Sonographer University: A Hands-On Training Course for Adult Sonographers Performing Pediatric Echocardiography

Objective: Children with critical congenital heart disease (CHD) often present in remote areas with life-threatening illness. Although performing complete pediatric echocardiograms requires significant training, remote locations necessitate sonographers with limited pediatric experience screen for CHD. The Sonographer University (SU) was designed to improve comfort in adult sonographers scanning children and recognizing CHD. Methods: The SU consisted of lectures, multimedia case studies, roundtable discussions, pathology stations, and hands-on scanning of 20 volunteer pediatric patients with either normal or diseased hearts. Topics included an overview of critical congenital heart lesions, crucial views for each defect, and pitfalls in imaging children. Results: Forty-four participants completed the SU seminar. In pretest assessment, approximately two-thirds said they were currently required to scan children. Participants’ comfort level sonographically scanning children and recognizing CHD improved substantially. A posttest showed that the course improved participants’ skill, knowledge, and confidence with pediatric studies. Conclusion: The SU seminar helped sonographers from remote areas to develop improved recognition of CHD, confidence in pediatric scanning, and methods for obtaining assistance with imaging a critically ill child.

An Evaluation of Use of Multimedia Case Studies to Improve an Introduction to Information Technology Course

For college graduates to be successful in today’s global economy there has been an increasing demand for them to possess business knowledge as well as technical knowledge. To meet the demand, curriculum designers have sought to integrate new technologies, applications, data, and business functions into classrooms so that non-information technology (IT) majors can realize the benefits of IT. This paper discusses the results of research conducted on the use of multimedia case studies to address the curriculum designers’ challenge. The authors have found that students, who are taught using multimedia case studies, perceived a comparatively greater improvement in their higher-order cognitive skills, ease of learning, team working skills, attitude toward information technology, and self-efficacy. This suggests a need for further research into adopting such instructional materials for teaching non-IT majors and for developing other innovative instructional materials.
