Resumo


This work presents a game like educational software (courseware) to study metabolic pathways, calledDiagrama Metabolico Din^amico Virtual (DMDV) of Krebs Cycle. The experience acquired teachingwith the logical sequence tray games in the FFFCMPAs Biochemistry Course provides the beddingswith the use of this model as education method. With DMDV, students can assembly the sequenceof reactions that describe the desired metabolic pathway, create situational models which can guidehis/her choices, reduce the subject complexity of the scheme in knowledge construction presentingin a graphical way the current interrelations. Biochemistry teachers can use the present software inclassroom as well as distance classes. This product integrates multimedia resources extensively andis distributed in CD-ROM format. The virtual environment will make possible interaction of thestudent 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 rst group was composed by 11 students, who were more familiar with the content and answereda specic questionnaire to previously evaluate the software. The second group was formed by 24students regularly registered in the FFFCMPAs Biochemistry Course, who used the software as astudy method. The rst group considered DMDV of easy and pleasant navigation. The knowledgeevaluation of the second group students was made by a written test and the analysis of three conceptualmaps constructed by each one of them: one map before initiating the study with the DMDV, thesecond just after the study and the third one two months later. Every conceptual maps producedafter DMDV method showed an expansion of valid concepts if compared with the rst maps. Simplevisual comparison of maps shows that new elements where added. All students who passed throughthe experiment reached a greater than ve grade in the subjects written test. Current results suggestthe validity of the DMDV related method to metabolic pathway study.
