The use of cognitive task analysis to improve the learning of percutaneous tracheostomy placement.

OBJECTIVE: The purpose of the current study was to determine the effectiveness of using cognitive task analysis (CTA) to develop a curriculum to teach the behavioral skills and the cognitive strategies of a percutaneous tracheostomy (PT) placement. METHODS: Postgraduate 2, 3, and 4 general surgery residents were randomly assigned to either the CTA group (N = 9) or the control group (N = 11). The CTA group was taught percutaneous tracheostomy placement using the CTA curriculum. The control group received the traditional curriculum. RESULTS: The CTA group performed significantly higher on the PT procedure at 1 month (CTA: 43.5 +/- 3.7, control 35.2 +/- 3.9, P = .001) and at 6 months post-instruction (CTA: 39.4 +/- 4.2, control: 31.8 +/- 5.8, P = .004). In addition, the CTA group demonstrated superior cognitive strategies than the control group (CTA: 25.4 +/- 5.3, control: 19.2 +/- 2.0, P = .004). CONCLUSIONS: The use of CTA was effective in improving the cognitive processes and technical skills of performing a PT for surgical residents.

Guidelines for cognitively efficient multimedia learning tools: educational strategies, cognitive load, and interface design.

The field of medical education has consistently embraced new technologies in an attempt to improve the training process of our nation's doctors. There are thousands of available multimedia learning tools (MMLTs), but no quantitative scale exists to assess their efficiency and overall educational value. The authors review existing literature and suggest guidelines for creating cognitively efficient medical MMLTs. In 2004, the authors searched PubMed to identify articles regarding mutimedia learning, including educational strategies and existing MMLTs. The primary search terms included "multimedia learning," "cognitive load," and "surgical education." The resulting articles were evaluated and reviewed for educational and interface design techniques, and a list of common features was generated. The authors cross-referenced these features with extensive theories of cognitive load to create a list of methods that demonstrated improved learning. Techniques common to existing MMLTs often neglect to account for theories of cognitive load and may be detrimental to the learning process. The authors outlined important educational considerations and guidelines for the design of effective MMLTs. With large resources being spent to produce MMLTs, more research is necessary to establish successful design techniques. The authors summarized existing research, outlined educational issues in multimedia design, and proposed future directions for study.

Surgical Multimedia Academic, Research and Training (S.M.A.R.T.) tool: a comparative analysis of cognitive efficiency for two multimedia learning interfaces that teach the pre-procedural processes for carpal tunnel release.

This study proposes a series of guidelines for designing multimedia educational interfaces that combine educational strategies with cognitive load theory. There is a large body of research that confirms multimedia education is at least as effective as the traditional approach, but there is no discussion regarding the effectiveness of the interface design. This trial compares two interfaces to determine which design techniques are most cognitively efficient for the learner.

Advanced technologies in plastic surgery: how new innovations can improve our training and practice.

Over the last two decades, virtual reality, haptics, simulators, robotics, and other "advanced technologies" have emerged as important innovations in medical learning and practice. Reports on simulator applications in medicine now appear regularly in the medical, computer science, engineering, and popular literature. The goal of this article is to review the emerging intersection between advanced technologies and surgery and how new technology is being utilized in several surgical fields, particularly plastic surgery. The authors also discuss how plastic and reconstructive surgeons can benefit by working to further the development of multimedia and simulated environment technologies in surgical practice and training.
