Over the years, much criticism against animal use for physiology teaching has been made. Hence, replacement by suitable alternatives has increased in several pedagogical approaches. This study examined students’ perceptions of animal versus virtual (video/computer) laboratory classes in physiological sciences associated with the effectiveness of the problem-based learning (PBL) hybrid curriculum. Three cohorts of medical students from the University of Ribeirão Preto, who participated in animal or virtual physiology classes or both, were asked to fill out a 5-point Likert questionnaire about knowledge acquisition/motivation, importance to PBL learning goals, skills acquired, need for animal use, academic formation, learning impairment, and alternative methods. We also assessed their grades in the final exam. A total of 350 students were included, in which 108 participated only in virtual classes, 120 only in practical animal laboratory classes, and 122 in both approaches. The majority agreed that the two methods improved their knowledge acquisition/motivation and helped to reinforce tutorial goals and to acquire skills. However, the cohort who experienced both approaches favored animal laboratory. Students believe animal use is needed and did not impair their learning. Conversely, their opinion about academic formation without animal laboratory classes was divided, as was whether this approach inspired them to seek alternative methods. Despite the different perceptions, there was no difference among the groups’ final grades (7.3 ± 1 vs. 7.2 ± 1 vs. 7.2 ± 2 for virtual or practical animal laboratory classes or both, respectively). Therefore, virtual activities are not as effective as animal use in the opinions of the students, but they are successful strategies in physiology learning that can be used in practical classes in a hybrid PBL curriculum.

Background: Effective assessments programs are a challenge in problem-based learning (PBL). One of the main principles of this educational setting is the Formative Assessment (FA). We hypothesized that students’ performance assessed by FA in tutorial sessions in a PBL curriculum is related to other summative assessments.Objective: To investigate the correlation among FA in tutorial sessions with grades obtained in Objective Structured Clinical Evaluation (OSCE) and Progress Testing (PT) to better understand the assessment process in PBL medical teaching approach and to predict student’s future performance.Design: An observational cross-sectional study was conducted comparing FA, OSCE and PT scores from 4th to 8th semester medical students. Correlation analyses were performed using pooled and separate data from the 4th and 8th semesters.Results: From the 5th to 8th semester, OSCE scores were smaller compared to the FA, while PT scores were lower in all stages. In the pooled data, the correlation analysis showed a significant positive relationship between grades on FA and OSCE, FA and PT and OSCE and PT. A significant correlation among the three assessments strategies was also detected in the 8th semester, but not in the 4th semester.Conclusions: Assessment strategies in PBL approach, including FA, OSCE and PT, have positive correlations, which increases as the medical course becomes more complex.
