研究目的
To improve the teaching of near-infrared spectroscopic analysis for undergraduates through elective open experiment courses, discipline competitions, and graduation theses.
研究成果
The approaches of using elective open experiment courses, discipline competitions, and graduation theses are effective in teaching near-infrared spectroscopy to undergraduates. These methods enhance students' theoretical knowledge, practical skills, and innovation abilities, preparing them for industrial applications.
研究不足
The multiplicity of disciplines involved in NIR spectroscopy poses a challenge for students and teachers. Students' limited knowledge in mathematics and computer science affects their understanding of calibration modeling. The accuracy of chemical measurements by lower-grade students can be inconsistent.
1：Experimental Design and Method Selection:
The study explores teaching methods for near-infrared spectroscopy, including elective lab courses, innovation competitions, and graduation theses.
2：Sample Selection and Data Sources:
Students engage in projects like the determination of silk content in textiles and the identification of silkworm pupae gender.
3：List of Experimental Equipment and Materials:
Includes NIR spectrometers (USB4000, NIRQuest 512, Maya2000 Pro, MicroNIR 1700, NIRscan Nano EVN), light sources, optical fibers, and detection cells.
4：Experimental Procedures and Operational Workflow:
Students perform experiments, develop calibration models, and use handheld NIR spectrometers for real-time analysis.
5：Data Analysis Methods:
Utilizes partial least squares discriminant analysis and other statistical methods for data interpretation.
