However, sufficient education on bioethics is not provided in the pediatric nursing domain of basic nursing education. The purpose of this research is to examine the current status of bioethics education in the pediatric nursing domain of basic nursing education and explore the challenges perceived by the pediatric nursing faculty regarding bioethics education. The research method was a questionnaire survey on 100 randomly selected pediatric nursing faculty members from nursing universities across Japan. The results revealed that although bioethics issues were considered important, the emphasis remained primarily on addressing bioethics as part of nursing that respects children’s rights. Furthermore, respondents expressed difficulties regarding teaching methods and content related to bioethics.展开更多

The study aimed to clarify the change in basic social competencies among nursing students by comparing their scores before and during the pandemic. Method: Retrospective data from 235 responses from 3rd-grade nursing students were analyzed. The data were separated into two groups—158 respondents before-pandemic and 77 respondents during-pandemic. Respondents were asked to complete a measurement scale two months after the beginning of the 3rd-grade module. Results: Our results showed the during-pandemic group’s averages were higher than the before-pandemic group’s. During the pandemic, nursing students using home-based online learning could not self-evaluate accurately because they could not practice in the field. Conclusion: Nursing students who were studying during the during-pandemic self-assessed themselves higher than those who were studying during the before-pandemic because they could not compare with the other students, and the results showed that misunderstandings may arise.展开更多

Nursing practice ability is one of the core abilities of nurse practitioners. Therefore, the teaching quality of this course is directly related to the quality of nursing work. To improve the teaching quality of practical course, the assessment reform of the “Basic Nursing Skills Practice” course was carried out among the nursing undergraduates to explore a reasonable and fair assessment mechanism. Method: In the assessment of “Basic Nursing Skills Practice” course, the assessment included individual skill operation assessment, virtual simulation assessment and team comprehensive skill assessment. The assessment proportion was adjusted from 100% for the final examination to 50% for the middle and final examinations respectively. The assessment method was changed from individual skills assessment at the end of the term to a combination of individual skills assessment at the midterm and virtual simulation assessment and team skills assessment at the end of the term. The method has changed from summative evaluation to a combination of formative evaluation and summative evaluation, and self-made questionnaire was used to investigate the effect. Results: After implementing the assessment reform, 86.84% of the students were satisfied with the assessment reform, and the percentage of students with scores above 80 reached 100%. The highest score is 93.0, while the lowest score is 83.0, and the average score was 88.0. Conclusions: High satisfaction of students with basic nursing skills examination reform promoted the learning effectiveness and professional emotions, cultivated comprehensive quality and ability, promoted the realization of talent training objectives.展开更多
