The current educational and technological environment in medical radiation science is dynamic. Educators must seek both proven and contemporary methods to ensure graduates are equipped for the clinical environment. This scoping review sought to assess the evidence regarding the value of problem-based learning (PBL) as part of medical radiation undergraduate curricula.
A systematic search of Medline, Emcare, and CINAHL was undertaken. Studies using both quantitative and qualitative methodologies were eligible if they reported the outcomes relating to PBL intervention for medical radiation science students in undergraduate education (diagnostic radiography, radiation therapy, or nuclear medicine). Outcomes included self-perceived benefits, disadvantages, and skills. Screening and data extraction was conducted independently by two reviewers.
Eleven studies were included. Data regarding perceived benefits, perceived disadvantages, and skills were gathered. Pre-post studies demonstrated statistically significant findings suggesting better preparedness and improved attitudes for PBL students. Across institutions globally, there is evidence suggesting PBL is positively received by medical radiation students. High satisfaction was experienced amongst participants. Negative feedback included lack of resources, limitations in realism, and issues associated with groupwork.
PBL may positively impact student satisfaction, knowledge acquisition, and skills, though this necessitates further research.
Medical radiation is an evolving discipline, and problem-based learning poses an educational tool to equip graduates with adaptive qualities.
医学放射科学目前的教育和技术环境是动态的。教育工作者必须寻求经过验证和现代的方法，以确保毕业生具备临床环境所需的能力。本范围综述旨在评估基于问题的学习（PBL）作为医学放射本科课程一部分的价值的证据。
对 Medline、Emcare 和 CINAHL 进行了系统搜索。如果研究报告了与医学放射科学本科生教育中 PBL 干预相关的结果（诊断放射学、放射治疗或核医学），则使用定量和定性方法的研究均符合条件。结果包括自我感知的益处、缺点和技能。两名审查员独立进行筛选和数据提取。
共纳入 11 项研究。收集了关于感知益处、感知缺点和技能的数据。前后研究表明，PBL 学生的准备情况更好，态度有所改善，具有统计学意义。在全球各个机构，有证据表明 PBL 受到医学放射学生的积极欢迎。参与者的满意度很高。负面反馈包括资源匮乏、现实性有限以及与小组合作相关的问题。
PBL 可能会对学生满意度、知识获取和技能产生积极影响，但这需要进一步研究。
医学放射是一个不断发展的学科，基于问题的学习是一种教育工具，可以使毕业生具备适应能力。
