摘要

目的

评估智慧化多模态知识图谱在《营养与食品卫生学》课程中的应用效果，分析学生学习中的实际困难、需求与优化建议。

方法

在定量问卷调查中，以35名预防医学专业大四学生为研究对象，围绕课前预习、课上学习、课后复习3个核心环节，通过量化数据客观呈现知识图谱的使用现状及效果评价。定性研究采用专题小组讨论法与半结构式深度访谈法，深入分析其使用体验、现存问题及需求。

结果

多模态知识图谱在搭建知识框架、提升预习效率、辅助知识点梳理方面具有一定应用价值，94.29%的学生（33人）在课前使用了该工具，77.14%的学生（27人）认为其对把握重难点有一定帮助，但存在界面不友好（17人，48.57%）、操作不便（15人，42.86%）、内容缺乏针对性（17人，48.57%）、线上线下兼容性有待改善等问题，学生自主使用意愿有待提升，整体满意度为71.43%（25人），51.43%的学生（18人）明确愿意在后续课程中继续使用。

结论

智慧化多模态知识图谱有助于学生搭建知识框架和提升预习效率，但需要进一步与线下课程教学相融合，提升操作便捷性和流畅性，及时更新和优化课程内容。

Abstract

Objective

To evaluate the effectiveness of intelligent multimodal knowledge graph in the course of

Nutrition and Food Hygiene

analyze the practical difficulties

needs

and optimization suggestions for students in learning.

Methods

In the quantitative questionnaire survey

35 senior undergraduate students majoring in preventive medicine were selected as the research subjects. Focusing on the three core stages of pre-class preparation

in-class learning

and post-class review

the current status and effectiveness evaluation of knowledge graph usage were objectively presented through quantitative data. The qualitative research adopted the focus group discussion and semi-structured in-depth interview to deeply analyze the user experience

existing problems

and needs.

Results

The multimodal knowledge graph had certain application value in building knowledge frameworks

improving preview efficiency

and assisting in the organization of knowledge points. Moreover

94.29%(

=33) of the students used this tool before class

and 77.14%(

=27) of the students believed it was helpful in identifying key and difficult points. However

there were issues that needed to be improved

such as an unfriendly interface (

=17

48.57%)

inconvenient operation (

=15

42.86%)

lack of targeted content (

=17

48.57%)

and inadequate compatibility between online and offline platforms. The willingness of students to use the tool needs to be enhanced. The overall satisfaction rate was 71.43%(

=25)

and 51.43%(

=18) explicitly expressed willingness to continue using it in subsequent courses.

Conclusions

Intelligent multimodal knowledge graph facilitate knowledge framework construction and preview efficiency for students. To maximize effectiveness

they should be further integrated with offline teaching

with improved ease of use and fluency

and timely content updates and optimization.
