Research on online and offline integrated teaching mode of labor education practice for nursing students by integrating mixed reality technology

Abstract

The traditional teaching mode focuses on the explanation of the theoretical knowledge of labor education, but the medical case knowledge is relatively specialized, while some of the knowledge is highly abstract, the students' practical understanding is low, and the teaching progress is slow. In this regard, the study firstly designed an online and offline integrated labor education curriculum system based on mixed reality technology (MR), and proposed practical teaching in labor education based on virtual classroom and three-dimensional images. Then, the 3D image reconstruction is designed using this technology, and the image schematic is formed using the coordinate system calculation and 3D reconstruction principle. The feature point matching accuracy of MR-based 3D reconstruction technology reaches 86.5%, and the camera trajectory error is small, which ensures the quality of image reconstruction results. Finally, in this paper, 80 students undergoing internship in the Second Affiliated Hospital of Medical University of Province A were selected as the observation objects, and the satisfaction of teaching mode, assessment results and labor literacy of the two groups of students were compared and analyzed. The results show that the teaching mode of labor education for nursing majors based on MR technology can effectively improve teaching efficiency, enhance students' satisfaction, and facilitate the growth of students' assessment scores.
