STUDENTS’ DIFFICULTIES IN BIOCHEMISTRY LEARNING ANALYZED THROUGH AN ON LINE ACADEMIC DROP-IN CENTER

F. Schoenmaker, B.B. Torres

Resumo


The biochemistry discipline integrates the curriculum of all graduation courses on
the Biological Area and is a basis for other disciplines. The students’ difficulties in
this discipline are already widely recognized. To investigate these difficulties, we
created a drop-in on line service that has two purposes: (1) To give support to
students’ learning by answering their questions and solving their problems
whenever they appear and (2) to analyze the questions presented, as a strategy to
diagnose the most prevalent difficulties. After two semesters of this service on line,
217 questions were received and answered. There were few conceptual questions
being the majority related to problems and exercises. The most frequent questions
dealt with cell metabolism (54,4%), mainly lipid metabolism and aerobic
metabolism; basic concepts (11,5%) such as about amino acids and buffer, protein
structure (8,3%) and enzymes (7,8%). These percentages are correlated to the
number of hours dedicated to each subjects in the disciplines. The main difficulties
founded were: integration of metabolic processes in different tissues, induction of
energy reserve oxidation, reciprocal regulation between glycolysis and
gluconeogenesis. We suppose that the lack of laboratory practice difficults the
learning of basic concepts. A more in-deep analysis will be necessary to
investigate the causes of the pointed difficulties.
