In interventional radiology, physicians require high haptic sensitivity and fine motor skills development because of the limited real-time visual feedback of the surgical site. The transfer of this type of surgical skill to novices is a challenging issue. This paper presents a study on the design of a biopsy procedure learning system. Our methodology, based on a task-centered design approach, aims to bring out new design rules for virtual learning environments. A new collaborative haptic training paradigm is introduced to support human-haptic interaction in a virtual environment. The interaction paradigm supports haptic communication between two distant users to teach a surgical skill. In order to evaluate this paradigm, a user experiment was conducted. Sixty volunteer medical students participated in the study to assess the influence of the teaching method on their performance in a biopsy procedure task. The results show that to transfer the skills, the combination of haptic communication with verbal and visual communications improves the novices’ performance compared to conventional teaching methods. Furthermore, the results show that, depending on the teaching method, participants developed different needle insertion profiles. We conclude that our interaction paradigm facilitates expert-novice haptic communication and improves skills transfer; and new skills acquisition depends on the availability of different communication channels between experts and novices. Our findings indicate that the traditional fellowship methods in surgery should evolve to an off-patient collaborative environment that will continue to support visual and verbal communication, but also haptic communication, in order to achieve a better and more complete skills training.

In the field of technology education, virtual reality (VR) training has received significant attention in terms of its efficacy in use. Given its many advantages, there is a specific need to emphasize concrete measures for the implementation of VR training in the field of tech education. VR training based on mobile environments has been touted as a means of not only enhancing presence, flow, and learning authenticity, but also of minimizing spatial and temporal constraints. The present study has developed an evaluation tool for VR training contents, including those based on mobile environments. After categorizing VR training contents in the field of tech education into structure comprehension type, procedure learning type, and equipment experiment type contents, we constructed items for each evaluation area. The considered areas included learning, media, and content quality. By conducting Delphi surveys with a panel of experts, we confirmed that the derived evaluation items differed in number across different types of content. Under the learning area, satisfaction was found to be adequate for all content types. Items such as flow, interactivity, and learning effects were found to be adequate for procedure learning and equipment experiment type contents. The media area indicated marked variability in item adequacy depending on the content type. Usability was found to be adequate only for procedure learning type content. For equipment experiment type content, items such as presence, usability, and manipulability were all found to be adequate. All evaluation items under the content design area were found to be adequate across all content types. Thus, regardless of the type of content, it is necessary to fulfil the basic elements within the content design area in order to establish the efficacy of VR training as educational content in the field of tech education.

Abstract Working in a large oncology hospital, central venous catheters are indispensable devices in which to deliver chemotherapy regimens and other supportive care medication administration. The necessity for a central venous catheter (CVC) initiates a patient education process that requires informing, educating and preparing the patient for the insertion and post-management requirements. It is crucial to organize and plan the strategies necessary to meet the needs of patients in a timely manner, decrease cost, and improve patient outcomes. By interviewing patients prior to a CVC placement, patients can be better prepared for the procedure, learning needs can be identified and patient education can begin. Patients and family members view the “Informed Consent” video, which explains the insertion procedure, risk, benefits, alternatives, possible complications and catheter care requirements. This article will focus on how the need for the interview process was identified and implemented and the format for an interview.

Research has shown that nonexamples are an effective strategy in teaching concepts. The purpose of this study was to explore the use of common errors (CE) as an effective strategy in teaching a procedure (i.e., a set of steps that one follows to achieve a goal). A total of fifty-six sophomore students were randomly assigned to an experimental and a control condition in their regular classrooms. The experimental design was pretest-posttest. Materials and task involved two sets of identical slide projectors and tape recorders to teach the procedure for color correction of color transparencies. The experimental group received instruction on an extra sample of colors most commonly confused with each of the six colors of the standard color wheel. Results indicated that application-level learning of procedures was significantly facilitated by the presentation of common errors (CE) in addition to examples. In conclusion the use of common errors of great divergence is beneficial. The use of common errors is more effective when they are made apparent, or when a clear distinction between a correct and incorrect response is taught.
