Introduction: Mobile learning offers several benefits, such as new learning environments. We developed and validated a smartphone application for orthopedics and traumatology residents in an attempt to assist their study and, consequently, pass the Board of Orthopedics and Traumatology Exam. Methods: quantitative study, aimed at the validation of a mobile application. It was developed for the iOS® and Android® platforms, in the Portuguese language, and free of charge. 132 participants, divided into three groups, used the tool. A validated questionnaire - System SUS Scale (SUS) - and a questionnaire created by the authors (properly validated) were used to assess the practicality and viability of the application as a learning tool. The mode, the absolute frequency and the percentage of the studied variables were crossed by Fisher's test or Pearson's chi-square test. Results: of the 132 participants, 55.3% have iOS®. All participants said they had already used an application on their smartphones, whereas 6 (4.5%) mentioned never having used applications for academic purposes (p value <0.001). 100% said it was a useful technology in the resident's theoretical development. 124 (93.9%) agreed it was an auxiliary learning method for orthopedic doctors in general. An average SUS score of 84.2 (SD 10.8) was obtained with a margin of error of 1.9. The SUS score varied between 82.4 and 86.1 (95% CI). Cronbach's alpha coefficient was 0.797. Conclusion: the developed application was successful in the tests performed and can be an alternative in medical education in the orthopedic area.

As metodologias de ensino têm apresentado mudanças expressivas no decorrer do século XXI. Este estudo avaliou o impacto de um aplicativo contendo vídeos simulados de psicopatologia. Realizou-se um estudo caso-controle composto por acadêmicos de Medicina. Na avaliação comparativa, utilizou-se uma prova descritiva, além do System Usability Scale (SUS). A amostra era composta por 16 alunos do grupo caso, com acesso ao aplicativo, e 82 pessoas do grupo intervenção. O grupo caso obteve escore médio de 4,7, frente à nota média de 3,2 do grupo controle (p=0,00017). Os resultados dos dados avaliados pela escala SUS demonstram uma boa avaliação de usabilidade. Assim, a utilização do aplicativo apresentou repercussões positivas para o aprendizado, sendo um instrumento útil e de boa usabilidade a ser acrescentado às demais metodologias de ensino.
