Abstract

Background: There is currently little evidence of a theoretical base for the development and delivery of multimedia teaching in medicine. In this thesis I have; (1) reviewed the principles of adult learning and Instructional Design (ID) (2) proposed an evidence based model for a novel multimedia learning framework (3) developed the model (4) delivered the program to medical students who evaluated its functionality and content and (5) identified learning points for future investigators. Method: Interview style scripts were authored, recorded and integrated to produce “AnswersIn Gastroenterology”. A focus group based pilot study tested the robustness of the program and need for modification. Following a survey of medical student access to multimedia computers, AnswersIn was made available on the university server. The technical challenges of web-delivery were documented and the program made available to four consecutive student groups during their gastroenterology blocks. At the end of each block, students formatively evaluated the resource via a questionnaire. Additionally, the variety of data available using a web-tracker was examined as well as the effect upon usage of a series of advertising emails. Results: 8.5 hours of content were developed. The focus group recommended modifications which were implemented. The survey demonstrated that medical students have high levels of access to multimedia computers. Despite problems encountered during the implementation phase, a total of 178 students had access over four blocks. 21 percent considered AnswersIn as an alternative to lectures and 33 percent indicated that they would use AnswersIn as their main learning resource. Students gave reasons why they continued to favour traditional teaching methods but almost all stated that they would like to see AnswersIn extended to other subjects. Web tracking demonstrated that advertising increased usage. Conclusion: AnswersIn is a novel framework formulated using principles of adult learning and Instructional Design. Formative assessments indicate that students respond favourably to its introduction and its usage can be influenced by advertising.
