“…Different types of penalty factors have also been used previously, such as fixed factor for all error types (Berg et al, 2015;D. R. Cox, Zeng, Frisella, & Brunt, 2011;Matzke et al, 2017) or different factors depending on the type of error (M. L. Cox et al, 2020). We used the same general formula to calculate the score, which we also used as our primary outcome measure.…”

“…Scoring metrics for laparoscopic training tasks vary depending upon the trainer used for practice and the modality of importance (i.e., task completion time, errors, or the combination of both). Usually, task completion time is used as a score after penalizing it for the errors (i.e., Score = Cut-off time – (Task completion time + (penalty * factor)) (Berg et al, 2015; Derossis et al, 1998; Matzke, Ziegler, Martin, Crawford, & Sutton, 2017). Cut-off time is pre-selected and is often 300 s in peg-transfer task, which is an approximate measure of task completion time used in Fundamentals of Laparoscopic Surgery (Derossis et al, 1998).…”

Introduction: Efficient training methods are required for laparoscopic surgical skills training to reduce the time needed for proficiency. Transcranial direct current stimulation (tDCS) is widely used to enhance motor skill acquisition and can be used to supplement the training of laparoscopic surgical skill acquisition. The aim of this study was to investigate the effect of anodal tDCS over the primary motor cortex (M1) on the performance of a unimanual variant of the laparoscopic peg-transfer task. Methods: Fifteen healthy subjects participated in this randomized, double-blinded crossover study involving an anodal tDCS and a sham tDCS intervention separated by 48 hours. On each intervention day, subjects performed a unimanual variant of laparoscopic peg-transfer task in three sessions (baseline, tDCS, post-tDCS). The tDCS session consisted of 10 minutes of offline tDCS followed by 10 minutes of online tDCS. The scores based on the task completion time and the number of errors in each session were used as a primary outcome measure. A linear mixed-effects model was used for the analysis. Results: We found that the scores increased over sessions (p<0.001). However, we found no effects of stimulation (anodal tDCS vs. sham tDCS) and no interaction of stimulation and sessions. Conclusion: This study suggests that irrespective of the type of current stimulation (anodal and sham) over M1, there was an improvement in the performance of the unimanual peg-transfer task, implying that there was motor learning over time. The results would be useful in designing efficient training paradigms and further investigating the effects of tDCS on laparoscopic peg-transfer tasks.

The popularity of virtual reality headsets have been rapidly increasing. With this technology, students can efficiently interact with the course content and learn the material faster than the traditional methodologies. In addition to this benefit, virtual reality devices also draw the attention of young generation and this helps to the widespread use of this technology among students. In this study, we investigate the use of virtual reality on the performance of computer engineering bachelor science (BS) students within the scope of Data Structures course and develop a software‐intensive system called “Virtual Reality Enhanced Interactive Teaching Environment” (VR‐ENITE). Specifically, we focus on the sorting algorithms such as selection sort, bubble sort, insertions sort, and merge sort which are relatively hard to be understood by the BS students at first glance. For the evaluation of VR‐ENITE, students were divided into two groups: a group which uses VR‐ENITE in addition to the traditional teaching material and the control group which utilizes from only the traditional material. In order to evaluate the performance of these two groups having 36 students in total, a multiple choice exam was delivered to all of them. According to the test results, students who used the VR‐ENITE system got 12% more successful results in average than the students who are in the control group. This study experimentally shows that VR‐ENITE which is based on virtual reality technology is effective for teaching software engineering courses and it has assistive capabilities for traditional teaching approaches.

“…Diante dos resultados atuais e da revisão da literatura, é possível sugerir que o treinamento com SRV ou com CP seja capaz de reduzir o tempo cirúrgico e promover melhor desempenho cirúrgico. Porém, ainda não se pode afirmar que o treinamento com simuladores seja capaz de melhorar os desfechos cirúrgicos dos pacientes operados por médicos treinados (Nagendran et al, 2013;Gurusamy et al, 2014;Matzke et al, 2017).…”
