OBJECTIVE Simulation is gaining momentum as a new modality of medical training, particularly in acute care settings such as surgery. In the present study, the authors aimed to compare individual cognitive skills with manual abilities as assessed by virtual reality (VR) simulation among neurosurgical residents. METHODS Participants were asked to complete a multiple-choice questionnaire assessing their surgical abilities regarding three basic neurosurgical procedures (endoscopic third ventriculostomy, cranial meningioma, and lumbar laminectomy). They subsequently performed these same three procedures on a VR simulator (NeuroTouch). RESULTS The authors found that cognitive scores correlated with self-evaluation of surgical experience and autonomy. On the contrary, VR simulation, as assessed by NeuroTouch automated scoring, did not reflect participants’ cognitive or self-evaluation of their surgical proficiency. CONCLUSIONS The results of this study suggest that neurosurgical education should focus as much on cognitive simulation (e.g., careful planning and critical appraisal of actual procedures) as on VR training of visuomotor skills.

We conducted a comprehensive meta-analysis for evaluating the effectiveness of Virtual Reality (VR) on the rehabilitation and training of individuals diagnosed with an autism spectrum disorder. After a systematic search and targeted screening, 33 articles were analyzed. Results revealed that individuals undergoing VR training have remarkable improvements with a large effect size (g= 0.76). Furthermore, the results of the analysis of different skills indicated diverse effectiveness. The strongest effect was observed for daily living skills (g=1.23). This effect was moderate for other skills: g=0.45 for Cognitive skills, g=0.47 for Emotion Recognition skills, and g=0.67 for Social and Communication skills. In conclusion, the application of VR-based settings in clinical practice is highly encouraged, though their standardization and customization need more research.

While research on Irish-medium immersion education (IME) has heralded benefits such as cognitive skills, academic achievement and language and literacy development, many studies have also identified challenges to its successful implementation. Immersion-specific research-validated tools can help school leaders navigate the school self-evaluation journey, critically review and evaluate the quality of aspects of their school’s provision and plan for improvement. This paper reports on one theme, leadership, from a larger study, Quality indicators of best practice in Irish-medium immersion (Ó Ceallaigh and Ní Shéaghdha, 2017). Qualitative in nature, the study was guided by the following research question: What are IME educators’ perceptions of best practices in IME?. The study explored 120 IME educators’ perceptions of best practice in IME to inform the development of IME quality indicators. Individual interviews and focus group interviews were utilised to collect data. Data analysis revealed particular themes related to best IME leadership practices. Findings in turn informed the design of an evidence-informed school self-evaluation tool for IME settings. The various functions of the tool will be explored with a particular emphasis on building teaching and leadership capacity in IME through the school self-evaluation process.

Algorithmic Bias

Virtual reality (VR) is an emerging technology with the potential to extract significantly more data about learners and the learning process. In this article, we present an analysis of how VR education technology companies frame, use and analyse this data. We found both an expansion and acceleration of what data are being collected about learners and how these data are being mobilised in potentially discriminatory and problematic ways. Beyond providing evidence for how VR represents an intensification of the datafication of education, we discuss three interrelated critical issues that are specific to VR: the fantasy that VR data is ‘perfect’, the datafication of soft-skills training, and the commercialisation and commodification of VR data. In the context of the issues identified, we caution the unregulated and uncritical application of learning analytics to the data that are collected from VR training.

Objective Otologic diseases are common in all age groups and can significantly impair the function of this important sensory organ. To make a correct diagnosis, the correct handling of the otoscope and a correctly performed examination are essential. A virtual reality simulator could make it easier to teach this difficult-to-teach skill. The aim of this study was to assess the face, content, and construct validity of the novel virtual reality otoscopy simulator and the applicability to otologic training. Study Design Face and content validity was assessed with a questionnaire. Construct validity was assessed in a prospectively designed controlled trial. Setting Training for medical students at a tertiary referral center. Method The questionnaire used a 6-point Likert scale. The otoscopy was rated with a modified Objective Structured Assessment of Technical Skills. Time to complete the task and the percentage of the assessed eardrum surface were recorded. Results The realism of the simulator and the applicability to medical training were assessed across several items. The ratings suggested good face and content validity as well as usefulness and functionality of the simulator. The otolaryngologists significantly outperformed the student group in all categories measured (P < .0001), suggesting construct validity of the simulator. Conclusion In this study, we could demonstrate face, content, and construct validity for a novel high-fidelity virtual reality otoscopy simulator. The results encourage the use of the otoscopy simulator as a complementary tool to traditional teaching methods in a curriculum for medical students.

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.

Object Complications of specific pediatric neurosurgical procedures are well recognized. However, focused surveillance on a specific neurosurgical unit, for all procedures, may lead to better understanding of the most important complications, and allow targeted strategies for quality improvement. Methods The authors prospectively recorded the morbidity and mortality events at a large pediatric neurosurgical unit over a 2-year period. Morbidity was defined as any significant adverse outcome or death (for obstructive shunt failure, within 30 days). Multiple and unrelated complications in the same patient were recorded as separate events. Results There were 1082 surgical procedures performed during the evaluation period. One hundred seventy-seven complications (16.4%) occurred in 147 patients. By procedure, the most common complications occurred in vascular surgery (41.7%) and brain tumor surgery (27.9%). The most common complications were CSF leakage (31 cases), a new neurological deficit (27 cases), early shunt or endoscopic third ventriculostomy obstruction (27 cases), and shunt infection (24 cases). Meningitis occurred in 19 cases: in 58% of shunt infections, 13% of CSF leaks, and 10% of wound infections. Sixty-four percent of adverse events required a second procedure, most commonly an external ventricular drain placement or shunt revision. Conclusions Complications in pediatric neurosurgical procedures are common, result in significant morbidity, and more than half the time require a repeat surgical procedure. Targeted strategies to prevent common complications, such as shunt infections or CSF leaks, might significantly reduce this burden.
