Construção e validação de um aplicativo para o ensino e aprendizagem de anatomia radiológica

Abstract

Radiological anatomy is one of the disciplines of health education and its knowledge in clinical practice is necessary in order to obtain an adequate interpretation of imaging exams, issuing a correct diagnosis to the patient. In recent years, there have been increasing efforts to integrate pre-clinical and clinical modules with anatomicalradiological knowledge. Thus, Digital Educational Technologies (DTE), such as mobile applications and interactive games, are increasingly inserted in everyday education, supporting teaching practice, in line with the conventional methodology already consolidated. The present study aims to develop a quiz-like application for teaching and learning radiological anatomy. Thus, a descriptive, quasi-experimental study with a quantitative approach was carried out. For the construction of the application, the steps of the methodological assumptions were followed, due to the cohesion with the research objectives. The phases were: construction, where the analysis, design, and development of the application were performed. In this process a database with questions related to radiological anatomy was built and developed in the Adobe Air web platform with the Action script 3.0 programming language for the creation of the quiz. For validation, 15 expert judges were selected who were professors in the anatomy area and participated in research groups, all with experience in teaching morphology. The validation of the application in relation to its appearance and content showed that the content is scientifically correct, that the educational application addresses issues essential to the knowledge of users with CVI (Content Validity Index) equal to 0.93. Regarding the educational application's navigability, the judges attested that it is intuitive and that the error and success messages are appropriate, obtaining a CVI of 0.85. Therefore, a total overall CVI of 0.87 was observed. However, it was observed that there were no statistically significant differences in relation to the students' knowledge during the pre-test and the post-test.in the radiological anatomy course held at the Federal University of Ceará in the Department of Morphology. On the other hand, the students' evaluation of the functionality, content, and practicality for teaching gave a positive assessment of all the questions presented regarding QuizAR. Finally, the validation stage showed that the application is a valid technology that can be used for teaching radiological anatomy in undergraduate courses.
