FELICIANO PIRES, Deborah; DE FARIA SILVA, Juliana Rocha  and  DE OLIVEIRA BARBOSA, Mayara Lustosa. Station rotation in the embryology teaching: a proposal combining three-dimensional models and blended learning. Rev. estud. exp. educ. [online]. 2021, vol.20, n.43, pp.415-436. ISSN 0718-5162.

The embryology content taught for K-12 students has many unknown nomenclatures, complex morphologies, and details. The use of three-dimensional (3D) models to teach the content allows handling and macroscopically view the structures formed in embryonic development. This research aimed to develop and evaluate 3D models for teaching embryology, using the Station Rotation Model (SRM) of Blended Learning as an application methodology. To this end, students initially answered to a pre-test to verify previous knowledge. Subsequently, a control group (CG) had a conventional class, and an experimental one (EG), had a class with 3D models applied with the SRM, in which the students should go through 3 stations with activities to be developed using the models. In the next class, the groups performed a post-test. An opinion and knowledge questionnaire was also answered 5 months after the methodology. When evaluating the pre-tests, it was identified that CG had higher scores than EG (p <0.05). When comparing only the post-tests, there was no significant difference. However, when comparing pre and post-test separately for each group, we observed a statistically significant difference between the EG tests (p <0.05) but not for the CG tests, demonstrating that there was a higher yield for the EG. In the last questionnaire, we verify that the EG approved the methodology, as well as had greater mnemonic retention in comparison with CG students. From the results, it is possible to infer that the 3D models used in the SRM were didactic, motivational, and improved the students' performance.
