Lectures and collaborative working improves the performance of medical students.

The teaching-learning process is complex and requires continuous research and dedication. Research has been important to prove that student achievement can improve when active methodologies are properly implemented, either in isolation or integrated with a short lecture. The purpose of this work was to evaluate the performance and perception of first-year medical students subjected to a protocol involving the integration of a short lecture and collaborative compilation of portfolios on the topic of digestive physiology. After the lectures and elaboration of the portfolios, the students completed two tests: cognitive monitoring test (CMT) and integrative cognitive test (ICT), and then, they gave their opinions of the strategy. For CMT, the percentage of grade exceeding 7.0 was higher for the group who performed the portfolio activity, compared with the group who did not undertake the activity, and there was a lower percentage of incorrect answers among the portfolio group students, compared with the group that did not perform the activity. For ICT, the percentage of grades exceeding 7.0 was higher for the students who used the portfolio, compared with those who did not perform the activity, and there was also a reduction in incorrect answers among students who performed the portfolio activity, compared with those who did not perform the activity. The combination of short lectures and collaborative group work using a portfolio improved the grades obtained for digestive physiology. Most of the students believed that the collaborative work contributed to their learning about digestive physiology. In addition, most of them were comfortable working in their groups and did not feel dominated by other group members.
