Development and evaluation of a PICC virtual simulator in neonatal nursing: A randomized controlled trial

BackgroundPeripherally Inserted Central Catheter (PICC) is essential in neonatal care, especially for critically ill infants. Traditional training for neonatal PICC insertion faces challenges such as high costs and limited practice opportunities. Virtual simulation technology has emerged as a potential training tool, providing a realistic, risk-free learning environment. ObjectivesThe study aimed to assess the effectiveness of a virtual simulation teaching system in neonatal PICC care training, focusing on improving nursing students' knowledge， skills and interest in pediatric nursing. DesignA quasi-experimental design was used, with assessments conducted before and after the activity. ParticipantsThe study involved 58 graduate nursing students from China Medical University, divided into experimental and control groups. MethodsThe System Usability Scale (SUS) was utilized to assess teachers' experiences with the PICC virtual simulation software. Students' perceptions of the software and their interest in pediatric nursing were measured using Self-Administered Questionnaires. Furthermore, Theoretical and Operational Assessments were applied to determine the extent of students' knowledge and practical skills before and after experimentation. ResultsTeachers and students have favorably evaluated the software system, with notable improvements in theoretical scores following testing. While the virtual simulation system does not enhance practical skills, it does increase student interest in pediatric nursing and employment. ConclusionsThis neonatal virtual simulation software serves as a complement to, rather than a replacement for, traditional clinical training. Its integration into educational programs significantly enhances learning outcomes.

Chemical simulation teaching system based on virtual reality and gesture interaction

BackgroundMost existing chemical experiment teaching systems lack solid immersive experiences, making it difficult to engage students. To address these challenges, we propose a chemical simulation teaching system based on virtual reality and gesture interaction. MethodsThe parameters of the models were obtained through actual investigation, whereby Blender and 3DS MAX were used to model and import these parameters into a physics engine. By establishing an interface for the physics engine, gesture interaction hardware, and virtual reality (VR) helmet, a highly realistic chemical experiment environment was created. Using code script logic, particle systems, as well as other systems, chemical phenomena were simulated. Furthermore, we created an online teaching platform using streaming media and databases to address the problems of distance teaching. ResultsThe proposed system was evaluated against two mainstream products in the market. In the experiments, the proposed system outperformed the other products in terms of fidelity and practicality. ConclusionsThe proposed system which offers realistic simulations and practicability, can help improve the high school chemistry experimental education.

Design of intelligent simulation teaching system for college professional courses based on virtual scene

Abstract With the continuous development and progress of network science and technology, virtual reality technology has been accelerated into the field of education. Intelligent Q&A is integrated with virtual technology to create a virtual classroom in this paper. In the process of constructing the virtual classroom, the most crucial terrain modeling is completed using image drawing technology, and the general framework of the virtual classroom is obtained. BERT matches the possible statements in the Q&A system, starting with text recognition. The hypotheses related to the virtual scene are proposed. The validity of the hypotheses is verified, and the effect of using the teaching system is analyzed from three aspects, namely, learning satisfaction, professional course grades, and lecture effect. The results showed that the perceived usefulness of the teaching system had the most significant impact on student’s attitudes toward its use, with a regression coefficient of 0.6452 and a p-value of less than 0.01, and the hypotheses were all valid. The head-up rates of students in the two majors were 56.4061% and 70.2056%, respectively, which ranged from 50% to 75%. The evaluation grade was “good,” and the overall performance of the simulation teaching system was good.

Design and Application of Virtual Simulation Teaching System under Artificial Intelligence Orientation

Abstract This paper builds a virtual simulation teaching system based on the Unity simulation platform, which contains a network connection module, resource loading module, and so on. Using the combination of natural interaction and virtual simulation teaching system, the design of Kinect depth information and SVM classifier for gesture recognition classification is integrated with the virtual simulation teaching scene to realize cross-platform collaborative interaction. The virtual simulation teaching process involves a large number of gesture interaction processes, using mf-score multi-feature selection of features that play a vital role in the classification of the data set, eliminating the raw noise of the customized gesture data and improving the contrast of the gesture image. The results of the practical application of the virtual simulation teaching system show that the discipline to which the virtual simulation course belongs (0.008) and the time of identification (0.047) have a significant effect on its application activity. The multisensory, immersive, and interactive nature of virtual simulation teaching (P < 0.001) all have a highly significant positive effect on learners’ foreign language useability. The foreign language assessment score at the end of the virtual simulation course is (92.74±3.32), which is significantly different from the traditional teaching method (P<0.01). The teaching system in this paper meets the requirements of most learners in terms of interactive interface, function, and content.
