The Validity of a Visual Basic Program in Learning Cone Beam Computed Tomography versus the PowerPoint Slides

Abstract

Aims: the purpose of this study was to evaluate the validity of specially designed computer assisted learning (CAL) Visual Basic program containing images with multiple choice questions (MCQ) for learning the basics of CT and CBCT compared to lecture supplemented with PowerPoint presentation only. Methodology:The software contained one hundred images obtained from textbooks and internet web sites, the images included the basic principles of CT and CBCT, normal anatomical landmarks, caries, periapical granuloma, cyst and tumor interpretation. 30 postgraduate internship students' participated and divided into two groups after attending a guiding lecture about the cone beam computed tomography including the study images, group I were given the program CD while group II were allowed to review the lecture only. After 2 weeks, both groups had OSPE exam.Results: it showed statistically significant mean student's score in group I receiving the program CD after lecture compared to the other group II (traditional method only) Conclusion: The use of CAL Visual Basic program enhances the learning of the basics of CBCT
