Purpose Manual grading is time-consuming and prone to inconsistencies, prompting the exploration of generative artificial intelligence tools such as GPT-4 to enhance efficiency and reliability. This study investigated GPT-4’s potential in grading pharmacy students’ exam responses, focusing on the impact of optimized prompts. Specifically, it evaluated the alignment between GPT-4 and human raters, assessed GPT-4’s consistency over time, and determined its error rates in grading pharmacy students’ exam responses.
Methods We conducted a comparative study using past exam responses graded by university-trained raters and by GPT-4. Responses were randomized before evaluation by GPT-4, accessed via a Plus account between April and September 2024. Prompt optimization was performed on 16 responses, followed by evaluation of 3 prompt delivery methods. We then applied the optimized approach across 4 item types. Intraclass correlation coefficients and error analyses were used to assess consistency and agreement between GPT-4 and human ratings.
Results GPT-4’s ratings aligned reasonably well with human raters, demonstrating moderate to excellent reliability (intraclass correlation coefficient=0.617–0.933), depending on item type and the optimized prompt. When stratified by grade bands, GPT-4 was less consistent in marking high-scoring responses (Z=–5.71–4.62, P<0.001). Overall, despite achieving substantial alignment with human raters in many cases, discrepancies across item types and a tendency to commit basic errors necessitate continued educator involvement to ensure grading accuracy.
Conclusion With optimized prompts, GPT-4 shows promise as a supportive tool for grading pharmacy students’ exam responses, particularly for objective tasks. However, its limitations—including errors and variability in grading high-scoring responses—require ongoing human oversight. Future research should explore advanced generative artificial intelligence models and broader assessment formats to further enhance grading reliability.
Purpose With Korea’s recent rapid change into a multicultural society, cultural competence is being emphasized as a core nursing competency. This study investigated the effects of a cultural nursing course that aimed to enhance the cultural competence of nursing students in Korea.
Methods This was a single-group pre- and post-comparison study. The subjects were 69 nursing students at Dongyang University who attended a cultural nursing course in 2015, of whom 62 students responded to the survey. The 13-week cultural nursing course was held for 2 hours a week. The methods of the course included small group activities, discussions and presentations, experiential learning, reflective activities, and lectures. Nursing students’ cultural competence was measured pre- and post-course with the Cultural Competence Scale for Korean Nurses, which contains 33 items scored on a 7-point Likert scale.
Results After completing the cultural nursing course, students’ total cultural competence scores increased, as did their scores in each category (cultural awareness, cultural knowledge, cultural sensitivity, and cultural skills) (P<0.001). There was no significant difference in cultural competence by gender (P<0.001).
Conclusion This cultural nursing course was found to be effective in enhancing the cultural competence of nursing students. Therefore, the educational program developed in this study can be extended to other university-level nursing programs in Korea.
