Construction of learner profile models for clinical medical courses
从学习背景、兴趣偏好和行为效果3个维度构建临床医学专业课程学习者画像模型。学习背景画像揭示了学习者基本信息、认知基础和学习动机。兴趣偏好画像分析了学习目的与其他选课信息,根据内容关注程度、学习效果影响因素识别出3类不同的学习者群体。行为效果画像通过构建4种机器学习算法预测模型实现了对课程考试成绩的分类预测,结果显示朴素贝叶斯算法效果最佳,准确率为0.80、F1分数为0.79,受试者工作特征(receiver operating characteristic,ROC)曲线下面积(area under the curve,AUC)为0.79(
To construct a learner profile model for clinical medical courses with the course "Application of ultrasound in anesthesia
pain and critical care medicine"
as an example.
Methods
2
The framework and procedures were established for constructing the learner profile model for clinical medicine courses
and learner data from multiple sources were collected and pretreated. Python 3.9 programming language was used to perform statistical analysis
natural language processing
and cluster analysis
and the results were presented using visualization techniques. Machine learning prediction models were established and evaluated in terms of prediction performance.
Results
2
The learner profile model for clinical medical courses was established from the three dimensions of learning background
learning interests and preferences
and learning behaviors and effects. The learning background profile revealed the basic information
cognitive foundation
and learning motivation of learning. The interests and preferences profile analyzed the learning objectives and other selective courses of learners
and three different groups of learners were identified based on content attention and influencing factors for learning effects. The behaviors and effects profile achieved the classified prediction of course examination scores by constructing four machine learning algorithms
and the results showed that the naive Bayes algorithm had the best effect
with an accuracy of 0.81
an F1 score of 0.79
an area under the receiver operating characteristic curve of 0.79
and a
P
value of 0.035
indicating significant differences between the naive Bayes algorithm and other algorithms.
Conclusion
2
This study constructs a learner profile model for clinical medical courses and conducted an empirical study
and the results of this model provides guidance and suggestions for teaching contents
