Construction of the Integrated Curriculum System of Interior Design 1+X and "Job-Course-Certificate"

The existing teaching methods of interior design have problems such as disconnection between theory and practice, insufficient professional skills training, weak students' practical ability, and low employment competitiveness, which make it difficult to address the industry's requirement for high-quality skilled individuals. To this end, this paper constructs a curriculum system integrating Interior Design 1+X and "Job Course Certificate" to optimize the curriculum structure, raise the standard of hands-on instruction and develop students' professional skills. The curriculum system adjusts the ratio of compulsory and elective courses and strengthens the skill training module, so that students can systematically master core skills such as survey and measurement, scheme design, construction drawing, material and budget management. At the same time, the "project-driven + case teaching" model is adopted to apply emerging tools such as VR/AR technology, BIM modeling, and smart home design to improve students' ability to apply digital technology. The course also combines 1+X certificate training to enable students to successfully pass the professional skill level examination, and integrates skill competition training to cultivate innovation and teamwork capabilities. Experimental data show that in terms of theoretical examinations, the average score of the experimental group in the pre-test is 68.5 points, and the average score of the control group is 69.2 points, with similar initial levels. However, after the course system is optimized, the average score of the experimental group in the post-test increased to 82.3 points, an increase of 13.8 points compared to the pre-test, while the control group only increased by 3.6 points (the average score of the post-test is 72.8 points). This result shows that the optimization of the integrated course system in the construction of the knowledge system, the application of case teaching, and the combination of theory and practice has improved students' theoretical understanding ability.
