七、展望
Future Work
中外联合办学是高等教育国际化的关键途径之一。通过引入国外优质教育资源，旨在提升我国高等教育机构的教育质量和水平，加速其国际化进程。在《电工与电子技术》课程的教学实践中，充分发挥西里西亚智能科学与工程学院的办学优势，有效融合中外优质教育教学资源，优化专业课程架构，进一步提升教育教学质量和人才培养层次。为学院开展高质量教育教学改革及培养高素质专业人才提供了坚实的理论和实践支撑。
Sino-foreign joint school running is one of the keys to higher education internationalization. By introducing high-quality educational resources from abroad, Chinese higher education institutions aim to enhance the quality and level of higher education and accelerate their internationalization process. In the teaching practice of the course "Electrotechnics and Electronics Technology", Silesian College of Intelligent Science and Engineering at Yanshan University effectively integrate high-quality educational and teaching resources at home and abroad, optimize the professional course structure, and further enhance the quality of education and teaching as well as the level of talent cultivation. It has provided solid theoretical and practical support for the College’s initiatives of high-quality educational reform and high-caliber professional talents cultivation.
此外，中波两国的老师还考虑提议开发一种创新的双语（英汉）出版物，以帮助学生掌握电气和电子工程的基础知识，并提高他们的语言能力。这样的教材不仅会成为一种有效的教学工具，还将促进跨文化交流，并代表技术教育进一步国际化的重大进展。
Moreover, the Chinese and Polish faculty members have proposed the development of an innovative bilingual (English–Chinese) publication that will support students in both mastering the fundamentals of electrical and electronic engineering and in strengthening their language competence. Such a work will not only provide an effective teaching tool, but will also foster intercultural collaboration and represent a significant step towards the further internationalization of technical education.
