Analysis of Factors Influencing Experimental Teaching Satisfaction Based on ISM-MICMAC

The satisfaction with experimental teaching is of utmost importance for improving educational quality, promoting student development, and fostering the professional growth of teachers. Researching the factors influencing satisfaction with experimental teaching, as well as the hierarchical relationships and mechanisms of action among these factors, provides significant theoretical foundations and practical guidance for conducting scientific and targeted reforms in experimental teaching. Based on literature research and questionnaire surveys, fifteen factors affecting experimental teaching satisfaction were selected across five dimensions: teachers, curriculum, students, environment, and interaction. The Interpretive Structural Modeling (ISM) was used to reveal the hierarchical relationships among these factors, and the Cross-Impact Matrix Multiplication Applied to a Classification (MICMAC) method was employed to validate the model’s scientific validity and assess the driving forces and dependencies of each factor. The research results indicate that self-efficacy, academic emotions, perceived course value, teacher-student interaction, and peer interaction are direct factors influencing experimental teaching satisfaction and exhibit a high level of interdependence. Teacher’s teaching competence, laboratory management, course content, course resources, and laboratory environment are deeper influencing factors with strong driving forces, positively impacting both the direct factors and intermediary factors such as teaching models and course assessment. Based on the analysis results, improvement strategies, and recommendations are proposed to enhance the quality of experimental teaching and the effectiveness of talent development.

Design of an Optical Physics Virtual Simulation System Based on Unreal Engine 5

In response to challenges in traditional offline experiments in optical physics, such as high trial-and-error costs, expensive equipment, limited design parameters, and restricted explanations of instrument structures and principles, this paper proposes a design method for an optical physics virtual simulation system based on Unreal Engine 5. The method employs a generic design architecture to partition system units and utilizes technologies like pixel streaming, rendering engines, and physics engines to implement the design of the virtual simulation system. This system covers the entire experimental process, including video learning, instrument adjustment, phenomenon observation, data measurement and recording, and grade inquiry. The proposed design method enhances the immersive experience of experiments, reduces the hardware performance requirements for users, and allows access and utilization across multiple platforms. It efficiently facilitates physics teaching through simulated experiments, thereby effectively improving the quality of experimental teaching. Finally, through a comparison with existing virtual simulation systems, it is demonstrated that the system can save approximately 94.76% of the average CPU usage and provide better immersion and user experience advantages.

Application of ICP-MS in the Innovation and Practice of Instrument Analysis Course - Taking the Determination of Cesium in Soil as an Example

Instrumental analysis is an important part of analytical chemistry, which plays a crucial role in cultivating the experimental operation ability of students in disciplines such as environment, geology, and medicine.

Comprehensive Evaluation of Experimental Teaching Quality Using AHP-TOPSIS Technique

The key of university experimental teaching is to help students gradually perfect from knowledge learning to improvement of actual operational ability through experiments in the teaching and learning process. University experimental teaching is conducive for promoting innovative thinking and ability of practice of university students, and it plays an important role in the entire talent training system. Establishing scientific and reasonable evaluation methods and reflecting shortages in practical experimental teaching are not only keys of evaluation but also important guarantee to improve university experimental teaching quality. In this study, an evaluation index system of experimental teaching quality was constructed by combining analytic hierarchy process (AHP) and technique for order preference by similarity to ideal solution (TOPSIS). Weights of indexes were determined. Moreover, a case study based on a comprehensive evaluation of experimental teaching quality of Construction Engineering CAD for civil engineering majors of undergraduates was performed. Results demonstrated that Level 2 indexes about teachers’ good preparation of lessons and complete and standard teaching documents (X-1-3), as well as students’ active thinking and positive participation in classroom learning (X-3-2), had the highest weight. Students’ evaluation ranking results provided quantitative references to more scientific evaluation of experimental teaching. The comprehensive evaluation of experimental teaching quality using AHP-TOPSIS technique solves the mutual dependence and feedback relationship among evaluation indexes effectively, and avoids influences of subjectivity and one-sidedness of artificial weighting. Research conclusions can provide important references to optimize experimental teaching process, train the innovation ability of students, increase the comprehensive quality of students, and deepen reform in experimental teaching.
