To address the challenges in traditional chemical fiber production training—such as high costs

high risks

insufficient depth

and limited innovation cultivation—this study takes the “Chemical Fiber Production Training” course for Polymer Materials and Engineering at Henan University of Engineering as a case study to construct and implement a “virtual-real integration

virtual-assisted real” virtual simulation teaching system. Guided by course objectives

the system features a high-fidelity virtual simulation platform covering three levels (“cognition-operation-evaluation”) and seven core modules. It accurately replicates the core processes and equipment structures of melt and wet spinning. The pedagogical approach employs a three-step model: “pre-class virtual preview

in-class virtual-real comparison

and post-class virtual expansion”

which deeply integrates virtual simulation into the entire teaching process. Quantitative evaluation of teaching effectiveness and analysis of course objective attainment showed that the new model significantly enhanced students’ engineering design and innovative practice capabilities (mean achievement of course objectives>0.81). It is particularly effective in cultivating higher-order skills

such as solving complex engineering problems and data analysis. This study confirms that the “objective-oriented

virtual-real fusion

closed-loop evaluation” teaching system represents a systematic reconstruction of traditional engineering practice paradigms. It provides a replicable and scalable solution for addressing common practical teaching challenges in similar fields.
