentes en la comunidad, lograron interpretar resultados de complementarios. Los estudiantes expresaron estar satisfechos con la metodología aplicada reconociendo que actividades de este tipo los motivan al estudio de la Bioquímica y su importancia en la formación como futuros médicos generales e integrales.
The development of laboratory practices during the first year of the Medicine career undergoes the lack of reagents; however, the university polyclinic setting allows it's carrying out due to the availability of the clinical laboratory. This teaching activity conceived for the acquisition of habits and abilities in experimental procedures remotes from the basic-clinical linking neither is achievable in the new teaching models. To obtain the students familiarization with their future professional performance, authors made a research action of qualitative type whose objectives aimed at to identify the experimental procedures applied in the educational setting allowing treating the Biochemistry contents, to design the methodological structure for basic-clinical link through the development of laboratory practices directed to community health problems and to verify the student's satisfaction level on the development of this teaching activity when the methodological design was applied for 2005-2006 courses and 2006-2007 in the Northern polyclinics of Sancti Spíritus, Guayos and Fomento municipalities. Among the more significant results achieved is the relation between the Biochemical content and the complementary ones using the experimental procedures y of diagnosis performed in the clinical laboratory of university polyclinic feasible to basic-clinical linking, the familiarity of students with the health problems present in the community and interpretation of complementary results. The students expressed their satisfaction with the applied methodology recognizing the this type of activity motivates them to Biochemistry study and its significance in the practical training as future integral general physicians.
