Supplementary file 4_Comparison of the teaching effect of problem-based learning and case-

Qun Li authored a study comparing the teaching effects of problem-based learning (PBL) and case-based learning (CBL) in dental endodontics education. The research involved 156 junior undergraduate dental students at the School of Stomatology, Hunan University of Chinese Medicine, who were evaluated on theoretical knowledge, practical skills, and learning attitudes after a semester-long teaching intervention. The dataset was last updated on May 12, 2026.

Use Cases

• Compare the effectiveness of different pedagogical methods based on student performance metrics described in the study.
• Analyze the relationship between teaching style and specific learning outcomes like practical skill proficiency or theoretical knowledge integration.
• Investigate student satisfaction and learning attitudes in response to problem-based versus case-based instructional models.

Strengths

• The study design includes a specific sample size of 156 students divided into two equal groups.
• Evaluation is based on multiple concrete metrics: theoretical knowledge tests, practical skill assessments, self-learning ability, and satisfaction surveys.
• The dataset has a clear, permissive license (CC-BY-4.0) for reuse.

Limitations

• The dataset is very small (15.0 KB), suggesting limited scope or summary-level data rather than raw student-level records.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for detailed statistical analysis.
