Evaluation of a computer-based program for teaching cardiac anatomy.

RATIONALE AND OBJECTIVES: The authors determined to what extent a computer-based program could enhance or substitute for cadaver dissection in teaching cardiac anatomy to first-year medical students. METHODS: First-year medical students (n = 175) were randomized into four groups. Group 1 (control) received no instruction, group 2 participated in cardiac dissection, group 3 viewed the computer application, and group 4 performed cardiac dissection and then viewed the computer application. Each group was tested with 10 ultrafast computed tomographic static images and 8 cardiac cadaver specimens. RESULTS: The computer program plus dissection was superior to either the computer program alone or dissection alone; however, the results varied according to the subtest used to assess the outcomes. CONCLUSIONS: Cardiac computer instruction after dissection resulted in dramatically improved image testing performance. However, computer instruction should not replace dissection for teaching cardiac anatomy.

The instructional effectiveness of a radiology multimedia textbook (HyperLung) versus a standard lecture.

RATIONALE AND OBJECTIVES: Information overload is a significant problem for the modern radiologist. This prospective study compares the instructional effectiveness of a multimedia textbook (HyperLung) with a lecture. HyperLung is a radiologic multimedia textbook about imaging diffuse lung disease created using a multimedia authoring tool, the Annotator (the University of Iowa Second Look Computing, Iowa City, IA), on the Apple Macintosh computer (Apple Computer, Cupertino, CA). METHODS: Forty-nine staff physicians and residents in the Department of Radiology were randomized to receive instruction either by HyperLung or by a lecture. The instructional content was the same in both groups, and both groups were tested before and after instruction. The actual time spent in each instructional situation was recorded. RESULTS: The instructional effectiveness of the multimedia textbook and lecture was equal. The instructional efficiency of HyperLung was only 60% of the lecture. Users of the multimedia textbook found it enjoyable and straightforward to use. CONCLUSIONS: Multimedia textbooks have a promising future in radiology education.

An approach to the creation of multimedia textbooks for radiology instruction.

We developed a standardized approach for creating computerized multimedia textbooks based on four principles: (1) multimedia textbooks should resemble printed books, (2) the creation of multimedia textbooks should be relatively inexpensive, (3) multimedia textbooks should be completely digital, and (4) the construction of multimedia textbooks should be simple. To facilitate this approach, an inexpensive, user-friendly multimedia authoring tool called The Annotator was used. The Annotator, a Hypercard-based program that runs on any Macintosh computer, helps authors rapidly create sophisticated radiologic multimedia textbooks. This program provides a textbooklike shell that can be filled with digitized media (video clips, audio clips, images, and text). This approach, which is applicable to any multimedia hardware platform, allows the authorship of multimedia textbooks that can be easily transported to any future multimedia platform.
