Challenge
Faced with an extensive amount of course content and medical information, medical students seek study aids for knowledge management and retention.

Students would benefit academically if there were an on-demand resource for review of previous lectures and a reference for explanations of complex content areas. A versatile technology would also aid students' varied learning styles. Our response was the configuration of streaming media to deliver and archive medical school lectures.


Solution
Video Library
First and Second Year lectures are recorded on a daily basis. The streaming versions are available online as password-protected videos and podcasts. The videos are catalogued in a easy-to-navigate interface according to class year, main course, and course section.

We examine instructional technologies to complement traditionally delivered lecture materials. Our work addresses the needs of students concerned with mastery of complex concepts and information overload.

Posted chronologically, the lectures are also searchable by key word, lecture title, course, and instructor. The audio versions are formatted as mp3 files and tagged for classification in students' media players by lecture title, instructor and date.

Lecture Archives
The lecture archives are designed as an annotated and searchable multimedia database of First and Second Year medical school lectures delivered from 2003 to 2007. This repository allows students and faculty to access content according to key words and topics, instructor, lecture title, lecture date, and specific course.

Benefits
As a supplement to traditional delivery methods of medical school content, streaming technologies benefit both medical students and faculty.

Some advantages of streaming media are:
  1. Meets the expectations of students who are increasingly reliant on digital and mobile technologies for work and school

  2. Aids management of information overload by providing a record of course material in a web-based delivery system within a searchable database

  3. Adds a dimension to traditional course instruction by offering the option to review complex concepts or as a reference tool on key points

  4. Supports student preparation for comprehensive testing, such as the Board exams

  5. Provides faculty with archived versions of lecture content as reference for curriculum changes and updates
