O trabalho apresenta experiência de uso de software educacional, para estudo de umarota metabólica, denominado Diagrama Metabólico Dinâmico (DMDV) do Ciclo de Krebs. A experiênciafoi realizada com dois grupos distintos de alunos. O primeiro grupo composto por 11 monitores deBioquímica, analisou a operacionalidade do software, respondendo a um questionário específico,considerarando o DMDV de fácil navegação e agradável ao uso. O segundo grupo foi formado por 47alunos matriculados na disciplina de Bioquímica da FFFCMPA5 e subdivididos nos grupos A e B. Ogrupo A utilizou o software como método de estudo e o grupo B, considerado grupo controle, utilizouversão DMD (papel). A avaliação do conhecimento dos alunos do segundo grupo foi feita por uma provaescrita e pela análise de três mapas conceituais construídos por cada aluno: o primeiro antes de iniciaro estudo, o segundo após o estudo e o terceiro após dois meses do estudo. Todos os mapas conceituaisconstruídos após o uso do DMDV ou do DMD indicaram expansão de conceitos em relação aos mapasiniciais. Todos os alunos alcançaram nota superior a 5 na prova escrita. Os resultados apresentadossugerem a validade do uso do o método do DMDV para o estudo de uma rota metabólica
This work presents a game like educational software (courseware) to study metabolic pathways, called Diagrama Metabólico Dinâmico Virtual (DMDV) of Krebs´Cycle. The experience acquired teaching with the logical sequence tray games in the FFFCMPA´s Biochemistry Course provides the beddings with the use of this model as education method. With DMDV, students can assembly the sequence of reactions that describe the desired metabolic pathway, create situational models which can guide his/her choices, reduce the subject complexity of the scheme in knowledge construction presenting in a graphical way the current interrelations. Biochemistry teachers can use the present software in classroom as well as distance classes. This product integrates multimedia resources extensively and is distributed in CD-ROM format. The virtual environment will make possible interaction of the student with the environment and with colleagues and teachers, through tools as chats and forum. Experience with the use of this method was carried through with two distinct groups of students. The first group was composed by 11 students, who were more familiar with the content and answered a specific questionnaire to previously evaluate the software. The second group was formed by 24 students regularly registered in the FFFCMPA´s Biochemistry Course, who used the software as a study method. The first group considered DMDV of easy and pleasant navigation. The knowledge evaluation of the second group students was made by a written test and the analysis of three conceptual maps constructed by each one of them: one map before initiating the study with the DMDV, the second just after the study and the third one two months later. Every conceptual maps produced after DMDV method showed an expansion of valid concepts if compared with the first maps. Simple visual comparison of maps shows that new elements where added. All students who passed through the experiment reached a greater than five grade in the subjectś written test. Current results suggest the validity of the DMDV related method to metabolic pathway study.
This abstract reports the use of concept maps applied to the evaluation of concepts learned through the use of an educational software to study metabolic pathways called Diagrama Metabólico Dinâmico Virtual do Ciclo de Krebs(DMDV). Experience with the use of this method was carried through with two distinct groups of students. The first group was composed by 24 students (in 2003) who used DMDV during the classes (computer room). The second group was formed by 36 students (in 2004) who could access DMDV software anytime through the intranet. The construction of the conceptual map by the student permits the representation of knowledge, the mental processes that were absorved and the adaptation during the study, building new mental schemes that could be related to the concept of reflexioning abstraction (Piaget, 1995) during the process of operation with these concepts. The evaluation of knowlegde was made by the analysis of three conceptual maps constructed by each one of them: (a) one map before initiating the study with DMDV, (b) the second just after the study and (c) the third one two months later. We used the following criteria for the analysis: predominance of associative over classificatory character; correct concepts and relationships; coherence; number of relationships; creativity and logic. The initial maps showed that all students had some previous mental scheme about the proposed concept. All final concept maps showed an expansion of the concepts as compared to the initial maps, something which can be seen even by a mere glance at the size of graphics. A purely visual comparison between the maps indicated that new elements have been added. The associative character has been shown to predominate as compared to the classificatory one. The results obtained suggest the validity of using concept maps as a strategy to monitor the cognitive process, both by the teacher and by the student him/herself.
